INSTRUCTIONS FOR USE

Cardiac Ablation Mode

Using 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 or ASB. Verify

that the connections between the Pen

and the ASU 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:

3.1. Maintaining visualization, move

the distal tip gently across the

targeted cardiac tissue.

3.2. 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.

2.0 – 4.0 mm

*Data was obtained from ablations performed on

excised bovine myocardium and represent 95%

confidence intervals. Results may vary based on

live tissue properties.

Stamping ablation technique:

4.1. 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.

4.2. If creating longer linear lesions

with the Stamp technique,

overlap the contiguous ablations

by 50% to ensure a continuous

and complete lesion.

properties.

Press the Footswitch to activate the

ASU.

When the Footswitch is pressed, the

ASU 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:

8.1. 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

removal of coagulum more

difficult.

8.2. Check both electrodes before

each ablation to ensure that the
