1. An apparatus comprising:
an elongate tubular structure having a first end and a second end;
a therapeutic device interface located at the first end of the elongate tubular structure
a magnet positioned within the therapeutic device interface;
an actuation mechanism connected with the second end of the elongate tubular structure, the actuation mechanism having a first portion that is fixed in space relative to the second end of the elongate tubular structure and a second portion that is movable relative to the second end of the elongate tubular structure; and
an actuation member disposed within the elongate tubular structure, wherein:
the actuation member connects the magnet to the second portion of the actuation mechanism,
the actuation mechanism is configured to cause the second portion to be movable, responsive to one or more inputs, between at least a first predetermined location relative to the first portion, a second predetermined location relative to the first portion, and a third predetermined location relative to the first portion,
the second predetermined location relative to the first portion is in between the first predetermined location relative to the first portion and the third predetermined location relative to the first portion, and
the actuation member causes the magnet to move relative to the therapeutic device interface responsive to movement of the second portion of the actuation mechanism relative to the first portion of the actuation mechanism.
