Apparatuses and methods for accessing and disrupting a tissue are disclosed herein. In one embodiment, a method includes inserting a distal end portion of an elongate member into a biological body. After inserting the elongate member, an actuator is manually actuated to produce translational motion of a drive element. The translational motion is converted into rotational movement of the distal end portion of the elongate member. In one embodiment, an apparatus includes an elongate member having a tissue interaction member at a distal end portion that is configured to be inserted within a biological body. A conversion mechanism is coupled to the elongate member and includes a drive element. An actuator is coupled to the conversion mechanism and is configured to cause translational motion of the drive element. The conversion mechanism is configured to convert the translational motion of the drive element into rotational motion of the elongate member.
