A cannula for connecting a medical device to a biological system is taught. The cannula includes a tissue engagement portion, preferably in the form of an annulus, to which a vacuum is applied through the cannula to attract and hold tissue of the biological system in an initial connection while an affixment device is applied to complete the connection. In addition to a working fluid conduit, comprising a main port, a working fluid passage and a working fluid port, and a port to apply the vacuum, the cannula can include a sensor port to allow sensing pressure or other characteristics of the working fluid at a point closely adjacent to the connection between the cannula and the biological system.

An organ perfusion device includes an inlet for connection to the organ, and an outlet for connection to the organ. The device also includes a perfusion circuit including: a reservoir configured to hold a perfusion fluid; a waste receptacle, and a plurality of fluid conduits. The fluid conduits define: a delivery fluid path connecting the reservoir with the inlet; a return fluid path, independent of the delivery fluid path, connecting the reservoir with the outlet; and a waste fluid path connecting the reservoir with the waste receptacle. The device also includes a first flow control device configured to selectively prevent or allow fluid flow from the reservoir to the organ via the delivery fluid path; and a second flow control device configured to selectively prevent or allow fluid flow from the reservoir to the waste receptacle via the waste fluid path.
