Intended Use

The Phantom Sof-Thread Soft Tissue Interference Screw is intended to be used to provide interference fixation of soft tissue grafts in ACL reconstruction.

Device Story

Resorbable, cannulated interference screw; used for soft tissue graft fixation in ACL reconstruction. Features widely spaced, rounded threads and conical tip; available in 7-10mm diameters and 25mm length. Material: PLLA. Operated by orthopedic surgeons in clinical/OR settings. Provides mechanical interference fixation to secure grafts within bone tunnels. Benefits patient by facilitating stable graft healing in ACL repair.

Clinical Evidence

No clinical data. Bench testing in cadaver bone performed to compare insertion torque and pull-out strength against the Linvatec BioScrew predicate.

Technological Characteristics

Resorbable, cannulated interference screw; material: PLLA; dimensions: 7, 8, 9, 10mm diameters, 25mm length; design features widely spaced, rounded threads and conical tip.

Indications for Use

Indicated for patients undergoing ACL reconstruction requiring interference fixation of soft tissue grafts.

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.

## DEVICE DESCRIPTION AND INTENDED USE:

The Phantom Sof-Thread Screw is a resorbable, cannulated, interference screw with widely spaced, rounded threads and a conical tip, designed for use with soft tissue grafts. The Sof-Thread Screw is available in 4 diameters, 7. 8, 9 and 10mm, and one length, 25mm. The Phantom Sof-Thread Screw is intended to be used to provide interference fixation of soft tissue grafts in ACL reconstruction.

K960652

## BASIS OF SUBSTANTIAL EQUIVALENCE:

The Hyloc Interference Screw (now called the Phantom Interference Screw) is a resorbable, cannulated or non-cannulated interference screw, manufactured from the same material as the Phantom Sof-Thread Screw (PLLA), available in diameters of 7, 8 and 9mm and in lengths of 15-30mm. It is intended to be used to provide interference fixation of the bone block in bonetendon-bone grafts used for ACL reconstruction. The major differences in design between the Phantom Sof-Thread Screw and the Phantom Interference Screw are the more rounded and widely spaced threads, the rounded edges on the driver end and the one larger diameter size of the Phantom Sof-Thread Screw.

The Linvatec BioScrew Absorbable Interference Screw is a resorbable, cannulated interference screw available in diameters of 7-9mm and lengths of 20-30mm. The BioScrew is manufactured from PLLA and is intended "to provide interference fixation of patellar bone-tendon-bone grafts in ACL reconstruction and for femoral and/or tibial fixation in ACL reconstruction using a soft tissue graft (semitendinous, gracilis)".

Mechanical testing in cadaver bone has shown that the average insertion torque and pull-out strength of the Phantom Sof-Thread Screw are comparable to those of the Linvatec BioScrew.

Dear Ms. Hastings:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory ... 124 mm 17 action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
