System for delivering a stent
First Claim
Patent Images
1. A stent delivery system comprising:
- a hypotube having a proximal end, a distal end and a first diameter;
a guidewire extending beyond a distal end of the hypotube and having a first portion and a second portion, the first portion having a second diameter, the second diameter of the guidewire being less than the first diameter of the hypotube, the guidewire including a second portion having a third diameter, the third diameter being less than the second diameter and forming a reduced diameter portion for receiving a stent;
a sheath covering at least a portion of the reduced diameter portion of the guidewire; and
a control member operatively connected to the sheath, the control member being operable to slide the sheath relative to the stent to expose the stent enabling the stent to move to an expanded configuration.

Abstract
A stent delivery system comprising a hypotube, a guidewire extending beyond a distal end of the hypotube and having a first portion and a second portion. The first portion has a second diameter less than the diameter of the hypotube. The second portion of the guidewire has a third diameter less than the second diameter and forming a reduced diameter portion for receiving a stent. A sheath covers at least a portion of the reduced diameter portion of the guidewire.

17. A stent delivery system comprising:
-
a hypotube having a proximal end, a distal end and a first opening, the hypotube having a reduced diameter portion;
a balloon mounted on the reduced diameter portion of the hypotube and communicating with the first opening;
a valve;
a control member extending within the hypotube, the control member moving the valve from a first position to a second position to block the opening to maintain balloon inflation. - View Dependent Claims (18, 19)
