Intended Use

The Ellipse PRECICE System is indicated for limb lengthening of the tibia and femur.

Device Story

The Ellipse PRECICE System is an intramedullary limb lengthening device consisting of a sterile nail, locking screws, and an external remote controller (ERC). The nail is implanted into the intramedullary canal of the femur or tibia and secured with locking screws. It contains an internal rare earth magnet, a telescoping lead screw/nut assembly, and planetary gearing. The device is adjusted non-invasively by the patient or clinician using the ERC, which interacts with the internal magnet to drive the telescoping mechanism, thereby lengthening the bone. This system allows for controlled, gradual limb lengthening without additional invasive procedures. The device is intended for use in clinical settings for patients undergoing orthopedic limb lengthening.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included static and dynamic four-point bend tests (ASTM F1264-03) for the nail, static and dynamic three-point bend tests (ASTM F1264-03) for locking screws, and axial pullout strength and torque-to-failure tests (ASTM F543-07) for locking screws. Device functionality and verification testing were also performed.

Technological Characteristics

Intramedullary fixation rod; rare earth magnet, telescoping lead screw/nut assembly, and planetary gearing. Materials include metallic components for intramedullary fixation. Testing performed per ASTM F1264-03 (bend/torque) and ASTM F543-07 (pullout/torque). Sterilization of nail via gamma radiation; screws/accessories supplied non-sterile. Non-invasive adjustment via external remote controller (ERC).

Indications for Use

Indicated for limb lengthening of the tibia and femur in patients requiring orthopedic reconstruction.

Regulatory Classification

Identification

An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures.

- 2. Proprietary Trade Name: Ellipse PRECICE® System
Common Name: Intramedullary Nail 3.

4. Classification Name: Intramedullary Fixation Rod (21 CFR 888.3020)

Product Code: HSB (Rod, Fixation, Intramedullary and Accessories) રો

Product Description: The Ellipse PRECICE System is composed of the PRECICE nail (supplied 6. sterile), locking screws, surgical instruments and an external remote controller (ERC). The nail is available in tibia or femur models with various diameters, lengths and screw hole configurations to accommodate a variety of patient anatomies. The locking screws are also available in a variety of diameters and lengths. The PRECICE nail is supplied sterile by gamma radiation while the locking screws and PRECICE specific accessories are supplied non-sterile and must be sterilized prior to use. The nail contains an enclosed rare earth magnet, telescoping lead screw/nut assembly, and planetary gearing.

7. Indications: The Ellipse PRECICE System is indicated for limb lengthening of the tibia and femur.

8. Substantial equivalence: Documentation that includes mechanical test results and detailed comparison to the predicate devices demonstrates that the Ellipse PRECICE System is substantially equivalent to the following 510(k) cleared device:

. Ellipse Intramedullary. Limb Lengthening System (K 131677)

{1}------------------------------------------------

and the control of the control of the control of the contribution of the contribution of the contribution of the contribution of the contribution of the contribution of the c

Substantial equivalence is based on similar indications for use, designs, and on in vitro testing performed. Where specific dimensional differences exist, bench testing has shown that these differences do not present new risks.

The 8.5 mm PRECICE Nail and the predicate device have intended use. Specifically, to lengthen the femur or tibia. The 8.5 mm diameter nail and the predicate are available in the same application, screw hole configurations, stroke lengths, and overall lengths. The 8.5 PRECICE Nail has the same materials, technological characteristics and principles of operation as that of the predicate. Both devices are inserted into the intramedullary canal of the femur or tibia and secured with locking screws. Both devices are adjusted non-invasively by the Ellipse external remote controller (ERC). The differences between the modified PRECICE System and the predicate device are as follows:

- . Addition of an 8.5 mm diameter nail which has a tapered 10.7 mm proximal end for compatibility with the 5.0 mm locking screws and implantation tools.
- . Addition of a 3.5 mm diameter locking screw, which will be used to secure the distal end of the 8.5 mm implant to the bone.

Data relied upon to determine substantial equivalence of the PRECICE System with the device modifications described in this submission to the cleared PRECICE System include the following:

- . Mechanical testing
·

- Design functionality and performance testing .
The following specific tests have been performed in order to establish equivalence to the predicate devices:

| Test Description | Applicable Test Standard . |
|-------------------------------------------------|----------------------------|
| PRECICE Nail, Static Four Point Bend | ASTM F1264-03 |
| PRECICE Nail, Dynamic Four Point Bend | ASTM F1264-03 |
| PRECICE Nail, Static Torque to Failure | ASTM F1264-03 |
| PRECICE Locking Screw, Static Three Point Bend | ASTM F1264-03 |
| PRECICE Locking Screw, Dynamic Three Point Bend | ASTM F1264-03 |
| PRECICE Locking Screw, Axial Pullout Strength | ASTM F543-07 |
| PRECICE Locking Screw, Torque to Failure | ASTM F543-07 |
| Device functionality and verification | None |

Based on the non-clinical testing performed, the 8.5 mm PRECICE Nail in this Special 510(k) is as safe, effective, and performs as well as the predicate device (K131677).
