Publication number: 20090259312Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores shock absorption, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature. The anti-migration feature is a bridge for engagement with a femur notch in some instances. Generally, the anti-migration feature allows the artificial meniscus to be implanted into the patient's knee and maintain its position within the knee without penetrating the adjacent bone. The bridge is reinforced with fibers in some instances.Type: ApplicationFiled: April 9, 2008Publication date: October 15, 2009Applicant: ACTIVE IMPLANTS CORPORATIONInventors: Avraham Shterling, Gal Zur, Eran Linder-Ganz, Noam Weissberg

Publication number: 20090259311Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores shock absorption, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device is pre-tensioned to improve the fit of the prosthetic device within the knee joint and, thereby, maximize the contact area of the load-bearing surfaces to distribute loading through the prosthetic device in a manner substantially similar to that of a healthy natural meniscus. In some embodiments, the pre-tensioned prosthetic device is smaller, or scaled-down, relative to the size of a healthy natural meniscus.Type: ApplicationFiled: April 9, 2008Publication date: October 15, 2009Applicant: ACTIVE IMPLANTS CORPORATIONInventors: Avraham Shterling, Eran Linder-Ganz, Amir Danino
