Abstract:
A stent and stent delivery catheter assembly, comprising:an elongated catheter having a proximal end and a distal end, an expandable member for expanding a stent and a passageway for slidably receiving a guide wire therein, the passageway extending between a first port in the distal end of the catheter and a second port spaced a relatively short distance proximally from the distal end of the catheter and a relatively long distance from the proximal end of the catheter; an expandable stent being mounted on the expandable member and being expandable from a first diameter as mounted on the expandable member to a second implanted diameter wherein the stent is implanted in a vessel; a ramp positioned in the guide wire passageway adjacent the second port to guide a proximal end of the guide wire out of the second port when the catheter is mounted onto the guide wire; an elongated sheath having a passageway for receiving the elongated catheter; and wherein the elongated sheath includes a distal port at a distal end of the sheath and a proximal guide wire port spaced distally of the proximal end.
