MRI compatible intrabody fluid transfer systems and related devices and methods

摘要

Systems and methods for transferring fluid to or from a subject use a set of MRI compatible components that can aspirate intrabody structure and/or fluids. The components include a device guide, a semi-rigid guide sheath configured to slidably extend through the device guide, a stylet releasable coupled to the guide sheath and extending a fixed distance out of a distal end thereof, and a cannula coupled to flexible tubing that is releasably interchangeably held in the guide sheath in lieu of the stylet.
