Medtronic said on September 30 that Affera Prism-2 cardiac mapping software has FDA clearance and a CE mark. The software runs on the Affera mapping and ablation system with the Sphere-9 catheter. It builds three-dimensional maps of cardiac electrical activity during ablation. Medtronic lists magnetic and impedance-based tracking, beat matching, pace tagging and a pacing stimulator workflow.

A second item, the PulseSelect ProxBox adapter with proximity indicator software, got a CE mark only. It reads impedance to tell the operator how close the catheter sits to target tissue before energy goes in. Contact assessment is the weak point of pulsed field ablation next to RF, where temperature and impedance give an operator more to work with. PulseSelect was the first pulsed field ablation catheter FDA approved, and Medtronic's electrophysiology sales rose 29.5 percent year over year last quarter.
