An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D−24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

An endovascular anastomotic connector and method of using the same. The endovascular anastomotic connector includes a vascular conduit and a supply conduit. The vascular conduit has proximal and distal ends that reside within a vascular structure. The supply conduit extends at an angle from the vascular conduit. The proximal end of the supply conduit is configured to be attached to an auxiliary device.

A device includes a first end portion, a second end portion, an intermediate portion between the first end portion and the second end portion, and a graft material coupled to at least the intermediate portion. The first end portion has a first end diameter. The second end portion has a second end diameter larger than the first end diameter. The intermediate portion tapers between the first end portion and the second end portion. A method of diverting fluid flow from a first passage to a second passage comprising deploying the device in a third passage between the first passage and the second passage, expanding the first end portion against sidewalls of the first passage, and expanding the second end portion against sidewalls of the second passage.

Devices, systems, and methods for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.

A vascular access device, for implantation at least partially below the skin of a patient to provide an arteriovenous fistula, includes a graft portion coupled to a catheter portion. The graft portion is sutured to an opening in an artery while the catheter portion is inserted into a vein so that its end lies within the vein downstream from the point of entry into the vein. The device may be comprised of ePTFE with an outer polyurethane coating or the graft portion may comprise ePTFE with an outer polyurethane coating and the catheter portion may comprise polyurethane. There may also be an inner polyurethane coating. Alternatively, the device may be comprised entirely of polyurethane.

An endoluminal prosthesis system deployable in a region of a patient's vasculature having one or more branch vessels, having a main graft body having a first opening in a wall portion of the main graft body and a pre-loaded guidewire positioned inside the main graft body and advanced through the first opening. One or more branch grafts can be attached to the main graft body to cover one or more openings in the main graft body.

A sheath for retaining a prosthesis for use in repair of a damaged portion of a body vessel during an open surgical procedure. The prosthesis is of a type having a constricted condition for delivery to the damaged vessel portion and an expanded condition upon deployment from the sheath. The sheath includes a generally cylindrical body having a distal end portion, a proximal end portion, a passageway extending therethrough, and an elongated tab member at the proximal end portion. The tab member is positionable along the generally cylindrical body for initiating the splitting of the generally cylindrical body from the distal end portion of the sheath body toward the proximal end portion.

A tubular graft comprising an internal helical formation which imparts helical flow on fluid passing through the tubular graft. One end of the tubular graft is tapered from an inner base to an outer tip.

An in-situ non-reversed femoral-popliteal bypass procedure is provided, the procedural method embodies harvesting a portion of a saphenofemoral junction as the anastomosis for said in-situ non-reversed femoral-popliteal bypass, wherein a portion of the common femoral vein is the patch of the proximal end of the anastomosis. The practitioner may intubate the anastomosis through its distal end with an expandable balloon- prior to grafting said proximal end to the femoral artery; and selectively expanding the expandable balloon at or near said proximal end.
