Intended Use

The Mbrace Cable is designed as a cerclage system for long bones and to reattach the greater trochanter in case of fractures or osteotomies. The device is intended for long-term implantation inside the human body for single use only. The Mbrace Cable is not intended for use as a suture cable in soft tissue approximation and/or ligation.

Device Story

Mbrace Cable is an implantable, flexible, braided cerclage system for orthopedic bone fixation. Device consists of UHMWPE material; used to secure long bones or reattach greater trochanter following fractures or osteotomies. Implanted by surgeons during orthopedic procedures; provides mechanical stabilization of bone segments. Device is single-use, sterile, and intended for long-term implantation. Performance validated via quasi-static load-to-failure testing and dynamic resistance testing (1 million cycles).

Clinical Evidence

No clinical studies were conducted. Evidence is based on non-clinical bench testing, including design validation via sawbone workshop, quasi-static load-to-failure testing, dynamic resistance testing (1 million cycles), pyrogenicity testing (LAL and USP <151>), biocompatibility assessment, and shelf-life evaluation.

Technological Characteristics

Implantable flexible braided cable made of UHMWPE. Sterilized via ETO. Designed for long-term bone fixation. Mechanical properties validated for quasi-static strength and dynamic endurance (1 million cycles).

Indications for Use

Indicated for cerclage fixation of long bones and reattachment of the greater trochanter in cases of fractures or osteotomies. Not for soft tissue approximation or ligation.

Regulatory Classification

Identification

A bone fixation cerclage is a device intended to be implanted that is made of alloys, such as cobalt-chromium-molybdenum, and that consists of a metallic ribbon or flat sheet or a wire. The device is wrapped around the shaft of a long bone, anchored to the bone with wire or screws, and used in the fixation of fractures.

Dear Christopher Lussier:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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 (the Act) that do not require approval of a premarket approval application (PMA). 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.

| Classification Name: | Bone fixation cerclage |
| Primary Product Code | JDQ |
| Regulation Number: | 21 CFR 888.3010 |
| Device Classification | II |

#### III. Predicate Device

Substantial equivalence is claimed to the following predicate devices.

Primary Predicate device:

Titanium alloy Songer cable system, K920201, SOFAMOR DANEK MFG., Inc. ●

Additional Predicate device:

- HS Fiber, K10006, Riverpoint Medical ●
#### IV. Device Description

The Mbrace cable is an implantable flexible braided cable made of UHMWPE and designed as a cerclage bone system.

The Mbrace cable is provided individually packed, sterile and single-use.

#### Indications for Use V.

The Mbrace Cable is designed as a cerclage system for long bones and to reattach the greater trochanter in case of fractures or osteotomies. The device is intended for long-term implantation inside the human body for single use only. The Mbrace Cable is not intended for use as a suture cable in soft tissue approximation and/or ligation.

{5}------------------------------------------------

#### VI. Comparison of Technological Characteristics

The subject Mbrace cable and the predicate Titanium alloy Songer cable system (K920201) are substantially equivalent with respect to the following characteristics:

- General design;
- Biocompatibility;
- Device usage; and
- Packaging. ●

The subject Mbrace cable is technologically different from the predicate Titanium alloy Songer cable system (K920201) as follows:

- Diameter and fixation:
- Material: and
- Sterilization. ●

### Discussion

The different diameter and fixation method of the subject Mbrace cable with respect to the predicate Titanium alloy Songer cable system (K920201), as well as the different material, do not raise any new issue related to safety and effectiveness as demonstrated by the results of the mechanical test. The different sterilization method between the subject and the predicate devices is due to the different materials, but it has not any impact on device's safety and effectiveness since the ETO sterilization method of the subject device is fully validated. The subject Mbrace cable, in its final form, is identical to the additional predicate (HS Fiber, K100006) with regards to materials of construction, processing, geometry, sterilization method and shelf-life, thus the biocompatibility of the subject and additional predicate device can be considered the same even if the subject device is intended to be used in long bones and greater trochanter, while the additional predicate is intended for use in soft tissues.

The comparison of technological characteristics and performance data provided within the submission supports the substantial equivalence of the subject device respect to the predicate devices.

#### VII. Performance Data

Based on the risk analysis, testing activities were conducted to written protocols. The following validations and tests are provided in support of the substantial equivalence determination:

### Non-Clinical Studies

- DESIGN VALIDATION
