LUER OR CLAMP-TYPE SUTURE RELEASE APPARATUS AND METHOD FOR LOADING AND DELIVERING A STENT
First Claim
1. An apparatus for delivering a self-expanding stent within a body lumen comprising:
- (a) a delivery catheter for delivering the stent, the delivery catheter comprising;
(i) an elongate flexible shaft;
(ii) an elongate tube adapted to enter the body lumen, the tube moveably disposed over a portion of the shaft, the elongate tube comprising a hollow cylindrical passage for containing the stent in its radially compressed state;
(iii) a handle secured to the proximal end of the flexible shaft, the handle having at least one detent;
(b) a transfer member removeably engagable with a distal end of the delivery catheter, the transfer member comprising a funnel-shaped passage for compressing a stent from an at least partially radially expanded state to an at least partially radially compressed state when the stent is moved through the passage of the transfer member and into the hollow cylindrical passage of the delivery catheter; and
(c) an elongate filament for manipulating the stent through the passage of the transfer member, the elongate filament having two opposed ends and a medial portion disposed between the two opposed ends,wherein the elongate filament passes through a handle passage in at least a portion of the handle and further wherein the medial portion is releasably secured to a proximal end of the stent and the two opposed filament ends are accessible at the at least one detent of the handle.

Abstract
An assembly for delivering a self-expanding stent within a body lumen is includes a self-expanding stent, a delivery catheter for delivering the stent, a transfer member removeably engagable with a distal end of the delivery catheter, and an elongate filament for manipulating the stent through the passage of the transfer member. The delivery catheter includes an elongate flexible shaft having a stent holder at its distal end for restraining axial movement of the stent when the stent is disposed within a hollow cylindrical passage of an elongate tube moveably disposed over a portion of the shaft, and a handle secured to the proximal end of the flexible shaft. The elongate filament is releasably secured to the stent, and the ends of the filament are accessible at the handle to permit movement of the stent within the device by manipulation of the filament.
