Zusammenfassung:A persistent perfusion sheath assembly can be used for the passage of an intravascular medical device while maintain a flow passage in the vessel. The sheath assembly passes through an arteriotomy and can include a first lumen configured for the passage of a medical device, a second lumen configured to allow a flow of fluid from a location in the blood vessel upstream of the arteriotomy to a location downstream, of the arteriotomy. The sheath assembly can further include a stylet, a sleeve or an additional sheath configured to selectively open and close the flow of blood between upstream and downstream of the arteriotomy. The sheath assembly can further include a closure device distal of the arteriotomy, the closure device configured to control blood flow through the arteriotomy.
