The document does not mention AI, ML, deep learning, or any related terms in the device description, intended use, or performance studies. The features described are related to robotic control, force feedback, and eye tracking, which are not inherently AI/ML technologies.
No
The device is a surgical system intended to assist in performing laparoscopic procedures, which is a tool for treatment rather than a therapeutic device that directly treats a condition.
No
Explanation: The "Intended Use / Indications for Use" section states that the system is intended to "assist in the accurate control of laparoscopic instruments for visualization and endoscopic manipulation of tissue," and not for diagnosing conditions.
No
The device description clearly outlines multiple hardware components including a surgeon console, manipulator arms, an Intelligent Surgical Unit (ISU), and instruments. It is a robotic surgical system, not solely software.
Based on the provided information, the Senhance Surgical System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly describes a system for assisting in surgical procedures by controlling laparoscopic instruments for manipulation of tissue within the body. This is an in-vivo (within a living organism) application, not an in-vitro (outside of the body) diagnostic test.
- Device Description: The description details a robotic system with arms, instruments, and a console for performing surgery. It does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.) to diagnose a condition.
- Input Imaging Modality: The input is an "Endoscopic signal," which is a visual feed from inside the body during surgery. This is not a modality typically associated with IVD testing.
- Anatomical Site: The device is used in the "Abdomen and pelvis," which are anatomical locations within the body where surgery is performed.
- Key Metrics: The key metrics measured (Length of Stay, Complications, Blood Loss, etc.) are related to the outcome and safety of a surgical procedure, not the results of a diagnostic test.
IVD devices are designed to perform tests on samples taken from the human body to provide information for the diagnosis, monitoring, or treatment of a disease or condition. The Senhance Surgical System's function is to facilitate the performance of surgery itself.

Device Description
The Senhance Surgical System is a multi-arm, console-based robotic system that allows a surgical team to perform laparoscopic surgery in the abdomen and pelvis in a manner similar to a manual laparoscopic approach. Each robotic arm can hold either a laparoscopic surgical instrument or an endoscope to facilitate a surgeon remotely operating the instrument from the cockpit.
More specifically, the Senhance Surgical System consists of: a surgeon console (cockpit), which provides remote manipulators or handles to allow the surgeon to maneuver the surgical instruments and a video monitor to display the endoscopic signal; manipulator arms, which hold and maneuver the instruments and endoscope based on inputs from the surgeon; Intelligent Surgical Unit (ISU), which is the system communication hub, connecting the cockpit and manipulator arms; and instruments, which manipulate the tissue of interest.
In addition, force feedback provides an optional tactile sensory input to the surgeon control handles to give a sense of tissue elasticity. An eye tracking feature provides the surgeon an optional method to control the endoscope from the cockpit, rather than using the surgeon control handles. The ISU allows for three additional methods of camera control, in addition to the optional eye tracking method.

Summary of Performance Studies
Real-world evidence was collected from the TRUST registry, a prospective, multi-center patient registry sponsored by Asensus Surgical.
A retrospective clinical data review was performed using data from the TRUST registry.
From December 2017 to August 2023, 416 urology cases were performed using the Senhance system at four centers within this retrospective dataset. All patients were eligible for laparoscopic procedures with general anesthesia. Data collection is ongoing.
Clinical data collected from the TRUST registry was compared with the results from 62 peer-reviewed research publications describing the clinical outcomes for laparoscopic urological procedures using three alternative surgical techniques: laparoscopic, open, and robotically assisted surgery as part of a Systematic Literature Review (SLR).
Bench testing validated compatibility, mechanical integrity, functionality, reliability, and safe use, including verification of key device functions such as video signal, endoscope compatibility, surgical instruments, adapters, camera control, and force feedback features.

Device Description
The Senhance Surgical System is a multi-arm, console-based robotic system that allows a surgical team to perform laparoscopic surgery in the abdomen and pelvis in a manner similar to a manual laparoscopic approach. Each robotic arm can hold either a laparoscopic surgical instrument or an endoscope to facilitate a surgeon remotely operating the instrument from the cockpit.
More specifically, the Senhance Surgical System consists of: a surgeon console (cockpit), which provides remote manipulators or handles to allow the surgeon to maneuver the surgical instruments and a video monitor to display the endoscopic signal; manipulator arms, which hold and maneuver the instruments and endoscope based on inputs from the surgeon; Intelligent Surgical Unit (ISU), which is the system communication hub, connecting the cockpit and manipulator arms; and instruments, which manipulate the tissue of interest.
In addition, force feedback provides an optional tactile sensory input to the surgeon control handles to give a sense of tissue elasticity. An eye tracking feature provides the surgeon an optional method to control the endoscope from the cockpit, rather than using the surgeon control handles. The ISU allows for three additional methods of camera control, in addition to the optional eye tracking method.
The purpose of this traditional 510(k) submission is to seek clearance for modifications to the indications for use to be expanded to include laparoscopic urological surgery.
Indication For Use
The Senhance Surgical System is intended to assist in the accurate control of laparoscopic instruments for visualization and endoscopic manipulation of tissue including grasping, cutting, blunt and sharp dissection, approximation, ligation, electrocautery, suturing, mobilization, and retraction. The Senhance Surgical System is intended for use in general laparoscopic surgical procedures, laparoscopic gynecological surgery, and laparoscopic urological surgery. The system is indicated for adult and pediatric use. It is intended for use by trained physicians in an operating room environment in accordance with the instructions for use.
Use of the device is limited to patients two (2) years of age and older and a weight equal to or above 10kg, who are suitable to be subjected to a conventional endoscopic technique.
Summary of Technological Characteristics
The subject device has the same technological characteristics as the primary predicate device, the Senhance Surgical System (K223095), and similar characteristics to the reference device. Both the subject and predicate devices involve robotically assisted tele-operation as the primary technological principle. It is based on the accurate translation of user inputs to robotically assisted outputs. It involves the use of endoscopic instrumentation for manipulation of tissue and vessels in the insufflated body cavity.
The Senhance Surgical System consists of: a surgeon console (cockpit), which provides remote manipulators or handles to allow the surgeon to maneuver the surgical instruments and a video monitor display the endoscopic signal; manipulator arms, which hold and maneuver the instruments and endoscopic based on inputs from the surgeon; Intelligent Surgical Unit (ISU), which is the system

communication hub, connecting the cockpit and manipulator arms; and instruments, which manipulate the tissue of interest.
In addition, force feedback provides optional tactile sensory input to the surgeon control handles to give a sense of tissue elasticity. An eye tracking feature provides the surgeon an optional method to control the endoscope from the cockpit, rather than using the surgeon control handles. The ISU allows for three additional methods of camera control, in addition to the optional eye tracking method.
The Senhance instruments are similar in design and materials to traditional laparoscopic instrumentation.
Since there are no technological differences between the subject Senhance system and the primary predicate, no different questions of safety or effectiveness have been raised.
Substantial Equivalence:
The subject Senhance Surgical System with the expanded indications for use is substantially equivalent to the legally marketed primary predicate, Senhance Surgical System most recently cleared through K223095, and to the reference device, the Intuitive Surgical System, IS3000 (K171699).
The subject Senhance Surgical System has the same intended use, technological characteristics, and principles of operation as the primary predicate. The expanded indications for use for the subject device are supported by real-world clinical evidence and do not raise different questions of safety or effectiveness or alter the fundamental therapeutic use of the system; they also align with the intended user population cleared for the secondary predicate/reference device.
Performance Data:
There have been no changes to the device since the previous clearance (K223095), other than the modifications to expand the indications for use to include laparoscopic urological surgery indications. Extensive bench testing was conducted on the previously cleared Senhance system, and these data remain applicable to the subject device. The previously collected compatibility, mechanical integrity, functionality, reliability, and safe use, addressing verification of key device functions including video signal, endoscope compatibility, surgical instruments, and adapters, as well as validation of the system's camera control and force feedback features.
The recognized consensus standards for the predicate Senhance system (K223095) are still applicable as there have been no changes to the technological characteristics of the device.
Cybersecurity Data:
Cybersecurity information demonstrating compliance with section 524B of the FD&C Act consistent with current "FDA Guidance: Cybersecurity in Medical Devices - Quality System Considerations and Content of Premarket Submissions" was provided in this submission.
Clinical Data
6
To demonstrate that the subject device is safe and effective for the expanded indications for use, the company has collected real-world evidence on the Senhance Surgical System. A retrospective clinical data review was performed using data from the TRUST registry.
Asensus Surgical is sponsoring a clinical registry "TRUST" and encourages clinical centers in Europe to participate and enter information about the actual use of the Senhance Surgical System and its accessories into the database. This study is a prospective, multi-center patient registry. Sites additionally retrospectively enrolled previously treated patients (after obtaining informed consent) and entered retrospective data into case report forms online.
The TRUST registry aims to enable the collection of real-world evidence on the effectiveness and safety of the Senhance Surgical System and its accessories as it is routinely used within three surgical disciplines: abdominal surgery, gynecological surgery, and urological surgery.
From December 2017 to August 2023, 416 urology cases were performed using the Senhance system at four centers. All patients treated with the Senhance system within this retrospective dataset were eligible for laparoscopic procedures with general anesthesia. The data collection at the sites are still ongoing.
Systematic Literature Review (SLR)
Clinical data collected from the TRUST registry was compared with the results from 62 peer-reviewed research publications describing the clinical outcomes for laparoscopic urological procedures using three alternative surgical techniques: laparoscopic, open, and robotically assisted surgery. The table below (Table 18) summarizes the clinical data on Senhance Surgical System compared to data from the systematic literature review.

- Both the readmission and reoperation rates were calculated based on information available from adverse event listing notes. Both readmissions occurred during the 12-month follow-up phase after the patient's discharge from the hospital. Therefore, both readmission and reoperation occurred any time between the day of discharge and 12 months after discharge.
†Follow-up was performed on only 122 patients in Minsk. Hence the missing values were not included in the n% calculation.
Conclusion
The clinical analysis of the subject Senhance Surgical System demonstrated that the device is safe and effective for use in urological surgical procedures, which is comparable to that indicated for the secondary predicate (Intuitive da Vinci Si Surgical System, K171699).
The subject Senhance Surgical System has the same intended use as the predicates and its expanded indications for use do not affect the safety or effectiveness of the device. In addition, the subject device has the same technological characteristics and principles of operation as the primary predicate device. Analysis and clinical performance of the device with urological procedures indicate that no new issues of safety or effectiveness are raised for the expanded claim. Thus, the subject Senhance Surgical System is substantially equivalent to the predicate device.
