In an embodiment, a medical device is a bodily implant and includes an elongate member. The elongate member has an inner edge that defines an opening. At least a portion of the inner edge being treated.

One aspect of the invention provides a flow-diverting system including: a first stent having a proximal end, a distal end and a first sidewall opening; and a second stent having a proximal end, a distal end and a second sidewall opening. The first sidewall opening is of sufficient size for the distal end of the second stent to pass from inside the first stent through the first sidewall opening. The second sidewall opening is of sufficient size for fluid flow from inside the second stent through the second sidewall opening into the first stent.

A visceral double-barreled main body stent graft and methods for its use, the stent graft comprises, a main body stent graft having distal and proximal ends, the main body stent graft's length ranges from about 100-120 mm and diameter at the proximal end ranges from about 30-45 mm, first and second lumens defined at the main body stent graft's distal end, the first lumen's diameter ranges from about 18-20 mm, the second lumen's diameter ranges from about 16-18 mm, the first and second lumens have about the same length from about 50-70 mm, the first lumen is secured to the second lumen along a shared length, and the main body stent graft defines a tubular wall that is contiguous with the first and second lumens such that any fluid entering the main body must exit through one of the first or second lumens.

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.

Devices, systems and methods for situating a device within a variety vasculature morphologies are provided. An expandable device can adapt to the local vasculature morphology and still provide a controlled inner diameter is described. A device for situating within the inferior vena cava and superior vena cava is described. Systems and methods for utilizing devices are described.

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.

Bioabsorbable scaffolds having high crush recoverability, high fracture resistance, and reduced or no recoil due to self expanding properties at physiological conditions are disclosed. The scaffolds are made from a random copolymer of PLLA and a rubbery polymer such as polycaprolactone.

The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.

A stent is to be placed within a biological lumen (HP) and is provided with: stent parts that have a tubular shape and can expand and shrink in a radial direction that is approximately perpendicular to the axial direction; and transformation means that can transform the stent parts from a reduced diameter state to an expanded diameter state. The transformation means have: first linear members wound around the outer circumferential surfaces of the stent parts; and holding members for holding the first linear members non-detachably from the stent parts. The first linear members are engaged with the holding members to maintain the stent parts in the reduced diameter state, and the engagement is released to transform the stent parts from the reduced diameter state to the expanded diameter state.

Devices and methods for treating heart disease by increasing the pulmonary vascular compliance and thereby decreasing the right ventricular afterload are disclosed. Devices may include a means for reducing the cross-sectional area of the pulmonary artery during diastole and allowing the cross-sectional area to increase during systole.
