Abstract: A device for surgically coupling a soft tissue graft into a tunnel of a bone. The device includes a first member and a second member. The first member includes a first graft-engaging surface extending from a first end to a second end of the first member. The second member includes a second graft-engaging surface extending from a first end to a second end of the second member. The first graft-engaging surface and the second graft-engaging surface define a graft-accepting through-passage with a longitudinal axis extending therethrough when the first member is secured to the second member.

Abstract: A medicinal device with a tubular wall made of webs which delimit the cells, and a flexible membrane which forms at least one flap which has a first end connected to at least one first web of a cell, and a free second end which is disposed opposite the first end in the longitudinal direction of the flap. The flap, in the closed position, extends along the tubular wall and at least partially closes the cells, and can be moved to an open position in which the flap is radially deviated in relation to the wall in order to open the cells in a valve-like manner.
Abstract: An implant includes a collapsible anchor to be deployed within a lumen and a protrusion coupled to the anchor. The protrusion, in a constrained state, extends a distance from an exterior surface of the anchor and, in an unconstrained state, extends further from the exterior surface of the anchor. Also included is a biodegradable constraint, such as a biodegradable tube or suture, configured to maintain the protrusion in the constrained state until the constraint releases. The implant may include additional biodegradable constraints, each constraint configured to maintain the protrusion in a different constrained state and to degrade over a different predetermined period after the implant has been deployed within the lumen. The protrusion may include a bi-directional barb or an open loop. The protrusion may be configured to penetrate a wall of the lumen and to allow tissue to grow about the protrusion.

Abstract: Provided is alloy for medical use and a medical device that is novel and useful. The alloy for medical use according to, for example, an embodiment of the present invention is mainly composed of three kinds of elements of gold (Au), platinum (Pt), and niobium (Nb). A total content of the three kinds of elements can be no smaller than 99% by weight, in which a platinum content can be no smaller than 5% by weight and no greater than 50% by weight and a niobium content can be no smaller than 3% by weight and no greater than 15% by weight. By adjusting the content ratio of the three elements, for example, it is possible to reduce or prevent artifacts in an MRI. Non-magnetization is also possible.

Abstract: An intraocular lens for providing accommodative vision includes an adjustable optic and a haptic that is operably coupled to the optic. The adjustable optic comprises a central zone and an annular zone surrounding the central zone. The optic may also comprise additional annular zones. The haptic comprises a transparent portion protruding into the adjustable optic. The intraocular lens has a disaccommodative configuration in which the central zone has a base optical power and an accommodative configuration in which the central zone has an add optical power that is at least about 1 Diopter greater than the base optical power. The central zone and the annular zone have different optical powers when the adjustable intraocular lens is in the accommodative configuration and/or when the adjustable intraocular lens is in the disaccommodative configuration.

Abstract: A vascular prosthesis comprising a tubular shaped expandable ECM member and at least one anchoring mechanism. In one embodiment, the anchoring mechanism comprises proximal and distal single or dual-ring anchors. In one embodiment, the anchoring mechanism comprises a multiple-ring anchor. The anchors preferably comprise a biodegradable metal, such as magnesium. The anchors can also comprise a shape memory alloy, such as nitinol, and a cross-linked ECM material. In some embodiments, the ECM member includes a pharmacological agent.
Abstract: A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.

Abstract: The invention relates to a device (1) for the vision correction of an eye (6), comprising: a converter (3, 3A, 3B, 5A, 5B) which can generate an electrical and/or magnetic and/or electromagnetic signal in response to the mechanical energy generated by a movement of the eye; and a soft lens (2) intended to be aligned with the eye. The converter is positioned in relation to the lens such that the electrical and/or magnetic and/or electromagnetic signal generated during the movement of the eye causes the optical properties of the lens to change. The invention is characterised in that the lens (2) includes a polymer material (7) containing a material (4) having a refractive index that can vary under the action of the electrical and/or magnetic and/or electromagnetic signal generated during a movement of the eye.

The prosthesis also includes a proximal fixation member configured to apply a second axial force to tissue of the subject on an upstream side of the native valve complex such that application of the first and second axial forces couples the prosthesis to the native valve complex. The proximal fixation member and the distal fixation member are fabricated as one integrated structure.

Abstract: A prosthesis is provided for implantation at a native semilunar valve of a native valve complex. The prosthesis includes a distal fixation member, configured to be positioned in a downstream artery, and shaped so as to define exactly three proximal engagement arms that are configured to be positioned at least partially within respective ones of semilunar sinuses, and, in combination, to apply, to tissue that defines the semilunar sinuses, a first axial force directed toward a ventricle. The prosthesis further includes a proximal fixation member coupled to the distal fixation member, the proximal fixation member configured to be positioned at least partially on a ventricular side of the native semilunar valve, and to apply, to the ventricular side of the native valve complex, a second axial force directed toward the downstream artery, such that application of the first and second forces couples the prosthesis to the native valve complex.
