Abstract

A catheter for use in an endoluminal delivery assembly includes a device holding region or element on which there is provided a plurality of flexible fingers extending outwardly therefrom. The fingers act to maintain a device to be deployed in the correct position on the catheter and act to resist deformation of the device during deployment.

Claims

1. A catheter element for an introducer, designed to carry a medical device to be implanted in a patient, the medical device comprising a structure with one or more interstices therein;

the catheter element including an elongate device support region on which a medical device can be located and at least one flexible member arranged on at least a portion of said support region, said flexible member extending radially outwardly from said support region and being partially deformable by a medical device carried on the catheter element so as to be at least partially locatable in at least one interstice of the medical device.

2. The catheter element according to claim 1, wherein there is provided a plurality of flexible elements in the form of fingers.

3. The catheter element according to claim 2, wherein the fingers are substantially round, oval or flat, in cross-section or any combination thereof.

4. The catheter element according to claim 2, wherein at least some of the fingers extend substantially perpendicularly to a longitudinal axis of the device.

5. The catheter element according to claim 2, wherein at least some of the fingers extend at an angle to the transverse direction of the device support region.

6. The catheter element according to claim 5, wherein the fingers that extend at an angle comprises an angle of between 20°

to 80°

in a direction towards or away from a distal end of the catheter.

7. The catheter element according to claim 2, wherein the fingers extend in a radial direction of the device support region.

8. The catheter element according to claim 2, wherein at least some of the fingers are substantially straight.

9. The catheter element according to claim 2, wherein at least some of the fingers are curved.

10. The catheter element according to claim 2, wherein at least some of the fingers have hooked ends.

11. The catheter element according to claim 2, wherein the fingers are formed from the same material as the elongate element.

12. The catheter element according to claim 2, wherein the fingers are formed from a material different from the elongate element and the catheter.

13. The catheter element according to claim 2, wherein the fingers are arranged on the elongate element in sets.

14. The catheter element according to claim 13, wherein the fingers are grouped in sets radially around and/or longitudinally along the device support region.

15. The catheter element according to any preceding claim 1, wherein the device support region is a portion of the catheter designed to hold the device to be implanted.

16. An introducer system including a catheter element according to claim 1, a sheath and a medical device to be deployed in a patient.

17. The introducer system according to claim 16, wherein the medical device is a stent, a stent graft, a vena cava filter or an occlusion device.

18. An introducer system including a catheter element designed to carry a medical device to be implanted in a patient, which medical device includes a structure with one or more interstices therein;

the catheter element including an elongate device support region on which a device can be located and a plurality of flexible members in the form of fingers arranged on at least a portion of said support region, said flexible members extending radially outwardly from said support region and being partially deformable by a said medical device carried on the catheter element so as to be at least partially locatable in the interstice or interstices of the medical device.

19. The introducer system according to claim 18, wherein at least some of the fingers extend at an angle that is transverse to the device support region

20. The introducer system according to claim 18, wherein at least some of the fingers are curved.

21. The introducer system according to claim 18, wherein at least some of the fingers have hooked ends.
