## Intended Use

The DynaBite HOT Gastroenterology Biopsy Forceps used in endoscopic procedure for removing histological tissue samples from the inner walls of the intestines and for performing associated electrocautery. The subject device is intended to be used with a colonoscope, a connecting cable and a high-frequency electrical-current generator, manufactured by others.

## Device Story

DynaBite HOT Gastroenterology Biopsy Forceps are manually operated, flexible, cable-actuated surgical instruments used during endoscopic procedures. The device features double-actuating, fenestrated cup jaws at the distal end, controlled by a two-bar linkage connected to proximal finger rings. Fabricated from electrically conductive stainless steel, the forceps transmit high-frequency waveforms from an external generator (manufactured by others) to the distal end for electrocautery. A dielectric coating and the endoscope provide electrical insulation to prevent unintended patient contact. The device is used by clinicians in a clinical setting to obtain tissue samples and perform cauterization, aiding in diagnostic and therapeutic gastrointestinal interventions.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Manually operated, flexible, cable-actuated biopsy forceps. Materials: electrically conductive stainless steel with dielectric coating. Dimensions: 2.2mm or 3.3mm diameter, 240cm length. Distal end: double-actuating, fenestrated cup jaws. Energy source: external high-frequency electrical-current generator. Connectivity: connects to colonoscope and external generator. No software or electronic components.

## Regulatory Identification

JUN 17 1997

Subject Device: DynaBite HOT Gastroenterology Biopsy Forceps

Manufacturer: Portlyn Corporation

Predicate Device 1: MicroVasive Hot Biopsy Forceps

Distributor: Boston Scientific Corporation

Predicate Device 2: Hot Biopsy Forceps

Distributor: Olympus

Predicate Device 3: DynaBite GI Biopsy Forceps (non-electric)

Manufacturer: Portlyn Corporation

Subject Device Description: The DynaBite HOT Gastroenterology Biopsy Forceps are manually operated, hand held, flexible, cable actuated, coated, monopolar, trans-rectal surgical instruments have diameters of either 2.2, or 3.3 millimeter and working lengths of 240 centimeter. Each forceps has a pair of double actuating, fenestrated cup jaws at the distal end. Both devices are used in endoscopic procedure for removing histological tissue samples from the inner walls of the intestines and for performing associated electrocautery. The subject device is intended to be

used with a colonoscope, a connecting cable and a high-frequency electrical-current generator, manufactured by others. The distal jaws of the forceps are open and closed with a two bar linkage actuated by lateral motion of the proximal finger rings. Since the forceps are fabricated from electrically conductive stainless steels, the forceps may be used to transmit a high frequency waveform to the distal end of the forceps for electrocautery. A dielectric forceps coating and the endoscope electrically insulate the length of the forceps from unintended patient contact. The technological characteristics of the DynaBite HOT Gastroenterology Biopsy Forceps are time tested and used by other legally marketed HOT biopsy forceps.

Intended Use: The DynaBite HOT Gastroenterology Biopsy Forceps used in endoscopic procedure for removing histological tissue samples from the inner walls of the intestines and for performing associated electrocautery. The subject device is intended to be used with a colonoscope, a connecting cable and a high-frequency electrical-current generator, manufactured by others. The

intended use and technological characteristics of the subject device is the same as the first two predicate devices. The third predicate device defers only in the electrocautery feature.

I, to the best of my knowledge, believe the that all data and information submitted in this 510(k) premarket notification is truthful and accurate and that no material facts have been omitted.

21 CFR §876.4300/Product code: 78 KGE

Dear Mr. Lyna:

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 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 Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP 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.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4616.
