This is a prospective, two-stage, multi-center, pilot clinical study to evaluate the safety/tolerability/efficacy of the Omega System device. The Omega arc-shaped implant is inserted by the Omega delivery system into the prostate tissue of subjects to relieve lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). The study will first evaluate the Omega system on patients undergoing prostatectomy, which is not indicated for the device.

The ProArc Medical Omega system is a prostatic reshaping device. The Omega System is comprised of two main components: Omega Delivery Device and Omega Implant. The delivery system uses a diathermy electrode to perform a circular and superficial incision through the urethral wall into the prostate tissue, into which the arc-shaped permanent implant is placed. The implant is made up of commonly used surgical implantable nitinol material, coated with Parylene coating. The implant expands the obstructed area, reducing the fluid obstruction through the prostatic urethra.

TERMINATEDPrimary Safety (Stage 1 and Stage 2) - Incidence and severity of procedural and device related adverse events.
Incidence and severity of procedural and device related adverse events.
Time frame: 12 Months
Primary Safety (Stage 2) - Incidence of post-operative catheterization after 7 days, up to 14 days.
Incidence of post-operative catheterization after 7 days, up to 14 days.
Time frame: 2 weeks
Efficacy (Stage 2) - Change in urinary related symptom
Improvement in urinary related symptoms as evidenced by at least 30% decrease in International Prostate Symptom Score (A score of 0-7 indicates mild symptoms, 8-19 indicates moderate symptoms and 20-35 indicates severe symptoms)
Time frame: 3 Months
Functionality (Stage 1) - Location and orientation of Omega implant in the prostate before prostatectomy is as planned: Yes/No
Evaluating whether the outcome of the Omega implant's location and orientation turned out as the surgeon planned prior to the Omega procedure.
Time frame: Procedure day
Functionality (Stage 1) - Location and depth Omega incision in the excised prostate is as planned: Yes/No.
Evaluating whether the Omega incision location and depth outcome turned out as the surgeon planned prior to the Omega procedure.
Time frame: Procedure day
Usability (Stage 1 and Stage 2) - Evaluate the usability of the device and entire process
Evaluate the usability of the device and the entire process using the usability questionnaire (The highest score of 60 indicates that the device is extremely user-friendly, while the lowest score of 12 indicates that the device is very difficult to use)
Time frame: Procedure day
Efficacy (Stage 2) - Improvement in urinary related symptoms
Evaluate the improvement in urinary-related symptoms as evidenced by a decrease of at least 30% in the IPSS score. (A score of 0-7 indicates mild symptoms, 8-19 indicates moderate symptoms and 20-35 indicates severe symptoms)
Time frame: 1 Months, 6 Months and 12 months
Efficacy (Stage 2) - Improvement of peak urinary flow rate as evidenced by an increase of at least 25% in uroflowmetry Qmax
Time frame: 1 Months, 3 Months, 6 Months and 12 months
Exploratory - Change in PSA compared to baseline
Time frame: 1 Months, 6 Months and 12 Months
Exploratory - Change in sexual function assessments from screening to 3, 6 and 12 months using the International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire for Ejaculatory Function (MSHQ-EjD).
The IIEF-15 score ranges from 6 to 75 and is used to classify erectile dysfunction (ED). An MSHQ-EjD score of 20 indicates the absence of ejaculatory dysfunction, while a score of 0 indicates a high level of ejaculatory dysfunction.
Time frame: 3 Months, 6 Months and 12 months
Exploratory - Change in VAS pain score
A VAS pain score of (0-1 mm) indicates no pain,(2-4 mm) - mild pain, (4-7 mm) - moderate pain, and (7-10 mm) - severe pain.
Time frame: Procedure day, 1-2 weeks and 1 month
Exploratory - Change in post-void residual (PVR) test
Time frame: 1 Months, 3 Months, 6 Months and 12 months
Exploratory - Incidence of inflammation, assessed by cystoscope
Time frame: 6 months
Exploratory - Omega coverage assessed by cystoscope
Time frame: 6 months
Exploratory - Change in the BPHII score from Baseline
Time frame: 1 Months, 3 Months, 6 Months and 12 months
Incidence of repeat invasive treatment for Lower Urinary Tract Symptoms (LUTS) or increase in dosage or initiation of new medication to treat symptoms of BPH
Time frame: 12 months
Incidence of Device removal
Time frame: 12 months
