At Attune Medical®, we’re focused on three crucial pillars: clinical needs, the state of science, and, most importantly, patient safety. Our journey began with a vision to enhance temperature regulation with proactive esophageal cooling and targeted temperature management. We proudly pioneered the first and only FDA-cleared temperature regulation device for esophageal protection during cardiac ablation procedures- ensoETM®.

What Sets Us Apart

EnsoETM is a groundbreaking approach to temperature management. This novel technology simplifies esophageal cooling and targeted temperature control with a user-friendly, closed-loop system. Designed for ease of use, it seamlessly integrates with existing heat exchangers, making it a go-to choice for medical professionals.


At Attune, our mission is to improve patient safety and outcomes while reducing costs through innovative products and solutions.


At Attune, we aspire to provide patient-centered solutions through targeted temperature management and proactive esophageal cooling.
