### Device Description:

The Tenex Health TX System with the TXP MicroTip is an ultrasonic surgical instrument that fragments, emulsifies and aspirates soft and hard tissue. It also provides sharp debridement of soft and hard tissue in wounds such as neuropathic ulcers. The Tenex Health TX System with the TXP MicroTip is intended for use in an office-based setting, clinical environment or hospital environment. The system consists of a console, ultrasonic MicroTip, inflation cuff, foot pedal and supply kit. The console provides power and control for 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

{4}------------------------------------------------

selections. The console also houses the irrigation valve, the irrigation pump and the aspiration pump. The Console is non-sterile when used and does not require processing.

The ultrasonic MicroTip connects to the console for electrical power, the transfer of irrigation fluid to the surgical site and the aspiration of emulsified tissue back to the collection bag. The MicroTip is single use, sterile packaged. A single use, disposable collection bag is integrated into the MicroTip tubing to collect the aspirated materials. The connections are made via an integrated wiring connector and tubing set. The handpiece is constructed from various biocompatible polymers and metals. The tubing is made of biomedical grade PVC. The handpiece and tubing are provided sterile, via electron beam irradiation. The handpiece and tubing are a single use disposable component of the system. Irrigation fluid is delivered from a user-provided surgical saline bag, 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 fitted over the saline bag.

The foot pedal is used by the user to remotely control the function of the console. It connects to the back of the console via an electrical cable. It provides on/off functionality and is rated IPX8 for protection against liquids.

The System also includes accessories. A Travel Case is provided for shipping, handling and storage of the TX Console. A power cord is provided for connecting the Console to facility electrical power in order to operate the device. A replacement fuse set is also provided in case of the need for replacement of electrical fuses in the TX Console. The accessories are non-sterile when used and do not require processing.

The supply kit contains sterile packaged, single use, OEM surgical supply items for use in the surgical site preparation and closure. These include a syringe and needle, scalpel, an ultrasound probe cover, gauze, closure strips and dressing. The itemized contents of the kit with their manufacturer and regulatory information are provided in Table 4 below.

The Tenex Health TX System with the TXP MicroTip is an upgrade to the Tenex Health TX System (K153299), with the addition of the TXP MicroTip, an upgraded handpiece with indications for use for the treatment of hard tissue and the sharp debridement of wounds such as neuropathic ulcers.

# Indications for Use:

The Tenex Health TX System with the TXP MicroTip is indicated for use in surgical procedures where fragmentation, emulsification, and aspiration of both soft and hard (e.g.: bone) tissue are desirable, including General Surgery, Orthopedic Surgery, Laparoscopic Surgery and Plastic and Reconstructive Surgery.

The Tenex Health TX System with the TXP MicroTip is also indicated for use in the debridement of wounds, such as, but not limited to diabetic ulcers, in application, in the physician's judgement would require the use of an ultrasonic aspirator with sharp debridement.

The Tenex Health TX System with the TXP MicroTip has the same Indications for Use as the reference device, existing Tenex Health TX System (K153299), for the fragmentation, emulsification, and aspiration of soft tissue in general surgery, orthopedic surgery, laparoscopic surgery and plastic and reconstructive surgeries.

{5}------------------------------------------------

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.

	- Aspiration vacuum ●
	- Automated priming
	- Irrigation flow
	- Aspiration volume
	- Operating frequency
	- Operating temperatures ●
	- Needle stroke length ●
	- MicroTip pull strength
	- Inflation cuff pressurization
	- Collection bag performance
	- Corrosion resistance ●
	- Primary acoustic output area ●
	- . Output acoustic power
- 2) EMC and electrical safety testing verified the system met the standards:
	- IEC 60601-1:2005 + A1 2012. Medical electrical equipment = Part 1: General reguirements for ● basic safety and essential performance - Edition 3.1.

{9}------------------------------------------------

- IEC 60601-1-2:2014, Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral standard: Electromagnetic compatibility -Requirements and tests - Edition 4.0.
- 3) Biocompatibility evaluation verified the system met the standard: ISO 10993-1:2009, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process
- 4) Sterilization validation of the sterile packaged MicroTip showed the device met the standards:
	- ANSI/AAMI/ISO TIR13004:2013, "Sterilization of health care products Radiation -● Substantiation of a selected sterilization dose: Method VDmax SD.
	- ISO 11137-1:2013, Sterilization of health care products Radiation Part 1: Requirements for ● the development, validation and routine control of a sterilization process for medical devices
- 5) Packaging Validation of the sterile packaged MicroTip showed the device met the standards:
	- . ISO 11607-1:2006. Packaging for terminally sterilized medical devices - Part 1: Requirements for materials, sterile barrier systems and packaging systems
	- . ISO 11607-2:2006. Packaging for terminally sterilized medical devices – Part 2: Validation requirements for forming, sealing and assembly processes
- 6) 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.

- 7) 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.
