- This invention relates to catheter-based implantable medical devices for occluding the flow of blood at a preselected position within a blood vessel, and more particularly to an aneurysm embolic device which serves to fill an aneurysm with an occlusive member thereby preventing the flow of blood into the aneurysm.
- Aneurysms typically take the form of a balloon-like swelling in the wall of a vessel which generally results from a weakness in the vessel wall. If untreated, aneurysms may continue expanding until they burst thereby causing hemorrhaging to occur. If, for example, an aneurysm is present within an artery of the brain, and the aneurysm should burst with resulting cranial hemorrhaging, death could occur.
- Aneurysms result from many different causes; however, most aneurysms are caused as a result of a degenerative disease which damages the muscular coating of a vessel with resulting congenital deficiency in the muscular wall of the vessel.
- stents are expanded to the proper size by inflating a balloon catheter, referred to as balloon expandable stents, while other stents are designed to elastically expand in a self-expanding manner.
- Balloon expandable stents and self-expanding stents are generally delivered to a preselected position through a delivery catheter. They are moved out of the distal end of the delivery catheter, are expanded and then are released to remain within the vessel.

- Another method for treating aneurysms is that of using a microcatheter for placing multiple very small embolic coils within the aneurysm with the expectation that fibrous material will become entrapped in the embolic coils to thereby stabilize the coils within the aneurysm.

Abstract
Description
- This patent application is a divisional patent application of U.S. patent application Ser. No. 10/295,196 (Attorney Docket No. CRD0980USNP), filed on Nov. 15, 2002, entitled, “Aneurysm Embolic Device With An Occlusive Member,” which is a nonprovisional patent application of U.S. provisional patent application Ser. No. 60/335,489, filed on Nov. 15, 2001.
- 1. Field of the Invention
- This invention relates to catheter-based implantable medical devices for occluding the flow of blood at a preselected position within a blood vessel, and more particularly to an aneurysm embolic device which serves to fill an aneurysm with an occlusive member thereby preventing the flow of blood into the aneurysm.
- 2. Description of the Prior Art
- Aneurysms typically take the form of a balloon-like swelling in the wall of a vessel which generally results from a weakness in the vessel wall. If untreated, aneurysms may continue expanding until they burst thereby causing hemorrhaging to occur. If, for example, an aneurysm is present within an artery of the brain, and the aneurysm should burst with resulting cranial hemorrhaging, death could occur.
- Aneurysms result from many different causes; however, most aneurysms are caused as a result of a degenerative disease which damages the muscular coating of a vessel with resulting congenital deficiency in the muscular wall of the vessel.
- Various attempts have been made to treat aneurysms without resorting to surgery, such as the placement of sleeves or stents into the vessel and across the region where the aneurysm occurs. Such devices maintain blood flow through the vessel while reducing blood pressure applied to the interior of the aneurysm. Certain types of stents are expanded to the proper size by inflating a balloon catheter, referred to as balloon expandable stents, while other stents are designed to elastically expand in a self-expanding manner. Balloon expandable stents and self-expanding stents are generally delivered to a preselected position through a delivery catheter. They are moved out of the distal end of the delivery catheter, are expanded and then are released to remain within the vessel. One example of a delivery catheter system which may be used to place a stent within a vessel is disclosed in U.S. Pat. No. 6,254,612 entitled, “Hydraulic Stent Deployment System” and assigned to the same assignee as the present patent application. The stent deployment system disclosed in this patent, which is incorporated herein by reference, includes a deployment catheter having a distal tip for retaining a stent in order to transport the stent to a preselected position within the vessel. Once the stent has been properly positioned, a hydraulic control mechanism is used to release the stent from the distal end of the catheter and deposit the stent at the preselected location within the vessel.
- Another method for treating aneurysms, particularly where the aneurysm occurs in a very small vessel of the brain, is that of using a microcatheter for placing multiple very small embolic coils within the aneurysm with the expectation that fibrous material will become entrapped in the embolic coils to thereby stabilize the coils within the aneurysm. With this technique, it is possible to fill the aneurysm with embolic coils thereby sealing off the walls of the aneurysm from the pressure of blood which exist in the adjacent vessel.
- Examples of a catheter deployment system for depositing embolic coils into an aneurysm are disclosed in U.S. Pat. No. 6,063,100, entitled, “Embolic Coil Deployment System With Improved Embolic Coil”; U.S. Pat. No. 6,183,491 entitled, “Embolic Coil Deployment System With Improved Embolic Coil”; and U.S. Pat. No. 6,113,622 entitled, “Embolic Coil Hydraulic Deployment System,” all of which are assigned to the assignee of the present patent application. These patents, and the disclosure thereof, are incorporated herein by reference and made a part of the present patent application.
- One modification to the technique of placing embolic coils within an aneurysm is that of using a stent or scaffold like structure which is placed across the aneurysm by having passageways within the structures so that embolic coils may be passed through the structure and into the aneurysm. The stent, or scaffold like structure, serves to hold the embolic coils within the stent until such time as these coils become stabilized by fibrous material growing into the coils. One example of such a structure, or stent, for use in this form of treatment of an aneurysm is disclosed in U.S. Pat. No. 6,063,111 entitled, “Stent Aneurysm Treatment System And Method.”
- Still another method of treating an aneurysm, and in particular an aneurysm within the brain, is that of placing a mesh covered support structure within the aneurysm itself and subsequently expanding the mesh covered structure in order to fill the entire aneurysm. Such a structure serves to fill the aneurysm and thereby prevent blood flowing in an adjacent vessel from entering the aneurysm. These devices, referred to as occlusion devices, serve to prevent the pressure of blood flowing through a vessel from being applied to the walls of the aneurysm thereby preventing, or reducing, the further expansion of the aneurysm.
- One such aneurysm occlusion or embolization device is disclosed in U.S. patent application Ser. No. 09/505,231 entitled, “Aneurysm Embolization Device,” and assigned to the same assignee as the present patent application.
- Even with the existing treatment techniques for aneurysms, and in particular for aneurysm which exists within the brain, there is a need for other forms of aneurysm treatment that may be easily delivered to a vascular site through a very small catheter, and in particular for a device which serves to seal off the flow of blood between an adjacent vessel and an aneurysm.
- In accordance with one aspect of the present invention, there is provided a catheter-based aneurysm embolic system for occluding the flow of blood into an aneurysm. The aneurysm embolic system includes a deployment catheter. The embolic system also includes an introducer sheath which is disposed about the deployment catheter. The embolic system further includes an aneurysm embolic device which includes an expandable sealing member and an occlusive member which takes the form of an expandable foam material.
- The sealing member is preferably an expandable flexible disk and is comprised of a circular joining member located at the center of the sealing member. A plurality of reinforcing spokes are attached to the circular joining member and extend radially outward from the circular joining member. A thin circular membrane is bonded to the circular joining member and the reinforcing spokes, and an occlusive member, such as an expandable foam, is carried by the sealing member. In addition, a headpiece is attached to the center of the sealing member and is disposed in the distal end of the deployment catheter. When the aneurysm embolic device is placed at the neck of an aneurysm the sealing member may be expanded to seal the mouth of the aneurysm and simultaneously permit deployment of the occlusive member within the aneurysm to substantially fill the aneurysm.
- In accordance with another aspect of the present invention, the occlusive member is formed of a material such that when the sealing member is deployed within an aneurysm the occlusive member may be released within the aneurysm and the material expands to substantially fill the aneurysm.
- In accordance with a further aspect of the present invention, the aneurysm embolic device includes first and second circular membranes having surfaces which are bonded together and which encapsulate the circular joining member and the reinforcing spokes. The circular membrane is preferably made from a blood-impermeable polymer material.
- In accordance with still another aspect of the present invention, the expandable sealing member is slightly cupped to form convex and concave sides. The occlusive member is attached to the concave side of the sealing member.
- In accordance with another aspect of the present invention, the expandable sealing member is tubular shaped when the sealing member is disposed within the lumen of the sheath.

FIG. 1 illustrates an aneurysmembolic device 10, adeployment catheter 12, and asheath 14 in accordance with the present invention. Thedeployment catheter 12 is an elongated tube with alumen 16. Preferably, theproximal section 18 of thedeployment catheter 12 is formed of a pellethane material having a durometer in a range of about 60 D to 75 D. Theproximal section 18 is sufficiently flexible to transverse the vasculature of the human body, but is sufficiently rigid so that it can be pushed distally through thesheath 14. Thedistal section 20 of thedeployment catheter 12 is preferably formed of a pellethane material having a durometer of between 25 D and 55 D with a durometer of 40 D being the preferred durometer. - The
deployment catheter 12 also includes awinged hub 22 coupled to theproximal section 18 of thedeployment catheter 12. Thewinged hub 22 may be made from plastic and aids in the insertion of thedeployment catheter 12 into the vasculature of the body. Thesheath 14 is also an elongated tube with alumen 24 extending therethrough. Thesheath 14 is preferably formed of a polymer material and is sufficiently flexible to transverse the vasculature of the body. Thedeployment catheter 12 and aneurysmembolic device 10 are disposed within thelumen 24 of thesheath 14. The diameter of thelumen 24 on thesheath 14 is sufficiently small enough so that the aneurysmembolic device 10 is forced to a compressed configuration. The aneurysmembolic device 10 is attached to thedistal end 26 of thedeployment catheter 12 by way of aheadpiece 28 which is described in more detail below. -
FIG. 2 illustrates the aneurysmembolic device 10 in a compressed configuration within thelumen 24 of thesheath 14. The aneurysmembolic device 10 includes anexpandable sealing member 30. When compressed, theexpandable sealing member 30 is generally tube-shaped such that the aneurysmembolic device 10 may be disposed within asheath 14. The aneurysmembolic device 10 also includes a plurality of longitudinal reinforcingspokes 32 within theexpandable sealing member 30. These reinforcingspokes 32 are discussed in the description ofFIG. 3 a. Theheadpiece 28 is attached to the sealingmember 30 and is disposed within thedistal end 26 of thedeployment catheter 12. Theheadpiece 28 forms a fluid tight seal in thedistal end 26 of thedeployment catheter 12 so that when a fluid pressure is applied to thelumen 16 of thedeployment catheter 12, theheadpiece 28 is released from thedistal end 26 of thedeployment catheter 12. -

The diameter of the sealingmember 30 is preferably slightly larger than the diameter of an opening of theaneurysm 34. Typically, the sealingmember 30 will seal the opening of a 5 to 6 mm aneurysm, but may be increased in size to seal aneurysms in the range of 3 to 20 mm. - The
occlusive member 38 is compressed when the aneurysmembolic device 10 is disposed within thelumen 24 of thesheath 14. When the aneurysmembolic device 10 is deployed, theocclusive member 38 is released into ananeurysm 34 as illustrated inFIG. 5 . The sealingmember 30 occludes the mouth of theaneurysm 34 and prevents theocclusive member 38 from exiting theaneurysm 34. Theocclusive member 38 is preferably polyvinyl alcohol, but may also be nylon fibers, biocompatible foam, biocompatible adhesive, embolic coils, or an expandable material, such as for example, hydrogel. As theocclusive member 38 is deployed within theaneurysm 34, theconvex side 36 of the sealingmember 30 forms a generally fluid tight seal around the interior opening of theaneurysm 34. Theocclusive member 38 may be anchored to the aneurysmembolic device 10 or preferably may rest freely within the compressed aneurysmembolic device 10 until deployed. -
FIG. 3 a illustrates the aneurysmembolic device 10 in a deployed configuration as viewed from within a blood vessel adjacent to theaneurysm 34. A thincircular joining member 44 is disposed at thecenter 46 of the sealingmember 30. The circular joiningmember 44 may be made of stainless steel, titanium, platinum, or a polymer material, but the preferred material is Nitinol. A plurality of reinforcingspokes 32 extends radially outward from the circular joiningmember 44. The proximal ends 48 of each reinforcing spoke are attached to the circular joiningmember 44, while the distal ends 50 of each reinforcing spoke 32 extend generally to theouter edge 52 of the sealingmember 30. - Preferably, the reinforcing
spokes 32 may be made of the same material as the circular joiningmember 44. The reinforcingspokes 32 may take the form of cylindrical rods, flat battens, or rectangular rods. Preferably, the circular joiningmember 44 and the reinforcingspokes 32 are one unitary structure laser cut from Nitinol. Theheadpiece 28 may also be cut from the same unitary Nitinol structure. The circular joiningmember 44 and the reinforcingspokes 32 may include radiopaque markers for use during fluoroscopic visualization. -
FIG. 3 b illustrates the slightly cupped configuration of theexpandable sealing member 30. The curvature may be created by a normally curved sealingmember 30, but preferably, the curvature is formed by normally curved reinforcingspokes 32. Two thincircular membranes 54 are bonded to the reinforcingspokes 32 and the circular joining member 44 (not shown). Preferably, onecircular membrane 54 may be attached to the reinforcingspokes 32 on theconcave side 40 of the sealingmember 30 while the othercircular membrane 54 may be attached to the reinforcingspokes 32 on theconvex side 36 of the sealingmember 30, such that thecircular membranes 54 encapsulate the reinforcingspokes 32 and the circular joiningmember 44. Theocclusive member 38 is disposed on theconcave side 40 of theexpandable sealing member 30. -
FIGS. 4 through 6 illustrate the deployment of the aneurysmembolic device 10 within theaneurysm 34.FIG. 4 illustrates the aneurysmembolic device 10, thedeployment catheter 12, andsheath 14 being positioned within theblood vessel 42 adjacent to theaneurysm 34 to be treated. Theheadpiece 28 of the aneurysmembolic device 10 is disposed within thelumen 16 of thedeployment catheter 12, and the aneurysmembolic device 10 is disposed within thesheath 14 so that the sealingmember 30 is in a compressed configuration. This allows the aneurysmembolic device 10 to hold theocclusive member 38 and to be transported through the narrow vasculature. Adelivery catheter 56 is positioned within the vasculature to guide thedeployment catheter 12 to the preselectedaneurysm 34 and to protect the vasculature from damage or puncture. -
FIG. 5 illustrates thedistal end 58 of thesheath 14 being positioned at the mouth of theaneurysm 34. Thedeployment catheter 12 is moved distally causing the sealingmember 30 of the aneurysmembolic device 10 to exit thelumen 24 of thesheath 14. Without thesheath 14 maintaining the aneurysmembolic device 10 in a compressed configuration, the sealingmember 30 andocclusive member 38 expand within theaneurysm 34. The thincircular membranes 54 of the sealingmember 30 contact the wall of theaneurysm 34 and form a generally fluid tight seal. -
FIG. 6 illustrates fluid pressure being applied to thelumen 16 of thedeployment catheter 12 thereby causing theheadpiece 28 of the aneurysmembolic device 10 to exit thedistal end 26 of thedeployment catheter 12. The expandedocclusive member 38 holds the sealingmember 30 in position, and blood is generally prevented from flowing into theaneurysm 34. - A novel system has been disclosed in which an aneurysm embolic device is used to occlude the flow of blood within an aneurysm. Although a preferred embodiment of the invention has been described, it is to be understood that various modifications may be made by those skilled in the art without departing from the scope of the present invention. For example, there are many variations and modifications of the occlusive member, including helically wound embolic coils or other types of vascular occlusive devices, such as balloons, radiopaque fluids, and liquid medications.
- These and other modifications would be apparent to those having ordinary skill in the art to which this invention relates and are intended to be within the scope of the claims which follow.
