Abstract

A delivery system for delivering a prosthesis includes a catheter and a selectable tip kit having a plurality of tips. Each tip is uniquely shaped, i.e., has a particular shape different than the shape of all the other tips, and each tip is better suited for some procedures than for others. One of the tips is selected by the physician as being particularly well suited for the procedure to be performed. The selected tip is non-removably attached to the catheter and the remaining tips are discarded. This allows the delivery system to be customizable to each procedure, putting the physician in control of the case. This provides a case specific delivery system for the physicians to use and at a very low expense and with minimal additional engineering.

Claims

1. A delivery system comprising:

a catheter comprising a tip attachment boss; and

a selectable tip kit comprising a plurality of uniquely shaped tips, each tip being configured to snap onto the tip attachment boss.

2. The delivery system of claim 1 wherein the selectable tip kit comprises a container containing the tips.

3. The delivery system of claim 1 wherein the tips comprise a first tip and a second tip, the first tip being longer than the second tip.

4. The delivery system of claim 1 wherein the tips comprise a first tip and a second tip, the first tip being thinner than the second tip.

5. The delivery system of claim 1 wherein each tip includes a snap, the snap configured to snap onto the tip attachment boss to mount the tip to the catheter.

6. The delivery system of claim 1 wherein the snap in each tip is identical.

7. The delivery system of claim 1 wherein the catheter comprises:

a sheath; and

a prosthesis within the sheath.

8. The delivery system of claim 1 wherein the tip attachment boss is at a distal end of the catheter.

9. A delivery system comprising:

a catheter comprising an attachment boss sleeve comprising;

a shaft having an outer diameter; and

a flange having an outer diameter; and

a tip separated from the catheter, the tip comprising;

a shaft opening having a diameter equal to the outer diameter to the shaft; and

a flange opening having a diameter equal to the outer diameter of the flange.

10. The delivery system of claim 9 wherein the outer diameter of the shaft is less than the outer diameter of the flange.

11. The delivery system of claim 10 wherein the tip comprises a snap at the shaft opening.

12. The delivery system of claim 10 wherein the snap is configured to expand around the flange and then snap around the shaft.

13. The delivery system of claim 9 wherein the tip comprises a variable diameter opening, the variable diameter opening comprising the shaft opening and the flange opening.

14. The delivery system of claim 13 wherein the variable diameter opening further comprises a guide wire opening.

15. The delivery system of claim 14 wherein the variable diameter opening further comprises a stop opening.

16. A method comprising:

providing a delivery system comprising a catheter and a selectable tip kit comprising a plurality of uniquely shaped tips;

selecting one tip of the tips; and

attaching the one tip to the catheter.

17. The method of claim 16 wherein the attaching comprises non-removably attaching the one tip.

18. The method of claim 16 wherein the attaching the one tip comprises snapping the one tip to an attachment boss sleeve of the catheter.

19. The method of claim 16 wherein the tips are a one-time use.

20. The method of claim 19 further comprising discarding all the tips except the one tip attached to the catheter.
