DEVICES AND METHODS FOR EXTENDING A WORKING CHANNEL
First Claim
Patent Images
1. An extension device, comprising:
- a tubular inner member including a lumen extending therethrough;
a tubular outer member including a lumen extending therethrough, the lumen of the outer member configured to receive the inner member, the outer member and inner member slidable relative to each other in a telescoping fashion to a desired position that corresponds to an adjustable length of the extension device;
a locking assembly configured to fix the outer member and the inner member with respect to each other at the desired position;
a proximal connector at a proximal end of the outer member configured to connect to a distal end of a first medical device; and
a distal connector at a distal end of the inner member configured to connect to a proximal end of a second medical device.

17. A method of extending a length of a working channel, comprising:
-
inserting an endoscope having a working channel into a patient; inserting a catheter into the patient through the working channel; placing an extension device having a lumen extending therethrough about a shaft of the catheter; attaching the extension device to a proximal end of the working channel; attaching the catheter to a proximal end of the extension device; adjusting the extension device to a desired position that corresponds to an adjustable length of the extension device; and locking the extension device at the desired position. - View Dependent Claims (18, 19, 20)
