研究概览
简要总结
The purpose of the study is to evaluate the safety and effectiveness of a minimally invasive surgical procedure in up to 109 male patients. The ProACT device is designed to treat men who have stress urinary incontinence arising from intrinsic sphincter deficiency following an operation performed on the prostate for cancer or for benign prostatic hyperplasia. Two adjustable balloons (one on each side of the urethra) are implanted to treat urinary stress incontinence.
The results will be analyzed to demonstrate the effects of the device as well as its associated risks. Therapeutic success will be based on whether patients demonstrate at least a 50% reduction in pad weight at 18 months follow-up compared to the pad weight results at baseline.
详细描述
The study is a prospective, non-randomized multi-center investigation. Multiple measurements using 24 hour pad weight and pad count, validated questionnaires, voiding diaries will be used to evaluate the achievement of the study objectives. Subjects will be followed for a minimum of 18 months following implantation. Subjects will be requested to continue annual follow-ups through the FDA approval.
