Delivery system and method for bifurcated graft
First Claim
1. A delivery system for a bifurcated intracorporeal device comprising:
- an elongate shaft having a proximal section and a distal section with the distal section comprising;
an elongate primary belt support member positioned to be disposed within at least a portion of the bifurcated intracorporeal device;
at least one primary belt secured to the primary belt support member configured to be circumferentially disposed about a bifurcated intracorporeal device so to at least partially constrain the device;
a primary release member configured to engage and releasably secure the primary belt in a constraining configuration;
at least one elongate secondary belt support member disposed adjacent the elongate primary belt support member;
at least one secondary belt secured to the secondary belt support member configured to be circumferentially disposed about a bifurcated intracorporeal device so to at least partially constrain the device; and
a secondary release member configured to engage and releasably secure the secondary belt in a constraining configuration.

Abstract
A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices.

15. A delivery system for a bifurcated graft comprising:
an elongate shaft having a proximal section and a distal section with the distal section comprising;
a portion having disposed thereon the bifurcated graft, the graft having a main body portion, an ipsilateral leg and a contralateral leg;
an elongate primary belt support member disposed within the main body portion and ipsilateral leg;
at least one primary belt secured to the primary belt support member and circumferentially disposed about the bifurcated graft and which constrains at least a portion of the graft;
a primary release member which releasably secures the primary belt in the constraining configuration;
at least one secondary belt support member disposed adjacent the contralateral leg;
at least one secondary belt secured to the secondary belt support member and circumferentially disposed about the bifurcated graft and which constrains at least a portion of the graft; and
a secondary release member which releasably secures the secondary belt in the constraining configuration. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
