The Angioseal closure device is a vascular plug that has been approved by the FDA in order to seal the femoral artery arteriotomy and allow for a faster ambulation time after cardiac catheterization. Currently, the Angioseal device has been approved for ambulation times of 20 minutes after diagnostic left heart catheterization but a more conservative approach is typically used after device. A very common strategy after Angioseal is to keep the patient flat for 2 hours prior to ambulation and then to keep the patient another hour after ambulation for observation of the femoral site.
