Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A radiation coagulator having a radiation source which has a large infrared content disposed in a coagulator housing, further having a light conductor mounted in a holding tube attached to the housing and having a sleeve-like cap which is placed at the radiation exit end of the light conductor on the holding tube, with which cap a spot of tissue to be coagulated is brought into contact, and further wherein: the light conductor comprises a bundle of individual fibers; the holding tube is flexible; the sleeve-like cap is snapped onto the holding tube; and at least the region of the sleeve-like cap which comes into contact with the tissue spot to be coagulated comprises silicone rubber, said sleeve-like cap having a light exit window also comprising said silicone rubber.
Claim 2
Dependent Claim
129 words
A radiation coagulator having a radiation source which has a large infrared content disposed in a coagulator housing, further having a light conductor mounted in a holding tube attached to the housing and having a sleeve-like cap which is placed at the radiation exit end of the light conductor on the holding tube, with which cap a spot of tissue to be coagulated is brought into contact, and further wherein: the light conductor comprises a bundle of individual fibers; the holding tube is flexible; the sleeve-like cap is snapped onto the holding tube; and at least the region of the sleeve-like cap which comes into contact with the tissue spot to be coagulated comprises silicone rubber, said sleeve-like cap having a light exit window also comprising said silicone rubber.
