The Acessa Guidance System is indicated for enhancing the ultrasonic image of the Acessa Handpiece and for predicting its future path on a computer monitor screen which also shows the image of a B-scan (or similar display) of a medical ultrasound imaging system. The device is intended as an optional accessory for use during the Acessa System procedure.

The Acessa Guidance System consists of the following components: Guidance Controller (Model Number 5100), Guidance Ultrasound Transducer Sleeve (Model Number 5500), Guidance Field Generator (Model Number 5200), Guidance Handpiece Cable (Model Number 5400), and Power Cord (Model Number 4110). The Acessa Guidance System uses electromagnetic tracking technology to track the positions of the Guidance Ultrasound Transducer Sleeve and the Guidance Handpiece shaft and draws virtual representations of them in their spatial relationship, so that a physician can predict the Guidance Handpiece shaft's future path in relation to the features in the ultrasound slice. The Acessa Guidance System is considered an optional accessory to procedures where ultrasound is currently used for visualization, such as the Acessa System procedure.

The Acessa Guidance Handpiece is indicated for use in percutaneous laparoscopic coagulation and ablation of soft tissue, including treatment of symptomatic uterine fibroids under laparoscopic ultrasound guidance.

Acessa Guidance Handpiece (Model Number 5300): The Acessa Guidance Handpiece, when used with the tracking system, is meant to guide the tip of the Handpiece up to the uterine serosa. Once the device is advanced into the uterus, standard ultrasound views are used to guide the tip to the fibroid. Ultrasound visualization for fibroid penetration and treatment remain unchanged. The Acessa Guidance Handpiece is a single-use only, sterile, radiofrequency (RF) applicator that connects to the Acessa Generator by a custom Cable. The Handpiece consists of a handle with a trocar shaft, active needle tip, and seven deployable needle electrodes each with embedded thermocouple sensors for real-time temperature feedback. The Acessa Guidance Handpiece also has control buttons that allow the user to access the User Interface. This Acessa Guidance Handpiece also contains the magnetic guidance sensor used to determine spatial location. The embedded sensor and SROM can be used with the electromagnetic tracking technologies to track the positions of an Ultrasound Transducer and the Handpiece shaft, and draws virtual representations of them in their spatial relationship, so that a physician can predict the Handpiece shaft's future path in relation to the features in the ultrasound slice. These electromagnetic tracking technologies are considered optional accessories to Acessa System procedure.

The Acessa System is indicated for use in percutaneous, laparoscopic coagulation and ablation of soft tissue, including treatment of symptomatic uterine fibroids under laparoscopic ultrasound guidance.

The Acessa System includes the following system components: Generator (Model Number 1000): Provides RF energy to the Handpiece through the Handpiece Cable. Handpiece (Model Number 2000): Consisting of a disposable handle with a trocar-pointed shaft and 7 deployable needle electrodes. For use only disposable electrosurgical devices provided by Halt Medical, Inc. Handpiece Cable (Model Number 4200): Connects Handpiece to the Generator. This extension cable is provided with the Generator. Pads (Model Number 3000): A disposable set of 2 units, providing the return path for the RF energy applied by the Handpiece. Use only the Pads provided by Halt Medical, Inc. Pad Cable (Model Number 4300): Connects the Pads to the Generator. This extension cable is provided with the RF Generator. Power Cord (Model Number 4110): A medical grade power cord that provides AC power to the Generator. The Power cord is provided with the Generator. Foot Pedal (Model Number 4100): Pneumatic foot pedal with tubing used to turn RF energy on and off. The Foot Pedal with tubing is provided with the Generator. The Acessa System is designed to deliver up to 200 W of RF power at 460 kHz in three operational modes: Temperature Control, Manual Control and Coagulation Mode. A touch screen with a graphical user interface (GUI) enables selection of operational parameters such as the mode of operation, the ablation time, the target temperature, and the power delivery level. With the Handpiece placed in the tissue to be ablated and its electrodes deployed, RF power can be turned on. The system parameters are continuously monitored and displayed on the Generator. If the measured parameters are outside the acceptable limits, the RF energy delivery automatically stops and a message appears on the graphical user interface. RF energy during an ablation or coagulation can also be stopped at any time by the user by pressing the foot pedal. NOTE: The Acessa System must be used under laparoscopic ultrasound guidance. Laparoscopic ultrasound equipment is not included with the Acessa System.

The Halt 2000GI™ Electrosurgical Radiofrequency Ablation System is indicated for use in percutaneous, laparoscopic, and intraoperative coagulation and ablation of soft tissue.

The Halt 2000GI™ Electrosurgical Radiofrequency Ablation System includes the following system components: • Halt 2000GI Radiofrequency Generator (RF Generator): that provides RF energy to the RF Probe • Disposable RF Probe (Tulip™, TU 1000), a hand piece with a trocar-pointed shaft and 7 deployable RF needle electrodes. • RF Probe Extension Cable that connects the RF Probe to the RF Generator. • Dispersive Electrode Pads (TSP 115) Set that provides the return path for the RF energy applied by the RF Probe. (Use only Dispersive Electrode Pads provided by Halt Medical, Inc.) • Dispersive Electrode Pad Set Extension Cable (TSPCBL) that connects the Dispersive Electrode Pad Set to the RF Generator. • Power Cord that is a medical grade power cord providing AC power to the RF Generator. • Foot Pedal that is a pneumatic foot pedal with tubing used to turn RF energy on and off. The Halt 2000GI™ Electrosurgical Radiofrequency Ablation System is designed to deliver up to 200 W of RF power at 460 kHz in three operational modes: Temperature Control.
