Systems and methods for implants and deployment devices

A method of delivering an expandable implant within a patient's urethra, the method comprising:

• advancing within the urethra a distal end of a sheath housing the implant in a biased, delivery configuration, an elongate grasper slidable within the sheath and releasably coupled with a proximal portion of the implant during the advancing,
• causing relative motion between the elongate grasper and the sheath to expose a distal portion of the implant from within the sheath such that the exposed distal portion of the implant transitions towards its default, deployed configuration, and into engagement with a wall of the urethra to maintain the urethra in an at least partially open state;
• with the exposed distal portion of the implant maintaining the urethra in the at least partially open state and the proximal portion of the implant still housed within the sheath and releasably coupled with the elongate grasper, causing further relative motion between the elongate grasper and the sheath to expose the proximal portion of the implant from the sheath and release the implant from the elongate grasper;
• and
• with the implant released from the elongate grasper, withdrawing the sheath and the elongate grasper from the urethra, leaving the implant in its default, deployed configuration, and in engagement with the wall of the urethra to maintain the urethra in the at least partially open state.
