摘要： 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.

摘要： 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.

摘要： Apparatus and methods are described including implanting an aortic pressure-loss-reduction device in a subject's ascending aorta. While the device is inside a catheter, a distal end of the catheter is placed within the ascending aorta. A proximal covering sheath of the catheter is retracted such as to uncover at least a portion of a downstream anchor, such that the uncovered portion of the downstream anchor includes a portion of the frame that does not have material coupled thereto. Subsequently, a distal covering sheath of the catheter is advanced, such as to cause an upstream anchor to anchor an upstream end device to the subject's ascending aorta, by the upstream anchor radially expanding against an inner wall of the ascending aorta. Other applications are also described.

摘要： 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.

摘要： An elongate delivery shaft assembly (30) includes an outer covering shaft (38) and an inner support shaft (40). When the delivery shaft assembly (30) is unconstrained and a stent-graft (20) is removably constrained in a radially-compressed delivery state along a distal end portion (34) of the delivery shaft assembly (30), radially between the outer covering shaft (38) and the inner support shaft (40): (a) the delivery shaft assembly (30) is shaped so as to define a self-orienting portion (50), which (i) is shaped so as to define at least proximal and distal curved portions (52A, 52B), the proximal curved portion (52A) disposed more proximal than the distal curved portion (52B), and (ii) at least one point of inflection (53) on a central longitudinal axis (36) of the delivery shaft assembly (30) longitudinally between the proximal and the distal curved portions (52A, 52B), and (b) respective smallest radii of curvature of the proximal and the distal curved portions (52A, 52B), measured at the central longitudinal axis (36), are each between 2.5 and 12 cm.

摘要： Apparatus and methods are described including implanting an aortic pressure-loss-reduction device in a subject's ascending aorta. A frame of the device includes a first set of sinusoidal struts disposed between a downstream end of an upstream anchor and an upstream end of the intermediate portion, the sinusoidal struts being shaped to form a folded portion between the downstream end of the upstream anchor and the upstream end of the intermediate portion. The frame includes a second set of sinusoidal struts disposed between an upstream end of a downstream anchor and a downstream end of the intermediate portion, the sinusoidal struts being shaped to form a folded portion between the upstream end of the downstream anchor and the downstream end of the intermediate portion. Other applications are also described.
