Abstract

Systems are provided including a sheath and cannula combination device for permitting a user to select between directing blood flow through a first cannula portion of the combination device in a cannula mode and enabling an interventional medical procedure through a second sheath portion of the combination device in a sheath mode, or performing both the cannula mode and the sheath mode simultaneously. The combination device may include a connector hub configured to auto-washout stasis regions of blood within the first cannula portion. The systems may include a series of removable caps for temporarily sealing the first cannula portion and/or the second sheath portion of the combination device, such that the user may seamlessly select when to use the combination device in the cannula mode, the sheath mode, both the cannula mode and the sheath mode simultaneously, or neither the cannula mode nor the sheath mode.
