What is it indicated for?

The Surgical Tissue Management System is intended to be used with the Ultrasonic Generator (USG-400), the Electrosurgical Generator (ESG-400), the THUNDERBEAT Transducer (TD-TB400), the SONICBEAT Transducer (TD-5B400), the THUNDERBEAT, and / or the SONICBEAT for open, laparoscopic (including single-site surgery), and endloscopic surgery to cut (dissbct) or coagulate soft tissue or to ligate (seat and cut) vessels. The Surgical Tissue Management System…

Read the full statement (600 words)

The Surgical Tissue Management System is intended to be used with the Ultrasonic Generator (USG-400), the Electrosurgical Generator (ESG-400), the THUNDERBEAT Transducer (TD-TB400), the SONICBEAT Transducer (TD-5B400), the THUNDERBEAT, and / or the SONICBEAT for open, laparoscopic (including single-site surgery), and endloscopic surgery to cut (dissbct) or coagulate soft tissue or to ligate (seat and cut) vessels.

The Surgical Tissue Management System has three output modes, Seal & Cut (THUNOERBEAT), Seal (THUNDERBEAT) and Ultrasonic (SONICBEAT). The Seal & Cut mode provides combined HF bipolar and ultrasonic energy, the seal mode provides only HF bipolar energy and the Ultrasonic mode provides only ultrasonic energy.

This system has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.

The Ultrasonic Generator (USG-400) is intended to be used with the Electrosurgical Generator (ESG-400), the THUNDERBEAT Transducer (TD-TB400), the SONICBEAT Transducer (TD-SB400), the THUNDERBEAT, and / or the SONIOBEAT for open, laparoscopic (including single-site surgery), and endloscopic surgery to cut (dissect) or coagulate soft tissue or to ligate (seal and cut) vessels.

The ESG-400 is an electrosurgical generator intended for tissue cutting and coagulation in open, laparoscopic and endoscopic surgery in conjunction with electrosurgical accessories and ancillary equipment.

The THUNDERBEAT Transducer (TD-TB400) is intended to be used with the Ultrasonic Generator (USG-400), the Electrosurgical Generator (ESG-400), and the THUNDERBEAT for open, laparoscopic (including single-site surgery), and endoscopic surgery to cut (dissect) or coagulate soft tissue or to ligate (seal and cut) vessels.

The THUNDERBEAT hand instruments are intended to be used with the Ultrasonic Generator (USG-400), the Electrosurgical Generator (ESG-400), and the THUNDERBEAT Transducer, (TO-TB400).

Seal & Cut mode:

The THUNDERBEAT hand instruments when used in combination with the Seal & Cut mode are indicated for open, laparoscopic (including single-site surgery) general surgery and gynecological surgery (including urologic, thoracic, plastic and reconstructive, bowel resections, cholecystectomies, Nissen fundoplication, adhesiolysis, oophorectomy, hysterectomies (both vaginal assisted and abdominal) etc) and endoscopic surgery or in any procedure in which cutting, vessel ligation (sealing and cutting), coagulation, grasping, and dissection is performed. These devices have been designed to seal and cut vessels up to and including 7mm in diameter.

Seal mode:

The THUNDERBEAT hand instruments when used in combination with the Seal mode are indicated for open, laparoscopic (including single-site surgery) general surgery and gynecological surgery (including urologic, thoracic, plastic and reconstructive, bowel resections, cholecystectomies, Nissen fundoplication, adhesiolysis, oophorectomy, hysterectomies (both vaginal assisted and abdominal) etc), and endoscopic surgery or in any procedure in which vessel sealing, coagulation, grasping is performed. These devices have been designed to seal vessels up to and including 7mm in diameter.

The THUNDERBEAT hand instruments have not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.

The SONIOBEAT Transducer (TD-SB400) is intended to be used with the Ultrasonic Generator (USG-400) and the SONICBEAT for open, laparoscopic (including single-site surgery), and endloscopic surgery to cut (dissect) or coagulate soft tissue or to ligate (seal and cut) vessels.

The SONICBEAT is intended to be used with the Ultrasonic Generator (USG-400) and the SONIOBEAT Transducer (TD-SB4QO) for open, laparoscopic (including single-site surgery), and general surgery to cut (dissect), coagulate, or grasp soft tissue or to ligate (seal and cut) vessels in gynecologic, thoracic, urologic, and endoscopic surgical procedures.

These devices have been designed to seal and cut vessels up to and including 5mm in diameter.

The SONIOBEAT has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.

Indications for use as stated in the FDA summary.
