Intended Use

Davis Bayonet Electrodes are intended for use in open surgical procedures where monopolar electrosurgical cutting and coagulation are normally used. The Electrodes are intended for use in conventional electrosurgical pencils and chucks as alternatives to other electrosurgical electrodes.

Device Story

Sterile, single-use electrosurgical electrodes; extended shaft with offset bayonet shape; loop, ball, and needle tip configurations. Used in open surgery within cavities or recessed areas to improve surgeon visibility. Compatible with conventional electrosurgical pencils and chucks. Operates by conducting high-frequency electrical current from electrosurgical generators to patient tissue for cutting and coagulation. Used by surgeons in clinical/OR settings. Benefits include enhanced visualization in deep surgical sites compared to straight electrodes.

Clinical Evidence

Bench testing only. Functional testing performed on chicken breast tissue; insulation tested at 60Hz and radio frequencies; assembly and removal force testing; environmental, vibration, and drop testing for packaging.

Technological Characteristics

Monopolar electrosurgical electrodes; loop, ball, or needle tips; extended bayonet-shaped shaft. Complies with AAMI HF18 (1993) and IEC 601-2-2 (1991-09). Sterile, single-use. Compatible with standard electrosurgical pencils.

Indications for Use

Indicated for patients undergoing open surgical procedures requiring monopolar electrosurgical cutting and coagulation.

Regulatory Classification

Identification

# SUMMARY OF SAFETY AND EFFECTIVENESS FOR DAVIS BAYONET™ ELECTRODES

K964602

## Intended Use

Davis Bayonet Electrodes are intended for use in open surgical procedures where monopolar electrosurgical cutting and coagulation are normally used. The Electrodes are intended for use in conventional electrosurgical pencils and chucks as alternatives to other electrosurgical electrodes.

## Product Description

Davis Bayonet Electrodes are sterile, single use, electrosurgical electrodes with an extended length shaft and an offset bayonet shape to permit the surgeon to see the end of the electrode more easily when performing surgery in cavities or recessed areas. The Electrodes are available with loop, ball, and needle tip configurations.

## Safety and Performance

### 1. Biocompatibility Testing

The biological safety of the Davis Bayonet Electrodes has been assured through the selection of materials which demonstrate appropriate levels of biocompatibility. The components of the Electrodes have incidental short term contact with patient tissues at the surgical site.

### 2. Performance Testing

The Davis Bayonet Electrodes have been designed to conform with the applicable sections of AAMI HF18, 1993, Electrosurgical Devices, and IEC 601-2-2, 1991-09, Medical Electrical Equipment, Part 2: Particular Requirements for the Safety of High Frequency Surgical Equipment. Performance testing was conducted on representative product.

## Electrical Testing

Electrode insulation was tested at both low frequency (60Hz) and radio frequency typical of electrosurgical generators. The insulation passed all test requirements.

## Functional Testing

Functional tests were performed on chicken breast in the laboratory. All electrodes performed properly and no electrode damage occurred at recommended power levels.

## Assembly Testing

Electrodes assembled properly into Valleylab electrosurgical pencils, and exhibited an appropriate removal force. The force required to separate the electrode tip from the electrode shaft also met performance requirements.

## Package and Shipping Testing

Packaged product was subjected to environmental conditioning and rigorous vibration and drop testing. No significant damage occurred.

## Substantial Equivalence

Davis Bayonet Electrodes are substantially equivalent in function and intended use to the following legally marketed devices.

- Valleylab E1000 series Electrodes
- Valleylab E1550 series Electrodes
