DESCRIPTION
The Isolator™ Transpolar™ pen System is comprised of the AtriCure® Ablation and Sensing Unit (ASU) or Multifunctional Ablation Generator (MAG), Isolator™ Transpolar™ pen (Pen) or Isolator™ Long Pen TT (Pen), Footswitch, ASU Source Switch. The Pen is a single patient use electrosurgical instrument designed for use only with the ASU and ASU Source Switch (ASB) or MAG. The Pen is used to ablate cardiac tissues and as a surgical pacing and mapping tool. When the Pen is connected to the ASU or MAG, the generator provides the bipolar radiofrequency (RF) energy flowing between both electrodes of the Pen. The Operator controls the application of this RF energy by pressing the Footswitch. When the Pen is connected to an auxiliary pace, sense, or stimulation device; the Pen is designed to provide temporary pacing or monitoring. The ASB is a passive device accessory that allows switching between the ASU and an external pacing/monitoring device, such as the Oscor PACE 203 H temporary pacemaker.

PRECAUTIONS
- Read all instructions carefully for the AtriCure® ASU and ASB Switch Matrix or MAG, Isolator™ Transpolar™ Pen, and any auxiliary device being used prior to using the devices. Failure to properly follow instructions may lead to electrical or thermal injury and may result in improper functioning of the device.
- Use of the Pen should be limited to properly trained and qualified medical personnel.
- Proper surgical procedures and techniques are the responsibility of the medical professional. Understanding the proper use of the Oscor PACE 203 H temporary pacemaker equipment is also the responsibility of the medical professional.
- Each surgeon must evaluate the appropriateness of any procedure based on their own medical training and experience, and the type of surgical procedure.
- Patient and procedure selection is solely a medical responsibility and the outcome is dependent on many variables including patient pathology, and surgical and perfusion procedures.
- Variations in specific procedures may occur due to individual physician techniques and patient anatomy.
- To avoid damage to the device, do not drop or toss the Pen. If the Pen is dropped, do not use it. Replace with a new Pen.
- Do not use the Pen in the presence of flammable materials.
- Do not re-sterilize or reuse the Pen.
- The distal tip of the Pen must be kept clean of debris during surgery to avoid loss of power. Before activating the ASU or MAG, inspect the area at the distal tip of the Pen for foreign matter. Foreign matter captured on the tip will adversely affect the ablation.
- The Pen is only compatible with the AtriCure® ASU/ASB or MAG. Use of the Pen with another manufacturer’s generator may damage the device and result in patient injury.
- The ASB or MAG should only be used with FDA-approved cardiac pacing and sensing devices.
- Do not use the Pen for coagulation or ablation of veins or arteries.
- Use caution to avoid trauma to tissues not within the target area of ablation. Tissue and/or structures behind the targeted tissue should be protected from potential thermal spread.
- The Pen has an eight-hour useful life that is tracked by the ASU or MAG. If you attempt to plug in a device that has reached its time limit expiration, the Pen will no longer function and the ASU or MAG will display a message indicating that the Pen must be replaced.
- It is the responsibility of the user to dispose of this device in accordance with local regulations.
- Excessive bending of the malleable stainless steel shaft will cause the shaft to harden and may increase the potential for breakage.
INSTRUCTIONS FOR USE
CARDIAC ABLATION MODE
- Using a sterile technique, remove the Pen from its packaging. With the Connector Alignment Arrow symbol in the 12 o’clock position, push the Connector into the Pen receptacle on the front of the ASU/ASB or MAG. Verify that the connections between the Pen and the ASU or MAG are secure. If the connections are loose, do not use the Pen. Inspect the Cable and do not use the Pen if the cable is frayed or the insulation is damaged.
- Under direct visualization, place the distal tip against the targeted cardiac tissue. Assure both electrodes are in contact with targeted tissue.
- Painting ablation technique:
- Maintaining visualization, move the distal tip gently across the targeted cardiac tissue.
- While maintaining continuous contact between the tissue and the electrodes, move the device continuously in an oscillating manner at a rate of approximately 1 cm/sec.
Painting Lesion Depth
20 seconds 2 cm oscillation
2.0 – 4.0 mm
Data was obtained from ablations performed on excised bovine myocardium and represented 95% confidence intervals. Results may vary based on live tissue properties.
Stamping ablation technique:
-
* Apply constant firm pressure to the tissue without movement. Maintain full contact of the electrode surface with the tissue. A stamping lesion is approximately 8 mm x 6 mm.
- If creating longer linear lesions with the Stamp technique, overlap the contiguous ablations by 50% to ensure a continuous and complete lesion.
Stamp Lesion Depth
10 Seconds | 15 Seconds |
---|---|
3.3 – 3.8 mm | 3.8 – 4.4 mm |
Data was obtained from ablations performed on excised bovine myocardium and represented 95% confidence intervals. Results may vary based on live tissue properties.
- Press the Footswitch to activate the ASU or MAG.
- When the Footswitch is pressed, the ASU or MAG will emit an audible tone indicating that current is flowing between the electrodes located at the distal tip of the Pen and through the tissue.
- Inspect the surgical area to ensure adequate ablation.
- Between ablations, wipe the distal tip clean with a saline-soaked gauze pad. Important: For optimal performance, keep the Pen electrodes clear of coagulum. To ensure the electrodes are clear of coagulum:
- Use saline-soaked gauze to clean the electrodes after each ablation. The coagulum is much easier to remove within the first several seconds after ablation. In a brief period of time, the coagulum may dry, making the removal of the coagulum more difficult.
- Check both electrodes before each ablation to ensure that the gold of the electrode is visible and the coagulum is removed.
- If the Pen is idle between ablations, place the Pen distal tip onto saline-soaked gauze to prevent any coagulum not cleaned off the electrodes from drying.
- Repeat ablation if necessary.
- Upon completion of the surgical procedure, disconnect the Pen from the generator and discard the Pen after use. Follow local governing ordinances and recycling plans regarding disposal or recycling of device components.
PACING AND MAPPING MODE
- Inspect the package and product to ensure the expiration date has not passed and no damage occurred to the product during shipping and handling.
- Using a sterile technique, remove the Pen from its packaging.
- With the Connector Alignment Arrow symbol in the 12 o’clock position, push the Connector into the Pen receptacle on the front of the ASB or MAG. Verify that the connections between the Pen and the ASB or MAG are secure. If the connections are loose, do not use the Pen. Inspect the Cable and do not use the Pen if the cable is frayed or the insulation is damaged.
- A cable with standard 0.080-inch pin tip plugs is provided with the ASB or MAG to connect to the auxiliary device. The end of the cable with the single pin tip plug is connected to the ASU Source Switch or MAG. The end of the cable with dual pin tip plugs is connected to the auxiliary device.
- Turn on the temporary pacing or sensing equipment and ensure proper connections to validate electrical continuity. For detailed instructions refer to the temporary pacemaker manual.
- Settings and procedures for the auxiliary device are determined according to the instructions for use provided with the auxiliary device. Set the auxiliary device to atrial asynchronous mode (sensing disabled or increased to maximum value).
- Note: The Pen will pace when the auxiliary device is in the ON position.
- Identify and expose the sites for pacing and sensing using standard surgical techniques. Under direct visualization, place the electrodes against the targeted tissue. Assure both electrodes are in contact with the targeted tissue.
- Ensure the pacing is only on when the end effector is in contact with the targeted tissue. The device will pace when the auxiliary device pacing is on.
- For sensing (mapping), place the distal tip onto the targeted tissue to display the electrogram (EGM).
- Upon completion of the surgical procedure, disconnect the Pen from the ASU/ASB or MAG and discard the Pen after use. Follow local governing ordinances and recycling plans regarding disposal or recycling of device components.
