Abstract
Flexible prosthetic implants for repairing, replacing or augmenting hard tissue or bone. The flexible implant comprises a plurality of segments that are connected by flexible retainers which enable the segments to be re-oriented in relation to one another to accommodate the contour, size and shape of the body part being treated. A method for making such flexible prosthetic implants is also disclosed.
Claims4
A method of making a prosthetic implant comprising the steps of:
- partially filling a mold having two spaced apart cavities with material suitable for forming prosthetic implants;
- placing a flexible retainer between the two partially filled cavities so the retainer extends partially into each cavity;
- filling said mold to cover the retainer;
- curing the material to form a prosthetic implant;
- and
- removing the prosthetic implant from the mold wherein the prosthetic implant includes at least two segments which are connected by the flexible retainer such that the segments and the flexible retainer cooperate to conform the prosthetic implant to the contour of at least a portion of underlying maxillofacial bone.
3 more elements
A method of making a prosthetic implant comprising:
- a) placing at least two segments in an adjacently spaced apart relation;
- b) molding around said segments so as to form a mold having at least two cavities which are separated from one another by at least one wall of said mold;
- c) removing a portion of said at least one wall, the portion corresponding to the size and shape of a retaining member to permit the retaining member to be situated to traverse adjacent cavities;
- d) partially filling said mold cavities with a material suitable for forming prosthetic implants;
- e) placing a flexible retainer member between said adjacent cavities such that said retainer member traverses said wall between adjacent cavities;
- f) further filling said mold cavities with the material suitable for forming prosthetic implants;
- g) curing the material suitable for forming prosthetic implants so as to form a prosthetic implant having at least two segments connected by the flexible retaining member;
- and
- h) removing the prosthetic implant from the mold wherein the segments and the flexible retaining member cooperate to conform the prosthetic:
- implant to at least a portion of underlying maxillofacial bone.
