A stent graft delivery system includes a handle, a guidewire catheter extending distally from the handle, at least one tube, and at least one wire extending through the at least one tube, wherein each wire of the stent graft delivery system is configured as a loop at the distal end of the tube. The stent graft delivery system can be employed to implant stent grafts in a patient to thereby treat, for example, an aortic aneurysm spanning a region of an aorta that includes at least one arterial branch.

A stent-graft has a closed web end configuration in which endmost stent crowns do not extend beyond an end or edge of a tubular graft. In order to couple the stent-graft to tip capture fingers or prongs of a delivery system, the stent-graft includes a ring woven between the endmost crowns of an end stent. When end stent is in a compressed delivery configuration, sections of the ring between adjacent endmost crowns form attachment loops that longitudinally extend beyond the end of the tubular graft for engaging the tip capture fingers of a delivery system. When the end stent is in an expanded fully deployed configuration, the attachment loops retract back to the stent so that the ring is a circular band having a diameter substantially equal to the expanded diameter of the stent.

A prosthesis delivery device comprises a proximal end and a distal end, a prosthesis retention section at the proximal end, and a prosthesis retained on the prosthesis retention section. The prosthesis has a proximal end releasably attached at the prosthesis retention section and a distal end releasably attached at the prosthesis retention section. A sheath is slidably disposed over the prosthesis. A delivery handle near the distal end the delivery device comprises a rotatable inner cannula having a cannula lumen and cannula handle. The cannula handle is rotatable with the inner cannula. Further, a positioner handle is releasably engaged with the cannula handle. Rotation of the inner cannula releases the proximal end of the prosthesis from the delivery device and withdrawal of the sheath from over the prosthesis releases the distal end of the prosthesis from the delivery device.

A system and method for deploying an occluding device that can be used to remodel an aneurysm within the vessel by, for example, neck reconstruction or balloon remodeling. The system comprises an introducer sheath and an assembly for carrying the occluding device. The assembly includes an elongated flexible member having an occluding device retaining member for receiving a first end of the occluding device, a proximally positioned retaining member for engaging a second end of the occluding device and a support surrounding a portion of the elongated flexible member over which the occluding device can be positioned.

This document describes devices for treating atherosclerosis and methods for their use. For example, this document describes stent graft devices that include a fenestration or end scallop that is advantageous for use at a bifurcation of a vessel. Specifically, a medical device with a catheter comprising an elongate shaft with a proximal balloon member at a distal end, a distal balloon at the distal end spaced apart from the proximal balloon and a lateral opening in the shaft between the proximal and distal balloon members. The device also comprises a stent graft constructed of a wire framework and cover material, and a fenestration defined through the framework. The stent graft is disposed on the proximal and distal balloon members.

A stent-graft prosthesis includes a graft material having a tubular construction, a frame coupled to the graft material, and a port or opening disposed between a proximal end and a distal end of the graft material. The port or opening is open during deployment of the stent-graft prosthesis to enable blood flow from a graft lumen within the graft material to exit the graft lumen, and the port or opening is blocked upon full deployment of the stent-graft prosthesis to prevent blood flow from within the graft lumen from exiting the graft lumen through the port or opening.

A stent delivery system is provided that includes an inner elongate shaft with a lumen and an outer elongate shaft with a lumen, where the inner elongate shaft coaxially extends at least partially within the lumen of the outer elongate shaft. The stent delivery system also a pull member movably disposed along the the inner elongate shaft and first and second restraining members removably secured to the pull member. The stent delivery system also includes a self-expanding stent having an expanded configuration and a collapsed configuration, where the first restraining member is secured to a first portion of the self-expanding stent and the second restraining member is secured to a second portion of the self-expanding stent, thereby securing the self-expanding stent about the outer elongate shaft. Movement of the inner and elongate shafts relative to each other in a first direction applies a tension to the first and second restraining members to move the self-expanding stent to the collapsed configuration.

Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.

A trans-aortic proximal aortic stent graft [TAPAS graft] (7) for introducing into a blood vessel. A a tubular sheath which encases a folded self-expanding prosthesis (4) from the inside as well as from the outside such that a sheath outer wall (2) of the sheath lies against the prosthesis (4) from the outside and a sheath inner wall (3) lies against the prosthesis from the inside and keeps the prosthesis (4) folded. The prosthesis (4) is surrounded by the sheath at the distal end in the transition from the sheath inner wall (3) to the sheath outer wall (4), and the prosthesis (4) is provided with an anchor (8) at the proximal end. Also, a method for using a trans-aortic proximal aortic stent graft [TAPAS graft] (7).
