Brief Summary:
The study described below is designed to assess the safety and device performance for the drug coated balloon (DCB) for the treatment of urethral stricture.

Condition or disease Intervention/treatment Phase
Urethral Stricture Device: Urotronic Drug Coated Balloon (DCB) Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Device Feasibility
Official Title: Re-establishing Flow Via Drug Coated Balloon For The Treatment Of Urethral Stricture Disease
Actual Study Start Date : October 25, 2017
Estimated Primary Completion Date : October 2018
Estimated Study Completion Date : December 2022

Arm Intervention/treatment
Experimental: Treatment
Up to 15 subjects will be enrolled and treated with the Urotronic drug coated balloon (DCB)
Device: Urotronic Drug Coated Balloon (DCB)
The Urotronic Drug Coated Balloon (DCB) is a guidewire compatible catheter with a tapered atraumatic tip. The distal end of the catheter has an inflatable balloon coated with a proprietary coating containing the drug paclitaxel that facilitates the drug's transfer to the urethral wall upon inflation.




Primary Outcome Measures :
  1. Safety- Rate of Device Related Serious Complications [ Time Frame: 90 days ]

Secondary Outcome Measures :
  1. Safety- Change in IIEF (International Index of Erectile Function) [ Time Frame: 90 days ]
  2. Efficacy- Stricture Recurrence Rate [ Time Frame: 6 months ]
