PROSTHETIC MITRAL VALVE AND DELIVERY METHOD
A valve prosthesis and methods for implanting the prosthesis are provided. The prosthesis generally includes a self-expanding frame and two or more engagement arms. A valve prosthesis is sutured to the self-expanding frame. Each engagement arm corresponds to a native mitral valve leaflet. At least one engagement arm immobilizes the native leaflets, and holds the native leaflets close to the main frame. The prosthetic mitral valve frame also includes two or more anchor attachment points. Each anchor attachment point is attached to one or more anchors that help attach the valve prosthesis to the heart.
Intra-articular joint replacement
A method of forming a shoulder prosthesis includes resecting an end portion of a humerus to form a resected end of the humerus and a resected portion separated from the humerus, the resected portion having an outer convex surface and an inner surface. The inner surface of the resected portion is processed to include a concave articular surface. The outer convex surface of the resected portion is implanted in the resected end of the humerus. An implant having a convex articular surface is secured to a glenoid. The concave articular surface of the resected portion is articulated with the convex articular surface of the implant.
ACCOMMODATIVE INTRAOCULAR LENS
An accommodative intraocular lens includes a first lens part, a haptic, and a flexible membrane. The flexible membrane is arranged adjacent to a distal optical body surface, delimits a cavity together with the distal optical body surface and is transparent to light. A second lens part has a hollow cylinder coupled releasably to the first lens part, as a result of which the intraocular lens can be brought into a coupling state in which the second lens part is arranged on a distal side of the first lens part and the hollow cylinder is configured to deform the membrane by a longitudinal displacement of the hollow cylinder parallel to the optical axis. The hollow cylinder has on its exterior an outer face and a bearing face arranged adjacent to a proximal end of the outer face and encloses, with the outer face, an angle of less than 180°.
Systems and methods for treating cardiac dysfunction
A system for treating cardiac dysfunction can include an expandable device for insertion into a heart, a foot configured to contact a portion of the heart, a support frame, and a membrane coupled to the support frame. The support frame can include a plurality of radially expandable struts each having a first free end configured to extend beyond the foot and a second end coupled to the foot. The plurality of radially expandable struts can include a plurality of staggered stops, and each of the stops can be positioned on a respective one of the struts proximal to the first free end of the respective one of the struts. Method for treating cardiac dysfunction can include implanting the systems described herein into a chamber of the heart.
Vertebral implants and attachment assemblies
A prosthetic implant for engagement between first and second vertebrae. The implant includes a first plate configured for attachment to the first vertebrae and defining a first interbody connection member and a second plate configured for attachment to the second vertebrae and defining a second interbody connection member. An interbody component includes a body with a first end defining a first plate connection member configured for connection to the first interbody connection member and a second end defining a second plate connection member configured for connection to the second interbody connection member. A method of inserting the implant is also provided.
Glenoidal component, set of such components and shoulder prosthesis incorporating such a glenoidal component
This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centred on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.
Detachable sliding actuators for valve repair devices
Various embodiments of an implant delivery systems including at least one removable actuator to reshape a valve annulus are described. The systems may use the removable actuator to customize annular reshaping at a treatment site and withdraw the actuator from the treatment site following custom reshaping to provide a low profile annuloplasty implant.
Stent Graft
The present invention belongs to the field of medical devices, and specifically relates to a stent-graft. The stent-graft has a proximal greater curvature side and a proximal lesser curvature side. The stent-graft includes a stent body, an inner cover membrane disposed on the inner side of the stent body, and an outer cover membrane disposed on the outer side of the stent body. The stent body includes a plurality of wave rings axially arranged at intervals. Alternatively arranged crests and troughs are formed on the wave rings. The outer cover membrane is provided with a first opening, and the first opening exposes at least one trough located at or nearer to the proximal greater curvature side. According to the stent-graft of the embodiments of the present invention, the exposed trough can easily hang on a vessel wall, and thereby achieving the function of preventing the stent-graft from shifting. The crests and troughs located at the proximal lesser curvature side of the stent-graft remain covered by the outer cover membrane. Therefore, the stack state of the cover membrane and the wave ring in a stent lumen is in the blood flow direction, thereby reducing the risk of thrombosis.
CEMENT RETAINING IMPLANT STEM FOR PERMANENT FIXATION
The present invention relates to a stem for or of an implant having a longitudinal axis and at least one recess adapted for cemented implantation into the medullary cavity and/or a cavity created by surgery of a long bone, characterized in that the recess is interrupted by a barrier. Further the present invention relates to a method for preparing a stem of an implant according to any one of the preceding claims for implantation, comprising the step of placing cement into the recess (12) on both sides of the barrier.
Systems and methods for making encapsulated hourglass shaped stents
Systems and methods for the manufacture of an hourglass shaped stent-graft assembly comprising an hourglass shaped stent, graft layers, and an assembly mandrel having an hourglass shaped mandrel portion. Hourglass shaped stent may have superelastic and self-expanding properties. Hourglass shaped stent may be encapsulated using hourglass shaped mandrel assembly coupled to a dilatation mandrel used for depositing graft layers upon hourglass shaped mandrel assembly. Hourglass shaped mandrel assembly may have removably coupled conical portions. The stent-graft assembly may be compressed and heated to form a monolithic layer of biocompatible material. Encapsulated hourglass shaped stents may be used to treat subjects suffering from heart failure by implanting the encapsulated stent securely in the atrial septum to allow blood flow from the left atrium to the right atrium when blood pressure in the left atrium exceeds that on the right atrium. The encapsulated stents may also be used to treat pulmonary hypertension.
