Patent ID: 7977658

Claim:
A contact-type, endoscopic infrared coagulation apparatus for delivering infrared energy to human or animal tissue, comprising: a source of non-coherent, multiple wavelength, visible and infrared radiation which is not a laser with an ellipsoidal reflector which focuses the radiation at a secondary focal point; an elongated, highly flexible fiber optic member which can be used in a retroflexed position, the member having a multicomponent transparent fiber bundle capable of transmitting radiation from the source from a proximal end of the member to a distal end of the member, the distal end having a contact portion defining a radiation delivery area from the member to tissue in contact with the delivery area, an outer compression sheath being provided over the multicomponent transparent fiber bundle; a connector on the proximal end of the elongated member for quickly connecting the member to and disconnecting the member from the apparatus where the member is aligned for receiving visible and infrared radiation from the source; wherein the elongated member has a length of at least 60 cm and at least the distal end of the elongated member has an outer diameter less than 4.2 mm and the outer compression sheath is formed of a friction-minimizing material enabling removable insertion of the elongated member in a channel of an endoscope until the contact portion of the distal end of the elongated member exits a distal end of the endoscope for contacting tissue to be treated.
