Patent ID: 8911396

Claim:
A method of using a sheath device, the method comprising: positioning a detachable shunt member through a perforation in a side wall of an anatomical vessel, the detachable shunt member including: a distal opening configured to reside in the anatomical vessel, and a connection member that resides external to the anatomical vessel and that includes a first septum configured to receive an interventional tool therethrough; mating a detachable curvable sheath tube to the connection member including the first septum of the shunt member, wherein the detachable curvable sheath tube includes: a distal end that is smaller in outer diameter than, and detachably mated with, a proximal end of the connection member of the shunt member such that the distal opening of the shunt member remains distal of the distal end of the detachable curvable sheath tube; and a proximal end opposite from the distal end, and a tube wall configured to bend between a curved configuration and a substantially straight configuration, wherein the proximal end of the detachable curvable sheath tube is coupled with a septum hub configured to receive the interventional tool, the septum hub having an introducer portion at a proximal end of the septum hub and a secondary tube for injecting or suctioning fluids; moving the interventional tool within an internal access path through the septum hub, the detachable curvable sheath tube, the shunt member, and the anatomical vessel while the distal end of the detachable curvable sheath tube remains fixed relative to the proximal end of the connection member.
