1. A method of using a sheath system configured to receive an interventional tool, the method comprising:
connecting a sheath tube portion to a shunt member portion, the sheath tube portion including:
a proximal end, and
a tube wall configured to bend between a curved configuration and a straight configuration
positioning an interventional tool into the proximal end of the sheath tube portion;
retaining the sheath tube portion in the curved configuration relative to an anatomical vessel by a stabilization device while positioning the interventional tool;
moving the interventional tool within an internal access path defined through the sheath tube portion, the shunt member portion, and the anatomical vessel while the sheath tube portion is connected to the shunt member portion and the sheath tube portion resides entirely external to a patient and the shunt member portion resides partially internal to the patient and partially external to the patient.
