Deployment system for an intraluminal medical device
First Claim
1. An intraluminal medical device delivery system comprising:
- a catheter having an inner member and an outer member, at least one of the inner member and the outer member being movable relative to one another;
a support member provided on the inner member; and
a self-expanding intraluminal medical device crimped over and mechanically compressing the support member until delivery of the stent to an intended treatment site is effected.

Abstract
An intraluminal medical device delivery system that distributes forces more uniformly across an intraluminal medical device during loading and delivery of the device to an intended treatment site. A support member provided on an inner member of a catheter delivery system helps to more uniformly distribute forces across the device by crimping the device over the support member so as to place the support member in a mechanically compressed state during delivery of the device to the intended treatment site. The support member is preferably comprised of a material having a modulus of elasticity that increases when the material is compressed. The mechanical nature of the support member provides increased stability to the device during loading and delivery thereof without providing heat or other preformed or additional mechanical members to the support member. Repositioning of the device is available due to the stability of the device when mounted on the support member. The intraluminal medical device can be a stent, a stent graft, segments thereof, or a series of such stents, stent grafts, or segments thereof.

21. A method of delivering a self-expanding intraluminal medical device to an intended treatment site in a body of a patient, comprising:
-
providing a catheter having an inner member, an outer member, a mechanically compressible support member, the support member located on the inner member and at least one of the inner member and the outer member movable relative to one another;
loading and crimping the self-expanding intraluminal medical device onto the support member so as to mechanically compress the support member;
restraining the intraluminal medical device in its crimped state and the support member in its compressed state within the outer member;
delivering the intraluminal medical device to the intended treatment site by one of pushing the inner member with the support member beyond a distal end of the outer member or withdrawing the outer member while maintaining the inner member with the support member in place relative to the intended treatment site;
resuming an expanded state of the intraluminal medical device at the intended treatment site; and
withdrawing the inner member and the support member. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
