Working Heart Upgrade for IH-5 Core System

The IH-5 Langendorff System can be upgraded to a fully-ejecting working heart model for physiological cardiovascular studies, e.g., cardiac function and metabolism. The upgrade allows rapid and easy switching between working heart (ejecting heart) and Langendorff modes.

To upgrade an IH-5 Langendorff Core System to an IH-5 Working Heart System, add a Working Heart Upgrade and one of the species-specific atrial cannulae. To measure flow, a TTFM-2 flowmeter and species-suitable flow probe are also required.

To ensure that your system is properly configured as a functional unit that meets your application needs, please complete our Checklist and contact Technical Services before placing an order. In Europe, please call +49 7665-9200-0 or email For other regions, call 800-547-6766 or email
