Benign Prostate Hyperplasia
Conditions
Brief summary
The study objectives are to demonstrate the efficacy and safety of the Medi-Tate iTIND as compared to control group (catheter only).
Detailed description
Medi-Tate i-Temporary Implantable Nitinol Device (iTind) is intended to treat subjects with symptomatic BPH. A total of 150 subjects with symptomatic BPH will be enrolled into this study, according to eligibility criteria. Study duration is 12 months and includes 7 visits: screening, screening follow up, implantation, retrieval, 6 weeks follow up, 3 months follow up and 12 months follow up. iTind Device will be implanted for 5-7 days. Sham will be a routine Foley catheter procedure.

Participant flow
Recruitment details
Sixteen centers participated in the study (14 in the United States, 2 in Canada) between July 2015 and October 2018. First patient was recruited on July 2015.
Pre-assignment details
All patients on BPH related medications started a wash-out period prior to implantation: 1 month for alpha-blockers and 6 months for 5-alpha-reductase inhibitors (5-ARIs). Medication naïve patients seeking treatment refused medication in preference for a minimally invasive surgical technique.
