No
The description focuses on the mechanical and electrical operation of the external remote controller for limb lengthening, with no mention of AI or ML algorithms for decision-making, image analysis, or automated adjustments beyond programmed lengthening.
Yes
The device, the PRECICE Intramedullary Limb Lengthening System, is indicated for limb lengthening of the tibia and femur, which is a therapeutic purpose.
No
The device, the PRECICE Intramedullary Limb Lengthening System, is used for limb lengthening by physically adjusting an implanted nail. While it is used in conjunction with "standard, routine x-ray" for confirmation, the device itself does not perform any diagnostic function; its role is therapeutic.
No
The device description explicitly states that the system is composed of hardware components including the PRECICE Nail, locking screws, end cap, surgical instruments, and an external remote controller (ERC 3P), which is described as an electrically powered handheld unit containing magnets and gears. While the ERC 3P has software for prescription programming and control, it is an integral part of a larger hardware system used for limb lengthening.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "limb lengthening of the tibia and femur." This is a surgical procedure involving an implanted device and an external controller to physically lengthen bone.
- Device Description: The description details an implanted nail, locking screws, surgical instruments, and an external remote controller. These are all components used in a surgical and post-surgical process directly on the patient's body.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections. This device does not involve testing samples from the body.
The device is a medical device used for a therapeutic purpose (limb lengthening), not for diagnostic testing of biological samples.

Device Description
The PRECICE Intramedullary Limb Lengthening System is composed of the PRECICE Nail (supplied sterile), locking screws, end cap, surgical instruments and an external remote controller (ERC, ERC2P, or ERC 3P). 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 surgical instruments are supplied non-sterile and must be sterilized prior to use.
The third generation External Remote Controller (ERC 3P) which is the subject of this premarket notification, is a non-invasive adjustment component of the system. The ERC 3P is an electrically powered handheld unit. The ERC 3P contains two large rare-earth magnets that are rotated using gears. After the PRECICE Nail has been implanted into the patient, the external device can be placed over the actuator portion of the nail and activated, the magnets within the ERC 3P rotate, which causes the magnet in the actuator portion of the PRECICE Nail to rotate, lengthening or shortening the nail. Periodic lengthening (typically daily) of the nail is performed after the implantation surgery to lengthen the limb. The ERC 3P also encompasses on-unit prescription programming. The distraction is confirmed in office using standard, routine x-ray of the limb. These office visits usually occur on a weekly basis. The principles of operation of the ERC 3P are the same as those of the ERC and ERC2P previously cleared.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Usability evaluation of the ERC 3P in a representative population was performed to demonstrate its suitability for use by the proposed patient population in the home environment and in accordance with the indications.
The third generation ERC for the PRECICE Intramedullary Limb Lengthening System was developed and evaluated in accordance with recognized standards and with in-house developed test methodologies. This testing includes risk assessment of the device, testing to applicable IEC standards, and a usability study undertaken on 17 participants to evaluate the usability of the ERC 3P in an equivalent patient population. Risk analysis, draft labeling, and test results are included in this premarket notification. The results of testing demonstrate that the ERC 3P for the PRECICE Intramedullary Limb Lengthening System that is the subject of this premarket notification is substantially equivalent to the predicate External Remote Controller (ERC 2P) device.
Testing includes a usability evaluation for the Home Use of the ERC 3P by the patient, minimum rated voltage testing, shock and vibration testing, and ingress protection testing performed in accordance with IEC 60601-1-11;2015. The following tests have been performed in order to establish equivalence to the predicate device:

The purpose of this premarket notification is to include a third generation External Remote Controller (ERC 3P) into the PRECICE® Intramedullary Limb Lengthening System. Data provided in this submission includes information relevant to the third generation ERC (ERC 3P). Substantial equivalence is based on similar indications for use, designs, in vitro testing, software validation, and Usability and labeling readability evaluations performed. The in vitro evaluations included specific tests performed on the ERC 3P to demonstrate the suitability of the device for its intended use, and electrical safety and electromagnetic compatibility tests. Usability evaluation of the ERC 3P in a representative population was performed to demonstrate its suitability for use by the proposed patient population in the home environment and in accordance with the indications.
The ERC 3P was designed to improve ergonomic handling and user interfaces, and has the same methods and principles of operation as the first and second generation ERCs. The ERC 3P incorporates an updated user interface and combines the controller and hand piece into one unit, to be more ergonomic and user friendly. The ERC 3P incorporates an updated user interface that utilizes an LCD touchscreen, camera, external magnet line to assist the patient in proper alignment with the implant location, as well as features to detect the pairing status of the ERC 3P with the implanted PRECICE Nail during lengthening sessions. The third generation ERC for the PRECICE Intramedullary Limb Lengthening System was developed and evaluated in accordance with recognized standards and with in-house developed test methodologies. This testing includes risk assessment of the device, testing to applicable IEC standards, and a usability study undertaken on 17 participants to evaluate the usability of the ERC 3P in an equivalent patient population. Risk analysis, draft labeling, and test results are included in this premarket notification. The results of
