Patent number: 10543096Abstract: 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: GrantFiled: June 12, 2014Date of Patent: January 28, 2020Assignee: Active Implants CorporationInventors: Eran Linder-Ganz, Avraham Shterling, Amir Danino

Publication number: 20140249627Abstract: Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. In some instances, the during-implantation selection method includes monitoring loads and/or pressures applied to the prosthetic device and/or the adjacent anatomy. In some instances, the loads and/or pressures are monitored by a trial prosthetic device comprising one or more sensors. Methods of implanting meniscus prosthetic devices are also disclosed.Type: ApplicationFiled: May 12, 2014Publication date: September 4, 2014Applicant: Active Implants CorporationInventors: Eran Linder-Ganz, Jonathan Elsner, Avraham Shterling
