1. A system configured to receive an interventional tool, the system comprising:
- a shunt member portion positionable through a perforation in a side wall of an anatomical vessel of a patient, the shunt member portion including;
a distal opening configured to reside in the anatomical vessel, anda member that resides external to the anatomical vessel and external to the patient;
a sheath tube portion mated to the external member of the shunt member portion, the sheath tube portion including;
a proximal end opposite from the shunt member portion, anda tube wall retainable in a curved configuration in which a proximal portion of the sheath tube portion is transverse to the shunt member portion, the proximal end of the sheath tube portion configured to receive the interventional tool; and
a location of increased thickness that prevents migration of the sheath tube portion into the patient, the location of increased thickness located between a portion of the shunt member portion residing internal to the patient and the sheath tube portion;
wherein an internal access path defined through the sheath tube portion, the shunt member portion, and the anatomical vessel is configured to movably receive an interventional tool while the sheath tube portion resides entirely external to the patient and the shunt member portion resides partially internal to the patient and partially external to the patient; and
a clasp device configured to retain the sheath tube portion in the curved configuration.

Abstract
The present application includes a sheath that is suitable for use in a variety of medical procedures. In one or more implementations, the sheath includes a shunt member, and a curvable portion. The curvable portion may be configured in various orientations to facilitate an intervention, such as a hemodialysis intervention, or the like, by an operator. The curvable portion may be configured to bend between a substantially straight configuration and a curved configuration. In implementations, the sheath may be configured to have detachable and/or interchangeable components (e.g., shunt member, curvable portion, etc.).
