Abstract

The disclosure is directed to a device for coagulating biological tissue by applying heat to the same. The device has a cooling arrangement by means of which the heating leading end portion which contacts and coagulates the tissue, can be cooled upon completion of the coagulation so that it can be safely withdrawn without causing damage to non-coagulated tissue which it may contact during the withdrawal.
