Apparatuses and methods for accessing and disrupting a tissue are disclosed herein. In one embodiment, an apparatus includes a first elongate member having a tissue interaction portion disposed at a distal end of the first elongate member. The tissue interaction portion is configured to be inserted within a biological body. A second elongate member is movably disposed within a lumen defined by the first elongate member. The second elongate member has a threaded exterior surface. A drive motor is coupled to the first elongate member and coupled to the second elongate member. The drive motor is configured to rotate the first elongate member in a first direction and configured to rotate the second elongate member in a second direction opposite the first direction. The tissue interaction portion is configured to disrupt tissue when disposed into the biological body and when the first elongate member is rotated.
