Intended Use
The Somnus™ Electrode Bending Tool is an accessory to the Somnus Bendable Tissue Coagulating Electrode. The Bending Tool is intended for use by qualified medical personnel trained in the use of Somnus Tissue Coagulating Electrodes. The Somnus Model 1000 - Needle Sleeve Bending Tool is intended to change the angle of deployment of the needle for the Model 1000 - Single Needle Coagulating Electrodes by creating a radial bend in the needle sleeve. The Somnus Bendable Tissue Coagulating Electrodes are intended for use in the coagulation of tissue.
Device Story
The Somnus Electrode Bending Tool is a mechanical accessory used to modify the geometry of the Somnus Bendable Tissue Coagulating Electrode. The tool creates a radial bend in the electrode's needle sleeve, allowing the needle to be deployed at specific angles ranging from 0 to 45 degrees. It is operated by qualified medical personnel in a clinical setting. By enabling adjustable needle deployment angles, the tool facilitates precise positioning of the coagulating electrode for thermal tissue ablation. The device is purely mechanical and does not involve electronic processing or software.
Clinical Evidence
Bench testing only.
Technological Characteristics
Mechanical hand-held tool; manual operation; designed to create a radial bend in the needle sleeve of the Somnus Model 1000 Coagulating Electrode; enables needle deployment angles from 0 to 45 degrees.
Indications for Use
Indicated for use by qualified medical personnel to adjust the needle deployment angle (0 to 45 degrees) of the Somnus Model 1000 Single Needle Coagulating Electrode by creating a radial bend in the needle sleeve. No known contraindications.
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.

Dear Dr. Conner:
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.
