Angio-Seal device deployed over the guide wire into the subclavian artery. Angiographic runs obtained from the catheter placed via the axillary artery showed no extravasation of contrast from the subclavian artery at the site of the Angio-Seal deployment (Figures 3 and 4), confirming procedural success.
