A Patient Registry Evaluating Closure Following Access With the ArstasisOne Access System

Inclusion Criteria: * Patient is between 18 and 85 years of age. * Patient is clinically indicated for a diagnostic catheterization procedure involving access through a 5F or 6F introducer in the femoral artery. * Patient is able to ambulate without assistance prior to the procedure and can be expected to ambulate (20 feet) post-procedure. Exclusion Criteria: * Patient is unable to routinely walk at least 20 feet without assistance (e.g., requires a walker or wheelchair to mobilize or has known paralysis). * Patient has an active systemic or cutaneous infection or inflammation (e.g., septicemia at the time of the procedure). * Patient has systemic hypertension unresponsive to treatment (\>180mmHg systolic and \>110mmHg diastolic). * Patient has received thrombolytic therapy within the 72 hours prior to catheterization. * Patient has a previously diagnosed significant bleeding coagulopathy, is on warfarin and has an INR ≥ 1.5 or has a platelet disorder, including known thrombocytopenia (platelet count \<100,000), thrombasthenia, Von Willebrand's disease, Factor V deficiency, or anemia (Hemoglobin\< 10 g/dL, or Hct\<30%). * Patient has a compromised femoral artery access site. * Patient procedure requires an introducer sheath size of\> 6F. * Patient has had prior vascular surgery or vascular grafts at the femoral artery access site. * Patient presents with hemodynamic instability or is in need of emergent surgery. * Patient has received femoral artery closure on the target access vessel with a collagen/PEG closure device within 90 days of the current procedure. * Patient has a pre-existing severe non-cardiac systemic disease or illness that results in an expected life expectancy of\< 30 dys or for other reasons has a life expectancy of less than 1 yaer. * Patient is currently participating in an investigational drug or another device study that clinically interferes with the current study endpoints. * Pregnant or lactating patients.
