Patent number: 11491017Abstract: A meniscus replacement device for replacing damaged soft tissue at a host knee includes a first component comprising a first tissue-interface surface shaped to free-floatingly interface with tissue structure of one of a femur and a tibia in a knee joint having a damaged soft tissue, and comprises a second component comprising a second tissue-interface surface shaped to free-floatingly interface with a second tissue structure of the other of the femur and the tibia in the knee joint. The second component may include a containment cavity receiving at least a portion of the first component. In another form, the free floating soft joint tissue replacement component and the base component are fixed together. In some aspects, the second tissue-interface surface is shaped to fit contours of a natural tibia plateau. In some aspects, the first tissue-interface surface is shaped to fit contours of a femoral surface.Type: GrantFiled: July 27, 2018Date of Patent: November 8, 2022Assignee: Active Implants LLCInventors: Jonathan J. Elsner, Eran Linder-Ganz, Henry A. Klyce

Patent number: 11439510Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, 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 that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.Type: GrantFiled: July 31, 2020Date of Patent: September 13, 2022Assignee: Active Implants LLCInventors: Eran Linder-Ganz, Lex R.

Patent number: 11129722Abstract: 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. Methods of implanting meniscus prosthetic devices are also disclosed.Type: GrantFiled: May 6, 2019Date of Patent: September 28, 2021Assignee: ACTIVE IMPLANTS LLCInventors: Eran Linder-Ganz, Avraham Shterling, Noam Weissberg

Patent number: 10835381Abstract: A two-part joint replacement device for replacing damaged soft joint tissue, such as a meniscus or cartilage tissue. In one form, the device may include a free floating soft joint tissue replacement component comprising a first tissue-interface surface shaped to engage a first anatomical (bone and/or cartilage) structure of a joint having damaged soft tissue. The device may also include a free floating rigid base component comprising a second tissue-interface surface shaped to engage a second anatomical (bone and/or cartilage) structure of the joint. The free floating soft joint tissue replacement component may be shaped to slidably interface with the rigid base component. In another form, the free floating soft joint tissue replacement component and the rigid base component are fixed together.Type: GrantFiled: July 27, 2018Date of Patent: November 17, 2020Assignee: Active Implants LLCInventors: Eran Linder-Ganz, Jonathan J.

Patent number: 10758358Abstract: 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: GrantFiled: August 13, 2018Date of Patent: September 1, 2020Assignee: Active Implants LLCInventors: Eran Linder-Ganz, Jacob Jonathan Elsner, Avraham Shterling
