It is indicated for cystourethropexy and vaginal sling procedures for the treatment of stress type (female) urinary incontinence resulting from urethral hypermobility and/or intrinsic sphincter deficiency. ## Device Story MicroTac Bone Anchor System facilitates soft tissue fixation to pubic bone; utilizes bone anchors threaded with sutures. System comprises bone anchors and manual, single-use inserter. Used by surgeons in clinical settings for cystourethropexy and vaginal sling procedures. Device provides mechanical fixation of soft tissue to bone to treat stress urinary incontinence. Replaces spring-loaded, multi-use inserter mechanism of predicate device with manual delivery system. Performance testing confirms equivalence in fixation strength and safety profile. ## Clinical Evidence Bench testing only; no clinical data provided. Performance testing demonstrated equivalence to the predicate device. ## Technological Characteristics System includes bone anchors and manual inserter. Single-use design. Materials and performance characteristics are equivalent to the predicate In-Tac system. No specific ASTM standards or software components described. ## Regulatory 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. ## Predicate Devices - In-Tac Bone Anchor System ([K964953](/device/K964953.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Inc.'s MicroTac Bone Anchor System 510(k) Number K99D160 This 510(k) notification is submitted by Influence, Inc., 71 Stevenson Street, Suite 1120, San Francisco, California 94105. The contact person is Peter Bick, M.D., President and CEO. This 510(k) notification describes a device intended for soft tissue fixation to the pubic bone by means of bone anchors threaded with sutures. It is indicated for cystourethropexy and vaginal sling procedures for the treatment of stress type (female) urinary incontinence resulting from urethral hypermobility and/or intrinsic sphincter deficiency. The MicroTac Bone Anchor System is substantially equivalent to Influence, Inc.'s In-Tac Bone Anchor System cleared under K964953 with respect to intended use, materials and performance of the bone anchors. The major differences between the two systems are that the inserter of the MicroTac Bone Anchor System is designed for single use and is manual, while the predicate device is designed for multiple use and uses springs to deliver energy to the bone anchors. Information on risk analysis of the modifications and performance testing provided in the application demonstrates equivalence to the predicate device with respect to performance. Based on the performance data gathered, the device modifications do not raise any new questions of safety or effectiveness. Based on the information provided the MicroTac Bone Anchor System is substantially equivalent to the In-Tac Bone Anchor System with respect to intended use, technological characteristics, and performance. {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
