StarBurst® XL RFA Device

Its real-time, multi-point temperature feedback system ensures sustained target temperatures during the procedure. The patented temperature based end point provides predictable volumes of ablation with low local recurrence rates. Needle track ablation, adjustable array size, and temperature based technology of the revolutionary, first-generation StarBurst XL RFA electrode assures a high level of confidence that coagulative necrosis is taking place throughout the targeted radiofrequency interstitial tissue ablation.

StarBurst® Semi-Flex RFA Device

The StarBurst Semi-Flex RFA electrode is a versatile device that features both rigid (metal) and flexible (polymer) trocar sections. Its ability to bend up to 90 degrees in all directions enables easy gantry entrance for MRI and CT systems. This teaming of innovative needle design with imaging systems compatibility allows the StarBurst Semi-Flex RFA electrode to be used in percutaneous image-guided procedures. With multiple spherical ablation size capabilities of up to 5 cm in diameter at 1 cm increments, the Semi-Flex covers a broad spectrum of applications.

Important Risk Information

INDICATION FOR USE: The StarBurst XL Electrosurgical Device is a tool to transmit monopolar radiofrequency energy (provided by the Model 1500X RF Generator) and is indicated for use in percutaneous, laparoscopic, or intraoperative coagulation and ablation of soft tissue including the partial or complete ablation of non-resectable liver lesions and palliation of pain associated with metastatic lesions involving bone in patients who have failed or are not candidates for standard pain therapy. CAUTION: Federal (USA) law restricts these devices to sale by or on the order of a physician. CONTRAINDICATIONS: None known. WARNINGS AND PRECAUTIONS: For single use only. Do not bend or kink the trocar or the needles; do not attach anything (i.e., clamps, etc.) to the Device, or use metal introducers that do not have insulation; inadvertent patient injury may result. To ensure safe and effective use follow the manufacturer’s directions and recommended practices for the preparation, placement, surveillance, removal and use of the dispersive electrode. To achieve the desired ablation follow the manufacturer’s guidelines of ablation time and temperature. Ensure that the device is placed at least 1 cm away from structures not intended for ablation. In laparoscopic procedures, care must be taken to avoid a gas embolism, and activation of the device when not in contact with target tissue may cause capacitive coupling. In some cases, a liver lesion will only be partially destroyed; the final determination of the success of lesion destruction can only be made by imaging studies following the procedure and during regular long-term follow-up. For ablation of painful bone metastases, do not perform RF ablation in weight-bearing bone with evidence of impending fracture. Pathologic fracture is more prevalent and serious in long bone. Please see package insert for complete list of warnings and precautions. POTENTIAL COMPLICATIONS: Published reports on the use of the RFA system indicate low overall complication rates. These include bleeding, abscesses and, in cases involving the treatment of bone tumors, fractures and nerve damage.

Indications, contraindications, warnings and instructions for use can be found in the instructions for use supplied with each device. Observe all instructions prior to use. Failure to do so may result in patient complications.
