Abstract
The present disclosure relates to the field of medical devices. Specifically, the present disclosure relates to devices, systems and methods for extending a working channel of an endoscope, such as for delivery of a stent.
Claims20
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.
3 more elements
An extension system, comprising:
- an endoscope having a working channel;
- a delivery device having;
- a shaft extending distally from the delivery device and receivable within the working channel;
- and
- 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 the delivery device;
- and
- a distal connector at a distal end of the inner member configured to connect to a proximal end of the endoscope.
8 more elements
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.
