Abstract
In one embodiment of the disclosure, a prosthetic bone implant includes a prosthesis and a tissue attachment structure connected to the prosthesis. The tissue attachment structure includes a connective structure connected to the prosthesis and an interface structure connected to the connective structure. The interface structure is configured for attachment of tissue thereto. When the interface structure is subject to tension, the connective structure changes in shape.
Claims20
A prosthetic bone implant comprising:
- a prosthesis;
- and
- a tissue attachment structure connected to the prosthesis, the tissue attachment structure comprising:
- a connective structure connected to the prosthesis;
- and
- an interface structure connected to the connective structure and configured for attachment of tissue thereto,
- wherein the connective structure changes in shape when the interface structure is subject to tension.
4 more elements
A tissue attachment structure comprising:
- a porous material layer configured for attachment to tissue;
- a connective structure having a first location and a second location on its length, the connective structure being connected to the porous material layer at the first location and configured for connection to a prosthesis at the second location,
- wherein the connective structure is a spring or an auxetic structure.
A tissue attachment structure comprising:
- a first material layer configured for attachment to tissue;
- a second material layer having lower porosity than the first material layer, the second material layer connected to the first material layer;
- at least one connective structure connected to the second material layer so that the second material layer is in between the connective structure and the first material layer, the at least one connective structure adapted to change in shape when subject to tension,
- wherein the connection between the at least one connective structure and the second material layer is at a first location on the connective structure and the at least one connective structure is configured to be connected to a prosthesis at a second location on the connective structure, and
- wherein when the at least one connective structure is connected to the prosthesis, a distance between the first location and the second location changes when at least one of the first and second material layers is subject to tension.
