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 ina 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.; A flexible low profile delivery system (10) for delivery of an expandable intracorporeal device (11), specifically, an endovascular graft, which has at least one belt (21) circumferentially disposed about the device in a constraining configuration. The belt (21) is released by a release member (24), such as a release wire, by retracting the wire from looped ends (81) of the belt (21). Multiple belts (24, 21, 22) can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft (11). An outer protective sheath (53) may be disposed about the endovascular (11) graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft (11) from a constrained state. The delivery system (10) can be configured for delivery over a guiding device (18) such as a guidewire.; The delivery system can also be configured for delivery of bifurcated intracorporeal devices. |
