Abstract
The present embodiments provide prosthesis deployment systems. In one embodiment, a sleeve has proximal and distal regions and a lumen extending therebetween, and further comprising a first exit aperture, a first entrance aperture, and a second exit aperture. A trigger wire is disposed at least partially within the lumen of the sleeve. A prosthesis has a delivery state and an expanded state, and further has first and second regions. In the delivery state, the trigger wire extends out of the lumen through the first exit aperture of the sleeve, restrains the first region of the prosthesis, reenters the lumen through the first entrance aperture of the sleeve, extends out of the lumen through the second exit aperture of the sleeve, and restrains the second region of the prosthesis.
Claims16
A prosthesis deployment system comprising:
- a sleeve having proximal and distal regions and a lumen extending therebetween, and further comprising a first exit aperture, a first entrance aperture, and a second exit aperture;
- a trigger wire disposed at least partially within the lumen of the sleeve;
- and
- a prosthesis having a delivery state and an expanded state, and further having first and second regions,
- where, in the delivery state, the trigger wire extends out of the lumen through the first exit aperture of the sleeve, restrains the first region of the prosthesis, reenters the lumen through the first entrance aperture of the sleeve, extends out of the lumen through the second exit aperture of the sleeve, and restrains the second region of the prosthesis;
- and wherein the prosthesis comprises a stent and a graft.
A prosthesis deployment system comprising:
- a sleeve having proximal and distal regions and a lumen extending therebetween;
- a trigger wire disposed at least partially within the lumen of the sleeve;
- and
- a prosthesis having a delivery state and an expanded state,
- where, in the delivery state, the trigger wire extends both axially and circumferentially within the lumen of the sleeve and restrains at least two regions of the the prosthesis;
- wherein the sleeve further comprises a first exit aperture, a first entrance aperture, and a second exit aperture and where, in the delivery state, the trigger wire extends out of the lumen through the first exit aperture of the sleeve, restrains a first region of the prosthesis, reenters the lumen through the first entrance aperture of the sleeve, extends out of the lumen through the second exit aperture of the sleeve, and restrains a second region of the prosthesis;
- and wherein the prosthesis comprises a stent and a graft.
A prosthesis deployment system comprising:
- a sleeve having proximal and distal regions and a lumen extending therebetween;
- a trigger wire disposed at least partially within the lumen of the sleeve;
- and
- a prosthesis having a delivery state and an expanded state,
- where, in the delivery state, the trigger wire extends both axially and circumferentially within the lumen of the sleeve and restrains at least two regions of the prosthesis, and
- wherein the prosthesis comprises a stent and a graft, and where, in the delivery state, the trigger wire engages a first region of the at least one stent after extending out of the lumen through a first exit aperture of the sleeve and before reentering the lumen through a first entrance aperture of the sleeve.
