More Information

No
The description focuses on the mechanical and ultrasonic functions of the device, with no mention of AI or ML capabilities.

Yes
The device is indicated for use in surgical procedures, debridement of wounds, and provides sharp debridement of soft and hard tissue in wounds, which directly treats medical conditions.

No

Explanation: The device is an ultrasonic surgical instrument used for fragmentation, emulsification, and aspiration of tissue, as well as debridement of wounds. It performs therapeutic procedures rather than diagnosing conditions.

No

The device description clearly outlines multiple hardware components including a console, ultrasonic MicroTip, inflation cuff, foot pedal, and supply kit. While the console has a graphical user interface, the device is not solely software.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use describes a surgical instrument used for fragmentation, emulsification, aspiration, and debridement of tissue during surgical procedures and wound treatment. This is a therapeutic and surgical intervention, not a diagnostic test performed on samples in vitro (outside the body).
  • Device Description: The description details a system that physically interacts with tissue within the body (or on a wound) using ultrasonic energy and aspiration. It's a surgical tool.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) to diagnose a condition, monitor a disease, or determine a patient's health status.
  • Performance Studies: The performance studies focus on the device's ability to fragment, emulsify, aspirate, and debride tissue, as well as its safety and usability in a surgical context. These are not studies related to diagnostic accuracy or performance.

In summary, the Tenex Health TX System with the TXP MicroTip is a surgical device used for tissue manipulation and removal, not for performing diagnostic tests on biological samples.

The Tenex Health TX System with the TXP MicroTip has the same Indications for Use as the predicate Ultrasonic Surgical Aspirator System FS1000RF (K062471) for the fragmentation, emulsification, and aspiration of soft and hard (e.g.: bone) tissue in general surgery, orthopedic surgery, laparoscopic surgery and plastic and reconstructive surgeries.

The Tenex Health TX System with the TXP MicroTip has the same Indications for Use as the predicate AUSS-6 Ultrasonic Surgical Aspirator System and Accessories (K050776) for both the fragmentation. emulsification, and aspiration of soft and hard (e.g.: bone) tissue in general surgery, orthopedic surgery, laparoscopic surgery and plastic and reconstructive surgeries; and for the debridement of wounds, such as diabetic ulcers, in application, in which, in the physician's judgement would require the use of an ultrasonic aspirator with sharp debridement. This Indication is a specific application of the same device performance to treat soft and hard tissue pathology. Simulated clinical use testing in this submission demonstrates the Tenex Health TX System with the TXP MicroTip to be safe and effective in this Indication.

Technical Characteristics (Compared to Predicate):

The subject and predicate devices are ultrasonic surgical instruments that use electrical energy in the ultrasonic frequency range to drive an applicator needle for the fragmentation and emulsification of diseased tissue. The systems use irrigation with the needle at the treatment site to emulsify the fragmented tissue. The systems also use aspiration to remove the fragmented and emulsified material from the treatment site.

    1. Simulated use testing in cadaver validated the system's design, usability and surgical technique.

Simulated use testing involved use of the device in a simulated surgical setting with cadaveric evaluation by three surgeon advisors. Testing validated the instruction steps in the product labeling, usability (human factors) and the effectiveness of the system in sharp debridement of soft and hard tissue in wounds, such as diabetic foot ulcers.

    1. Simulated use testing in bovine tissue validated the system's durability and ability to cut, fragment, emulsify and aspirate tissue as effectively as the predicate device. Testing also quantified the tissue removal rates in both soft and hard tissue.
      The testing involved multiple sample devices, both soft and hard bovine tissue media, actuation of all system functions (fragmentation/ emulsification, irrigation and aspiration), performance at each power setting (low, medium and high) and extended use of the device. Testing demonstrated the effectiveness of all system functions at all settings for performance in both soft and hard tissue, and provided quantitative data for tissue removal rates in soft and hard tissue.

Conclusions:

The Tenex Health TX System with the TXP MicroTip met all specified performance requirements. The non-clinical data, including the simulated use testing results, support the safety of the Tenex Health TX System with the TXP MicroTip, and demonstrate that it should perform as intended in the specified use conditions. Evaluation did not raise any new questions regarding safety and effectiveness. The Tenex Health TX System with the TXP MicroTip is determined to be substantially equivalent to the predicate devices.
