No
The description focuses on the mechanical and energy delivery aspects of the ultrasonic system and its integration with a robotic surgical system. There is no mention of AI or ML in the device description, intended use, or performance studies.
No.
The device is used for surgical incisions, which is an interventional procedure, not a therapeutic one.
No
The device is described as an "energized instrument system" used for "soft tissue surgical incisions" and for "manipulating laparoscopically based instruments in surgery." Its function is therapeutic (cutting and controlling bleeding), not diagnostic.
No
The device description clearly lists multiple hardware components (Dissector, Transducer, Senhance Adapter, Ultrasonic Generator, Footswitch) and the performance studies include extensive testing of these hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "soft tissue surgical incisions when bleeding control and minimal thermal injury are important." This describes a surgical tool used directly on a patient's tissue during a procedure.
- Device Description: The description details a system that delivers ultrasonic energy to tissue for incisions. This is a surgical instrument, not a device used to test samples (like blood, urine, or tissue) in vitro (outside the body) for diagnostic purposes.
- Anatomical Site: The anatomical site is "Soft tissue," which is consistent with a surgical instrument used directly on the body.
- Intended User / Care Setting: The intended users are surgeons and surgical assistants in an operating room environment, which is where surgical procedures take place.
- Performance Studies: The performance studies focus on the device's mechanical, electrical, and tissue interaction properties during surgery, not on the accuracy of diagnostic measurements from biological samples.
- Predicate and Reference Devices: The predicate and reference devices are also ultrasonic surgical systems, further confirming its classification as a surgical instrument.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The following performance testing of the Senhance Ultrasonic System was conducted to support the substantial equivalence of the device:
Biocompatibility testing: The biocompatibility evaluation for the Senhance Ultrasonic System relied on testing for the manual reference device and newly performed testing. All patient contacting devices were assessed in accordance with the FDA Guidance for Industry and FDA Staff "Use of International Standard ISO 10993-1, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process" issued on June 16, 2016, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The dissector and transducer are considered tissue contacting for a limited duration of less than 24 hours for contact with tissue or bone.
Cleaning, Disinfection (Reprocessing) and Sterilization: The reusable transducer and adapter have cleaning instructions that have been validated based on the guidelines outlined in AAMI TIR12:2010 and ANSI/AAMI TIR30:2011. A steam sterilization study was conducted in accordance with the FDA's Guidance for Industry and FDA Staff "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling" issued on: March 17, 2015 and the FDA recognized consensus standards ANSI/AAMI/ISO 17665-1:2006/(R) 2013 and ANSI/AAMI/ISO 14937:2009/(R)2013. Both items were validated to a Sterlity Assurance Level of 10° using the Half Cycle Testing validation method.
The disposable dissector is provided sterile to the end user via ethylene oxide sterilant in a fixed rigid chamber (FDA Established Category A). Sterility validation established the Sterlity Assurance Level of 106 per EN ISO 11135-1:2014 with EO and ECH residuals meeting the acceptance criteria per EN ISO 10993-7:2008.
Bench Testing: Bench testing included system integrations of the Ultrasonic System with the Surgical System as well as tests to determine any effects of the instrument to the ultrasonic energy delivered. The following tests confirmed compatibility of the systems and that the ultrasonic energy delivery to tissue is comparable to that provided by the reference system:
- Cantilever bend stiffness characterization
- Force Feedback Response Linearity, Sensitivity and Stability
- Fulcrum Accuracy
- Jaw output force verification
- Mechanical reliability of the dissector
- Thermal spread characterization of end effector and adjacent tissue
- Tissue effects vessel sealing burst pressure comparison
- Tissue effects lesion size comparison on soft tissues
As both the reference and predicate have demonstrated safe and effective use for soft tissue dissections, the subject device has demonstrated equivalence with the predicate.
Electrical Safety and Compatibility: The Senhance Ultrasonic System components as well as the Senhance Surgical System comply with current versions of IEC 60601-1 (Basic safety and essential performance), IEC 60601-1-2 (Electromagnetic disturbances), and IEC 60601-2-2 (High frequency surgical equipment). Previous testing and analysis demonstrate electrical safety and electromagnetic compatibility of the Senhance Ultrasonic system in the operating room environment. Although the system does not contain an endoscopic vision system, the effects of the energy delivered on the vision system in use concurrently with the system was evaluated using IEC 60601-2-18 (Endoscopic Equipment). The testing verified that the devices when used concurrently do not cause interference in the vision system signal.
Software Verification and Validation Testing: Software verification were conducted on both the Senhance Surgical System software modification which supported the extension to incorporate the Senhance Ultrasonic System components and also the Senhance Ultrasonic Generator. Documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". The software was considered as a "major" level of concern.
Pre-Clinical Design Validation: Design Validation of the Senhance Ultrasonic system was conducted to ensure that the system conforms to defined user needs and intended uses in a simulated use environment. A single-center, un-blinded, observational, simulated use design validation evaluation of the Senhance System was conducted with users who represented the intended primary user population.
Four (4) teams of trained subjects (one surgeon and one surgical assistant per team) performed surgical tasks and procedures on a live porcine model, which most closely represents the human anatomy for the given procedures were non-survival and did not include any animal endpoints. Users were divided into two surgical specialties: gynecological and general surgery. Two gynecological teams each performed a bilateral salpingo-oophorectomy, and a hysterectomy. Two general surqical teams each performed a cholecystectomy, dissection of short gastric vessels and a liver wedge resection. All pre-determined acceptance criteria were met.

> Intended Use/ Indications for Use:
The Senhance Ultrasonic System and accessories are indicated for soft tissue surgical incisions when bleeding control and minimal thermal injury are important. The Senhance Ultrasonic Surgical System and accessories are indicated for use with the Senhance Surgical System.
Comparison with Predicate Device Intended Use/ Indications for Use:
The Senhance Ultrasonic System has the same intended use as the predicate Intuitive Surgical 5mm Harmonic ACE Curved Shears as cleared in K112584. The da Vinci Harmonic ACE Curved Shears are intended for soft tissue incisions when bleeding control and minimal thermal injury are desired. It is designed to be used in conjunction with the da Vinci Surgical Systems (Models IS1200, IS2000 and IS3000) and a compatible Ethicon Endo-Surgery Generator and Handpiece. Thus the intended use (soft tissue incisions when bleeding control and minimal thermal injury are important/desired) is the
2
same and both systems reference the larger robotically assisted surgical device system with which they are intended to be used.
VI. Summary of Technological Characteristics:
The Senhance™ Ultrasonic System has the same basic technological characteristics as the predicate Intuitive Surgical 5mm Harmonic ACE curved Shears cleared under K112584. Both systems robotically manipulate a variant of a standard manual laparoscopic instrument that delivers ultrasonic energy to the tissue of interest. The Intuitive Surgical predicate adapted the Harmonic ACE manual laparoscopic instrument (K042777) and the Senhance Ultrasonic System is an adaptation of the BOWA Lotus manual laparoscopic system cleared under K151101.
The Senhance Ultrasonic system includes some technological characteristics that differ from the predicate device. The end effector design is different (12mm shear versus 14mm shear for the predicate) and there are different materials of construction. The wavelength of the ultrasonic energy differs between the systems as well as its mode (torsional for Senhance versus linear for Harmonic ACE). See the table below for a description of the technological differences among the subject, predicate and reference device systems.

Performance testing demonstrated that the technological differences between the Senhance System and the predicate device did not raise any different questions of safety or effectiveness. The end effectors are both made of biocompatible materials that are either effectively provided sterile to the end user or can be effectively cleaned and sterilized by the end user. Both systems effectively create soft tissue incisions with effective hemostasis and minimal thermal damage to adjacent tissues.
VII. Performance Data
The following performance testing of the Senhance Ultrasonic System was conducted to support the substantial equivalence of the device.
Biocompatibility testing: The biocompatibility evaluation for the Senhance Ultrasonic System relied on testing for the manual reference device and newly performed testing. All patient contacting devices were assessed in accordance with the FDA Guidance for Industry and FDA Staff "Use of International Standard ISO 10993-1, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process" issued on June 16, 2016, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The dissector and transducer are considered tissue contacting for a limited duration of less than 24 hours for contact with tissue or bone.
Cleaning, Disinfection (Reprocessing) and Sterilization: The reusable transducer and adapter have cleaning instructions that have been validated based on the guidelines outlined in AAMI TIR12:2010 and ANSI/AAMI TIR30:2011. A steam sterilization study was conducted in accordance with the FDA's Guidance for Industry and FDA Staff "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling" issued on: March 17, 2015 and the FDA recognized consensus standards ANSI/AAMI/ISO 17665-1:2006/(R) 2013 and ANSI/AAMI/ISO 14937:2009/(R)2013. Both items were validated to a Sterlity Assurance Level of 10° using the Half Cycle Testing validation method.
The disposable dissector is provided sterile to the end user via ethylene oxide sterilant in a fixed rigid chamber (FDA Established Category A). Sterility validation established the Sterility Assurance Level of 106 per EN ISO 11135-1:2014 with EO and ECH residuals meeting the acceptance criteria per EN ISO 10993-7:2008.
Bench Testing: Bench testing included system integrations of the Ultrasonic System with the Surgical System as well as tests to determine any effects of the instrument to the ultrasonic energy delivered. The following tests confirmed compatibility of the systems and that the ultrasonic energy delivery to tissue is comparable to that provided by the reference system.
- Cantilever bend stiffness characterization
- Force Feedback Response Linearity, Sensitivity and Stability ●
- Fulcrum Accuracy
- . Jaw output force verification
- Mechanical reliability of the dissector ●
- . Thermal spread characterization of end effector and adjacent tissue
- Tissue effects vessel sealing burst pressure comparison ●
- Tissue effects lesion size comparison on soft tissues ●
As both the reference and predicate have demonstrated safe and effective use for soft tissue dissections, the subject device has demonstrated equivalence with the predicate.

Electrical Safety and Compatibility: The Senhance Ultrasonic System components as well as the Senhance Surgical System comply with current versions of IEC 60601-1 (Basic safety and essential performance), IEC 60601-1-2 (Electromagnetic disturbances), and IEC 60601-2-2 (High frequency surgical equipment). Previous testing and analysis demonstrate electrical safety and electromagnetic compatibility of the Senhance Ultrasonic system in the operating room environment. Although the system does not contain an endoscopic vision system, the effects of the energy delivered on the vision system in use concurrently with the system was evaluated using IEC 60601-2-18 (Endoscopic Equipment). The testing verified that the devices when used concurrently do not cause interference in the vision system signal.
Software Verification and Validation Testing: Software verification were conducted on both the Senhance Surgical System software modification which supported the extension to incorporate the Senhance Ultrasonic System components and also the Senhance Ultrasonic Generator. Documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". The software was considered as a "major" level of concern
Pre-Clinical Design Validation: Design Validation of the Senhance Ultrasonic system was conducted to ensure that the system conforms to defined user needs and intended uses in a simulated use environment. A single-center, un-blinded, observational, simulated use design validation evaluation of the Senhance System was conducted with users who represented the intended primary user population.
Four (4) teams of trained subjects (one surgeon and one surgical assistant per team) performed surgical tasks and procedures on a live porcine model, which most closely represents the human anatomy for the given procedures were non-survival and did not include any animal endpoints. Users were divided into two surgical specialties: gynecological and general surgery. Two gynecological teams each performed a bilateral salpingo-oophorectomy, and a hysterectomy. Two general surqical teams each performed a cholecystectomy, dissection of short gastric vessels and a liver wedge resection. All pre-determined acceptance criteria were met.
Conclusions VIII.
The Senhance™ Ultrasonic System has the same intended use as the predicate device. There are technological differences between the subject device and the predicate device, but these raise no different questions of safety or effectiveness. Further, the device is an adaptation of the BOWA Lotus manual laparoscopic system cleared under K151101. The performance testing supported the safety and functionality of the device and demonstrate the device is substantially equivalent to the predicate device.
