The ForceTriad is a full-featured electrosurgical generator intended for open and laparoscopic surgical procedures where the surgeon requires electrosurgical cutting (resecting, dividing, or separating), coagulation (hemostasis, coagulating, or desiccating), or vessel sealing or fusing.). The generator is intended for use in general, laparoscopic, and gynecologic surgical procedures where ligation of vessels, pulmonary vasculature, or lymph vessels, is desired. The system creates a vessel ligation (seal) by the application of bipolar electrosurgical RF energy (coagulation) to vessels interposed between the jaws of the device. The generator can also be used with standard bipolar devices where bipolar cutting or coagulation is desired or with compatible resectoscopes for endoscopically controlled removal (resection) or coagulation of tissue using 0.9% NaCl solution (saline) as the irrigation medium. The indications for use include general (including urologic, thoracic, plastic, and reconstructive), laparoscopic, and gynecological procedures where electrosurgical cutting and coagulation of tissue, and sealing (fusion) of vessels, including pulmonary vessels, and tissue bundles is performed, including such procedures as bowel resections, hysterectomies (both vaginal and abdominal), laparoscopic cholesystectomies, laparoscopically assisted vaginal hysterectomies, gall bladder procedures, Nissen fundoplication, adhesiolysis, oophorectorny, etc. The devices can be used on vessels (arteries, veins. pulmonary arteries, pulmonary veins, lymph) up to 7mm and bundles as large as will fit in the jaws of the instruments. The LigaSure tissue fusion function has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this function for these procedures.

The ForceTriad™ Electrosurgical Generator is a full-featured electrosurgical generator with monopolar, bipolar, and LigaSure™ vessel sealing output modes. TThe generator is an electrically isolated, microcontroller-based device, incorporating closed-loop control for all output modes implemented in the microcontroller firmware. The generator incorporates Instant Response™ technology to constantly measure the electrical impedance of the tissue and instantaneously adjust the generator output to maintain the desired power. The generator is used with a selection of electrosurgical instruments designed for use with the ForceTriad and the LigaSure Vessel Sealing generator. All of the LigaSure instruments are capable of sealing vessels up to, and including, 7mm, and tissue bundles as large as can fit in the jaws of each instrument. When a LigaSure instrument is applied to a vessel or tissue bundle and RF energy is applied, the collagen and elastin in the tissues are reformed by heat and pressure to fuse vessel walls, thereby forming a permanent seal. The microprocessor in the generator monitors the tissue properties, stops the application of energy, and allows a brief period of cooling before indicating that the seal cycle is complete. No changes are being made to the design, operation, or intended use of any of the current system except the software modifications to create the Bipolar Resection modes and to allow the ForceTriad to output system data to a computer. The subject of this 510(k) notification is in regards to the addition of specific definitions for "cut" and "coagulating" and the addition to the indications statement of a bipolar resection function for use with resectoscopes "for endoscopically controlled removal of tissue using 0.9% NaCl solution (saline) as the irrigation medium" and the hardware and software associated with the activation of this feature.

The Valleylab Microwave Ablation Generator is intended for use in percutaneous, laparoscopic, and intraoperative coagulation (ablation) of soft tissue, including partial or complete ablation of non-resectable liver tumors.

The Valleylab Microwave Ablation Generator is designed to provide microwave power for the ablation of soft tissue in medical procedures. It was cleared for commercial distribution (K011676) by demonstrating substantial equivalence to existing Radiofrequency and Microwave Ablation systems. The Microwave Ablation Generator is designed to be used with proprietary microwave antennas (cleared in K011676 and K032702) which are placed directly into the tissue to be ablated. The Valleylab Microwave Ablation Generator is a nonsterile electrical device that is not intended to contact the patient. The Microwave Ablation Generator is used with a pump to circulate cooling fluid (sterile saline) to the antennas, and an optional integrated cart. The device's power output and duration (time) are controlled by the user via manual controls on the front panel of the generator. The display on the front of the device shows power (watts), duration of power delivery (minutes and seconds), and elapsed time. The antenna is connected to the generator and radiates power to the tissue under treatment. The antennas are provided sterile, for single use only. The shaft of each antenna is made of insulated stainless steel. Three antennas of different lengths are available for use in percutaneous procedures, and a single length antenna fing surgical procedures. The active portion of the antenna is 3.7cm in length for all models. The percutaneous antennas are cooled by circulating sterile saline through the antenna. The surgical antennas are not internally cooled. The system pump circulates fluid from a reservoir to the antenna through sterile tubing. Sterile fluid is confined within the antenna and tubing, and does not contact the patient.
