Prostate implant aims to relieve urinary symptoms without daily pills
NCT ID NCT04627701
First seen Sep 22, 2026 · Last updated Sep 22, 2026
Summary
Researchers are testing a device called the Omega System in men aged 50 and older who have urinary symptoms from an enlarged prostate, also known as benign prostatic hyperplasia. The procedure uses heat to make a cut in the prostate tissue around the urethra, then places a permanent Omega-shaped implant that holds the passage open. The trial measures changes in urinary symptoms using a standard questionnaire. The study is small, with 26 participants, and is designed to assess safety and potential benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Omega implant, a permanent device placed in the prostate to widen the urethra
- What this could lead to
- If it works, this could offer men with an enlarged prostate a one-time procedure that eases urinary symptoms without daily medication.
- What could go wrong
- This is a small, early study of 26 men, so safety and benefit are not yet established. Implant procedures carry risks of bleeding, infection, or urinary problems, and the device may not relieve symptoms better than existing options.

Unable to comply with the clinical protocol including all the follow-up requirements. 3. Vulnerable population such as inmates or developmentally delayed individuals. 4. Significant comorbidities which would affect study participation. 5. Diagnosed or suspected prostate cancer. If suspected, prostate cancer must be ruled out. 6. Any medical condition or treatment, which in the opinion of the investigator may interfere with the procedure, such as: * Use of concomitant medications (e.g., anticholinergics, antispasmodics, or antidepressants) affecting bladder function. * Patient with coagulopathy due to medications or congenital condition - inability to stop taking anticoagulants and/or antiplatelets for at least 3 days prior to the procedure or coumadin for at least 5 days prior to the procedure; low dose aspirin therapy not prohibited. * Alpha-blockers within 2 weeks of pre-treatment (baseline) evaluation. * Taking 5-alpha reductase inhibitors (5-ARI) within 6 months (3 months for type II 5-ARI) of pre-treatment (baseline) evaluation unless evidence of same drug dose for at least 6 months with a stable voiding pattern (the drug dose should not be altered or discontinued throughout the study). * Patient is taking steroids. \[Note: Patients approved for the trial who are using the above medications will continue using them after the trial, except for Alpha blockers\] 7. Previous prostate surgery such as: TURP, stent implantations, laser prostatectomy, hyperthermia or another invasive treatment to the prostate. 8. Compromised renal function due to obstructive uropathy. 9. Active Urinary Tract Infection (UTI). 10. Obstructive or protruding median lobe 11. American Society of Anaesthesiologists score (ASA) \> 3. 12. Known neurogenic bladder or neurological disorders that might affect bladder or function. 13. Recent myocardial infarction (less than three months). 14. Concomitant bladder stones. 15. Current gross hematuria. 16. Active or history of epididymitis within the past 3 months. 17. Presence of an artificial urinary sphincter or stent(s) in the urethra or prostate. 18. Confirmed or suspected malignancy of bladder. 19. History or presence of strictures in the anterior urethra or bladder neck contracture or detrusor muscle spasms. 20. Other Urethral conditions that may prevent insertion of Delivery Device into prostatic urethra. 21. Bacterial prostatitis within the last 12 months. 22. Previous rectal surgery, other than hemorrhoidectomy. 23. Current uncontrolled diabetes (i.e., hemoglobin A1c ≥ 9%). 24. Known allergy to nickel or titanium or stainless steel.
