    Patent number: 5505686
    Abstract: An endoscope including an elongated endoscope body sized and adapted for insertion into a passage, such as a passage of the body of a patient. Optical components are carried by the endoscope body to enable viewing of the passage distally of the distal end of the endoscope body within a field of view of the endoscope. An elongated, resilient member is mounted on and carried by the endoscope body such that the endoscope body and the resilient member are a unitary assembly which can be inserted as a unit into the passage. The resilient member extends beyond the distal end of the endoscope body and is capable of contacting material within or forming the passage and relatively displacing the distal end of the endoscope body and such material within the field of view of the endoscope to enhance viewing of the passage with the endoscope.
