- Candidate for elective or planned (i.e., not emergent or urgent) percutaneous transcatheter treatment procedure through:
- The common femoral artery using 8F to 22F devices or sheaths (max 26F OD; e.g., TAVR, EVAR)
- The common femoral vein using 8F to 26F devices or sheaths (max 30F OD; e.g., transcatheter mitral/tricuspid valve repair/replacement and LAA occlusion)
What rules you out
- Individuals who are pregnant, planning to become pregnant, or lactating
- Immunocompromised or with pre-existing autoimmune disease
- Active systemic infection or a local infection at or near the access site
- Known or suspected COVID-19 infection
- Significant anemia (hemoglobin \<10 g/dL, hematocrit \<30%)
- Morbidly obese or cachectic (Body mass index [BMI] \>40 kg/m2 or \<20 kg/m2)
- Severe co-existing co-morbidities which, in the opinion of the investigator, would clinically confound the study primary endpoints
- Known bleeding disorder including thrombocytopenia (platelet count \<100,000 cells/UL), thrombasthenia, hemophilia, or von Willebrand disease
- Allergy to any device material, including polypropylene, NiTinol, or Titanium
- Common femoral artery or vein with calcium, as determined by baseline CTA or angiogram, which, in the clinical judgment of the investigator, precludes safe access, or severe peripheral vascular disease as evidenced by...
- Previous iliofemoral intervention in the region of the access site, including prior atherectomy, stenting, or surgical or grafting procedures
- Use of an intra-aortic balloon pump through the access site within 30 days prior to the baseline evaluation
- Continuous oral anticoagulation therapy that cannot be stopped for the peri-procedural period or international normalized ratio (INR) \>1.8 at the time of the procedure
- Unable to be adequately anti-coagulated for the procedure
- Unable to ambulate at baseline (e.g., wheelchair user or confined to bed)
- ST-elevation myocardial infarction (MI) within 30 days prior to procedure or acute coronary syndrome (i.e., unstable angina or MI) ≤30 days before the catheterization procedure
- New York Heart Association (NYHA) class IV heart failure
- Left ventricular ejection fraction \<20%
- Unilateral or bilateral lower extremity amputation
- Renal insufficiency (serum creatinine \>2.5 mg/dl) or on dialysis therapy
- Existing nerve damage in the ipsilateral leg
- Additional planned endovascular procedure within the next 30 days
- Currently participating in another clinical trial of an unapproved investigational device or drug that has not concluded the follow-up period
- Vulnerable subject populations (e.g., incarcerated or cognitively challenged adults) Intraprocedural Exclusion Criteria Patients will be excluded from participating in this trial if any of the following exclusion...
- Hypertension with blood pressure (BP) ≥180/110 mm Hg at the initial time of the procedure that cannot adequately be controlled.
- Presence of the following at the target access site (arterial or venous): i) hematoma, ii) AV fistula, iii) pseudoaneurysm, or iv) thrombus
- Puncture site scenarios for the femoral artery or vein:
- Sites in target groin within the prior 14 days
- Sites in the target that have not healed
- Puncture is through the posterior wall or if there are multiple punctures in the same access site
- Access site above the most inferior border of the inferior epigastric artery/vein and/or above the inguinal ligament based upon bony landmarks
- Access site is below the femoral artery/vein bifurcation
