It has already begun to push out software that will help EPs by automatically identifying some predefined arrhythmia patterns. It’s also in the process of improving the AcQMap catheter in ways that would allow it to provide real time data on tissue thickness, which would help EPs titrate the energy they deliver in the course of ablation based on the thickness of the tissue they’re ablating. The more use the system gets, the more feedback Acutus will have in improving it, and our impression from EPs is that the company has been very responsive in rapidly adding product features based on physician feedback.",
