Inclusion Criteria

  • Candidate for elective or planned (i.e., not emergent or urgent) percutaneous transcatheter valve replacement (TAVR) via a 10-20F device or sheath (12-25F OD) with common femoral artery approach - Vessel size would allow for access for the MANTA VCD based on vessel size as determined by baseline CTA: minimum vessel diameter of 5mm for the 14F MANTA VCD and 6mm for the 18F MANTA VCD - Understand and sign the study specific written informed consent form and PHI authorization - Able and willing to fulfill the follow-up requirements

Exclusion Criteria

  • Patients known to be pregnant or lactating - Patients who have a systemic infection or a local infection at or near the access site - Patients with significant anemia (hemoglobin ≤10 g/DL) - Patients who are morbidly obese or cachectic (BMI >40 or <20kg/m2) - Patients with a known bleeding disorder including thrombocytopenia (platelet count <100,000 cells/UL), thrombasthenia, hemophilia, or von Willebrand disease - Patients with allergy to bovine materials or any other device material, including collagen and/or collagen products, polyglycolic or polylactic acid, stainless steel or nickel - Patients with a femoral artery puncture in target groin within the prior 30 days, prior vascular closure device placement in the target common femoral artery within 3 months, or any prior target femoral artery access-related complication - Patients who have undergone use of an intra-aortic balloon pump (IABP) through the arterial access site within 30 days prior to the baseline evaluation. - Patients who have a Common Femoral Artery (CFA) with visible calcium and/or tortuosity, as determined by baseline CTA, precluding safe access and likely to interact with large bore access site arteriotomy, determined by investigator. - Patients with previous iliofemoral intervention in region of access site, including but not limited to prior atherectomy, stenting, surgical or grafting procedures in the access area - Patients in whom oral anticoagulation therapy cannot be stopped for the peri procedural period or patients with INR >1.8 at the time of the procedure - Patients who are unable to ambulate at least 6 meters without assistance at baseline - Patients with renal insufficiency (serum creatinine >2.5 mg/dl) or on dialysis therapy - Patients with existing nerve damage in the ipsilateral leg - Patients with a further planned endovascular procedure within the next 30 days - Patients who have already participated in this IDE study - Patients who are currently participating in another clinical study of an unapproved investigational device or drug that has not concluded the follow-up period or patient currently participating in another clinical study likely to influence hemostasis and vascular complications - Patients who cannot adhere to or complete the investigational protocol for any reason including but not limited to geographical residence, psychiatric condition or life threatening disease - Patients who have a common femoral artery <5mm in diameter for the 14F MANTA VCD or <6 mm in diameter for the 18F MANTA VCD, common femoral artery stenosis resulting in a vessel diameter <5mm in diameter for the 14F MANTA VCD or <6 mm in diameter for the 18F MANTA VCD, or > 50% diameter femoral or iliac artery stenosis - Patients in whom, during initial access of the artery, arteriotomy and surrounding anatomy cannot be visualized and identified clearly under U/S imaging and/or if the vertical depth from the surface of the skin to target area of the common femoral artery measures greater than 6cm

Detailed Description

The MANTA Vascular Closure Device is indicated for closure of femoral arterial access sites while reducing time to hemostasis following the use of 10-20F devices or sheaths (12-25F OD) in endovascular catheterization procedures. This study is being conducted to demonstrate the safety of U/S guided closure with MANTA VCD following TAVR procedures utilizing large bore sheaths.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
