OSK Thermocouple Used in a Renal Denervation (RDN) Procedure

A thermocouple supplied by OSK was used in a clinical renal denervation (RDN) procedure as a component of a device supplied by a project partner. This marks a milestone for OSK in supplying temperature-sensing components for medical devices.

The role of the thermocouple

RDN is a catheter-based procedure that targets sympathetic nerves around the renal arteries. In this project, the thermocouple serves as a temperature-sensing component. The device design determines the sensing location, sampling method and use of the temperature signal.
