1. A urethral implant delivery device for treating a prostatic urethra, the device comprising:
a handle comprising an actuator and a lever;
an outer sleeve extending distally from the handle and insertable into a urethra, the outer sleeve comprising a hollow distal end configured to hold an implant in a contracted state;
an inner tube radially inward of the outer sleeve, a distal portion of the inner tube comprising:
an implant holder configured to partially move longitudinally relative to the outer sleeve upon a first operation of the actuator to uncover a distal segment of the implant while the outer sleeve covers a proximal segment of the implant, the implant holder configured to fully move longitudinally relative to the outer sleeve upon a second operation of the actuator to uncover the proximal segment of the implant and deploy the implant from the outer sleeve; and
a ring coupled to two steering wires coupled to the lever, the ring operable by manipulation of the two steering wires using the lever to steer the inner tube, the ring being steerable while the outer sleeve covers the proximal segment of the implant, wherein the implant holder is connected to the ring; and
an imaging sheath radially inward of the inner tube, a distal end of the imaging sheath comprising an imaging device configured to allow imaging of at least one of an implant or a urethra, the imaging sheath being movable relative to the inner tube upon operation of the actuator.
