Patent number: 11957592Abstract: 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: September 12, 2022Date of Patent: April 16, 2024Inventors: Eran Linder-Ganz, Lex R.

Patent number: 8221405Abstract: A medical system and device for use in delivering RF energy to a tissue opening and a method for determining an RF dose is disclosed. In one embodiment, the medical device includes an electrode or anchor and one or more devices, such as an impedance electrode, RF electrode and/or thermocouple. The electrode or anchor can be deployed from a delivery shaft inside the left atrium, for example, of a heart and substantially conform to the tissue proximate the tissue opening. Tissue characteristics, such as temperature and/or impedance, can be measured, before, during and after application of RF energy to the tissue, by one or more devices to determine an RF dose. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.Type: GrantFiled: February 5, 2007Date of Patent: July 17, 2012Assignee: Coherex Medical, Inc.Inventors: Brian K.
