Claims21
1-25. (canceled)
A medical instrument assembly comprising:
- a shaft including:
- a distal end region having a port,
- a working channel in communication with the port, and
- an elevator positioned at the port;
- and
- a medical device configured for positioning in the working channel, and capable of extending distally from the port, the medical device including:
- at least one first protrusion projecting outwardly from a surface of the medical device, the first protrusion extending circumferentially along the surface, and
- a second protrusion projecting outwardly from the surface, the second protrusion extending longitudinally along the surface.

A medical instrument assembly comprising:
- a shaft including:
- a distal end region having a port,
- a working channel in communication with the port, and
- an elevator positioned at the port, the elevator including a notch;
- and
- a medical device configured for positioning in the working channel, and capable of extending distally from the port, the medical device including:
- at least one first protrusion on a first side of the medical device, and
- a second protrusion on a second side of the medical device, the second protrusion extending at an angle relative to the first protrusion,
- wherein the medical device is configured to move relative to the elevator between a first configuration, with the notch engaging a surface of the medical device beside the first protrusion, and a second configuration, with the notch engaging the second protrusion.

An endoscopic instrument assembly comprising:
- an endoscope including a shaft, the shaft having:
- a distal end region with a port,
- a working channel in communication with the port, and
- an elevator positioned at the port, the elevator including a notch;
- and
- a catheter configured for introduction into the working channel and extension distally from the port, the catheter including:
- at least one first protrusion on a first side of the catheter, and
- a second protrusion on a second side of the catheter, the second protrusion intersecting the first protrusion,
- wherein the catheter is configured to move relative to the elevator between a first configuration, with the notch engaging a surface of the catheter beside the first protrusion, and a second configuration, with the notch engaging the second protrusion.
