Intended Use

The Ellipse Intramedullary Limb Lengthening System is indicated for limb lengthening of the tibia and femurs.

Device Story

System comprises modular implantable intramedullary rod (distracting rod), locking screws, and external remote controller (ERC). Rod contains rare earth magnet, telescoping lead screw/nut assembly, and gearing. Implanted into medullary canal of femur or tibia; secured with locking screws. Non-invasive lengthening achieved via interaction between internal magnet and external remote controller; allows for both distraction and shortening. Used by surgeons in clinical setting; ERC operated to control distraction amount and direction. Benefits include precise, non-invasive adjustment of limb length compared to manual mechanical rotation systems.

Clinical Evidence

Bench testing only. Testing included sterilization validation (ISO 11137-2), shelf life (ISO 11607), biocompatibility (ISO 10993-1), electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and mechanical performance (ASTM F1264-03, F543-07).

Technological Characteristics

Telescoping Titanium alloy rod; rare earth magnet actuator; locking screws. Dimensions vary to accommodate anatomy. Energy source: magnetic field from external remote controller. Sterilization: Gamma radiation (actuator), non-sterile (rods/screws). Standards: ASTM F1264-03 (intramedullary rods), ASTM F543-07 (bone screws), ISO 10993-1 (biocompatibility), IEC 60601-1 (electrical safety).

Indications for Use

Indicated for limb lengthening of the tibia and femurs in patients requiring such procedures.

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.

Company: 13844 Alton Parkway, Suite 130 Irvine, CA 92618 Contact: John McIntyre Vice President, RA/QA/CA - Proprietary Trade Name: Ellipse Intramedullary Limb Lengthening System 2. - Classification Name: 21 CFR 888.3020 -- Intramedullary fixation rod 3. - Product Code: HSB Rod, Fixation, Intramedullary and Accessories 4. - Product Description: 5. , j The Ellipse Intramedullary Limb Lengthening System is composed of a modular implantable intramedullary rod ("Distracting Rod"), locking screws, an external remote controller (ERC), and implantation tools and accessories. The modular implantable rod is available in different configurations, lengths, and diameters to accommodate a variety of patient anatomies. Likewise, the locking screws are available in two different diameters and a variety of lengths from 20 mm to 75 mm in 5 mm increments. The distracting rod is a modular system that includes the IMLL Actuator component and various configurations of IMLL Extension Rods. The IMLL Actuator includes an enclosed rare earth magnet, telescoping lead screw/nut assembly and gearing. The IMLL Actuator is supplied sterile by gamma sterilization while the IMLL Extension Rods, locking screws, and reusable accessories are supplied non-sterile and must be sterilized prior to use. #### 6.

Ellipse Intramedullary Limb Lengthening SystemProduct Code: HSB Original 510(k) Application ### Substantial equivalence 7. . Documentation that includes mechanical test results and detailed comparison to the predicate device demonstrates that the Ellipse Intramedullary Limb Lengthening System is substantially equivalent to the Orthodyne/Orthofix ISKD device (K010322 and K031219). Substantial equivalence is based on similar indications for use, designs, and on in vitro testing performed. The Ellipse IMLL System and the predicate device have similar technological characteristics. Specifically, the Ellipse IMLL System and the predicate devices are both designed to be implanted into the medullary canal of the femur or tibia. These devices are available in a variety of geometrical configurations and diameters/lengths to accommodate a variety of patient anatomies. Both devices are designed as a telescoping rod that can be lengthened non-invasively. The ISKD device is lengthened by manual mechanical rotation of the limb while the Ellipse IMLL system is lengthened by the interaction of the rare earth magnet which is contained within the actuator portion of the rod and the external remote controller. The Ellipse IMLL system has the advantage that the length of the rod can be shortened if the rod has been distracted too much. The ISKD device can only be adjusted in one direction (i.e., distraction). Furthermore, the Ellipse IMLL and the ISKD device have a number of common design features, such as a telescoping Titanium alloy rod that is attached proximally and distally using locking screws. Both devices have telescoping features that are adjustable non-invasively. The Ellipse IMLL gives the user a better level of control of the distraction amount and direction, however. The Ellipse IMLL device and the predicate device feature similar overall shapes. The various configurations and dimensions are available to accommodate the variety of patient anatomies encountered in limb lengthening procedures. Testing included sterilization, shelf life testing for the packaging and the device functionality, biocompatibility testing, and testing to ASTM F1264-03 for intramedullary rods and F543-07 for metallic medical bone screws. Additional testing to demonstrate the safety of the magnetic fields from both the rare earth magnet included in the IMLL Actuator as well as the External Remote Controller demonstrated that the induced magnetic fields are below established Confidential - This document and the information contained herein may not be reproduced, used or disclosed without written permission from Ellipse Technologies, Inc. {2}------------------------------------------------ K101997 June 2010 p313 ### Ellipse Technologies, Inc.
