An interventional study of Vivifi's Surgical Procedure in Benign Prostatic Hyperplasia, Varicocele Grade II and Varicocele Grade III, sponsored by Vivifi Medical. Recruiting at 1 site in Panama. Open to male participants aged 40 Years to 75 Years. Per ClinicalTrials.gov, last updated 2025-04-11.

The study objective is to evaluate the safety and feasibility of the Vivifi's Treatment.
The Vivifi's Treatment presents an innovative approach for addressing benign prostatic hyperplasia (BPH) as well as clinical/subclinical varicoceles in men. The scientific rationale for conducting this study is to assess the safety and feasibility of the Vivifi's Treatment (a surgical procedure) as a therapeutic intervention for patients with BPH.
Current BPH treatments fall into two major categories:
Surgical removal/destruction of prostatic tissues:
Minimally-invasive Surgical Therapies (MISTs)
The solutions in the first category rely in removing or destroying prostatic tissue. Though effective at reducing urinary symptoms, this damage to the tissue can cause a number of complications. The "non-surgical" solutions fall into the second category. One of the best-studied of these, Urolift, is an implant-based therapy, using internal sutures that are deployed though the urethra that pull the prostatic tissue away from the urethra lumen, repristinating urethral patency. A significant percentage of cases show recurrence of symptoms due to the fact that the prostate continues to grow. Looking at the currently available treatment options, the longer-lasting surgical procedure (group 1). Group 1 procedures, especially TURP, remain "the gold standard" by which all other BPH treatment options are measured.
The Vivifi's Treatment aims to fill the therapeutic gap between the two-category approaches by offering patients a less invasive surgical approach that (1) fixes the root cause of the problem, guaranteeing long lasting effects and (2) does not cause any damage to the prostatic tissue and urethra, thereby preventing the side effects mentioned above. By replumbing a faulty localized vasculature, the Vivifi's technology leverage years of safety data for anastomotic coupling rings enabling it for vascular surgical approaches. These initial clinical studies will prove that this totally novel treatment approach to BPH is safe.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Subjects undergo Vivifi's surgical procedure for treatment of BPH.
Procedure: Vivifi's Surgical Procedure
Subjects undergo Vivifi's surgical procedure for treatment of BPH. The study procedure will be performed in the operating room, under general anesthesia. Subject will undergo a bilateral anastomosis of the internal spermatic vein to the inferior epigastric vein and ligation of the deferential vein via bilateral inguinal/subinguinal incision. The investigators can use of a coupler with appropriate ring size (to be measured intra-operatively based on vessel size) to perform the vascular anastomosis and standard sutures for ligation. The coupler is an FDA approved commercial device. Alternatively, the anastomosis can also be performed using sutures. Incision closure will proceed per institution standard of care.
PRIMARY SAFETY ENDPOINT
Assess the safety of the Vivifi's Treatment through the rate \& type of the procedure related complications, such as bleeding, infection or other tissue damage.
Time frame: will be assessed up to 12-month post-procedure follow-up.
PRIMARY EFFICACY ENDPOINT
Assess the changes in International Prostate Symptoms Score (IPSS) from baseline to post-procedure. The score range of the questionnaire is 0 to 35. A higher score indicates worse symptomatic.
Time frame: to be assessed at baseline and post-procedure 1 months, 3 months, 6 months and 12 months follow-ups.
SECODARY EFFICACY ENDPOINT 1
Changes in International Index of Erectile Function (IIEF) questionnaire scores. The questionnaire has 15 questions. Each question is scored from 0-5. A higher score indicates improved erectile function.
Time frame: to be assessed at baseline and post-procedure 1 months, 3 months, 6 months and 12 months follow-ups.
SECODARY EFFICACY ENDPOINT 2
Changes in size (volume) of the prostate measured by transrectal ultrasound and cystoscope in mL.
Time frame: to be assessed at baseline and post-procedure 1 months, 3 months, 6 months and 12 months follow-ups.
SECODARY EFFICACY ENDPOINT 3
Change in peak urinary flow (Qmax) in mL/sec.
Time frame: to be assessed at baseline and post-procedure 1 months, 3 months, 6 months and 12 months follow-ups.
SECODARY EFFICACY ENDPOINT 4
Change in post-void residual urine volume in mL.
Time frame: to be assessed at baseline and post-procedure 1 months, 3 months, 6 months and 12 months follow-ups.
Started Nov 2024 (actual). Primary completion is estimated for Apr 2026, 17 months after the start.
Of 51 industry-sponsored interventional studies with no phase under Prostatic Hyperplasia, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 50. This study's planned 17 months is below that.
Counting every sponsor, half of 203 studies reached it within 26 months; a quarter within 14 and three quarters within 48.
