1. A system for engaging and manipulating a median lobe of a prostate gland, comprising:
A delivery device comprising an elongate tissue access assembly, wherein the elongate tissue access assembly is configured to be inserted within an introducer sheath; and
a tissue engagement structure configured to engage and manipulate a median lobe of a prostate gland, wherein the tissue engagement structure is attached to a distal end portion of the elongate tissue access assembly, wherein the tissue engagement structure includes a distal end portion with an expandable member secured to the distal end portion of the elongate tissue access assembly, wherein the expandable member comprises curved portions having connected distal ends such that the tissue engagement structure can transition from a contracted state, in which the curved portions are compressed toward a midline defined by a longitudinal axis of the tissue engagement structure, to an expanded state, in which the curved portions expand outward from the midline defined by the longitudinal axis of the tissue engagement structure.
