Abstract

A system for deploying an implantable medical device into a body lumen is disclosed. The system comprises a catheter having functional zones for stability, protection, flexibility, trackability and pushability. The system further comprises a device for deploying an implantable medical device with the catheter. A method for deploying an implantable medical device into a body lumen using the system is also disclosed.

Claims

1-15. -15. (canceled)

16. A kit comprising:

a catheter for deploying an implantable medical device, the catheter having a tip at its distal end and a connector at its proximate end and comprising a stabilization zone proximate to the tip, a protection zone proximate to the stabilization zone, a flexibility zone proximate to the protection zone, a pushability zone proximate to the flexibility zone and a strain relief area between the pushability zone and the connector, and

an advancing device, the advancing device comprising;

a base member comprising

a base handle; and

a deployment extension having a distal end and a proximate end, the proximate end is connected to the base handle;

a first tubular member that fits over the deployment extension and is longitudinally slidable over the deployment extension, the first tubular member comprising;

a first tubular body with a distal end and a proximal end; and

a first handle for controlling movement of the first tubular member; and

a second tubular member that fits over the first tubular member and is longitudinally slidable over the first tubular member, the second tubular member comprising;

a second tubular body with a distal end and a proximal end; and

a second handle for controlling movement of the second tubular member, wherein the first handle is located between the base handle and the second

handle and wherein the distal ends of the deployment extension, the first tubular body, and the second tubular body are adapted to deploy the implantable medical device.

17. The kit of claim 16, further comprising the implantable medical device.

18. The kit of claim 17, wherein the implantable medical device is a stent.

19. The kit of claim 16, further comprising a viewing device attachable to the base member.

20. The kit of claim 19, wherein the viewing device is an endoscope.

21. The kit of claim 16, wherein the catheter further comprises a trackability zone located between the flexibility zone and the pushability zone, wherein the trackability zone is coated with or comprises an embedded radio-opaque substance.

22. The kit of claim 21, wherein the trackability zone located has a flexibility index of less than 4500 mN.

23. The kit of claim 16, wherein the stabilization zone of the catheter is coated with or comprises an embedded radio-opaque substance.

24. The kit of claim 16, wherein the protection zone of the catheter is coated with or comprises an embedded radio-opaque substance.

25. The kit of claim 16, wherein the flexibility zone of the catheter is coated with or comprises an embedded radio-opaque substance.

26. The kit of claim 16, wherein the pushability zone of the catheter is coated with or comprises an embedded radio-opaque substance.

27. The kit of claim 16, wherein the catheter further comprises a transition area resided between two adjacent zones of different flexibility, wherein the transition area has a flexibility that is intermediate between the flexibilities of the two zones.

28. The kit of claim 16, wherein the protection zone of the catheter comprises an inflatable balloon for deploying the implantable medical device.

29. The kit of claim 16, wherein the stabilization zone and the protection zone of the catheter have a flexibility index of less than 3000 mN.

30. The kit of claim 16, wherein the flexibility zone of the catheter has a flexibility index of less than 3500 mN.

31. The kit of claim 16, wherein the pushability zone of the catheter has a flexibility index of less than 6000 mN.

32. The kit of claim 16, wherein the stabilization zone and the protection zone of the catheter have a flexibility index of less than 3000 mN, the flexibility zone of the catheter has a flexibility index of less than 3500 mN and the pushability zone of the catheter has a flexibility index of less than 6000 mN.
