Abstract

An endoscope accessory, such as a coupler device, is provided that includes a main body with a visualization section for allowing viewing of tissue by the endoscope and a proximal end configured for attachment to a distal end portion of the endoscope. The device includes a passage within the main body having an open distal end and a proximal end aligned with the working channel of the endoscope. A locking element on the coupler device secures an angle of exit of an instrument passing through the passage.

Claims (14)

1. A device for use with an endoscope having an elongate shaft with an internal working channel, the device comprising:

a sheath;

a main body comprising a visualization section for allowing viewing of tissue by the endoscope and a proximal end configured for attachment to a distal end portion of the endoscope;

a passage within the main body having an exit portal and a proximal end configured for alignment with the working channel of the endoscope;

a flexible membrane in contact with, and coupled to, an outer surface of the main body and at least partially surrounding the exit portal; and

wherein the device is configured such that an instrument passing through the passage is capable of angular adjustment relative to the main body by actuation of the endoscope.

2. The device of claim 1 , wherein the passage comprising a working channel extension within the main body.

3. The device of claim 2 , wherein the working channel extension is flexible and capable of angular adjustment by actuation of the endoscope.

4. The device of claim 1 , wherein the proximal end of the passage is configured for insertion into the working channel of the endoscope.

5. The device of claim 1 , wherein the main body of the device is configured to accommodate therein an elevator for angular adjustment of the instrument.

6. The device of claim 1 , further comprising a mechanism for articulating an instrument passing through the passage.

7. The device of claim 1 , wherein the main body comprises an elastic or elastomeric material.

8. The device of claim 1 , wherein the endoscope is a side-viewing scope.

9. The device of claim 1 , wherein the endoscope includes an elevator for angular adjustment of the instrument.
