Abstract
Description
- 1. Field of the Invention
- The present invention is directed to a catheter, for example a retrieval or delivery catheter used in medical applications, which has an expandable end portion.
- 2. Discussion of the Background
- Catheters are well known medical devices used to facilitate various medical procedures, such as diagnostic or delivery procedures. Catheter tubes are inserted into a body of a patient for various medical procedures. For example, a catheter may be used in performing diagnostic procedures such as removing a sample from a body site of a patient. The catheter tube is used in this situation as the delivery vehicle for the medical instrument which removes the sample. Further, sophisticated medical implant devices, such as filters and stents, can be delivered and retrieved into and from the body site of the patient using a catheter.
- Generally, a catheter has a tube portion which is relatively stiff in both axial and radial directions to allow proper placement of the catheter in the patient's body, but which may be fitted with a distal soft tip which first contacts tissues in the patient. The soft tip is provided to minimise discomfort for the patient when the catheter is inserted into the patient. For example, WO-A-9808562 A describes a catheter with an insert molded catheter tip. However, there are constraints on the use of such catheters in that such catheters can only be relatively small sized, and thus can only be used to retrieve and deliver relatively small samples and medical devices.
- Accordingly, one object of the present invention is to provide a novel catheter which can be used to retrieve larger objects and deliver and retrieve larger medical devices than in the background art.
- A further object of the present invention is to provide a novel catheter which can accommodate an article with a slightly larger dimension than that of a main catheter tube itself.
- The novel catheter of the present invention achieves these and other objects by including a portion near a distal tip end which is expandable in size in a radial direction to accommodate larger size samples or medical devices. The catheter includes reinforcement means to enhance the axial strength of the tip while facilitating radial expansion of the tip to accommodate an article.
- As a further feature, the novel catheter of the present invention can further include reinforcing portions in the expandable portion to enhance strength in the axial direction, while still allowing expansion in the radial direction.
- Most preferably the tip is a soft tip of flexible material.
- In a preferred embodiment the reinforcement means comprises an extension means extending from the catheter tube portion. Preferably the tip includes a free distal end and the extension means terminates at a position that is axially spaced back from the free end of the tip.
- In one embodiment of the invention the extension means comprises at least one extension member extending from said catheter tube portion into said expandable tip.
- Preferably the extension means comprises a plurality of extension members extending from said catheter tube portion into said expandable tip. To provide a gradual change in the axial reinforcement preferably said at least one extension member is tapered toward a leading portion of said expandable tip.
- Axial reinforcement and radial expansion is facilitated particularly when said plurality of extension members are equi-spaced in the direction of said expandable member.
- Preferably said plurality of extension members are tapered toward a leading portion of said expandable member.
- For ease of manufacture while providing the desired reinforcement characteristics preferably the number of said plurality of extension members is four.
- To provide atraumatic transition to the soft tip preferably said at least one extension member includes a radiused tip. Ideally, said plurality of extension members each include a radiused tip.
- In addition, for ease of passage of an article into or out of the tip preferably the tip has a free end which is rounded.
- In a preferred embodiment the tip has a free end which is rounded for ease of passage of the tip through a body passageway such as the vasculature.
- Preferably the tip comprises a tubular sleeve of flexible material. For ease of manufacture and to provide a smooth transition preferably the sleeve is attached to the catheter tube portion by heating.
- Ideally to provide a smooth transition the tip has an outer diameter which is approximately the same dimension as the outer diameter of the catheter tube portion.
- In one aspect the invention provides a retrieval catheter for retrieving an article such as a filter comprising a catheter tube portion and a tip extending axially from the catheter tube portion, the tip being flexible relative to the catheter tube portion, characterised in that the catheter includes reinforcement means to enhance the axial strength of the tip while facilitating radial expansion of the tip to accommodate an article in the tip. Usually the article to be retrieved has a larger dimension then that of the normal internal dimension of the tip.
- In one embodiment of the invention the tip is movable from a delivery configuration in which the outer diameter of the tip is approximately of the same dimension as the outer diameter of the catheter portion to which it is attached, to an expandable position as an article is received in the tip.
- For ease of use, preferably the tip is progressively movable to the expanded position in response to receiving an article in the tip.
- The invention also provides a catheter tube portion having a tip extending axially from the catheter tube portion, in which the catheter tube portion includes reinforcement means to enhance the axial strength of the tip while facilitating radial expansion of the tip to accommodate an article in the tip.
- The invention will be more clearly understood by reference to the following detailed description when considered in conjunction with the accompanying drawings, wherein:
- FIG. 1 is an overall view of the novel catheter of the present invention used with an introducer;
- FIG. 2 shows a more detailed view of a tip portion of the catheter of FIG. 1;
- FIGS.3(a) and 3(b) are cross sectional views of the tip portion of the catheter on the lines IIIa-IIIa and IIIb-IIIb respectively of FIG. 2;
- FIG. 4(a) is an exploded view of the tip portion of the catheter of the present invention;
- FIG. 4(b) is a cross sectional view on an enlarged scale of a distal end of the tip portion of the catheter;
- FIGS.5(a) to 5(d) are diagrammatic views showing one operation of the catheter; and
- FIG. 6 is a scale drawing, as an example, of an actual implementation of the novel catheter of the present invention.
- Referring to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIG. 1 thereof, the
overall device 1 is an introducer, e.g. a percutaneous introducer, with acatheter portion 2. FIG. 1 illustrates thecatheter portion 2 according to the present invention, for example a retrieval catheter, which is attached to an introducer having ahub portion 20 and aside lead tube 21 which leads into thehub portion 20. A medical instrument to be inserted into a patient is placed through thehub portion 20. This medical instrument placed through thehub portion 20 may be, as examples, a retrieval element to retrieve a sample, a clot or previously inserted medical device such as a stent or filter from a patient's body, or a delivery element to deliver a medical device to a patient's body. - The
catheter 2 may also be used to deliver or retrieve another catheter. Thecatheter portion 2 of FIG. 1 includes acatheter tube portion 5 which is relatively rigid in both the axial and radial directions to facilitate delivery of thecatheter tube portion 5 through a lumen. That is, thecatheter tube portion 5 is a portion actually inserted into the patient. - The
catheter portion 2 of the present invention further includes an expandablesoft tip portion 6 with adistal tip area 6 a. Theexpandable tip 6 is in the form of a sleeve which has an outer diameter which is nominally the same as the outer diameter of thecatheter tube portion 5. The distalsoft tip area 6 a initially contacts tissues of the patient as thecatheter tube portion 5 is inserted into the patient, and minimises discomfort in the patient by virtue of its softness. The expandablesoft tip portion 6 is flexible in both the axial and radial directions, and particularly is expandable in the radial direction. Thisexpandable tip portion 6 may be made of a radiopaque or non-radiopaque material. Examples of materials for theexpandable tip portion 6 include PEBA (polyether block polyamide), nylon, polyurethane or polyethylene. - FIGS. 2, 3 and4 provide further details of the
catheter portion 2 including the expandablesoft portion 6. Thecatheter portion 2 includesextension legs 10 formed inside of theexpandable portion 6. That is, thecatheter tube portion 5 is processed to formextension legs 10 at the leading edge of thecatheter tube portion 5. Theextension legs 10 can be formed in thecatheter tube portion 5 by, for example, cuttingcatheter tube portion 5 using a punch and die set with a profile to achieve a desired taper in theextension legs 10. Theextension legs 10 provide a reinforcement in the axial direction of theexpandable portion 6 over their length to enhance the strength ofexpandable portion 6 in the axial direction, while still providing expansion in the radial direction. In the embodiment shown in FIGS. 2-4 fourextension legs 10 are equi-spaced around theexpandable portion 6 to provide support in the axial direction and uniform flexibility in the radial direction. Theseextension legs 10 are tapered towards the free end of theexpandable portion 6 to provide a gradually increasing controlled axial flexibility to allow thecatheter tube portion 5 to be comfortably guided into the patient. - The
expandable portion 6, which as noted above can be formed of a radiopaque or non-radiopaque material such as PEBA, nylon, polyurethane or polyethylene, can be secured to the maincatheter tube portion 5 by heating such as by RF (radio frequency) welding theexpandable portion 6 to the maincatheter tube portion 5. On heating, theextension legs 10 merge into theexpandable portion 6. - It will be noted that the expandable
soft portion 6 extends distally beyond the axial extent of theextension legs 10 to provide the distalsoft tip 6 a which is not axially reinforced. Thesoft tip 6 a has a free end that is rounded internally at 23 for ease of passage of an article 3, and is also rounded externally at 24 for ease of atraumatic passage of the tip through a body passageway such as the vasculature. - FIG. 6 shows an actual implementation of the
catheter portion 2 in the present invention.Element 12 shows distal tips of theextension legs 10, andelement 13 shows proximal tips of theextension legs 10, whichtips tips extension legs 10 can be rounded to prevent creating a sharp edge, and thereby generating a weak point in thesoft tip area 6 a or theexpandable portion 6. Generating a weak point in theexpandable portion 6 could result in a tear in the soft tip, and if thetips extension legs 10 are radiused such a weak point and resulting tear may be prevented. Typical dimensions in millimeters are as follows:11 18.00 ± 1.50 12 15.00 ± 0.25 13 0.70 - FIGS.5(a) to 5(d) show the
catheter 2 of the present invention in use as a retrieval catheter as an example of one use ofcatheter 2. As shown in FIG. 5(a), an article 3 for retrieval, for example a sample or clot within a patient or a medical device such as a stent or filter previously inserted in the patient, is approached by thecatheter tube portion 5. A retrieval device may be inserted in theintroducer 1 and through thehub 20, through thecatheter tube portion 5, and then through theexpandable portion 6, to contact the sample 3. Alternatively the article 3, especially when in the form of a medical device such as a filter, may be attached, on introduction, to aguide wire 11 as shown in FIG. 5(a). Th retrieval device then retrieves the article 3 into theexpandable portion 6 of thecatheter portion 2 as shown in FIGS. 5(b) to 5(d). The article 3 is first pulled back by pulling the guide wire and engages thedistal tip 6 a which is not reinforced and expands radially to receive the proximal end of the article 3. As the article 3 is drawn further back into theexpandable portion 6 theexpandable portion 6 expands radially outwardly. However theexpandable portion 6 is gradually axially reinforced by theextension legs 10 to smooth the capture of the article 3. Thisexpandable portion 6 extending axially from thecatheter tube portion 5 is flexible relative to thecatheter tube portion 5. The catheter portion includes reinforcement means to enhance the axial strength of theexpandable portion 6 while facilitating radial expansion of the tip to accommodate an article 3 in theexpandable portion 6. The tip expands to accommodate the article 3. As noted above, theextension legs 10 provide some support in the axial direction, but still allow expansion in the radial direction, to thereby allowexpandable portion 6 to expand to allow the article 3 to be drawn into theexpandable portion 6. Thecatheter tube portion 5 can then be removed from the patient with the article 3 housed therein. - In this way, this operation in the present invention allows a sample or device3 which may be larger than the catheter tube-
portion 5 to be retrieved from a patient. A medical device which may be larger than thecatheter tube portion 5 can also be delivered to a patient in a similar manner. - Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims the present invention may be practised otherwise than as specifically disclosed therein.
