1. A control cable mechanism for use with an implant delivery system comprising:
- 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;
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 a medical 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 an implant is released from said recess.

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.

10. 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 plurality of control cable mechanisms disposed within said delivery catheter, each of said control cable mechanisms 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 ends 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 ends 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
