What Attune Medical does
Attune Medical is a Chicago-based, private medical device company founded in 2009 that developed the ensoETM system, a thermal regulating device providing esophageal protection through proactive cooling during radiofrequency (RF) cardiac ablation procedures. The device operates as a closed-loop water circulation system, functionally similar to an orogastric tube, that circulates chilled water through the esophagus to mitigate ablation-related thermal injury — addressing a specific clinical risk in atrial fibrillation treatment, namely atrioesophageal fistula (AEF) and severe esophageal lesions. The system has an FDA-granted indication to reduce the likelihood of ablation-related esophageal injury, and is offered in two catalog configurations (ECD01-A compatible with Gaymar Medi-Therm III and Stryker Altrix; ECD02-A compatible with Gentherm Blanketrol II/III), enabling integration with the installed base of third-party temperature control units.
The company serves hospitals and cardiac ablation centers as its primary customer segment, targeting electrophysiology labs performing RF ablation. Clinical evidence supporting adoption includes a retrospective review of 25,186 RF ablations across 30 hospitals (14,224 ensoETM patients vs. 10,962 LET-monitoring patients), reporting zero AEF cases with ensoETM versus a 0.146% rate with LET monitoring, an 83.4% relative reduction in thermal injury, a 100% per-protocol reduction in severe esophageal lesions, a 14% absolute increase in freedom from atrial arrhythmia at one year, a 36–60 minute reduction in mean procedure time, and a 43% relative increase in lab throughput. Attune Medical distributes the ensoETM system through a licensing/commercialization partnership with Haemonetics' Hospital Solutions division, leveraging Haemonetics' direct hospital sales force, catalog ordering, and multilingual product pages (English, French, German, Italian, Japanese, Russian, Spanish, Chinese) to reach global accounts.
The company is funded by approximately $24 million across five disclosed equity rounds between 2014 and 2018, with investors including Gopher Angels, Heartland Angels, Praetidian Financial Group / Praetorian Financial Group, and TWB Investment. Headcount is 11–50 employees, with leadership comprising Jay Istvan (CEO), Erik Kulstad (Co-founder & CMO), Igal Ladabaum (Chairman), and Patrick Shanley (COO). Pricing is not publicly disclosed. The broader patient warming / targeted temperature management market is projected to reach $3.37 billion by 2030 at an 8.8% CAGR, providing the macro tailwind for the company's core use case.

Attune Medical product offering
Product offeringCore offering
Attune Medical manufactures and sells the ensoETM® System, a single-use thermal regulating device that provides esophageal protection through proactive cooling during radiofrequency (RF) cardiac ablation procedures. The device operates as a closed-loop water circulation system, akin to an orogastric tube, that connects to standard hospital temperature control units to chill and circulate water around the esophagus. It carries an FDA-granted indication to reduce the likelihood of ablation-related esophageal injury, and is sold in two catalog models compatible with major temperature control units used in hospitals.
