Abstract: The invention relates to a system for predicting the viability of a body tissue in a patient. The system comprises a computing device, and a first pressure measuring device for measuring local perfusion pressure in the body tissue of the patient. This measuring device is connected to the computing device. A second pressure measuring device is provided for measuring the systemic perfusion pressure of the patient, said second pressure measuring device being connected to the computing device. A feedback indicator is connected to the computing device and is adapted to indicate the viability of the tissue calculated by the computing device on the basis of the measured local and systemic perfusion pressures. The invention also includes a method of predicting the viability of the body tissue and to the first pressure measuring device.

Abstract: A method is described for testing the viability of a tissue of a patient for an anastomosis using a perfusion measuring device wherein the method may comprise: controlling at least one actuating structure of the perfusion measuring device to rapidly ramp up a force exerted on at least one test area of the tissue selected for an anastomosis, the force exerted on the at least one test area defining a local (systolic) perfusion pressure; and, during the ramp up of the force, the computer receiving a sensor signal from at least one sensor of the perfusion measuring device and a signal from a blood pressure device, the sensor signal being indicative of perfusion of blood through the micro vascularization in the first test area and the blood pressure signal being indicative of a general (systolic) blood pressure of the patient; controlling the first actuating structure to slowly ramp down the force exerted on the first test area, when the sensor signal signals the computer that the perfusion of the blood in the tis
