  • Cannula for connecting medical devices to biological systems
    Patent number: 11045633
    Abstract: A cannula for connecting a medical device to a biological system is taught.

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.
