Prospective, multi-center, multinational, 2:1 randomized, single-blinded, controlled clinical trial of the Zenflow Spring System.~Patients randomized to the treatment group will undergo Zenflow Spring placement.~Patients randomized to the control group will undergo a Sham procedure. Patients and site personnel administering follow-up assessments will be blinded to the randomized treatment through completion of the 3-month follow-up visit. Once a patient has completed their 3-month follow-up assessments, they will be unblinded. Following unblinding, patients who received a Sham procedure may elect to receive treatment with the Zenflow Spring System or alternatively they may exit the study.~The duration of study participation is 60 months for patients who receive a Spring Implant and 3 months for subjects in the Control Arm.
Evaluate the safety and effectiveness of the Zenflow Spring System in relieving LUTS associated with BPH.
