Abstract

A delivery system used for vascular implant delivery is described. In some embodiments, the delivery system includes a user-gripped handle used to aid in retracting and advancing an implant. In some embodiments, the delivery system includes a telescoping pusher system to aid in retracting and advancing an implant.

Claims (37)

1 . An implant delivery device, comprising:

a handle having an internal track with a bend;

a delivery element having a distal portion distal to the handle and a proximal portion within the handle positioned on or within the internal track;

a user-actuated control mechanism engaged with the delivery element, wherein actuation of the user-actuated control mechanism advances or retracts the proximal portion of the delivery element around the bend of the internal track.

2 . The implant delivery device of claim 1 , wherein the user-actuated control mechanism is a sliding mechanism.

3 . The implant delivery device of claim 1 , wherein the user-actuated control mechanism is a rotational mechanism.

4 . The implant delivery device of claim 1 , wherein advancing the delivery element deploys an implant.

5 . The implant delivery device of claim 4 , wherein the delivery element is a pusher.

6 . The implant delivery device of claim 1 , wherein retracting the delivery element deploys an implant.

7 . The implant delivery device of claim 6 , wherein the delivery element is a delivery sheath or catheter.

8 . The implant delivery device of claim 1 , wherein the internal track includes one or more mechanical rollers.

9 . The implant delivery device of claim 8 , wherein actuation of the user-actuated control mechanism engages the one or more mechanical rollers.

10 . The implant delivery device of claim 1 , wherein the internal track includes a recess.

11 . The implant delivery device of claim 1 , wherein the internal track has a U shape or a serpentine shape.

12 . The implant delivery device of claim 1 , wherein retracting or advancing the distal portion of the delivery device causes the proximal portion to move in a direction opposite of the distal portion.

13 . The implant delivery device of claim 1 , wherein the entire delivery element is distal to a proximal end of the handle.

14 . The implant delivery device of claim 13 , wherein the handle has a first longitudinal length and actuation of the user-actuated control mechanism advances or retracts the proximal portion of the delivery element a distance having a second length, and

wherein the second length is greater than the first length.

15 . An implant delivery device, comprising:

a handle;

a delivery element having a distal portion distal to the handle and a proximal portion within the handle;

a user-moveable control mechanism engaged with the delivery element,

where in a first configuration, the distal portion of the delivery element is in a first position and the proximal portion of the delivery element is in a second position,

where in a second configuration, the distal portion of the delivery element is in a third position proximal to the first position, and the proximal portion of the delivery element is in a fourth position distal to the second position.

16 . The implant delivery device of claim 15 , wherein the handle further comprises an internal track with a bend, and

wherein the proximal portion of the delivery element is positioned on or within the internal track.

17 . The implant delivery device of claim 16 , wherein the internal track is a guide for the proximal portion of the delivery element between the first and second configurations.

18 . An implant delivery device, comprising:

a handle having a first longitudinal length;

a delivery element having a distal portion distal to the handle and a proximal end within the handle;

a user-actuated control mechanism engaged with the delivery element, wherein actuation of the user-actuated control mechanism advances or retracts the proximal end of the delivery element a distance having second length, and

wherein the second length is greater than the first longitudinal length.

19 . The implant delivery device of claim 18 ,

wherein actuation of the user-actuated control mechanism retracts the proximal end of the delivery element along an internal track having one or more bends,

wherein the internal track has a third length greater than the first longitudinal length of the handle.

20 . The implant delivery device of claim 19 , further comprising an implant pre-loaded within the delivery element,

where in a compressed configuration, the implant has a fourth longitudinal length greater than the first longitudinal length of the handle.
