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.

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.

A tube stent delivery system is provided that has a simple structure and is capable of releasing a tube stent. A tube stent has a first tube wall section in an annular shape, a hollow first insertion section surrounded by the first tube wall section, and a first fitting section fitted to an outer catheter, and the first fitting section has a first fitting piece, a first fitting hole, and a first body. The outer catheter has a second tube wall section in an annular shape, a hollow second insertion section surrounded by the second tube wall section, and a second fitting section for fitted to the tube stent, and the second fitting section has a second fitting piece, a second fitting hole, and a second body.

After a prolonged period in the body, an IVC filter can be substantially absorbed by the body. When this occurs, it can be very difficult and/or dangerous for the patient if the IVC filter is forcibly removed. Thus, it is desirable to have systems and methods for safely abandoning the removal procedure of the IVC filter. Example embodiments of an apparatus for safely abandoning the removal procedure of the IVC filter can include: a sleeve having a lumen and a first hole on a wall of the sleeve; a shaft slidably disposed within the lumen of the sleeve; a flexible distal extension comprising a braid structure with a first opening; and a first lasso encircling a portion of the first opening of the braid.

A prosthetic insertion apparatus and related methods of use in delivering filled prosthetic bladders through a skin incision and into a surgical cavity or pocket. The prosthetic insertion apparatus imparts control and retention properties to a surgical professional such the prosthetic bladder can be oriented and manipulated into the surgical cavity without risk of inadvertent dropping of the prosthetic bladder and without imparting damaging stress or torque to the bladder. Suitable materials can be utilized that are selected as having advantageous properties including lubricity, rigidity, easily sterilizable, and high strength.

Prosthetic heart valve leaflets of shapes that control bending. Prosthetic heart valves can include a leaflet frame having a generally tubular shape with attached film. The leaflet frame can define a plurality of leaflet windows with the film defining at least one leaflet extending from each of the leaflet windows. Each leaflet attachment zone on the leaflet frame may have substantially the shape of an isosceles trapezoid having two leaflet sides, a leaflet base and a leaflet free edge opposite the leaflet base. The two leaflet sides can diverge from the leaflet base, the leaflet base being substantially flat.

A flow diversion device for the treatment of intracranial aneurysms and other medical conditions is disclosed. The flow diversion device may include a generally tubular wire stent frame formed from a plurality of zig-zag shaped wire elements that are coupled together. The device further includes a base layer of graft material coupled to the wire stent frame and surrounding at least a portion thereof, the wire stent frame maintaining the base layer in an open condition. In some embodiments, the base layer may be formed of porous graft material having a plurality of slits formed in the longitudinal direction. The slits may have a different shape in a compressed configuration and an expanded configuration. The slits provide a passageway for a small blood flow to maintain the long-term patency of important small side branches, while also reducing blood flow to the aneurysm to promote occlusion and avoid potential rupture.

Described embodiments are directed toward prosthetic valves having leaflets of particular shapes that control bending character. In accordance with an embodiment, a prosthetic valve has a plurality of leaflets. Each leaflet includes a central region and two side regions on opposite sides of the central region. The central region is defined by a shape of an isosceles triangle defined by two central region sides, the leaflet base and the leaflet free edge, wherein the two central region sides converge from the leaflet base. Each of the two side regions has a shape of a triangle and each is defined by one of the central region sides, one of the leaflet sides, and the leaflet free edge.

The present invention concerns an intraluminal vascular prosthesis for implantation into the heart and/or cardiac vessels of a patient, in particular for anchoring in the region of the cardiac valve leaflets. The vascular prosthesis comprises a stent support and a prosthesis material at least partially covering the stent support, such, that a covered proximal portion and a non-covered distal portion are formed. Furthermore, the vascular prosthesis has at least one elongate wire-shaped anchoring structure at the proximal end, which is substantially loop-shaped and which is fixed at two ends to the stent support and which is positioned with its proximal end in the form of a loop pointing in the proximal direction and projecting beyond the proximal end of the stent support.
