Post hoc closure of large bore vascular access using the MANTA closure device.

Successful closure of large bore vascular access (≥12 Fr) is facilitated by the MANTA vascular closure device; however, it requires a critical first step of measuring "skin to arterial wall" depth of the access site using the depth locator before dilating the vessel above 8 Fr. It may be challenging at times to acquire the deployment depth at the onset of the procedure due to case urgency, delayed closure, or when large bore access is obtained at a different institution. We discuss a novel technique of measuring the deployment depth and successful delayed closure of large bore arterial access using the MANTA closure device.
