Device Story

FlexTip Bipolar electrodes are single-use, sterile electrosurgical instruments designed for tissue and vessel coagulation. The device consists of a handpiece, electrode front part, cable, and plug. It functions by delivering radiofrequency (RF) current to target tissue when connected to compatible RF generators (e.g., Arthrex Synergy or Sutter CURIS). Used in endoscopic, orthopedic, and neurosurgical procedures, the device is operated by surgeons. The electrode tips and shaft are stainless steel, insulated with PEBAX tubing. The device provides hemostasis through RF-induced thermal effects. Clinical benefit is achieved through effective coagulation during surgery. The device is provided sterile via ETO sterilization.

Dear Arne Briest:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
