Research study which tests the safety and effectiveness of a new vascular closure device to
close the femoral access puncture that is created in patients who require this form of access
in order to perform the planned procedure. The MANTA device is expected to seal the femoral
access puncture in less than 1 minute. This may result in less blood loss and a shorter time
to walking compared to alternative closure means. Use of the MANTA device in this study is
experimental. All other parts of the procedure involve standard medical care.
