NCT05142566 | Terminated | Femoral Arteriotomy Closure

MANTA Ultrasound Closure Study
Sponsor:

Essential Medical, Inc.

Brief Summary:

Demonstrate the safety of MANTA Vascular Closure Device (VCD) ultrasound (U/S) guided closure in patients undergoing elective TAVR procedures with planned percutaneous femoral arterial access.

Condition or disease

Femoral Arteriotomy Closure

Intervention/treatment

MANTA Vascular Closure Device

Phase

Not Applicable

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.}}

Criteria
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
