contact force sensing
Catheter technology providing real-time measurement of tip contact pressure against tissue during ablation.
Full Definition
An advanced catheter technology that provides real-time feedback on the contact force between the catheter tip and cardiac tissue during ablation procedures. Contact force sensing enables operators to optimize lesion formation by maintaining adequate tissue contact while avoiding excessive pressure that could cause perforation or char formation. The technology typically displays force measurements in grams, with target ranges varying by anatomic location and ablation strategy. Proper documentation includes force measurements, force-time integrals, and correlation with impedance and temperature data.
Usage
Usage note: Include specific force measurements and ranges in procedural documentation.
