Device inputs include data from angular and force sensors; processed by onboard electronics to control a servo-assisted hydraulic damper (MPC damper). Output is mechanical resistance/damping adjustment to facilitate gait. Operated by patient; used in daily living. Benefits include improved mobility and stability during ambulation. ## Clinical Evidence No clinical data provided; substantial equivalence based on technological characteristics and design comparison to the predicate device. ## Technological Characteristics External prosthetic knee component; includes pyramidal head, angular sensor, force sensor, servo-assisted hydraulic damper (MPC), removable battery, and carbon fiber shell. Attaches to standard 30mm diameter tube. Electronic control system for hydraulic damping. ## Regulatory Identification An external limb prosthetic component is a device intended for medical purposes that, when put together with other appropriate components, constitutes a total prosthesis. Examples of external limb prosthetic components include the following: Ankle, foot, hip, knee, and socket components; mechanical or powered hand, hook, wrist unit, elbow joint, and shoulder joint components; and cable and prosthesis suction valves. ## Predicate Devices - C-Leg (3C100) ([K991590](/device/K991590.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Date Cleared: July 8, 1999 {1}------------------------------------------------ ### D. Description of the Device The Rel-k is an artificial limb prosthesis indicated for individuals that have undergone a trans-femoral amputation. The Rel-k is intended to replace a missing or deformed limb and functions in both normal/standing (static) and dynamic walking. The Rel-k consists of: - . Pyramidal Head - Angular Sensor . - . Force sensor - . Servo assisted Hydraulic Damper (MPC damper) - Removable Battery and electronics compartment . - Carbon Fiber Shell (outer casing) � - . Attachment for a standard 30mm diameter tube. ### E. Intended Use Statement The Rel-k is prosthetic knee, important element of a lower limb prosthesis, a medical device that is used to replace a missing or deformed limb in both static and dynamic deambulation functions. #### F. Technological Characteristics Summary The Rel-k is substantially equivalent to the Otto Bock C-Leg (C100), a Class I Exempt Device per 21CFR Part 890.3420. Differences that exist between the Rel-k and the C-Leg (C100) devices related to the technical specifications, physical appearance and design does not raise new questions of safety and effectiveness; and demonstrates that the Rel-k device is at least as safe and effective as the legally marketed Otto Bock C-Leg (C100) device. {2}------------------------------------------------ ### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
