Patent Images
1. A prosthetic meniscus implant manufactured from resilient polymeric material comprising:
- a generally semi-circular toroidal body having a first end and a second end and having a generally wedge shaped cross section whose apex generates an inferior generally arcuate edge and whose apex-opposing side forms a superior elevated generally arcuate rim, said body composed of flexible and resilient material;
an elongate member, composed of flexible and resilient material, extending from each of said first and said second end of said body and terminating in a free end;
said elongate member incorporating at least one flexible and resilient co-axial anchoring protuberance positioned along the length.

4. A method for implanting a prosthetic meniscus implant comprising:
-
obtaining a prosthetic meniscus implant manufactured from resilient polymeric material comprising; a generally semi-circular toroidal body having a first end and a second end and having a generally wedge shaped cross section whose apex generates an inferior generally arcuate edge and whose apex-opposing side forms a superior elevated generally arcuate rim said body composed of flexible and resilient material;
an elongate member, composed of flexible and resilient material, extending from each of said first and said second end of said body and terminating in a free end;
said elongate member incorporating at least one flexible and resilient co-axial anchoring protuberance positioned along the length;drilling a plurality of anchoring through-holes having a proximal open end and a distall open end in the tibia configured and positioned to allow said protuberances of said prosthetic meniscus implant to pass through holes when said elongate members are pulled through the proximal end when compressed but not allow re-passage of the protuberance once it exits said distal open end; inserting each of said elongate members through its respective said anchoring through-hole and successively compressing one or more the resilient co-axial protuberances as they pass through the respective said anchoring through-hole until said resilient co-axial protuberance exits the distall end of respective said anchoring through-hole thereby permitting said protuberance to reassume its uncompressed shape; wherein the said prosthetic meniscus implant is anchored by the said protuberances retained by the said anchoring through-holes. - View Dependent Claims (5, 6)

7. A method for selling a prosthetic meniscus implant manufactured from resilient polymeric material comprising:
-
a generally semi-circular toroidal body having a first end and a second end and having a generally wedge shaped cross section whose apex generates an inferior generally arcuate edge and whose apex-opposing side forms a superior elevated generally arcuate rim, said body composed of flexible and resilient material;
an elongate member, composed of flexible and resilient material, extending from each of said first and said second end of said body and terminating in a free end;
said elongate member incorporating at least one flexible and resilient co-axial anchoring protuberance positioned along the length;comprising the steps of; informing a medical practitioner of the benefits and availability of said prosthetic meniscus implant; instructing the said medical practitioner the method for implanting said prosthetic meniscus implant;
providing said prosthetic meniscus implant.
