It also is intended for coagulation and ablation of tissue in bone during surgical procedures, including palliation of pain associated with metastatic lesions involving bone in patients who have failed or are not candidates for standard therapy. The system contains an RF generator, peristaltic pump, and the connector hub, which provides two channels for the use of the OsteoCool™ RF ablation probes and two channels for use of the OsteoCool™ independent thermocouples. The OsteoCool™ RF ablation probe uses a coaxial, bipolar technology that delivers localized tumor ablation and automatically moderates power to keep RF heating within the desired treatment range, reducing risks of potential thermal damage to adjacent structures. The active tip of the RF ablation probe is internally cooled with circulating water. RF energy heats the tissue while circulating water moderates the temperature in close proximity to the active tip. This combination creates large volume lesions without excessive heating at the active tip. The OsteoCool™ RF ablation probes are sterile and intended for single use. The OsteoCool™ Bone Access Kit is a single-use device intended to contact body tissues. Do not reuse, reprocess, or resterilize. The OsteoCool™ independent thermocouple is for optional temperature monitoring at or near the site of ablation. A physician using this equipment must be familiar with bony anatomy, imageguided procedures, and bone access techniques. Refer to the OsteoCool™ Instructions for Use for complete generator and pump setup. Important This guide does not replace the information in the Instructions for Use provided with the components of the OsteoCool™ RF Ablation System, OsteoCool™ RF Ablation Probes, OsteoCool™ Bone Access Kits, and the OsteoCool™ Independent Thermocouple. The Instructions for Use includes important information such as warnings, precautions, contraindications, and troubleshooting. It is important to read the Instructions for Use and these precautions carefully prior to device operation. Additional help information can be accessed through the “help” button located on the generator screen. The system may be mounted on a rolling cart or a desk stand (see following instructions).

Note: For access to other areas of bone, a supine or lateral patient positioning may be more effective for gaining appropriate access. 2. Using appropriate image guidance, confirm the target location for treatment and proceed with the necessary skin incision(s). OSTEOMAP TECHNIQUE USING BONE ACCESS KITS — SPINE 1. Insert the stylet into the cannula to form the osteointroducer. 2. Using fluoroscopic image guidance, insert the osteointroducer at the desired site. 3. Using manual control and appropriate image guidance, advance the osteointroducer through the soft tissues into the selected bone to the desired depth. 5. While holding the cannula, rotate the handle 180 degrees counterclockwise to remove the stylet. Proceed with the OsteoCool™ precision drill. 4. A surgical mallet may be used to augment the insertion of the osteointroducer. For bi-pedicular ablation, repeat the steps above. 6 Note Markings on the cannulas should be used as reference marks only. They are not intended to replace the use of fluoroscopic observation. Note The OsteoCool™ osteointroducer offers an internal stylet that extends beyond the distal end of the cannula. This design is intended to provide a visual indication under image guidance of where the posterior margin of the ablation zone with the OsteoCool™ RF ablation probe will stop. 7 Caution To maintain structural integrity, do not advance the cannula without the stylet fully inserted. OSTEOMAP TECHNIQUE USING BONE ACCESS KITS — SACRUM, ILIAC, AND ACETABULUM SACRUM One-probe approach: 1. Insert the stylet into the cannula to form the osteointroducer. 2. Using CT or fluoroscopic image guidance, insert the osteointroducer at the desired site. 3. Using manual control and appropriate image guidance, advance the osteointroducer through the soft tissues into the selected bone to the desired depth. 4. A surgical mallet may be used to augment the insertion of the osteointroducer. 5. W hile holding the cannula, rotate the handle 180 degrees counterclockwise to remove the stylet.

USE OF THE PRECISION DRILL — SPINE 3. Read the color marking on the proximal end of the drill to aid in probe selection. If the drill positioning is in between color markings, advance or retreat to a color marking. Select the probe size that corresponds with the color marking. 1. After gaining access to the vertebral body using the osteoinducer, advance the precision drill down the cannula lumen into the vertebral body. 2. Using manual control and image guidance, rotate clockwise and advance the precision drill to the desired depth. This depth will serve as the anterior boundary for the ablation zone. Note Markings on the drill should be used as reference marks only. They are not intended to replace the use of fluoroscopic observation. Note The color markings on the proximal shaft of the OsteoCool™ precision drill correlate with sizes of the OsteoCool™ RF ablation probes. 4. Remove the precision drill from the cannula lumen using clockwise rotation. The target site is now ready for ablation probe placement. For bi-pedicular ablation, repeat the steps above. Product testing recommends a distance of 8–10 mm between the distal tips of the probes to yield the largest ablation zone. 12 13 USE OF THE PRECISION DRILL — SACRUM, ILIAC, AND ACETABULUM Note The color markings on the proximal shaft of the OsteoCool™ precision drill correlate with sizes of the OsteoCool™ RF ablation probes. 1.

Put the burette into the pump unit’s burette holder. Warning DO NOT over tighten the connection. Maintain sterility of the tubing’s inner pathway so if water is spilled in the sterile field, sterility will not be compromised. 1. Pass the tubing and electrical connections on the probe out of the sterile field. 3. Open the pump head lid and thread the thicker tubing from the bottom of the burette into the pump head tube holder. 2. Remove the caps on the male and female luer locks for both the tube kit and the chosen probe. Connect the appropriate luer lock on the tube kit to the corresponding luer lock on the probe. 4. Ensure that the tubing is properly placed between the notches and along the center channel beneath the pump head. Warning Improper positioning of the tubing can pinch the tube and restrict water flow. 5. Close the lid to hold the tubing in place. Leave the luer lock caps on the tubing until you are ready to connect the probes, so the inner pathway of the tube kit remains sterile. Open lid Closed lid holds tubing in place 18 19 CONNECTING TO THE CONNECTOR HUB PERFORMING RF ABLATION — SPINE The connector hub provides two channels for the use of the ablation probes and two channels for use of the independent thermocouples. 1. The ablation probes come with a preassembled spacer. Discard or keep the spacer, based on the bone access tool used. Reference chart below: The white ports (top) accept the RF ablation probes. The black ports (bottom) accept the independent thermocouples. 1. Connect the male connector on the ablation probe to the female connector on the connector hub. 2. Confirm via on-screen information that the probe has been detected and is ready for use. Note The generator will quickly detect the probe and indicate a “High Impedance” error while the probe is outside of tissue. When the probe is placed in tissue, the “High Impedance” error will disappear. Warning Never force the probe if you feel significant resistance.

Allow the generator to complete the ablation, monitoring for error signs on the generator screen. A3 a. The ablation will terminate automatically as soon as the set ablation time is reached. 6. After the ablation is complete, remove the probe from the cannula and detach from the tube kit. Discard as biohazardous waste. Detach the tube kit from the generator and discard as biohazardous waste. 7. The OsteoCool™ bone access cannula is still in place and ready to accept other instrumentation. B3 C3 22 23 OPTIONAL TRACK RF ABLATION 1. To ablate the track, select “Retract” on the generator screen. Two-probe approaches: 2. Press the RF power button. 3. The screen will signal when the track ablation starts. 4. Slowly pull back on the RF ablation probe and cannula simultaneously (approximately 1–2 mm/second) or pull back and track ablate while stationary. When the desired end point for track ablation is reached, press the RF power button to stop RF delivery. A4 Warning Track ablation is the use of uncooled RF ablation during which time the peristaltic pump is not circulating water. Ablating the track all the way to the skin can result in skin burns. It is recommended to end the track ablation prior to this point. B4 C4 24 25 OPTIONAL TEMPERATURE MONITORING WITH THE INDEPENDENT THERMOCOUPLE The independent thermocouple provides real-time temperature information to gauge ablation zone margins and help prevent thermal damage to adjacent critical structures. The temperature detected by the independent thermocouple is displayed on the generator screen. BONE ACCESS FOR SUBSEQUENT PROCEDURES GENERAL SAFETY GUIDELINES For desired tissue heating and anatomical access: Avoid advancing the probe into bone tissue without first using the introducer and drill to create a clear channel for the probe. Forcing the probe through bone tissue may cause damage to the probe. The bone access can be used for subsequent physiciandirected procedures such as cementoplasty, sacroplasty, vertebroplasty, or kyphoplasty. Confirm such procedures are compatible with the OsteoCool™ Bone Access Introducer length and gauge. 1. Insert the thermocouple into the provided introducer. 2. Connect the male connector on the thermocouple to the female connector on the connector hub. 3. Confirm via on-screen information that the thermocouple (sensor) has been detected. 4. Access the site. Place the thermocouple in the tissue to be monitored. PERFORMING RF ABLATION USING CUSTOM SETTINGS The OsteoCool™ system generator screen includes the ability to change procedure settings. These settings should only be adjusted by physician experts in RF ablation. To access the custom settings on the generator, complete the following steps: 1. Press the “Settings” button. 2. Select “Procedure Settings.” 3. Edit settings based on procedural need. Each probe can be individually adjusted by time, temperature, power limit, ramp rate, and impedance cut off. Additionally, each independent thermocouple sensor can be individually adjusted by temperature. 4. Once desired settings have been achieved, press the “X” button to return to the generator’s home screen user interface.
