Abstract:
A protective sheath assembly is provided that combines the functions of an introducer, a protective sheath and a sealing valve in an integrated assembly. The protective sheath assembly generally comprises a protective sheath with a connecting member or a hub. The protective sheath has a proximal end, a distal end, and an elongated hollow body defining a lumen along the longitudinal axis. The protective sheath accommodates and protects a medical device during insertion through a hemostasis valve into a patient's vasculature. The protective sheath also provides a seal around the medical device to prevent blood back flow.
