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 Description
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.

No
The description focuses on the electrosurgical generator's power output, modes, and safety features, with no mention of AI or ML capabilities.

Yes
The device is an electrosurgical generator used to supply RF signals to handpieces for electrosurgery on soft body tissues, which is a therapeutic intervention.

No

Explanation: The device is described as an electrosurgery generator used to supply RF signals to handpieces for surgical procedures (cutting and coagulation of soft body tissues). It does not mention any function for diagnosis, such as imaging, analysis of physiological signals, or identification of diseases.

No

The device description clearly states it is a "solid state monopolar generator with independent bipolar generator" and describes hardware components like power supplies and outputs, indicating it is a physical medical device, not software-only.

Based on the provided information, the Kirwan Model 28 1500 Generator is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states it's for "electrosurgical handpieces used on soft body tissues". This describes a device used on the body for surgical procedures, not a device used to test samples from the body (which is the definition of an IVD).
  • Device Description: The description details a generator that supplies RF signals for electrosurgery, again indicating a device used directly on a patient during surgery.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.), performing diagnostic tests, or providing diagnostic information based on laboratory analysis.

Therefore, the Kirwan Model 28 1500 Generator is a surgical device, not an in vitro diagnostic device.
