No
The document describes a standard electrosurgical generator and associated accessories. There is no mention of AI, ML, or any features that would suggest the use of such technologies for image processing, data analysis, or decision-making within the device's operation. The technology described is focused on generating and controlling high-frequency electrical energy for tissue cutting and coagulation.
Yes
The device is indicated for surgical procedures involving the cutting, coagulation, ligation, and division of tissue and vessels to achieve hemostasis, which are therapeutic actions to treat or manage a medical condition.
No
Explanation: The device is an electrosurgical generator designed for cutting, coagulating, ligating, and dividing tissue, and sealing vessels. Its intended use is for surgical procedures to achieve hemostasis and remove/coagulate tissue. It does not perform any diagnostic functions like analyzing, detecting, or measuring biological signals or conditions to identify a disease or medical condition.
No
The device description clearly outlines hardware components such as an electrosurgical generator, handpieces, cables, and a wireless footswitch, all of which are physical devices used for surgical procedures. While it mentions a touchscreen GUI, this is part of the hardware system, not a standalone software device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended use clearly states the device is for "surgical procedures for the cutting and/or coagulation of tissue," "removal or coagulation of tissue in 0.9% NaCl solution," and "ligation and division of tissue bundles, lymphatics, and vessels." These are all procedures performed on the patient's body, not on samples taken from the body for diagnostic purposes.
- Device Description: The description reinforces its use in surgical procedures for "electrosurgical destruction of the tissue" and "sealing vessels."
- No mention of in vitro testing: There is no mention of analyzing samples (blood, tissue, etc.) outside of the body for diagnostic information.
- Focus on surgical intervention: The entire description and intended use revolve around performing surgical actions on the patient.
IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device's function is entirely focused on surgical treatment and intervention.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Benchtop and ex-vivo comparison testing, in-vivo simulated use testing, and chronic animal studies support that the ConMed Unify MEP is substantially equivalent to the ConMed HelixAR and Valleylab FT10 Electrosurgical Generators in intended use, technology, and system performance.
Mechanical and electrical verification activities and software validation demonstrate the Unify Multifunction Energy Platform complies with the applicable sections of AAMI/ANSI ES60601-1, IEC 60601-2-2, IEC 60601-1-2, and IEC 62304. Risk management activities in accordance with ISO 14971 demonstrate the risks associated with the use of the Unify Multifunction Energy Platform are mitigated to an acceptable level. Analyses of these activities conclude the benefits associated with the use of the Unify MEP outweigh the residual risks.
A chronic animal study was conducted according to FDA quidance, "Premarket Notification (510(k)) Submissions for Bipolar Electrosurgical Vessel Sealers for General Surgery" Guidance for Industry and Food and Drug Administration Staff, issued on August 15, 2016; and "Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery" Guidance for Industry and Food and Drug Administration Staff, issued on March 9, 2020. The study evaluated the performance of the ConMed Unify ESU with the CleanSeal 5mm Maryland vessel sealing handpiece (Test system) in comparison to the Valleylab FT10 ESU with the LigaSure Maryland with Nanocoating, 37 cm (Predicate system). After 21 days in the porcine model, the treatment of vascular structures (i.e., arteries, veins, and arterio-venous [A/V] bundles) with the ConMed Unify ESU with the CleanSeal 5mm Maryland vessel sealing hand piece was determined to result in the effective sealing of treated vessels.

H. Performance Testing
The Unify MEP has been tested according to the applicable requirements listed in FDA guidance "Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery" and "Premarket Notification (510(k)) Submissions for Bipolar Electrosurgical Vessel Sealers for General Surgery". Benchtop and ex-vivo comparison testing, in-vivo simulated use testing, and chronic animal studies support that the ConMed Unify MEP is substantially equivalent to the ConMed HelixAR and Valleylab FT10 Electrosurgical Generators in intended use, technology, and system performance.
Mechanical and electrical verification activities and software validation demonstrate the Unify Multifunction Energy Platform complies with the applicable sections of AAMI/ANSI ES60601-1, IEC 60601-2-2, IEC 60601-1-2, and IEC 62304. Risk management activities in accordance with ISO 14971 demonstrate the risks associated with the use of the Unify Multifunction Energy Platform are mitigated to an acceptable level. Analyses of these activities conclude the benefits associated with the use of the Unify MEP outweigh the residual risks.
l. Biocompatibility Test
The CleanSeal 5mm Vessel Sealer (CleanSeal 5mm VS) used with Unify ESU is in compliance with 2020 FDA Guidance of Use of International Standard ISO 10993-1, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process". The biological test results support that the CleanSeal 5mm VS met the acceptance criteria for the following biocompatibility test endpoints.

J. Chronic Animal Study
A chronic animal study was conducted according to FDA quidance, "Premarket Notification (510(k)) Submissions for Bipolar Electrosurgical Vessel Sealers for General Surgery" Guidance for Industry and Food and Drug Administration Staff, issued on August 15, 2016; and "Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery" Guidance for Industry and Food and Drug Administration Staff, issued on March 9, 2020. The study evaluated the performance of the ConMed Unify ESU with the CleanSeal 5mm Maryland vessel sealing handpiece (Test system) in comparison to the Valleylab FT10 ESU with the LigaSure Maryland with Nanocoating, 37 cm (Predicate system). After 21 days in the porcine model, the treatment of vascular structures (i.e., arteries, veins, and arterio-venous [A/V] bundles) with the ConMed Unify ESU with the CleanSeal 5mm Maryland vessel sealing hand piece was determined to result in the effective sealing of treated vessels.
K. Reprocess
The Unify Reusable Bipolar Resection Cable (BPR Cable) was tested to be compatible with ConMed Unify ESU and Karl Storz or Richard Wolf resectoscopes. The BPR Cable may be cleaned and sterilized up to 50 use cycles. The BPR Cable is designed and manufactured as a reusable device in accordance with FDA Guidance "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling" and FDA recognized consensus standard ISO 17664:2017 Processing of health care products - Information to be provided by the medical device manufacturer for the processing of medical devices.
L. Substantial Equivalence
The differences between the predicate devices and the proposed device do not raise any new risks of safety or efficacy. Supporting information per this premarket submission, including but not limited to the bench tests, tissue validation, chronical animal study and the benefit-risk analysis, confirms that the Unify MEP is safe and effective for its intended use and is substantially equivalent in design, intended use, principals of operation, and technical characteristics to the ConMed HelixAR and Valleylab FT10 Electrosurgical Generators. The CleanSeal Vessel Sealer, in conjunction with Unify MEP, is also substantially equivalent to the reference device LigaSure Maryland Jaw Sealer/Divider (K170869) used with the predicate ValleyLab FT10.
