摘要
The present application provides systems that include a controller, and an insertion device with at least one temperatures sensor thereon and a pump coupled to the controller. The insertion device provides temperature measurement(s) at/of a subject's organ to the controller and the controller varies an infusate flow rate to induce temperature changes in at least a portion of the subject's organ and stores the temperature measurements during perfusion induced temperature changes on a memory device. The controller may estimate at least one hemodynamic characteristic of at least a portion of the subject's organ based on the temperature measurements obtained during perfusion induced temperature changes.
