A venous valve with a frame and a cover on the frame for unidirectional flow of a liquid through the valve.

A vessel filter comprising a first region and a second region wherein the filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. A first region has a filter portion having a converging region to direct particles toward the center of the filter and the second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the first end portion. The second region includes a vessel engaging portion at the second end portion. The first region includes a plurality of spaced apart elongated struts with adjacent struts being joined.

One aspect of the present disclosure can include a frame structure adapted for use with a stent graft. The frame structure can include a scallop region and a Z-form region. The scallop region can have a first end portion, a second end portion, and a perimeter that defines an aperture. The Z-form region can extend from the scallop region and include a plurality of Z-shaped struts, each of which has a first end and a second end that is connected to the scallop region at different points so as to form a central frame structure lumen. The second end portion of the scallop region can include a backstop that is deployable from a first flattened configuration to a second erect configuration. The backstop, in the second erect configuration, is sized and dimensioned to extend into a lumen of an aortic branch vessel.

A vascular filter (1) comprises a proximal support hoop (3), a plurality of support struts (5), and a plurality of capture arms (6). The proximal support hoop (3) extends around the internal wall of the inferior vena cava in a wave pattern having six distal peaks (11) and six proximal peaks (11). The proximal support hoop (3) comprises an enlarged end element at each peak (11). The support struts (5) extend longitudinally along the internal wall of the inferior vena cava in a curve (14). Two capture arms (6) are connected to the proximal support hoop (3) at each distal peak (11). Each capture arm 6 extends from the distal peak (11) to an apex (7) in a curve (12, 13). The concave portion of the first curve (12) faces inwardly towards the concave portion of the second curve (13).

A system for implanting a heart valve includes a radially self-expandable tubular body having an inflow end and an outflow end, a decorrelation portion, and a preformed groove disposed at an outer surface of the tubular body between the decorrelation portion and the outflow end. The preformed groove extends at least partially around the tubular body, and has a circumferential opening facing radially outward of the tubular body. A valve is disposed within and attached to the tubular body. The decorrelation portion is configured to dissociate axial and radial movements between the inflow end of the tubular body and the outflow end of the tubular body.

Delivery systems for expandable and stented implants include adjustable tensioning members that control the expansion of the implant along the length of the implant. The tensioning members are wound onto one or more rotors located on the distal segment of the delivery system, which are rotated to unwind the tensioning members and incrementally expand the implant. Positioning mechanisms are also provided to adjust the position and orientation of the implant during delivery.

An endoprosthesis may include an expandable framework including a body portion disposed between a first end and a second end, and a bowl portion disposed along the body portion; and a polymeric cover disposed on at least a portion of the expandable framework. The bowl portion may include an inner surface and an outer surface spaced apart radially outward from the inner surface. The bowl portion may extend radially outward from the body portion. The inner surface of the bowl portion may be devoid of the polymeric cover.

Disclosed herein are gender-specific implantable mesh for inguinal hernia repair in a patient, comprising: a fabric layer comprising a side defining a surface area wherein the fabric layer is configured to enable tissue adhesion to said mesh; an anti-adhesive barrier comprising a shape configured to prevent direct contact between the fabric layer and both a spermatic cord and a genital nerve upon implantation, wherein the shape covers a part of the surface area on the side of the fabric layer, the part being less than 25%, and wherein the shape is oblique to a horizontally-oriented centerline and a vertically-oriented centerline; and a keyhole configured to fit the genital nerve and the spermatic cord of the patient therethrough without constriction, wherein the keyhole is oblique and inferior to a horizontally-oriented centerline and medial to a vertically-oriented centerline.

An illustrative stent may comprise an elongated tubular member having a first end and a second end and an intermediate region disposed therebetween. The elongated tubular member may include at least one flexible tie affixed to an end thereof. The tie may allow the stent to be attached to a lumen wall with a clip, such as a retention clip, to inhibit migration of the stent within the body lumen.

A removable dual endovascular filter that may be introduced into arteries of the heart during surgery to allow sufficient blood flow to a cerebral vascular system while minimizing or preventing embolic material from traveling throughout a body circulatory system. The removable dual endovascular filter reduces the risk of stroke while minimizing obstruction of the patient's aorta.
