DELIVERY SYSTEM FOR TRANSCATHETER DETACHMENT OF A STENT FROM THE DELIVERY DEVICE

摘要

Described is an apparatus for transcatheter detachment of a stent from a delivery device. A braided suture with an opening is inserted through a restraining hole in a glide (the opening is secured on one side by a knot or a series of knots) and a release line is inserted through the braided suture opening. The braided suture is thus prevented from pulling through the restraining hole while the release line is through the opening. The braided suture is free to pass through the restraining hole after the release line is pulled out of the opening and thereafter pulled free of stent holes formed through a stent, thereby detaching the stent at a desired location.

主权项

1. A delivery system for transcatheter delivery and detachment of a stent, comprising:
a glide, the glide having a plurality of restraining holes therethrough; a plurality of draw lines, each draw line having an opening formed therethrough, and wherein each draw line is adapted to pass through a stent hole in a stent and thereafter through a restraining hole in the glide; and a release line having a distal end and a proximal end, the distal end of the release line being adapted to pass through the openings of the draw lines and affix a stent with the glide, whereby upon implantation, a user can pull on the proximal end of the release line, which pulls the release line from the draw lines to allow the draw lines to be drawn from the stent, thereby detaching the stent at a desired location.
