1-52. (canceled)
An endoscopic device comprising:
- a shaft comprising a proximal section and a distal section, the distal section comprising:
- a lumen that extends to a distal opening;
- a torque transfer mechanism that includes a torque transfer element;
- and
- a cavity extending distal to the opening;
- and
- a rotatable coupling between the proximal section and the distal section;
- wherein the cavity receives the torque transfer element, and rotation of the torque transfer element drives rotation of the distal section relative to the proximal section.
An endoscopic device comprising:
- a shaft comprising a proximal section and a distal section, the distal section comprising:
- a lumen extending through the proximal section and the distal section, the lumen terminating at a distal opening;
- and
- a torque transfer element;
- and
- a rotatable coupling between the proximal section and the distal section;
- wherein the torque transfer element extends distal to the rotatable coupling and is configured to drive rotation of the distal section relative to the proximal section.
