Intended Use

The Kirwan Model 28 1500 Generator is a general purpose solid state monopolar generator with independent bipolar generator to supply the RF signal to electrosurgical handpieces used on soft body tissues where a wide range of tissue types, patient conditions, and load impedances are encountered.

Device Story

Kirwan Model 28 1500 is an isolated output electrosurgery generator; features independent monopolar and bipolar circuits. Monopolar output: 0-150 watts (cut, blend 1, blend 2 modes) and 0-75 watts (coagulation). Bipolar output: 0-50 watts. Powered by independent 7 Vdc low voltage isolated power supplies. Used in clinical settings by surgeons to perform tissue cutting and coagulation. Device provides RF energy to electrosurgical handpieces; outputs are RF isolated. Audio and visual monitors provide feedback to the operator. Benefits include precise tissue management during surgical procedures.

Clinical Evidence

Bench testing only. Compliance with IEC 601-1-2 and ANSI HF-18 safety guidelines for RF and low-frequency leakage.

Technological Characteristics

Solid-state electrosurgery generator; isolated output design. Monopolar (0-150W cut/blend, 0-75W coag) and bipolar (0-50W) outputs. Independent 7 Vdc power supplies. Audio/visual monitoring. Complies with IEC 601-1-2 and ANSI HF-18 standards.

Indications for Use

Indicated for use as a general purpose electrosurgical generator to supply RF signals to handpieces for cutting and coagulation of soft body tissues across various patient conditions and tissue types.

Regulatory Classification

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.

To: Document Control Clerk

This summary of 510K safety and effectiveness for the Kirwan Model 28 1500 electrosurgery generator is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.

An isolated output monopolar electrosurgery generator with independent bipolar electrosurgery generator. The monopolar generator has continuously adjustable 0-150 watts in three cut modes of cut, blend 1, blend 2 and two coagulation modes 0-75 watts. The bipolar generator is continuously adjustable 0-50. Outputs of both generators are independently controlled and RF isolated from each other.

Each generator handswitch system is powered by independent low voltage (7 Vdc) isolated power supplies.

Audio and Visual monitors are in accord with IEC 601-1-2 and ANSI HF-18 guidelines.

RF and Low Frequency leakages are well within IEC 601-1-2 and ANSI HF-18 safety guide lines for isolated (body floating) monopolar electrosurgerygenerators and bipolar coagulators.

Sincerely,

Kambhavi

Dear Mr. Prario:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
