Pivotal Study of eCoin for Overactive Bladder With Urgency Urinary Incontinence
Study Details
Study Description
Brief Summary
This trial is a prospective, multicenter, single-arm study of the safety and effectiveness of eCoinTM tibial nerve stimulation in subjects having overactive bladder (OAB) with urgency urinary incontinence (UUI). The study will evaluate changes from baseline in OAB symptoms as measured by voiding diaries and patient reported-outcomes through 48 weeks of eCoinTM therapy or 52 weeks of implantation.

Adverse Events

---|---|---|
Adverse Event Reporting Description | The analysis set is comprised of "treatment emergent" adverse events, defined as adverse events occurring on or after implantation or attempted implantation of eCoin. Importantly, all attempted implantations were successful; thus, the safety results are summarized for all implanted patients. At each follow-up visit, patients were asked to report any adverse events and it was recorded on the CRF. | |
