The U.S. FDA has granted de novo authorization to Moximed Inc. for its Misha knee system, a first-of-its-kind implantable shock absorber for people suffering from osteoarthritis (OA) of the knee. The device is intended to relieve pain and improve daily function in patients ineligible for, or not ready to undergo, joint replacement.

Moximed Inc. has received $40 million in series C financing to pursue regulatory approval for its implantable shock absorber (ISA) for knee osteoarthritis (OA). Fremont, Calif.-based Moximed secured backing from investors including Advent Life Sciences, New Enterprise Associates, Future Fund, Vertex Healthcare and Runway Growth Capital to advance the Misha knee system. The company is touting the technology as the world’s first implantable shock absorber for OA.
