Method for producing a heating device having a heating profile for medical instruments and a heating device produced by that method

A method for producing a heating device which covers and controls a temperature of a medical instrument, the method comprising the steps of:

• a) preparing a heating profile from an elastic material, the heating profile having at least one cavity which extends along an axial extension thereof and which can be accessed from an outside for insertion of the medical instrument and with at least one axial bore which extends along an entire length of the heating profile, the at least one axial bore having an axial bore diameter;
• b) selecting a temperature control element, the temperature control element having an outer surface with an outer surface diameter that is larger than the axial bore diameter;
• and
• c) inserting, following steps a) and b), the temperature control element into the axial bore of the heating profile, thereby widening the axial bore, wherein the widened axial bore presses inwardly in a substantially radial direction against the outer surface of the temperature control element thereby establishing good thermal contact between the temperature control element and the heating profile.
