    摘要: A stent graft leg extension (10) to extend from a bifurcated aortic stent graft into an iliac artery. The stent graft has a tubular body. (12) of a biocompatible graft material and a plurality of self-expanding stents (14) joined to and supporting the tubular body. An uncovered tubular self-expanding stent assembly (26) extends from a first end of the tubular body and is fastened thereto. The uncovered tubular self-expanding stent assembly (26) provides a smooth transition from the leg extension into the iliac artery to reduce the chance of kinks causing problems in the leg extension.

    摘要: An apparatus for renal neuromodulation includes an expandable support member having a main body portion for engaging a wall of a blood vessel proximate a renal vasculature and at least one electrode connected with the main body portion. The at least one electrode is arranged to selectively deliver electric current to a desired location where modulation of the sympathetic nervous system is effective to alter renal function. The apparatus further includes an insulative material attached to at least a portion of the main body portion for isolating blood flow through the vessel from the electric current delivered by the at least one electrode.

    摘要: A modular stent graft assembly (10) for repairing a ruptured abdominal aorta aneurysm (90) and having an aortic section tubular graft (12) and an iliac section tubular graft (14). The aortic section graft has a proximal attachment stent (32) thereon for suprarenal attachment of the assembly (10) to the aorta. A proximal end portion (50) of the iliac section graft (14) underlies the distal end portion (28) of the aortic graft (12) and presses outwardly thereagainst forming a a friction fit, at a telescoping region (64). The assembly (10) can be selected from an inventory (300) containing a set of delivery systems (100) of four size aortic section grafts (12) and a set of delivery systems (200) of four size iliac section grafts (14), that together accommodate a large majority of aneurysm sizes, and delivery systems (250) containing four standard sizes of occluders (80).

    摘要: A stent graft delivery system in which a stent graft (6) is retained on a delivery device (2) such that a longitudinal portion of the stent graft is releasably retained on the delivery device to bend therewith. The delivery device (2) has a guide wire catheter (3) and the stent graft is retained onto the guide wire catheter by a release wire (24) which can be withdrawn. The release wire is wound around the guide wire catheter and through the stent graft or suture loops engage around the guide wire catheter and release wire.

    摘要: A method is provided for renal neuromodulation. One step of the method includes providing an expandable support member having a cuff-like configuration and including a main body portion (MBP). The MBP includes a lumen for engaging a wall of a blood vessel including a portion of a renal vasculature. At least one electrode connected with the MBP is arranged to selectively deliver electric current to a desired location. An insulative material is attached to at least a portion of the MBP. Next, the MBP is implanted extravascularly so that the MBP is in direct contact with a portion of the renal vasculature. At least one electrode is positioned substantially adjacent a desired location where modulation of the sympathetic nervous system (SNS) is effective to alter renal function. Electric current is then delivered to the at least one electrode to effect a change in the SNS.

    摘要: A hybrid stent graft device for treatment of a Type A dissection having a first tubular portion for placement into the ascending aorta and a second tubular portion for extending around the thoracic arch and down the descending aorta is disclosed. The first tubular portion is connectable to the aorta between the sinotubular junction and the brachiocephalic artery so that it essentially replaces the ascending aorta. A temporary bypass tube allows perfusion during an operation. The second tubular portion has an elongate recess outside of the second tubular portion and an aperture defining a fluid flow path into the recess. The recess is intended to engage an outer curve of the thoracic arch to enable blood flow into the arteries of the thoracic arch. An introduction device in combination with the hybrid stent graft described above is also disclosed.
