Abstract
An endoscopic device is disclosed which provides for unobstructed viewing within a body space of a patient. The endoscopic device includes a tube carrying a light transmitting system with a balloon extending over the system. The balloon can be expanded and the interior of the body space inspected or irradicated with a laser beam through the balloon.
Claims24
An endoscopic device for use in a body space comprising:
- (a) an elongated tube having a distal portion;
- (b) an expandable balloon carried on exterior of the distal portion of the tube, the balloon being substantially transparent when expanded;
- (c) a fluid passageway in fluid communication with the expandable balloon;
- (d) an optic system carried by the tube and terminating within the expandable balloon;
- and
- (e) a hose carried by the tube and extending beyond the distal portion of the tube and through the expandable balloon to be in fluid communication with the body space distally of the balloon;
- whereby the distal portion of the endoscopic device can be inserted into the body space and fluid introduced through the fluid passageway to expand the expandable balloon.

An endoscopic device for use within a body space of a patient, the device comprising:
- (a) an elongated tube having a distal end;
- (b) an expandable balloon sealingly mounted about the periphery of the tube adjacent the distal end and extending over the distal end, the expandable balloon being substantially transparent when expanded and constructed of a material which can transmit laser irradiation without being substantially damaged;
- (c) a fluid passageway carried by the tube in fluid communication with the expandable balloon;
- (d) a viewing system carried by the tube and terminating within the expandable balloon;
- and
- (e) a laser light transmitting fiber carried by the tube and terminating within the expandable balloon;
- whereby the distal end of the device can be received within the body space and the expandable balloon expanded to contact the body space walls such that the inside of the space can be inspected and subjected to laser irradiation.
