A stent graft () has a tubular body () of a biocompatible material and at least one fenestration (). The or each fenestration has a tubular side branch stitched into it with a portion of the tubular side branch extending within the tubular body and a portion of the tubular side branch extending exteriorly of the tubular body. The stitching by which the tubular side branch is mounted into the fenestration extends circumferentially and diagonally from one end of the tubular side branch to the other such that the tubular side branch extends from the tubular body at an angle thereto. The tubular side branch has a resilient ring around at least one and preferably both ends thereof and a self expanding stent in between them. The tubular side branch can have a circumferential linear portion () at an inner end to engage against the inner wall () of the tubular body. The tubular side branch can have a stent made from a single wire forming a first ring (), a second ring (), the second ring defining a plane which is substantially parallel to and spaced axially apart from the plane of the first ring and a number of helical wire portions () extending between the first and second ring. Preferably the wire is a shape memory wire such as Nitinol™ wire.

A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.

A stent graft for use in a medical procedure to treat a dissection of a patient's ascending thoracic aorta. The stent graft includes bare alignment stents at least at a proximal end, and often with a stent at both ends, each stent having opposing sets of curved apices, where the curved section of one broader set of apices has a radius of curvature that is greater than the curved section of the other narrower set of apices. The proximal stent is flared in a manner such that its broad apices occupy a larger circumference around the stent than do its narrower apices, where this flared feature provides for anchoring engagement near the aortic root in a manner not interfering with the coronary arteries or the aortic valve.

An implantable endoluminal prosthesis for replacing a damaged aortic valve is provided. In one embodiment, the prosthesis includes a balloon-expandable stent, a tubular conduit that extends into the ascending aorta, and a self-expanding stent. The tubular conduit extends across the balloon-expandable stent. The tubular conduit includes an artificial valve. The self-expanding stent extends across the tubular conduit into the ascending aorta. The balloon-expandable stent, the tubular conduit, and the self-expanding stent are coupled to provide unidirectional flow of fluid into the aorta and further into the coronary arteries. Also provided is a method for implanting the endoluminal prosthesis.

A stent graft leg extension () to extend from a bifurcated aortic stent graft into an iliac artery. The stent graft has a tubular body. () of a biocompatible graft material and a plurality of self-expanding stents () joined to and supporting the tubular body. An uncovered tubular self-expanding stent assembly () extends from a first end of the tubular body and is fastened thereto. The uncovered tubular self-expanding stent assembly () provides a smooth transition from the leg extension into the iliac artery to reduce the chance of kinks causing problems in the leg extension.

The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.

A stent graft delivery device () has a pull wire arrangement with a pull wire () fastened to the distal end of a nose cone dilator () and extending to a wire pull mechanism () for the pull wire associated with a handle () of the stent graft delivery device. The pull wire can be pulled by the wire pull mechanism to induce a curve in a guide wire catheter () distally of the nose cone dilator such that the proximal end of the delivery device more closely fits the shape of a portion of the vasculature of a patient into which the device is deployed.

A stent graft () has a tubular body () of a biocompatible material and at least two fenestrations (). The at least two fenestrations () are adjacent each other and each has a tube () extending into the tubular body (). The tubes () are joined inside the tubular body () into a single larger tube () to facilitate catheterization.
