Abstract
A cannula for an ECLS system may include a tubular member and an actuatable structure. The actuatable structure may be responsive to an external stimulus such that an inner diameter of the tubular member changes as the external stimulus changes. A system may include the cannula and a controller in electrical communication with the actuatable structure. The controller may be user-configurable to set a desired value for an inner diameter of the tubular member. A method of connecting a patient's vasculature to an ECLS system may include advancing a delivery sheath into the vasculature, moving the delivery sheath relative to the cannula to expose the cannula within the vasculature, and shifting the actuatable structure from a first configuration to a second configuration while at least a portion of the cannula is disposed within the vasculature to change an inner diameter of the tubular member.
