Intravascular devices and systems useful for blocking the opening of an aneurysm or a vessel branch are disclosed. In some aspects, the disclosure provides arrangements that align a covering material of a stent graft with an opening in the vessel wall before, during, and/or after expansion of the stent graft within the vasculature of a patient. In some instances, systems and devices include a sheath with a side aperture arranged to align a portion of the sheath and/or a portion of a stent graft contained within the sheath with the mouth of an aneurysm. Similarly, the present disclosure also provides embodiments in which the stent graft comprises an aligning member arranged to align the stent graft and/or a sheath with the mouth of an aneurysm. Other embodiments are disclosed.

In a representative embodiment, a method comprises implanting first and second inflatable bodies within an annulus of a native heart valve by securing the inflatable bodies to tissue of the native heart valve with sutures, and implanting a prosthetic heart valve between the inflatable bodies such that the prosthetic heart valve is retained within the annulus by the inflatable bodies.

Stents that are adapted to be balloon expanded and include adjacent supports connected by connecting portions. The configurations, materials, and/or dimensions of at least one of the supports and connection portions allows the stents to be expanded to a greater extent, and optionally with reduced foreshortening.

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.

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.

An implantable prosthetic valve can comprise an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, the frame defining an axial direction extending from the inflow end to the outflow end, a leaflet structure positioned within the frame and secured thereto, and an annular outer skirt positioned around an outer surface of the frame, wherein the outer skirt comprises an inflow edge secured to the frame at a first location, an outflow edge comprising a plurality of alternating projections and notches, wherein the projections are secured to the frame at a second location, and the notches are not directly secured to the frame, an intermediate portion between the inflow edge and the outflow edge that comprises a plurality of openings.

A hip implant having two distinct bodies, a neck body and a bone fixation body. The neck body is formed from a solid metal and has an interface for connecting to a femoral ball. The bone fixation body has an elongated shape and is formed as a porous structure that is inserted into an intramedullary canal of a patient.

The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.

A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.

A collapsible and expandable stent body includes a generally tubular annulus section, one or more prosthetic valve elements mounted to the stent body, and a cuff attached to the stent body. The prosthetic valve is operative to allow flow in an antegrade direction but to substantially block flow in a retrograde direction. The prosthetic heart valve may include paravalvular leak mitigation features in the form of first and second sealing members. The sealing members are attached to the cuff and extend circumferentially around an abluminal surface of the stent body. The sealing members each have an open side facing in a first axial direction and a closed side facing in an opposite second axial direction. Flow of blood in the second axial direction will tend to force blood into the sealing members and cause the sealing members to billow outwardly relative to the stent body, helping to mitigate paravalvular leak.
