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.
Claims20
A method of acting on an implant during delivery comprising:
- navigating an implant to a target delivery site using a delivery catheter, said implant being releasably connected to said delivery catheter by at least one tether;
- activating a mechanism that alters a linear position of at least a portion of said implant relative to at least a component of said delivery catheter;
- wherein continued activation of said mechanism engages and disengages a component attached to said at least one tether such that said tether experiences tension when said component is engaged and a release of said tension when said component is disengaged;
- and,
- wherein engagement and disengagement of said component is dependent on a position of said mechanism.
2 more elements
A medical implant delivery system comprising:
- an implant;
- a delivery catheter;
- at least one tether within said delivery catheter and having a distal end and a proximal end, said distal end releasably attached to said implant;
- a carriage attached to said proximal end of said at least one tether;
- a handle assembly at a proximal end of said delivery catheter and slidably housing said carriage therein;
- an activation mechanism that changes a linear position of said implant relative to said delivery catheter;
- wherein operation of said activation mechanism automatically engages and disengages said carriage such that said carriage slides within said handle assembly for only a portion of a range of said activation mechanism.
4 more elements
A medical implant delivery system comprising:
- an implant;
- a delivery catheter;
- at least one tether within said delivery catheter and having a distal end and a proximal end, said distal end releasably attached to said implant;
- a pusher catheter slidingly disposed within said delivery catheter;
- an inversion mechanism that selectively associates and disassociates movement of said at least one tether with the relative movement between the delivery catheter and the pusher catheter.
