The MEMOMETAL implants (K-Snap® & Ti-Fuse®) are indicated for fixation of bone fracture, for bone reconstruction or arthrodesis in presence of appropriate immobilization. The size of the implant should be adapted to the specific indication.
Device Story
MEMOMETAL implants (K-Snap® and Ti-Fuse®) are single-use, metallic bone fixation appliances designed for permanent implantation. K-Snap® features a snap-off pin design with a smooth shaft, stop, and sharp self-drilling tip; Ti-Fuse® features a notched design with a T-shaped head. Used by surgeons in clinical settings for bone fracture fixation, reconstruction, or arthrodesis, these devices provide mechanical stabilization of bone segments. The surgeon selects the appropriate implant size based on the specific anatomical site and clinical requirement. The device functions by providing rigid or semi-rigid fixation to support bone healing. Clinical benefit is derived from the stabilization of bone fragments, facilitating proper union during the osteosynthesis period.
Clinical Evidence
Bench testing only. Engineering rationale provided comparing mechanical properties (flexure loading) of Ti-Fuse® and K-Snap® implants against the predicate K100736. Insertion testing in cortical bone performed to verify structural integrity and prevent premature breakage.
Technological Characteristics
Metallic bone fixation fasteners. Designs include snap-off pins (smooth with stop and self-drilling tip) and notched pins with T-shaped heads. Single-use. Mechanical fixation principle. No software or electronic components.
Indications for Use
Indicated for fixation of bone fractures, bone reconstruction, or arthrodesis in patients requiring bone immobilization. Size must be adapted to specific clinical indication.
Regulatory Classification
Identification
A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.
