Abstract: A stent includes a first wire and a second wire. The first wire is helically wound along an axis of a main body portion of the stent and along an axis of a first branch portion of the stent. The second wire is helically wound along the axis of the main body portion of the stent and along an axis of a second branch portion of the stent. The first wire and the second wire ar encapsulated in a graft member. A method for making a stent includes winding a first wire helically along a main body portion of a bifurcated mandrel and a first leg portion of the bifurcated mandrel. The method further includes winding a second wire helically along the main body portion of the bifircated mandrel and a second leg portion of the bifurcated mandrel. The first and second wires can be laminated within a graft material.

Abstract: A stent graft system includes a first graft, a second graft, and a third graft. Each of the first graft, the second graft, and the third graft forms a single lumen. When deployed, the first graft, the second graft, and the third graft are coupled together within an aorta.

Abstract: A prosthetic venous valve includes an expanding anchoring frame, a valve seat at the middle portion of the anchoring frame, a ball disposed within the lumen of the anchoring frame and having an outer diameter, and least one ball retention tether coupled with the ball and the anchoring frame. The ball retention tether includes at least one elastic component or material. The anchoring frame has an upstream end, a downstream end, a middle portion and a lumen extending through the anchoring frame from the upstream end to the downstream end. The ball moves between an open position, in which the ball is located apart from the valve seat, and a closed position, in which the ball is located in contact with or near the valve seat to reduce or prevent backflow of blood through the prosthetic venous valve.

Abstract: Some embodiments relate in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to stent grafts and methods of making and deploying same within the body of a patient. Stent embodiments may include tapered struts for an even distribution of strain. Stent embodiments may also include portions which are enlarged in a circumferential direction which may be configured to stabilize the stent in a constrained state.

Abstract: A limb supporting apparatus adaptable for use during orthopedic surgery on a patient's limb having a platform base; an appendage rest supported by the platform base and adapted to immobilize the limb; an access port supported by the platform base; and a curved cannula supported by the access port and adapted to facilitate access to target bone during orthopedic surgery. Another aspect of the invention provides a method of performing an orthopedic procedure on a limb including the steps of immobilizing the limb on an appendage rest of a platform base; aligning a curved cannula supported by an access port with a target bone of the limb; and performing an orthopedic procedure on the target bone through the cannula.

Abstract: The invention is generally directed to tools, systems and methods of preparing a bone site prior to deployment of bone repair devices. In one embodiment, a bone cutting instrument is provided with a generally rigid arcuate tube having a generally fixed radius and a lumen therethrough, a flexible drive shaft configured to be slidably and rotably received within the tube lumen, and a cutter head attached to an end of the drive shaft, whereby the shaft and cutter head may be first advanced together with the tube in an arcuate manner to cut an arcuate path in a bone, and then advanced in a telescoping manner relative to the tube being held in a generally fixed position to cut a straight path in the bone. Methods of forming a passage in a bone include advancing a cutter head into a bone along a curved path having a generally constant radius, and continuing to advance the cutter along a generally straight path extending from the curved path.
