Primary Outcome Measures:
  • Safety [ Time Frame: 6 month ]
    Incidence of serious adverse events (SAEs) and unanticipated adverse device effects (UADE) reported for the study population from implantation through six (6) months of follow-up.

Secondary Outcome Measures:
  • PERFORMANCE [ Time Frame: 6 Months ]

Estimated Enrollment: 20
Study Start Date: May 2013
Estimated Study Completion Date: June 2020
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MobiusHD™
Device: MobiusHD™
Implant that is placed in the carotid sinus to control hypertension.

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.


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Office cuff SBP ≥ 160 mmHg measured per protocol instructions (Appendix IV) following at least one (1) month of maximally tolerated therapy with at least three (3) anti-hypertensive medications, of which at least one (1) must be a diuretic. Any combination medications will be counted per the active ingredient. (For example, Zestoretic (Lisinopril +HCTZ) equals two (2) anti-hypertensive medications)

Exclusion Criteria:

  • Known or clinically suspected baroreflex failure or autonomic neuropathy
