Systems, devices, and methods for the accurate deployment and imaging of an implant in the prostatic urethra

A method of delivering an implant, the method comprising:

• advancing a delivery device within a urethra of a patient, wherein the delivery device includes an outer tubular member coupled with an imager, an inner tubular member being disposed within the outer tubular member and housing an implant;
• a distal control member slidably advanceable within the inner tubular member to cause deployment of the implant from within the inner tubular member;
• and a proximal control member (1) coupled with the inner tubular member and the distal control member, and (2) releasably coupled with the outer tubular member through a coupling member, wherein the proximal control member is configured to longitudinally move the inner tubular member and the outer tubular member concurrently when the coupling member is in a first position, and longitudinally move the outer tubular member relative to the inner tubular member to adjust the relative spacing between the imager and a distal end of the inner tubular member when the coupling member is in a second position, wherein the proximal control member includes a handle portion that is movable with respect to a proximal handle portion and an anti-rotator that when engaged limits relative rotation between the outer tubular member and the inner tubular member, and wherein the anti-rotator includes a groove on the handle portion that is configured to receive a detent coupled to an inside surface of the proximal handle portion;
• longitudinally retracting the inner tubular member with respect to the proximal control member and the distal control member to at least partially deploy the implant from the inner tubular member;
• and
• releasing the implant from the delivery device.
