1. An endoscope for the gastrointestinal tract, comprising:
- a) a flexible elongate member comprising a proximal end and a distal end, the flexible elongate member further comprising a guide tube having an opening adjacent the distal end projecting at an oblique angle relative the longitudinal axis of the flexible elongate member;
b) a visualization device and light source positioned adjacent the distal end of the flexible elongate member;
c) a working channel extending between the proximal and distal ends of the flexible elongate member adapted to receive medical instruments, the working channel comprising an opening adjacent the distal end of the flexible elongate member; and
d) a guide wire slidably received by the guide tube, the guide wire positioned between the proximal and distal ends of the flexible elongate member and extending distally relative the flexible elongate member to form a loop disposed distally relative the flexible elongate member, the guide wire being longitudinally moveable relative the flexible elongate member to vary the size of the loop.

Abstract
A medical device for performing medical procedures inside a lumen (such as the GI tract) of a patient is provided. The device includes an elongate flexible member which can be advanced along a track. The track can include a loop portion which can be advanced ahead of the elongate flexible member. The distal end of the flexible member can include a camera, light source, vacuum opening, and a working channel for receiving medical instruments.

16. An endoscope, comprising:
-
a) a flexible elongate member comprising a proximal end and a distal end; b) a visualization device and light source positioned adjacent the distal end of the flexible elongate member; c) first and second guide tubes each having an opening adjacent the distal end of the flexible elongate member, the guide tube openings project distally at an oblique angle relative the longitudinal axis of the flexible elongate member; and d) a guide wire received in the first and second guide tubes and extending from the openings to form a loop disposed distally relative the flexible elongate member, the guide wire being independently slideable in the first and second guide tubes to adjust the size of the loop. - View Dependent Claims (17, 18)
