Device Story

BioPro HBS is a cannulated, headless metallic bone fixation screw; used for hand, foot, and small bone fragment repairs, fusions, and osteotomies. Device is manufactured from titanium (ASTM F136-02a) with a Torx driving head. Available in 2.5mm and 3.0mm diameters with lengths ranging from 6mm to 40mm. Provided sterile via ethylene oxide (EtO) sterilization in a double blister peelable Tyvek packaging system. Intended for use by orthopedic surgeons in clinical settings to provide internal fixation of bone fragments. Output is mechanical stabilization of bone; aids in healing of fractures and fusions. Benefits include biocompatible material and secure fixation for small bone applications.

Clinical Evidence

Bench testing only. Engineering rationale provided regarding ASTM F-543 (Standard Specification and Test Methods for Metallic Medical Bone Screw) to support mechanical integrity. Sterilization and packaging validated per ANSI/AAMI ST 27-1988 and ISO 10933-7.

Technological Characteristics

Cannulated bone screw; material: titanium (ASTM F136-02a); drive type: Torx; diameters: 2.5mm and 3.0mm; lengths: 6mm-40mm; sterilization: Ethylene oxide (EtO) per ANSI/AAMI ST 27-1988; packaging: double blister with Tyvek backing.

Indications for Use

Indicated for fixation of bone fractures, non-unions, and osteotomies in the hand, foot, and small bones, including scaphoid, lunate, capitate, trapezial, metacarpal, metatarsal, phalangeal, radial head, ulnar styloid, humeral head, glenoid, malleolar, and patellar fractures, as well as small joint, intercarpal, and tarsal fusions. Contraindicated in patients with comminuted bone surfaces, pathologic bone conditions like osteopenia, or metal sensitivity.

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.

## Original unmodified predicate device:

The original unmodified device was known as the HBS. The device was submitted under 510k 020791. The device was submitted by Millennium Medical Technologies, Inc. and was distributed by them. BioPro has obtained the rights to the 510k and has been legally marketing the device since 2008.

#### Description:

The BioPro HBS screw is designed for hand, foot and small bone fragment repairs or fusions. Uses include osteotomy fixation, joint arthrodesis or post traumatic fragment repair. The BioPro HBS screw is made of titanium in compliance with ASTM F136-02a. Titanium is a biocompatible material that is readily available and commonly used in implanted medical devices. The screw is similar to other screws available on the market. The HBS screw is cannulated and comes in two diameters, 2.5mm and 3.0mm. Each screw is available in several lengths ranging from 6mm up to 40mm in length the original system was available up to 30mm lengths and the original screws

{2}------------------------------------------------

were provided non sterile. The new versions of the screw will be provided sterile. The screws have a Torx driving head.

## Summary of modifications:

The original screws were provided non-sterile and were available in two diameters, 2.5mm and 3.0mm with lengths up to 30mm

The modified screws in this submission will now be provided sterile and the lengths will increase to 40mm with no changes to the diameter of the screw.

Performance testing: The implant is made of titanium to the ASTM standards that are recognized consensus standards of the FDA. There is an ASTM standard F-543 entitled: "Standard Specification and Test Methods for Metallic Medical Bone Screw" An engineering rational is included in this submission in regards to this specification.

## Contraindications:

- 1. Comminuted bone surface that would mitigate against screw placement.
- 2. Pathologic conditions of bone such as osteopenia which would impair the ability to securely fix the staple.
- 3. Foreign body sensitivity to metals specifically titanium. Where material sensitivity is suspected, appropriate tests should be made prior to implantation.

#### Materials:

Titanium (ASTM F136-02a)

### Packaging/Sterilization Information:

The packaging will consist of a double blister system; both blisters will use a tyvek backing and a polyethylene tray. A "peel" type opening will allow reliable removal of the product inside the sterile field. This packaging will be certified and tested according to current medical packaging requirements. All components will be sterilized using the ethylene oxide gas sterilization method and validated per ANSI/AAMI ST 27-1988 prior to marketing the device. See section 14 for sterilization validation information. With an SAL of 10 .

{4}------------------------------------------------

## Labeling

Draft labeling for this device is included.

### Verification Activities

Engineering rational provided for testing of the screws. No changes were made to the diameters so there would be no changes to the torsional strength. A complete summary of the studies as they relate to the sterilization are included in Attachment "B". of the submission. Also included is the complete risk analysis for the sterilization and packaging in Attachment "A". Based on these studies we believe the subject device is safe and affective

## Conclusion:

The primary change for this special 510k submission was the change for non-sterile screws to sterile screws. The design of the screw is unchanged from our predicate device with the exception of the length increase of 10mm. Not only are the original sizes substantially equivalent to our existing device, they are identical in design and have not changed. The additional lengths were added and the 510k 991197 was used as the predicate for those changes. Considering that the design has not changed and the parts are now sterile we believe that we have shown the device to be substantially equivalent to the predicate devices.
