Device Description

The OSSIOfiber® Suture Anchor consists of an eyelet and anchor body preloaded on an inserter. The anchor body and eyelet are made from poly (L-lactide-co-D,L-lactide) (PLDLA) reinforced with continuous mineral fibers. OSSIOfiber® implants have been shown to be biocompatible. The polymer content degrades by hydrolysis into alpha-hydroxy acids that are metabolized by the body. The fibers are made from minerals that are found in natural bone. As the OSSIOfiber® implants degrade, the load transfers to the surrounding anatomy throughout the healing period of the bone. Substantial degradation takes place within approximately 18 months as shown in pre-clinical studies, thus eliminating the requirement for future hardware removal surgery. Sutures, needles and suture snare may also be provided with the device depending on configuration.

The OSSIOfiber® Suture Anchors are sterile, single-use, and non-pyrogenic.

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Summary of Technological Characteristics

The OSSIOfiber® Suture Anchors have identical intended use, material composition, design characteristics, principles of operation, manufacturing and sterilization methods (sterilized by EtO), and similar indications for use as their predicate device (K251309). The OSSIOfiber® subject device include indications for use in pediatric patients, which are not present in the predicate device (K251309). The devices are available in sizes appropriate for the children and adolescents patient population. The difference in the identified patient population does not alter the intended use, as the design, materials, and performance characteristics are appropriate for both adult and pediatric applications. Thus, any differences between the subject devices and their predicates do not raise different questions of safety and effectiveness.

Non-Clinical Data

Biocompatibility for the subject device was established within the predicate clearance (K251309). Biocompatibility for the additional children and adolescents patient population was established primarily based on the referenced ISO 10993 data from the previously cleared reference devices (K231272, K243760, K252022) as well as a rationale. Additional mechanical performance testing

K254055

was not performed as the indications for use of the subject device do not present a new worst case compared to the cleared OSSIOfiber® predicate.

Conclusions

The OSSIOfiber® Suture Anchor has identical intended use, material composition, design characteristics, principles of operation, manufacturing and sterilization methods (sterilized by EtO), and similar indications for use as its predicate device (K251309). The addition of children and adolescents patients to the indications for use raises no new issues of safety or effectiveness. The subject devices are available in sizes appropriate for the children and adolescents patient population. The subject devices have identical intended use, material composition, principles of operation, manufacturing and sterilization methods (sterilized by EtO), and similar indications for use including the children and adolescents patient population, as their reference devices (K243760, K252022). The addition of children and adolescents patients to the indications for use does not affect safety and effectiveness when used as labeled. Thus, OSSIOfiber® Suture Anchor is substantially equivalent to its predicate devices.

Regulation Number and Section

§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.

(a)
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.(b)
Classification. Class II.
