The description focuses on the mechanical and ultrasonic functions of the device for tissue fragmentation and aspiration, with no mention of AI or ML capabilities.
No.
The device is used for surgical procedures to fragment, emulsify, and aspirate soft tissue, which is an intervention, not a therapeutic treatment.
No
The provided text describes the Tenex Health TX System as an ultrasonic surgical aspirator used for fragmenting, emulsifying, and aspirating soft tissue during surgical procedures. There is no mention of it being used to diagnose conditions or diseases.
No
The device description clearly outlines multiple hardware components including a console, ultrasonic handpiece, inflation cuff, and foot pedal, in addition to the software interface.
Based on the provided information, the Tenex Health TX System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states the device is for "surgical procedures where fragmentation, emulsification and aspiration of soft tissue are desirable." This describes a surgical tool used directly on the patient's tissue during a procedure.
- Device Description: The description details a system that physically interacts with tissue (fragmenting, emulsifying, aspirating) using ultrasonic energy, irrigation, and aspiration. This is characteristic of a surgical device.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, tissue samples) outside of the body to provide information about a patient's health status, which is the core function of an IVD.
In summary, the Tenex Health TX System is a surgical device used for tissue removal during procedures, not a device used for testing samples in a laboratory setting.

Intended Use / Indications for Use

Device Description
The Tenex Health TX System is an ultrasonic surgical aspirator that fragments, emulsifies and removes soft tissue. The system consists of a console, ultrasonic handpiece, inflation cuff and foot pedal. The console provides control over the user functions including irrigation, aspiration, and ultrasonic fragmentation/emulsification. It has a large, color LCD and employs a touch-screen with a graphical user interface for selection of required settings. The console provides audible tones for confirmation of selections. The console also houses the irrigation valve, the irrigation pump, and the aspiration pump, thereby eliminating the need for a dedicated service cart or suction/waste source within the operating room.
The ultrasonic handpiece connects to the console for power, as well as for delivering irrigation fluid directly to the surgical site and for aspirating emulsified tissue by way of integrated tubing set. The handpiece is constructed from various polymers and metals, while the tubing is made of biomedical grade PVC. The handpiece and tubing are provided sterile. The handpiece and tubing are a single use disposable component of the system. Irrigation fluid is delivered under pressure to the surgical site by operation of an air pump residing in the console. The regulated output of the air pump pressurizes an inflation cuff that is filled around the irrigating fluid bag, thus providing irrigation at a fixed pressure.
The foot pedal is used to control each of the functions (irrigation, aspiration, ultrasonic fragmentation/emulsification) of the system. It offers on/off functionality and is rated IPX8 (by the supplier) for protection against liquids.

807.92(b)(3) – Conclusions drawn from non-clinical and clinical data
By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device.
lt has been shown in this 510(k) submission that the difference between the Tenex Health TX System and the predicate device, the TX1 Tissue Removal System, does not raise any questions regarding its safety and effectiveness. The Tenex Health TX System, as designed and manufactured, is determined to be substantially equivalent to the referenced predicate devices.
