1. A device, comprising:
an optical fiber configured to pass laser energy therethrough, the optical fiber having an emitting location configured to transmit laser energy into a fluid causing a cavitation bubble to propagate a pressure wave;
an elongated body having a proximal portion and a distal portion opposite the proximal portion, the elongated body extending along a central longitudinal axis, the optical fiber extending at least partially along the elongated body and spaced from the central longitudinal axis; and
a controller configured to translate the optical fiber longitudinally independently from the elongated body, the optical fiber extending at least partially through the controller and therefrom towards the elongated body, the controller comprising:
a lower telescope fixedly coupled to at least a portion of the optical fiber;
an upper telescope telescopically coupled to the lower telescope, such that the lower telescope is configured to translate longitudinally within and from the upper telescope;
a longitudinal actuator configured to translate the lower telescope with respect to the upper telescope, thereby translating the optical fiber longitudinally;
a proximal stopping feature associated with a proximal treatment location;
a distal stopping feature associated with a distal treatment location; and
at least one stopping feature located between the proximal stopping feature and the distal stopping feature,
wherein the proximal stopping feature, the distal stopping feature, and the at least one stopping feature are configured to i) prevent longitudinal movement of the lower telescope in at least one direction, ii) provide a resistance for longitudinal movement of the lower telescope in at least one direction, or iii) both, and
wherein the stopping features are located along the path on which the longitudinal actuator moves.
