Company Overview

About Accuryn

Accuryn is a critical care hemodynamic monitoring system developed by Retia Medical, a medical device company headquartered in Ann Arbor, Michigan. The Accuryn Monitoring System provides continuous, real-time measurement of cardiac output, stroke volume, and fluid responsiveness in critically ill patients — parameters that are essential for guiding hemodynamic management in the intensive care unit (ICU) but historically required invasive pulmonary artery catheter (PAC) placement to measure. Retia Medical's proprietary pulse contour analysis algorithm enables continuous cardiac output monitoring using standard arterial line waveforms already present in most ICU patients, without requiring additional invasive access.

Business Model & Competitive Advantage

Accuryn has received FDA 510(k) clearance and is commercially available in US hospital ICU and high-acuity settings. The system integrates with existing patient monitors and electronic health record (EHR) systems, providing hemodynamic parameters in a format familiar to intensivists and anesthesiologists. The clinical value proposition centers on enabling individualized, goal-directed fluid therapy — using real-time cardiac output and fluid responsiveness data to guide IV fluid administration decisions — which evidence suggests can reduce complications from both under- and over-resuscitation in septic shock, post-surgical, and other critically ill patient populations.

Competitive Landscape 2025–2026

Retia Medical was founded to commercialize hemodynamic monitoring technology developed at the University of Michigan, with a focus on making advanced cardiac output monitoring accessible and non-invasive. The company has built clinical evidence supporting Accuryn's accuracy versus reference standard thermodilution cardiac output measurement. Accuryn competes with hemodynamic monitoring systems from Edwards Lifesciences (FloTrac/Acumen), LiDCO (now part of Masimo), and Deltex Medical in the non-invasive and minimally invasive cardiac output monitoring segment.
