The ABCFlex™ Probe is intended for use with the System 7500® -B for non-contact superficial ablation and hemostasis through a flexible endoscope to the operative site. ## Device Story System 7500-B is an electrosurgical generator with Argon Beam Coagulation (ABC) capability. ABCFlex Probe connects to generator to deliver argon gas and high-frequency (HF) electrosurgical current to a tungsten electrode tip. Ceramic tip insulates thermal plastic tubing from heat; prevents electrode contact with patient tissue. Surgeon controls gas flow and current via switching element on generator. Used in endoscopic procedures (gastroenterology, bronchoscopy) for superficial ablation and hemostasis. Operates via contact (desiccation) or non-contact (fulguration) modes. Provides therapeutic tissue destruction; benefits include controlled coagulation and hemostasis in endoscopic settings. ## Clinical Evidence Bench testing only. Compliance with recognized consensus standards for electrosurgical devices (IEC 60601-1, 60601-2-2), sterilization (ISO 11135), and biocompatibility (ISO 10993) was demonstrated. ## Technological Characteristics Electrosurgical generator with argon beam coagulation. Materials: tungsten electrode, ceramic tip, thermal plastic tubing. Energy: HF electrosurgical current. Standards: ANSI/AAMI HF-18, IEC 60601-1, 60601-1-1, 60601-1-2, 60601-1-4, 60601-2-2, ISO 11135, ISO 10993. Sterilization: Ethylene Oxide. ## Regulatory 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. ## Predicate Devices - System 7500® Electrosurgical Unit ([K981220](/device/K981220.md)) - ABC® Probe for Flexible Endoscopes ([K990586](/device/K990586.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

ABC ® Probe for Flexible Endoscopes, K990586, cleared 17-May-1999 | K 050161 Summary of Safety and Effectiveness Device Description: The System 7500 -B is an electrosurgical generator with Argon Beam Coagulation (ABC) capability. The basic modes of operation are conventional electrosurgical cutting, coagulation plus argon beam coagulation. When cutting, the edge of the electrode is drawn across the tissue while electrosurgical energy is being applied. When coagulating, the accessory electrode or argon beam may be held in contact with the tissue for desiccation or separated from the tissue by distance for fulguration to achieve the desired result. The ABCFlex™ Probe has applications in endoscopic surgical procedures such as upper and lower gastroenterology and bronchoscopy to provide a means of coagulation using electrosurgical current and argon gas. The device consists of a connector for delivering argon gas to the operative site as well as an internal cable to carry high frequency (HF) electrosurgical current to a tungsten electrode tip at the end of the tubing. A ceramic tip insulates the thermal plastic tubing from the heat generated during coagulation. The electrode is positioned in the ceramic tip such that it cannot contact the patient's tissue during the coagulation procedure. Current and gas flow is controlled by the surgeon activating and deactivating a switching element part of the System 7500 -B ESU.
