简要总结

The TIVUS II is a prospective, multicenter, non-randomized, open-label clinical study of the safety and performance of the TIVUS™ System consisting of three (3) concurrent cohorts:

  • TIVUS™ Severe Resistant HTN Cohort
  • TIVUS™ Moderate Resistant HTN Cohort
  • TIVUS™ Failed RF Therapy Cohort

入选标准

  • Patient is ≥ 18 and ≤ 80 years of age
  • For Cohort A: Documented office systolic blood pressure > 160 mmHg (> 150 mmHg for diabetic patients); For Cohort B: Documented office systolic blood pressure > 140 mmHg (> 130 mmHg for diabetic patients); For Cohort C: Documented office systolic blood pressure > 150 mmHg (> 140 mmHg for diabetic patients)
  • Documented 24 hour systolic ABPM > 135 mmHg
  • Adherence to a stable drug regimen
  • For patients in Cohort C only: Documented renal denervation procedure with any RF technology 12 months or more prior to screening
  • Suitable renal artery anatomy
  • Male or non-pregnant / non-lactating female
  • Patient understands the nature of the procedure and provides written informed consent
  • Patient is willing and able to comply with the specified study requirements and follow-up evaluations

排除标准

  • eGFR < 45mL/min/1.73m2
  • Documented primary pulmonary hypertension
  • Patient experienced >1 episode of orthostatic hypotension coupled with syncope
  • Documented indicator of a secondary renal hypertension
  • History of myocardial infarction, unstable angina pectoris, or a cerebrovascular accident within 6 months
  • Planned major surgery or cardiovascular intervention in the next 6 months
  • Surgery or cardiovascular intervention in the previous 3 months
  • Hemodynamically significant valvular heart disease
  • Severe debilitating lung disease
  • Patient on anticoagulant therapy that cannot be temporarily withheld for performing catheterization
  • Patient has a single functioning kidney
  • Documented thrombocytopenia, clotting disorders or aortic aneurysms
  • Moribund patient, or patient with comorbidities limiting life expectancy to less than one year
  • Contraindication to recommended study medications or intravascular contrast material that cannot be adequately controlled with pre-medication
  • Concurrent enrollment in another trial
  • Main renal arteries < 4 mm in lumen diameter or < 20 mm in length
  • Aorto-renal angle that prevents a safe cannulation of the renal artery
  • Severe common femoral artery, common and/or external iliac artery, renal, iliac or aortic calcification or tortuosity that may compromise the safe performance and completion of the procedure
  • Hemodynamically or anatomically significant renal artery abnormality or stenosis in either renal artery
  • Any renal artery stenosis > 50% by visual assessment
  • Any renal artery aneurysm in either renal artery
  • A history of prior renal artery balloon angioplasty or stenting (for patients in Cohort A and B only, also a history of prior renal denervation at any time)
