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.
Claims19
A system for delivering an implant comprising:
- a catheter having a distal end and a proximal end, said proximal end connected to a handle;
- an implant disposed in said distal end of said catheter;
- a wire having a distal end and a proximal end, said distal end including a recess defining a hook portion, said proximal end operably coupled to a slide associated with said handle;
- a sheath surrounding said wire, said sheath having a distal end and a proximal end, said distal end including a mouth, said proximal end attached to a housing, said housing slidingly containing said slide, wherein said wire slides longitudinally within said sheath;
- wherein said slide is movable between a distal position and a proximal position, in said distal position, said wire is advanced distally within said sheath to an open position and in said proximal position, said wire is retracted proximally within said sheath to a closed position;
- wherein said recess is sized to receive a component of said implant;
- wherein said mouth has a slot shaped such that in said closed position, said recess and said slot combine to form a closed transverse passage in which said component is trapped;
- wherein in said open position, said hook portion extends distally from said mouth such that said implant is released from said recess.

A delivery device for percutaneously delivering an implant to a target location comprising:
- a delivery catheter having a distal end and a proximal end, said proximal end connected to a handle;
- a control cable mechanism disposed within said delivery catheter, said control cable mechanism including:
- a wire having a distal end and a proximal end;
- a sheath surrounding said wire, said sheath having a distal end forming a mouth with a slot and a proximal end;
- wherein said distal end of said wire and said sheath form a release mechanism having an open position and a closed position, wherein in said closed position, said slot and said wire combine to form a distally-closed transverse passage and wherein a component of an implant is trapped therein, and in said open position, said implant component is released, said open and closed positions determined by relative positions of said wire within said sheath;
- and
- a controller connected to said proximal end of said wire and said sheath such that said controller moves said wire relative to said sheath between said open position and said closed position.
4 more elements
A method of delivering an implant comprising:
- attaching an implant to a release mechanism having:
- a wire;
- a sheath surrounding said wire, said sheath having a distal end forming a mouth with a slot and a proximal end;
- wherein said distal end of said wire and said sheath form a release mechanism having an open position and a closed position, wherein in said closed position, said slot and said wire combine to form a distally-closed transverse passage and wherein a component of an implant is trapped therein, and in said open position, said implant component is released, said open and closed positions determined by relative positions of said wire within said sheath;
- loading said implant into a distal end of a catheter containing said release mechanism;
- navigating said distal end of said catheter to a target location;
- deploying said implant out of said distal end of said catheter;
- placing said release mechanism in said open position, thereby releasing said implant.
