No
The description focuses on mechanical and magnetic components for limb lengthening and fusion, with no mention of AI or ML algorithms for analysis, decision-making, or control.
Yes
The device is indicated for tibio-talo-calcaneal fusions, fracture fixation, pseudarthrosis, mal-unions, non-unions, and bone transport, and can be used for limb lengthening. These are all medical treatments for conditions or injuries.
No
The device is a system for tibio-talo-calcaneal fusions and limb lengthening, and its description focuses on its mechanical components and surgical applications, not on diagnosing medical conditions.
No
The device description clearly outlines hardware components including a nail, screws, end caps, and an external remote controller (ERC), all made of physical materials like titanium alloy. While the ERC might contain software, the core device is a physical implantable system.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Description: The Precice Ankle Salvage System is a surgical implant (a nail, screws, and associated instruments) used for bone fusion and limb lengthening. It is physically implanted into the patient's body.
- Intended Use: The intended use is for surgical procedures (tibio-talo-calcaneal fusions and subsequent limb lengthening), not for analyzing biological samples.
The description clearly indicates a device used in vivo (within the living body) for structural support and manipulation, not for in vitro (in glass/outside the body) diagnostic testing.
N/A
Intended Use / Indications for Use
The Precice Ankle Salvage System is indicated for tibio-talo-calcaneal fusions in adults. When used for tibio-talo-calcaneal fusion, the Precice Ankle Salvage System may be used for open and closed fracture fixation, pseudarthrosis, mal-unions, non-unions, or bone transport of long bones adjacent to the fusion site. The device may be used for subsequent limb lengthening once tibio-talo-calcaneal fusion has been achieved.

Device Description
The Precice Ankle Salvage System is a tibio-talo-calcaneal fusion system that consists of the Precice Ankle Salvage nail, locking screws, end caps, and associated general instruments. The Precice Ankle Salvage nail is compatible with an accessory External Remote Controller (ERC). The Precice Ankle Salvage nail, endcap, and locking screws are supplied sterile by gamma radiation. The Precice Ankle Salvage nail contains an enclosed rare earth magnet, telescoping distraction rod, and planetary gearing which allows the length of the nail to be adjusted non-invasively by the ERC. Retraction of the Precice Ankle Salvage nail can be utilized to maintain compression across the tibio-talo-calcaneal ioints post-operatively. The Precice Ankle Salvage nail can also be used to subsequentially correct a limb length discrepancy that may result after the tibio-talo-calcaneal fusion procedure.
The purpose of this submission is to implement material and design changes to the predicate Precice Ankle Salvage System (K200430) to create a product line extension which includes the Precice Ankle Salvage nail, end caps, and locking screws in titanium. The subject device is manufactured from medical grade Titanium alloy (Ti-6Al-4V) per ASTM F136. The Precice Ankle Salvage nail is available in various nail styles, diameters, and lengths to accommodate a variety of patient anatomies and surgeon preference. The locking screws are available in a variety of diameters, lengths, and thread styles. The ERC is available in several compatible models. These modifications do not change the indications for use or intended use of the device, nor do they change the fundamental scientific technology of the device.

C. Predicate Devices
The subject Precice Ankle Salvage System is substantially equivalent to the primary predicate device Precice Ankle Salvage System (K200430). The Precice Intramedullary Limb Lengthening System (K220234) served as an additional predicate.
D. Device Description
The Precice Ankle Salvage System is a tibio-talo-calcaneal fusion system that consists of the Precice Ankle Salvage nail, locking screws, end caps, and associated general instruments. The Precice Ankle Salvage nail is compatible with an accessory External Remote Controller (ERC). The Precice Ankle Salvage nail, endcap, and locking screws are supplied sterile by gamma radiation.

invasively by the ERC. Retraction of the Precice Ankle Salvage nail can be utilized to maintain compression across the tibio-talo-calcaneal ioints post-operatively. The Precice Ankle Salvage nail can also be used to subsequentially correct a limb length discrepancy that may result after the tibio-talo-calcaneal fusion procedure.
The purpose of this submission is to implement material and design changes to the predicate Precice Ankle Salvage System (K200430) to create a product line extension which includes the Precice Ankle Salvage nail, end caps, and locking screws in titanium. The subject device is manufactured from medical grade Titanium alloy (Ti-6Al-4V) per ASTM F136. The Precice Ankle Salvage nail is available in various nail styles, diameters, and lengths to accommodate a variety of patient anatomies and surgeon preference. The locking screws are available in a variety of diameters, lengths, and thread styles. The ERC is available in several compatible models. These modifications do not change the indications for use or intended use of the device, nor do they change the fundamental scientific technology of the device.
E. Indications for Use
The Precice Ankle Salvage System is indicated for tibio-talo-calcaneal fusions in adults. When used for tibio-talo-calcaneal fusion, the Precice Ankle Salvage System may be used for open and closed fracture fixation, pseudarthrosis, mal-unions, or bone transport of long bones adjacent to the fusion site. The device may be used for subsequent limb lengthening once tibiotalo-calcaneal fusion has been achieved.
F. Comparison of Indications for use with the Predicate Device
The Precice Ankle Salvage System has the same intended use as the predicate device Precice Ankle Salvage System (K200430). Both the subject and predicate device achieve tibio-talocalcaneal fusion by providing sustained compression across the fusion site post-operatively. The subject device indications for use differ from the predicate device Precice Ankle Salvage System (K200430) indications by specifying that it is for adults. This difference in indications does not change the intended use or fundamental scientific technology of the device so it does not affect the intended surgical use or the safety and effectiveness of the device.
Additionally, the Precice Ankle Salvage System has the same intended use as both the predicate Precice Ankle Salvage System (K200430) and Precice Intramedullary Limb Lengthening System (K220234) for fracture fixation and limb lengthening.
Therefore, the subject device does not create a new intended use.
G. Comparison of Technological Characteristics with the Predicate Device
As was established in this submission, the subject Precice Ankle Salvage System is substantially equivalent to the primary precice Ankle Salvage System (K200430), which was previously cleared by the FDA for commercial distribution in the United States. The subject device has been shown to be substantially equivalent and have equivalent technological characteristics to the predicates through comparison in areas including design, principles of operation, labeling/intended use, material composition, and function.
