Cardioblate

Summary

Mapping, Ablation, Pacing, and Sensing

The Cardioblate^® MAPS Device integrates cardiac rhythm diagnostics and surgical ablation technologies in one simple-to-use device.

Map:  Stimulate

Apply high frequency stimulation (HFS) to areas around the pulmonary vein/atrial junction to identify sites that may contribute to various cardiac arrhythmias.

Ablate:  Target Sites

Destroy those sites identified through HFS. Destruction of these sites eliminates a potential source of various cardiac arrhythmias.

Pace

Lesion Assessment: Pacing

• Establish atrial capture by pacing from the area to be isolated.
• Once the isolation lesion has been created, pace with the Cardioblate MAPS device from the same location as before to attempt atrial capture.
• Conduction block is proven if atrial capture is not obtained (no corresponding atrial rate change as established initially).

Sense

Lesion Assessment: Sensing

Monitor atrial electrogram (EGM) pre- and post-ablation to confirm entrance block.

• Before creating the isolation lesion, monitor atrial EGM in the area to be isolated.
• After the lesion has been created, monitor atrial EGM on both sides of the lesion for comparison to each other and those measured previously.
• Conduction block is proven by absence or reduction of electrical activity in the area isolated by the ablation lesion when compared to atrial activity outside that area.
