Abstract
The invention describes a method of treating a patient's left atrial appendage through the pericardial space. The process takes place through the pericardial space from an access point outside the pericardium or pericardial space.
Description
- The present invention relates generally to devices and techniques for remodeling the atrial appendage of a mammal. The process takes place through the pericardial space from an access point outside the pericardium or pericardial space.
- The atrial appendage is an anatomic feature of the left atrium of the human heart. It is widely believed that atrial fibrillation results in a pooling of blood in the atrial appendage which results in clots.
- The surgical removal of the atrial appendage through a limited thoracotomy has been proposed by Johnson in U.S. Pat. No. 5,306,234. However, the surgical removal of the appendage remains problematic since the surgical intervention occurs under general anesthesia and is considered major surgery. It should also be realized that even a transluminal minimally invasive approach from inside the heart is problematic since such an approach requires an implantable closure device and has the risk of acute stroke. Typically any closure device left in contact with the interior of the heart is potentially a thromobogenic surface.
- For these reasons among others there is a continuing need to improve techniques for occluding or removing the left atrial appendage.
- In contrast to the prior art, the present invention teaches devices and methods of using the devices to remodel the atrial appendage from locations outside the heart but within the pericardial space. In use, the pericardial space is accessed via the chest wall below the rib cage and an endoscope is inserted. It is preferred to perform the process steps under visual guidance although robotic and other location technologies may be used in the alternative. The preferred treatment for the appendage is “wet cautery” where the size and therefore the volume of the appendage is reduced. An alternate preferred device cuts and cauterizes while removing the appendage. Other surgical techniques are useful as well including conventional electrosurgery and cautery and conventional suture and staple techniques. In all instances the volume of the appendage is reduced and in some approaches tissue is removed as well.
- The invention is illustrated in the figures where like reference numeral represent identical structure throughout the several views wherein:
- FIG. 1 is a schematic diagram of the patient's chest cavity;
- FIG. 2 is a schematic diagram of pericardial access process and device;
- FIG. 3 is a schematic diagram of pericardial space visualization process and device;
- FIG. 4 is a schematic diagram of pericardial space electrocautery process and device;
- FIG. 5 is a schematic diagram of an electrocautery process and device;
- FIG. 6 is a schematic diagram of an electrocautery process and device;
- FIG. 7 is a schematic diagram of an endoscopic suture placement process; and
- FIG. 8 is a schematic diagram of an endoscopic staple placement process.
- FIG. 1 shows the
patients heart 10 located within the patient'schest cavity 12. Theribs 14 andskin 16 show the boundary of thechest cavity 12. The left atrial appendage (LAA) 18 is exaggerated in size to facilitate the description of the invention. Theheart 10 chambers lie within the so-calledpericardium 20, which is shown in an exaggerated scale. Thepericardium 20 is a bag like structure that surrounds the heart. It is attached to the great vessels at the “top” of the heart and it completely encircles the ventricles and the atrium of the heart. Thepericardium 20 provides a low friction surface surrounding the heart that permits motion of the heart. In essence the pericardium allows the heart to “beat” without disturbing other near-by organs. - The processes of the invention permit the pericardium to remain “intact”. Although several opening to the pericardial space are illustrated it is emphasized that the smaller the number of “holes” in the pericardium are preferred.
- FIG. 2 shows initial access to the pericardial space though the use of a
pericardial access device 22, which is described in more detail in U.S. Pat. No. 5,827,216 among others. This patent is incorporated by reference herein and the commercially available device is sold under the trademark “Perducer”. The Perducer is preferred but alternate devices such as that taught by U.S. Pat. No. 5,931,810 could be freely substituted for the Perducer device. If multiple access points are required for a particular patient the two devices may be used together. - The
preferred device 22 has an aperture at itsdistal end 24 that allows aspiration of thepericardium 20 into the device. An illustrative source of vacuum is shown as the physician operatedsyringe 26. The aspirated tissue drawn into thedevice 22 can be pierced by theneedle 28. Theneedle 28 can be translated toward the aspirated tissue by pushing on the proximal end of theneedle 28. - A
guidewire 30 can next be inserted through the lumen of theneedle 28. With the guidewire in the pericardial space, the physician can withdraw the needle and use the guidewire to insert a catheter or other device. The access procedure described may be repeated to provide for multiple access sites or locations into the pericardial space. Although the device shown is preferred it should be recognized that other devices may be used as well. - FIG. 3 shows two access sites labeled50 and 52 respectively. A
guide catheter 40 has been introduced into thepericardial space 42. This access site or port permits access by theendoscope 46 which includes acamera 48 and adisplay system 52. Together these devices provide a visualization system allows visual navigation and manipulation of additional surgical tools in thepericardium 20. Although this visualization system is not seen in the remaining drawings its use should be presumed and the deletion from the figure is done to clarify the remaining drawings. It should be noted that most conventional endoscopes in use today have laparoscopic tool access ports built into the device and many steps of the invention can be carried out trough the scope rather than through a separate access site. However, it is expected that a typical atrial appendage reduction would require two sites, with one devoted to the introduction of a endoscope. - FIG. 4 shows a snare like
electrocautery tool 60 introduced into thepericardial space 42. Thedistal loop 64 has been navigated visually to “lasso” the atrial appendage. In the device seen in FIG. 4, one end of thesnare loop 64 is attached to atubular body 63 while the other end is carried through the lumen of thetubular body 63 and attached to a slidinghandle 15. A fixedhandle 17 is attached to thetubular body 63. Traction applied to thesnare loop 64 by moving the sliding handle relative to the fixedhandle 17 captures theappendage 18. The application of electrical energy (RF) from theelectrocautery unit 70 can either remove or close the atrial appendage. It is important to note that this closure process may be essentially bloodless and may be performed under direct visualization through the endoscope (FIG. 3). This process is an example of “dry” cautery as opposed to “wet” cautery described in connection with FIG. 6. Although the snare like device is preferred there are several commercially available products that can also be used for this step including the loop excision electrodes sold by ValleyLab of Colorado. In general, any specific surgeon may prefer to use other familiar tools for the process. Typically, theelectrosurgery unit 70 will be connected between theloop 64 and a patient ground depicted as 71. The physician may activate the hand or foot switch 73 to dissect the appendage. - FIG. 5 shows the
snare loop 64 isolating theatrial appendage 18 prior to the applicant of electrical energy. In the figure the physician my grasp an insulator handle and theconnection 19 may not be attached to thegenerator 70 until after the lasso procedure has been accomplished. Although the loop electrocautery device is preferred it should be noted that the conventional unipolar or bipolar cautery scissors such as those illustrated asdevice 13 may be used to cut off the appendage. - FIG. 6 shows the use of “wet” electrocautery to “reduce” the atrial appendage. In this procedure the
electrical catheter 80 is irrigated by a fluid flow of saline or otherconductive fluid 81. This wet electrode applies the energy over a wider surface area as a consequence heat is supplied preferentially to the LAA. It is expected that the application of heat will cause the appendage to reduce in size substantially. Fluid assisted electrocautery is known from U.S. Pat. No. 6,063,081 among others. - FIG. 7 shows an alternate method of closing off the atrial appendage. In this situation a
suture 90 has been formed into aloop 92 and passed over the atrial appendage. Alaparoscopic knot pusher 94 is passed down one leg of thesuture 90 to place and tighten a knot formed in the suture. The use of a suture may be preferred given the size and shape of theappendage 18. - FIG. 8 illustrates an alternate closure device and process. In this figure a laparoscopic stapler is used to place one or more staples to close off the atrial appendage. In the figure the
tool 98 has been used to place one staple seen asstaple 97 closing off the appendage.
