Device Story

Absorbable bone anchor for soft tissue-to-bone fixation; cylindrical/conical shape (0.44" x 0.11"); molded from Poly-lactiac (PLA). Used in orthopedic surgery (shoulder, knee, ankle) by surgeons to secure USP #2 sutures below bone surface. Device inserted into predrilled bone hole; toggle mechanism locks suture in place. Provides temporary fixation during tissue healing/rehabilitation. Benefits include secure attachment of ligaments/tendons to bone using absorbable material.

Clinical Evidence

Bench testing only. Pull tests performed in cadaver bone; average failure load of 32 pounds.

Technological Characteristics

Material: Poly-lactiac (PLA). Form factor: Cylindrical/conical anchor, 0.44" length x 0.11" diameter. Fixation principle: Toggle mechanism for suture locking in predrilled bone hole.

Indications for Use

Indicated for patients requiring soft tissue to bone fixation in shoulder (rotator cuff, capsule shift), knee (ligament/tendon repairs, ITB tenodesis), and ankle (Achilles tendon repair) procedures.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

COMPARISON TO PREDICATE DEVICE

The Mitek Absorbable Toggle Anchor is similar to the Mitek Stealth and Wedge Anchor in materials and to all other Mitek Anchors in use and function, i.e., to "hold" tissue, with sutures that are locked into a predrilled bone hole, for a period of rehabilitation.

DESCRIPTION OF NON CLINICAL TESTS

Mitek Absorbable Toggle Anchor pull tests from cadaver bone provided an average failure load of 32 pounds.
