Device features 0-50 digital power display (+/- 5 watts at 100 ohms) and bar graph output current monitor. Handswitch operates on isolated 7 Vdc power supply. Designed for clinical use by medical professionals. Monitors provide audio/visual feedback during activation. Safety compliance includes IEC 601-1-2 and ANSI HF-18 standards for isolated body-floating bipolar coagulators. Device intended to manage varying tissue impedances during surgical procedures. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Solid-state bipolar RF generator. Features digital power display (0-50 scale) and bar graph current monitor. Isolated 7 Vdc power supply for handswitch. Complies with IEC 601-1-2 and ANSI HF-18 safety standards for isolated (body floating) bipolar coagulators. ## Regulatory Identification An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Food and Drug Administration 0K Document Mail Center HFZ-401 Center for Medical Devices 1390 Piccard Drive Rockville, Maryland 20850 MAY 2 2 1997 K 971341 To: Document Control Clerk This summary of 510K safety and effectiveness for the Kirwan 28 1000 Coagulator is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807,92. A 0-50 digital display power setting indicator provides the operator a parallax free reading of the power setting (+/- Swatts, full scale (@ 100 ohms). A bar graph display output current monitor provides the operator a relative measure of the output current amplitude and to denote the presence of output energy during activation. The handswitch is powered by an independent low voltage (7 Vdc) isolated power supply. Audio and Visual monitors are in accord with IEC 601-1-2 and ANSI HF-18 guidelines. IF and Low Frequency leakages are well within IEC 601-1-2 and ANSI HF-18 safety guide lines for isolated (body floating) ipolar coagulators. This device is identical to an existing approved device.
