Brief Summary:
The goal of the research study is to observe the clinical safety, effectiveness and patient satisfaction of the AXERA 2 Access System in subjects undergoing coronary angiographic and possible Percutaneous Coronary Intervention (PCI) through the femoral artery when compared to standard manual compression.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Device: Vascular Access Device Procedure: Standard Manual Compression Not Applicable

Detailed Description:

The study is a single center 1:1 randomized controlled trial in subjects undergoing coronary angiography and PCI.

It is anticipated that the enrollment period for this study will be two years.

The post procedure follow up period is up to 37 days following the procedure.

Primary Outcome Measures :
  1. Number of Participants With Any Site-Related Major Adverse Events [ Time Frame: Up to 37 days post procedure ]
    Observation of any major access site related complications (number of participants).

Secondary Outcome Measures :
  1. AXERA 2 Access System Success [ Time Frame: At the time of the femoral artey access procedure up to 1 hour post procedure ]
    Achievement of femoral artery access with AXERA and placement of procedural sheath.

  2. Time to Hemostasis [ Time Frame: From procedural sheath removal until hemostasis is achieved. ]
    Difference between the time the procedural sheath is removed and hemostasis is observed.

  3. Time to Discharge Eligibility [ Time Frame: Up to 1 day post procedure ]
    The time from sheath removal and ambulation to when a subject can be discharged after examination of access site.

  4. Time to Actual Discharge [ Time Frame: Up to 1 day post procedure ]
    Time following procedural sheath removal until actual discharge.

  5. Time to Ambulation [ Time Frame: Up to 1 day post procedure ]
    Time from sheath removal until the participant can stand or walk 20 feet without rebleeding. Ambulation can be evaluated at 1,2, and 4 hours post sheath removal until the participant can ambulate.

  6. Ability to Sit up at 45-degree Angle [ Time Frame: 15 minutes of successful hemostasis ]
    The ability to sit up at a 45-degree angle within 15 minutes of successful hemostasis without rebleed.

  7. Minor Access Site Related Complications [ Time Frame: Up to 37 days post procedure ]
    Observation of any minor access site related complications.

  8. Patient Satisfaction [ Time Frame: Up to 37 days post procedure ]
    Assessed by a patient satisfaction questionnaire.

  9. Pain Score [ Time Frame: Up to 37 days post procedure ]

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject is between 18 and 85 years of age.
  • Cardiac catheterization procedure is indicated with involving access through a 5 French (F) or 6 French (F) introducer in the femoral artery.

  • Subject has an active systemic or cutaneous infection or inflammation (e.g. (septicemia at the time of the procedure).
  • Subject undergoing emergent or urgent cardiac catheterization for acute myocardial infarction.
  • Extensive calcification of the femoral artery as see on fluoroscopy.
  • Subject has systemic hypertension unresponsive to treatment (>180mm Hg systolic and >110mm Hg diastolic).
  • Subject has received thrombolytic therapy within the 72 hours prior to catheterization.
