Time to Hemostasis

The elapsed time between MANTA deployment (withdrawal of sheath from artery) and first observed and confirmed arterial hemostasis (no or minimal subcutaneous oozing and the absence of expanding or developing hematoma).

Time frame: Immediately after deployment of MANTA VCD

Population: Time to Hemostasis (TTH) was captured in 491/500 subject; 9 subjects did not have TTH recorded.
