Abstract

A medical implant deployment tool and deployment method are disclosed. One aspect of the invention provides an implant system including an implant adapted for endovascular delivery and deployment; and a deployment tool adapted to deploy the implant, with the deployment tool having an actuation controller; a plurality of actuation elements adapted to apply forces to one or more implant deployment mechanisms and each adapted to extend along an actuation element path within a patient'"'"'s vasculature; and an actuation element compensation mechanism adapted to compensate for differences in length between the actuation element paths.

Claims

1. (copied from claim 1 of US 2007/0055340) A catheter system for treating a vascular condition, comprising:

a catheter;

a catheter center member;

a catheter sheath having a plurality of pullwire lumens evenly spaced about a central axis of the catheter;

a plurality of pullwires received within the pullwire lumens; and

a pivoting connector operably attached to proximal portions of the pullwires;

a pull member connected to said pivoting connector which is fixed to said center member to facilitate relative motion between said center member and said pivoting connection.

2. (copied from claim 2 of US 2007/0055340) The system of claim 1 wherein the connector is a wheel having at least one groove formed in an outer surface of the wheel.

3. (copied from claim 3 of US 2007/0055340) The system of claim 1 wherein the connector is a narrow, elongated member.

4. (copied from claim 4 of US 2007/0055340) The system of claim 1 wherein the connector is a substantially flat, triangular plate.

5. (copied from claim 5 of US 2007/0055340) The system of claim 1 wherein the connector is a hemisphere.

6. (copied from claim 6 of US 2007/0055340) The system of claim 1 further comprising:

a master pullwire operably attached to the connector.

7. (copied from claim 7 of US 2007/0055340) The system of claim 1 wherein the catheter includes a central guidewire lumen.

8. (copied from claim 8 of US 2007/0055340) The system of claim 7 further comprising:

a guidewire.

9. (copied from claim 9 of US 2007/0055340) The system of claim 1 further comprising:

a flexible conduit enclosing a proximal portion of each pullwire.

10. (copied from claim 10 of US 2007/0055340) A stent delivery system, comprising:

a catheter having a plurality of pullwire lumens evenly spaced about a central axis of the catheter;

a stent mounted on a distal portion of the catheter;

a retractable sheath enclosing the stent; and

a plurality of pullwires received within the pullwire lumens, the pullwires attached to the retractable sheath.

11. (copied from claim 11 of US 2007/0055340) The system of claim 10 further comprising:

a pivoting connector operably attached to proximal portions of the pullwires.

12. (copied from claim 12 of US 2007/0055340) The system of claim 11 further comprising:

a master pullwire operably attached to the connector.

13. (copied from claim 13 of US 2007/0055340) The system of claim 10 wherein the pullwires are attached to a mid-portion of the retractable sheath.

14. (copied from claim 14 of US 2007/0055340) The system of claim 10 wherein the catheter includes a central guidewire lumen.

15. (copied from claim 15 of US 2007/0055340) The system of claim 14 further comprising:

a guidewire.

16. (copied from claim 16 of US 2007/0055340) A stent delivery system, comprising:

an inner member;

a stent mounted on the inner member;

a catheter enclosing at least a portion of the stent, the catheter including a plurality of pullwire lumens evenly spaced about a central axis of the catheter; and

a plurality of pullwires received within the pullwire lumens.

17. (copied from claim 17 of US 2007/0055340) The system of claim 16 further comprising:

a pivoting connector operably attached to proximal portions of the pullwires.

18. (copied from claim 18 of US 2007/0055340) The system of claim 17 further comprising:

a master pullwire operably attached to the connector.

19. (copied from claim 19 of US 2007/0055340) The system of claim 16 further comprising:

a retractable sheath enclosing a distal portion of the stent, wherein distal portions of the pullwires are attached to the retractable sheath.

20. (copied from claim 20 of US 2007/0055340) The system of claim 19 wherein the retractable sheath encloses a distal portion of the catheter.

21. (copied from claim 21 of US 2007/0055340) The system of claim 16 wherein the inner member includes a central guidewire lumen.

22. (copied from claim 22 of US 2007/0055340) The system of claim 21 further comprising:

a guidewire.
