    Abstract: A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.

    Abstract: A helical stent includes a central segment having a first tubular waveform and a first end segment having a second tubular waveform. The waveforms are defined by a plurality of struts and a plurality of crowns connecting adjacent struts together. The struts of the second tubular waveform have different lengths such that second tubular waveform includes a plurality of amplitudes. The second tubular waveform comprises a complete turn around a longitudinal axis of the stent. A first connector connects together the first tubular waveform first end, the second tubular waveform first end, and the second tubular waveform second end. Due to the configuration of the second tubular waveform of the first end segment, the stent end at the first end segment is substantially orthogonal to the longitudinal axis of the stent. A second end segment similar to the first end segment can be connected to a second end of the first tubular waveform.

    Abstract translation: 螺旋支架包括具有第一管状波形的中心段和具有第二管状波形的第一端段。 波形由多个支柱和将相邻支柱连接在一起的多个冠部限定。 第二管状波形的支柱具有不同的长度,使得第二管状波形包括多个振幅。 第二管状波形包括围绕支架的纵向轴线的完整转弯。 第一连接器将第一管状波形第一端,第二管状波形第一端和第二管状波形第二端连接在一起。 由于第一端段的第二管状波形的构造,第一端段处的支架端部基本上垂直于支架的纵向轴线。 类似于第一端段的第二端段可以连接到第一管状波形的第二端。

    Abstract: The techniques of this disclosure generally relate to a stent-graft system including a bifurcated stent-graft, a first bifurcating branch device, and a first branch extension. The bifurcated stent-graft includes a body, a first branch limb, and a second branch limb. The first bifurcating branch device includes a body segment coupled to the first branch limb of the bifurcated stent-graft, a first branch limb, and a second branch limb. The first branch extension is within the first branch limb of the first bifurcating branch device and within an external iliac artery. The first bifurcating branch device has a wide patient applicability since the treatment can be extended proximal to the anatomical iliac bifurcation and is not limited by the common iliac artery length. The stent-graft system is suitable to treat a wide range of internal and external iliac artery diameters.

    Abstract: A prosthesis includes a first wire bent into a first waveform and spirally wrapped into a first helix having a plurality of windings that form a hollow cylindrical shape and a second wire bent into a second waveform and spirally wrapped into a second helix having a plurality of windings that form a hollow cylindrical shape. The first and second wires are disposed relative to each other such that the plurality of windings of the first wire and the plurality of windings of the second wire are disposed about a common longitudinal axis and the plurality of windings of the first wire and the plurality of windings of the second wire are axially offset from each other, with windings of the plurality of windings of the first wire alternating or interwoven between windings of the plurality of windings of the second wire along a length of the prosthesis.

    Abstract: In accordance with one embodiment, a helical anchor is provided in a relaxed state. During deployment, a distal portion of the helical anchor is superelastically deformed to protrude longitudinally. The longitudinally protruding distal portion of the helical anchor is longitudinally advanced to cause the distal portion to pierce a prosthesis and a vessel wall. The distal portion returns to the relaxed state after passing through the prosthesis and the vessel wall. By superelastically deforming the distal portion during deployment, it is easier to cause the anchor to penetrate the prosthesis and the vessel wall. Further, by having the anchor return to its relaxed state after passing through the prosthesis and vessel wall, better clamping of the prosthesis to the vessel wall is achieved.
