Abstract
A stent delivery assembly can include a stent, a tube, a shaft slidably disposed within the tube, and an engagement member on the shaft. The engagement member is operable via the shaft so as to facilitate manipulation of the stent via the shaft. The engagement member can engage the stent inner wall and cooperating with the tube to grip the stent. The shaft is arranged within the tube with a close tolerance between the shaft and the tube so as to provide stability during retraction or advancement of the shaft.
Claims10
A method of advancing an everted tubular braid to a target region, the method comprising the steps of:
- providing a medical device comprising a delivery member and a braided tubular member coupled to the delivery member, the tubular member having a first portion and a second portion;
- while maintaining the tubular member in a first configuration in which the first portion is positioned proximal of the second portion and the second portion is everted into the first portion, advancing the tubular member through a lumen of a catheter toward the target region, the catheter having a distal end, the catheter constraining the tubular member from radially expanding;
- advancing the tubular member, in the first configuration, beyond the catheter distal end;
- and
- permitting the tubular member to move to a second configuration in which the tubular member second portion is in a non-everted position, distal to the first portion.
