Abstract
The present disclosure relates to the field of medical devices. In particular, the present disclosure relates to devices with a shaft having an effective working length that is adjustable relative to a connector of the device and/or a working channel of an endoscope, and methods for their use, such as devices and methods for delivery of a stent.
Claims20
A device, comprising:
- a tubular distal member including a lumen extending therethrough;
- a tubular extension member including a proximal end, a distal end and a lumen extending therethrough, the distal end disposed about the distal member;
- a tubular proximal member including a lumen extending therethrough;
- and
- a shaft extending distally from the tubular proximal member;
- wherein the proximal member is slidingly disposed within the proximal end of the extension member and adjustable in a telescoping fashion to a desired position that corresponds to an adjustable effective working length of the shaft.

A system, comprising:
- an endoscope having a working channel;
- and
- a device, comprising:
- a tubular distal member including a lumen extending therethrough;
- a tubular extension member including a proximal end, a distal end and a lumen extending therethrough, the distal end disposed about the distal member;
- a tubular proximal member including a lumen extending therethrough;
- and
- a shaft extending distally from the proximal member and receivable within the working channel;
- wherein the proximal member is slidingly disposed within the proximal end of the extension member and adjustable in a telescoping fashion to a desired position that corresponds to an adjustable effective working length of the shaft.
6 more elements
A method of treating a patient, comprising:
- inserting a medical device into a patient through a working channel of an endoscope, the device having a shaft extending distally along the working channel;
- and
- adjusting the device in a telescoping fashion to a desired position that corresponds to an adjustable effective working length of the shaft, such that the shaft extends out of a distal end of the working channel a predetermined distance.
