A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20° C. to +170° C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.

The present invention is directed to a low profile intervertebral implant for implantation in an intervertebral disc space in-between adjacent vertebral bodies. The intervertebral implant includes a plate preferably coupled to a spacer. The plate is preferably formed from a first material and the spacer is preferably formed from a second material, the first material being different from the second material. The plate is preferably sized and configured so that the plate does not extend beyond the perimeter of the spacer. In this manner, the plate preferably does not increase the height profile of the spacer and the plate may be implanted within the intervertebral disc space in conjunction with the spacer.

A cup and a temporary insert are respectively configured to be tightly press fitted into each other along their periphery. The temporary insert includes a through hole communicating outside with a free space between the outer surface of the temporary insert and the inner surface of the cup. In the through hole can be engaged the threaded end of an impactor, for manipulating the cup when it is being set. A syringe can be engaged, enabling a liquid under pressure to be injected into the free space, thus separating the temporary insert from the cup without any risk of damaging the inner surface of the cup. Thus, the cup can be securely manipulated when it is being set without any risk of damaging the inner surface of the cup.

To increase the resistance to liquid and substance flow through a lumen of a tubular organ, a flexible apparatus is appended to an exterior wall of the tubular organ such that it only partially surrounds the tubular organ. Ultimately, tissue ingrowth through the apparatus integrates the apparatus into the wall of the tubular organ. When the apparatus is applied to tubular tissue, flow though the tubular tissue is restricted. The apparatus may also support an optional expandable component, e.g., a balloon-like element that can be selectively inflated and/or deflated to restrict the lumen of the tubular tissue by a desired degree.

Disclosed is a bone fusion cage that contains bone graft and is implanted between bones in a skeletal system. The cage bears structural loads that are transmitted through the bones of the skeletal system and at least partially shields the contained bone graft from the structural loads. The cage is configured to provide a secondary load to the bone graft independent of the structural load to promote fusion of the bone graft to adjacent bones.

A prosthetic device for replacing at least part of one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and comprising an upper endplate, a lower endplate and an expandable support structure extending between the two endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at a minimum axial distance that corresponds to the height of at least one intervertebral disc and half a vertebral body, wherein the expandable support structure includes an anterior post and a posterior post, wherein the length (L1/L2) of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0 to 40 relative to each other.
