Study summary

To evaluate the safety and performance of the MobiusHD system in subjects with resistant hypertension.

Read the detailed description

This is an open-label, multicenter, first-in-man clinical trial to be conducted inside the United States. Eligible subjects with stage 2 resistant systemic arterial hypertension currently being treated with a minimum of three (3) anti-hypertensive drugs, who consent to study participation will be assigned to treatment with the MobiusHD system.

Potential study participants will be consented and then screened at two (2) baseline visits beginning at least 30 days prior to MobiusHD placement. Qualified patients will undergo placement of the MobiusHD under angiographic visualization, and will then be followed for 36 months.
