The described invention provides an endovascular device comprising a tube comprising a first end comprising a bifurcation and a second end comprising an opening. The bifurcation at the first end comprises a first branch and a second branch. The opening at the second end comprises a primary opening and a secondary opening. The first branch and the primary opening form a working lumen. The second branch and the secondary opening form a support lumen. The described invention further provides an endovascular device comprising a tube comprising a side-hole, a first segment comprising a primary opening and a second segment. The side-hole and the first segment form a working lumen. The second segment forms a support lumen.

A system for spinal surgery includes a prosthesis comprising a plurality of bone anchors which engage an intervertebral construct for fusion or motion preservation. The fusion construct comprises a spacer optionally encircled by a jacket. The motion preservation construct may comprise an articulating disc assembly or an elastomeric disc assembly. Any of the constructs may occupy the intervertebral disc space between adjacent vertebrae after removal of an intervertebral disc. The anchors slidingly engage the construct to securely fix the prosthesis to the vertebrae. The anchors and jacket of the fusion construct provide a continuous load path across opposite sides of the prosthesis so as to resist antagonistic motions of the spine.

Methods of implanting a device in the lumen of a blood vessel are described. The method includes providing a microcatheter and a device. The device includes a first hub, a second hub, a support structure including a plurality of struts disposed between the first hub and the second hub, and a layer of material disposed over the plurality of struts. The support structure has a low profile, radially constrained state with an elongated tubular configuration suitable for delivery from a microcatheter. The support structure also has an expanded state, a smooth outer surface, and has an axially shortened configuration relative to the radially constrained state. The microcatheter is advanced to a region of interest within the blood vessel. The support structure is advanced through the lumen of and out the distal end of the microcatheter where it expands to the expanded state.

A lubricated tubular graft is implanted in the inferior vena cava and the superior vena cava in order to control the inflow of blood to the right atrium. A bifurcated leg with a non-collapsing stent extends across the tricuspid valve. A bioprosthetic valve is positioned proximal of the stent in the bifurcated leg in order to regulate flow through the tricuspid valve and to eliminate tricuspid regurgitation.

An intraluminal stent (1) and a preparation method therefor are provided. The intraluminal stent (1) includes at least one sub-stent. The sub-stent includes at least a first wire (4) extending along a first spiral direction and at least a second wire (5) extending along a second spiral direction, and the first wire (4) and the second wire (5) extend in different directions to form several wire intersection points. The intraluminal stent (1) has several wrapped portions (2) to wrap two corresponding wire tail ends. A wrapping connector (3) is disposed at a periphery of the wrapped portion (2). Two end portions of the wrapping connector (3) are firmly connected to regions corresponding to two ends of the wrapped portion (2). The two wire tail ends of the wrapped portions (2) are wrapped by using the wrapping connector (3). The stent (1) is less harmful to intraluminal tissues and a relatively strong tensile resistance.

A valve connector for a tunable valve is disclosed, with tunable features to allow for optimization. The tunable valve can include slits, which may be preferentially placed, angled and sized to optimize the crack pressure, maintenance pressures, and clearance characteristics of the connector. The tunable valve may also include a recess in the area of an exemplary center slit, which may be sized further modify the characteristics of the connector valve. The valve may be preferentially curved along either a lateral axis or a transverse axis. The tunable valve may be a proximal valve that is capable of being secured between proximal housing and distal housing. The proximal housing opening may be preferentially shaped.

An implantable and removable filter that may be implanted in and/or removed from a body lumen, such as the Vena Cava. The filter including tissue anchors on expandable anchoring legs, which can be selectively moved between a non-anchoring or pre-deployed configuration into an anchoring or deployed configuration by obturators that are movable inside the anchoring legs.

A hair implant suitable for subcutaneous implantation is provided having an anchor comprising an anchor body, and at least one collagen receiving structure selected from the group consisting of at least one tunnel disposed through the anchor body and an external surface feature of the anchor body. The anchor further comprises at least one hair strand projecting from a distal end of the anchor body, wherein the at least one collagen receiving structure is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the anchor to a hair implant recipient, and the collagen receiving structure is free of hair.

A prosthetic mitral valve may be anchored in a native mitral valve. The prosthetic mitral valve preferably has a large anterior prosthetic leaflet that spans the entire width of the native anterior leaflet and the anterior prosthetic leaflet moves away from left ventricular outflow tract during systole to create a clear unobstructed outflow path.

Described are implants, intermediate articles of manufacture (web constructions) useful for preparing implants, methods of forming the implants and intermediate articles, and related methods for treating pelvic conditions by use of the implants. The present invention relates generally to surgical implants (i.e., “implants”), intermediate articles of manufacture (web constructions) useful for preparing surgical implants, methods of forming the implants and intermediate articles, and related methods for treating pelvic conditions by use of the implants.
