Abstract: Disclosed are apparatuses and methods for irradiating a perfusate. The apparatus includes a tank which defines a first chamber. A separator is located inside the first chamber. The separator defines a second chamber. The first chamber and the second chamber are concentric and have substantially annular cross sections, each having at least one diameter and a substantially common longitudinal axis. A perfusate is introduced into the first chamber by an inlet. A UV radiation-emitting device is disposed inside the second chamber for providing irradiation to the perfusate. Irradiated perfusate is removed from the tank by an outlet. Other apparatuses and systems are described and methods for inactivating micro organisms by performing EVP and irradiating the perfusate.

Abstract: 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.
