Description of intervention(s) / exposure
Other interventions - Manual compression
Treatment: Devices - Cardiva VASCADE™ Vascular Closure System

Active comparator: Manual compression - Using manual compression to reach hemostasis

Experimental: VASCADE™ Vascular Closure System - The Cardiva VASCADETM Vascular Closure System (VCS) is indicated for the percutaneous closure of common femoral artery access sites while reducing times to hemostasis and ambulation in patients who have undergone diagnostic or interventional endovascular catheterization procedures utilizing 6 Fr or 7 Fr procedural sheaths.

6. Currently involved in any other investigational clinical trial;
7. Ipsilateral femoral arteriotomy within the previous 30 days;
8. Planned endovascular procedure within the next 30 days;
9. Previous ipsilateral femoral artery closure using a permanent implant-based closure device;
10. Previous vascular grafts or surgery at the target vessel access site;
11. History of symptomatic peripheral arterial disease, revascularization or deep vein thrombosis in the ipsilateral limb;
12. Unilateral or bilateral lower extremity amputation(s);
13. Significant anemia with a hemoglobin level less than 10 g/dL or a hematocrit less than 30%;
14. Renal insufficiency (serum creatinine of > 2.5 mg/dl);
15. Females who are pregnant, planning to become pregnant within 3 months of the procedure, or lactating;
16. Extreme morbid obesity (BMI greater than 45 kg/m2) or underweight (BMI less than 20 kg/m2);
17. Unable to routinely walk at least 20 feet without assistance (see protocol);
18. Known allergy/adverse reaction to bovine derivatives, sodium hyaluronate or hyaluronan preparations;
19. Procedures that extend hospitalization (e.g., staged endovascular procedure, CABG);
20. Administration of low molecular weight heparin (LMWH) within 8 hours of the procedure.

Intra-op Exclusion Criteria

1. An introducer sheath with an overall length greater than 11 cm, or not 6 Fr or 7 Fr diameter;
2. Femoral artery diameter less than 6 mm at access site;
3. Difficult insertion of procedural sheath or needle stick problems at the onset of the procedure (e.g., multiple stick attempts, "back wall stick", etc.);
4. Angiographic evidence of more than minimal calcium, atherosclerotic disease, or stent within 1 cm of the puncture site;
5. Overlapping Common Femoral Vein and Femoral Artery at access site;
6. Placement of ipsilateral venous sheath during procedure;
7. Arterial access site located not at common femoral artery (e.g., on or below the bifurcation, above the lower border of the inferior epigastric artery, or above the pelvic brim);
8. More than one access site required;
9. Loss of distal pulses in the ipsilateral extremity during the procedure;
10. Subjects receiving unfractionated heparin with an ACT greater than 300 seconds in the absence of a glycoprotein IIb/IIIa inhibitor or greater than 250 seconds in the presence of a glycoprotein IIb/IIIa inhibitor (may wait to remove introducer sheath until ACT level reaches the target value);
11. Intra-procedural bleeding around sheath, or suspected intraluminal thrombus, hematoma, pseudoaneurysm, or AV fistula;
12. Systemic hypertension (BP greater than 180/110 mmHg) or hypotension (BP less than 90/60 mmHg) prior to randomization;
13. Length of the tissue tract, the distance between the anterior arterial wall and skin, is estimated to be less than 2.5 cm;
14. If the physician deems that a different method should be used to achieve hemostasis of the arterial site or that the subject should not attempt ambulation according to the protocol requirements.
