Inversion delivery device and method for a prosthesis
First Claim
Patent Images
1. A delivery device for a medical implant comprising:
- a handle;
a catheter extending from a distal end of said handle, said catheter including a delivery catheter and a pusher catheter slidingly disposed within said delivery catheter, wherein said delivery catheter is fixed relative to said distal end of said handle and said pusher catheter has a plurality of lumens;
a pusher catheter control moveably attached to said handle and operably coupled to said pusher catheter such that axial movement of said pusher catheter control relative to said handle causes said pusher catheter to move axially within said delivery catheter, wherein said pusher catheter control is operably coupled to said pusher catheter through a slot in said handle.

Abstract
A delivery device usable to deliver an inverting implant is provided that includes a positioning mechanism that automatically initiates the inversion process once a predetermined length of the implant has exited a delivery catheter. The positioning mechanism allows the implant to be safely and accurately deployed with reduced operator experience and in a greater variety of target locations.

7. A method of delivering an implant to a target location comprising:
-
advancing a delivery catheter through a vasculature to a target location, said delivery catheter connected to a handle, said delivery catheter containing a pusher catheter slidably disposed therein and an implant; unsheathing said implant from said delivery catheter by retracting said delivery catheter relative to said pusher catheter, which is accomplished by holding said handle with a first hand while rotating a delivery catheter drive mechanism with a second hand; retracting said pusher catheter by sliding a control in a proximal direction on an outside surface of said handle. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A pusher catheter for a delivery device having a handle comprising:
-
at least one lumen; at least one longitudinal groove on an outside surface of said pusher catheter, and extending at least from said handle to a distal end of the pusher catheter, said groove forming a passage for a control wire when said pusher catheter is placed within a delivery catheter; a control distal of a proximal end of said pusher catheter, said control arranged on an outside surface of, and extending through said handle, thereby allowing a user to advance or retract said pusher catheter within a delivery catheter. - View Dependent Claims (15, 16)
