Abstract: A modular intraluminal stent graft. The intraluminal stent graft is bifurcated having a primary section and a secondary section extending therefrom. The primary section tapers from a larger diameter at an upstream end to a smaller diameter at a downstream end. The downstream end of the primary section has a pair of independent openings each having an expanded diameter. The secondary section provides a first endoleg having an upstream end that is received through the expanded diameter of one opening of the primary section, and a second endoleg having an upstream end that is received through the second opening of the primary section. The upstream ends of each endoleg, in its expanded state, is larger than the downstream portion of the respective endolegs and expands within the primary section to help assemble the graft in situ. The first and second endolegs also expand within the respective openings each is received within to assemble the stent graft in situ as well.

Abstract: The present disclosure is directed to a device for housing and retaining a delivery system for a self-expanding implant while providing means for actuating the delivery system.

Abstract: The present invention relates to a delivery system for an intraluminal thin film medical device particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The delivery system has an outer sheath attached along the distal end of a relatively long and flexible tubular shaft. The outer sheath is capable of constraining the thin film medical device in a longitudinally stretched position, and subsequently being retracted relative to the flexible tubular shaft to release the thin film medical device from the constrained longitudinally stretched position. The delivery system may additionally have a secondary sheath substantially coaxial too, and slideably engaged within, the outer sheath. The secondary sheath is capable of restraining a self-expanding support structure in a radially constrained position, and subsequently being retracted to release the self-expanding support structure from the radially constrained position.

Abstract: The present invention relates to an intraluminal thin film medical device particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The medical device has a thin film tube capable of being longitudinally stretched by the application of mechanical energy to achieve a smaller circumferential profile, and self-expand to the pre-stretched length and diameter upon release of the mechanical energy. To assist the thin film during expansion a plurality of slots are incised in the tube wall. The slots open and assist the thin film tube to longitudinally stretch, and substantially close when the thin film tube self-expands to the pre-stretched length and diameter.

Abstract: An abdominal aortic aneurysm endoprosthesis having a reduced profile for percutaneous delivery of the endoprosthesis. The endoprosthesis provides a cranial section supported by a stent, and a bifurcated caudal section having at least two legs each of which are supported by individual stents. The individual stents of each leg of the caudal section are staggered so as not to line up with one another. Altering the lengths of the legs permits nesting of the endoprosthesis. Optimizing the expansion ratio and radial strength of the endoprosthesis is achieved by altering the dimensions of the starting material from which the stent segments are fabricated, by altering the final austentite temperature of the starting materials, or by changing the structural configuration of the stent segments. A graft material is attached to at least a portion of the cranial section and to all of the caudal section of the endoprosthesis.

Abstract: An endoprosthesis for repairing and treating abdominal aortic aneurysms. The endoprosthesis features an anchoring and sealing component and low profile bifurcated legs. A biocompatible graft material is secured to at least the bifurcated legs in order to provide two endoleg fluid flow lumens or conduits. The bifurcated legs have staggered stent elements that nest to contribute to the low profile nature of the device and additional longitudinal struts between pair of the staggered stent elements to increase the longitudinal stiffness of the bifurcated legs while maintaining the patency of the lumen created thereby.

Abstract: A system for delivering at least one medical device to a desired location for treatment, and then selectively deploy it in position, includes an improved handle. One of the possible features of the handle may be to selectively hold the delivery system components at any desired configuration during deployment and positioning of the medical device. Another possible feature of the handle may be more than one mode of operation, in which the deployment of the medical device can selectively proceed at more than one speed.

Abstract: A delivery apparatus for a self-expanding stent is disclosed. The apparatus has an outer sheath forming an elongated tubular member having distal and proximal ends and an inside and outside diameter. The apparatus also includes an inner shaft located coaxially within the outer sheath. The inner shaft has a distal end, a proximal end and longitudinal axis extending therebetween. At least a portion of the inner shaft is made from a flexible coiled member. The shaft preferably includes a stop attached thereto, the stop being proximal to the distal end of the sheath. Lastly, the apparatus includes a self-expanding stent located within the outer sheath, wherein the stent makes frictional contact with the outer sheath and the shaft is disposed coaxially within a lumen of the stent. During deployment of the stent, the stent makes contact with the stop.
