Access sheath with integrated closure device

An assembly adapted to access an artery via an access point on a patient's forearm, the assembly comprising:

• a hub including an axially aligned port configured to permit insertion of an elongate member through the axially aligned port;
• an elongate sheath secured to and extending distally from the hub in an engaged configuration;
• a closure device slidingly coupled with the hub and movable between the engaged configuration in which the closure device is coupled with the hub and positioned to secure the hub relative to the patient's forearm at a first position proximal of the access point with the elongate sheath extending distally from the hub and the closure device to the access point;
• and a disengaged configuration in which the closure device has been slid away from the hub and extends about the patient's forearm at a second position distal of the first position, wherein the closure device is configured to be able to extend around the forearm when in the engaged configuration and when in the disengaged configuration;
• and a viewing window disposed within the closure device and positioned to enable viewing of the access point when the closure device, is in the disengaged configuration and disposed over the access point.
