Apparatus and methods for delivery of intraluminal prostheses
First Claim
1. A device for delivery of an intraluminal prosthesis, comprising:
- an elongated flexible sleeve having a proximal end and a distal area with a distal end;
an outer shaft having a proximal end and a distal area with a distal end, said outer shaft disposed within said sleeve and movable relative to said sleeve;
a securing member disposed on said outer shaft;
an inner shaft with a proximal end and a distal end, said inner shaft disposed within said outer shaft and movable relative to said outer shaft; and
an atraumatic tip disposed at said distal end of said inner shaft, wherein said prosthesis is housed within said sleeve and said prosthesis is secured to said outer shaft by said securing member.

Abstract
An apparatus and method for intraluminal delivery and deployment of an expandable prosthesis at a site within a body canal is provided. The apparatus comprises an elongated sleeve and an outer shaft disposed within the elongated sleeve and movable relative to the sleeve. A securing member is disposed on a distal area of the outer shaft. The expandable prosthesis is housed within a distal area of the elongated sleeve, and a distal area of the prosthesis is secured to the outer shaft by the securing member. The stent is deployed by displacing the sleeve in a proximal direction relative to the outer shaft to expose the stent and by releasing the stent from the securing member. If necessary, the stent can be repositioned prior to releasing the stent from the securing member.

wherein said prosthesis is in a contracted condition within said distal area of said sleeve, whereby relative longitudinal motion between said sleeve and said outer shaft exposes said prosthesis and allows the exposed portion of said prosthesis to radially expand, and wherein said sleeve is slidingly movable in a proximal direction relative to said outer shaft to expose said prosthesis, and wherein said prosthesis remains secured to said outer shaft by said securing member when said prosthesis is filly exposed, and wherein relative longitudinal motion between said outer shaft and said inner shaft releases said securing member from said prosthesis. -
3. The device according to claim 2, wherein said hand piece further comprises a tube connected to said sleeve and said lever so that actuation of said lever drives said tube in a proximal direction, and wherein movement of said tube causes said sleeve to be driven in a proximal direction.
-
4. The device according to claim 3, wherein said tube is biased in a distal direction by a spring.
-
5. The device according to claim 2, wherein said hand piece further comprises a release member coupled to said outer shaft, wherein said release member drives said outer shaft in a proximal direction relative to said inner shaft and releases said securing member from said prosthesis.
-
6. The device according to claim 5, wherein said inner shaft is fixedly connected to said hand piece.
-
7. The device according to claim 6, wherein said introducer includes a stop-cock for delivery of at least an aliquot of liquid solution from the group consisting of a contrast medium, saline, lactated ringer, dextran solution, antibacterial, or angiogenic growth factors.
-
8. The device according to claim 2, further comprising a port at a proximal end of said hand piece for delivery of at least an aliquot of liquid solution from the group consisting of a contrast medium, saline, lactated ringer, dextran solution, antibacterial, or angiogenic growth factors.
