METHOD FOR PRODUCING A STORABLE MOLDED BODY MADE OF BACTERIAL CELLULOSE AND A MOLDED BODY PRODUCED ACCORDING TO THE METHOD
20170312398 · 2017-11-02 ·

The invention relates to a method for producing a storable molded body made of bacterial cellulose and a molded body produced according to the method. A preferred method includes providing a molded body made of bacterial cellulose. Optionally, mechanically pressing the entire molded body or parts of the molded body at temperatures in the range of 10° C. to 100° C. and pressures in the range of 0.01 to 1 MPa for a pressing time of 10-200 min. Treating the molded body with a solution of 20% by weight to 50% by weight of glycerol and 50% by weight to 80% by weight of a C1-C3-alcohol/water mixture. Drying the treated molded body.

VASCULAR FILTER

An inferior vena cava filter (340) for use in the inferior vena cava (4) to capture thrombus (8) passing through the inferior vena cava (4) towards the heart and lungs to prevent pulmonary embolism comprises a proximal support hoop (302), a distal support hoop (312) and a plurality of support struts (303) extending between the proximal support hoop (302) and the distal support hoop (312). The filter (340) also comprises a plurality of capture arms (121) which are movable from a capturing configuration to an open configuration. The capture arms (121) are biased towards the open configuration. A biodegradable suture holds the capture arms (121) in the capturing configuration.

Intervertebral implant with blades for connecting to adjacent vertebral bodies

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

Femoral neck prosthesis
09763790 · 2017-09-19 · ·

The invention relates to a shaft for a femoral neck prosthesis, which comprises an anchoring area (27, 29) which is arranged inside the femur in order to anchor the prosthesis into bone, a head area which is axially adjacent to the anchoring area (27, 29) on the proximal side, said head area comprising a device (13) which is connected to the prosthesis head (15), in addition to a distal end which is arranged opposite the head area in the axial direction of the anchoring area (27, 29). The invention is characterised in that the maximum cross-sectional dimension of the head area is at the most equal and, in particular, smaller than the maximum diameter of the anchoring area (27, 29), in such a manner that the maximum cross-sectional dimension of the shaft (11) is in the anchoring area (27, 29).

Assembled implant

This invention is directed to an assembled implant comprising two or more portions of bone that are held together in appropriate juxtaposition with one or more biocompatible pins to form a graft unit. Preferably, the pins are cortical bone pins. Typically, the cortical pins are press-fitted into appropriately sized holes in the bone portions to achieve an interference fit. The bone portions are allograft or xenograft.

Systems and methods for manufacturing a stent frame

A prosthetic heart valve can include a support structure, an actuator member, and a plurality of leaflets. The support structure can have a plurality of struts and a plurality of rivets. The struts can have openings formed therein. The rivets can have first portions and second portions. The first portions can extend through the openings of the struts, and the second portions are larger than the first portion and the openings of the struts. The struts are pivotable about the rivets to radially expand and compress the support structure. The actuator member can be coupled to the struts of the support structure and configured to selectively actuate expansion and compression of the support structure. The leaflets can be coupled to the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve.

TRANSVALVULAR INTRAANNULAR BAND FOR MITRAL VALVE REPAIR

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

Valve Prosthesis

The present disclosure relates to valve replacement devices that are foldable for catheter-based deployment to the site of implantation, as well as systems for the delivery of valve prostheses, including prostheses having the special characteristics of the disclosed valve replacement devices. The devices include highly effective adhering mechanisms for secure and enduring precision implantation. The adhering mechanisms may employ a unique sealing mechanism that includes a cuff that expands slowly whereby the device is not secured in place until the completion of the implantation procedure. The implanted device, optionally together with the cuff, prevents perivalvular leaks and incorporate an appropriate leaflet system for reliable functioning in situ.

Stent

In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.
