Abstract: Se enseña una cánula para conectar un dispositivo médico a un sistema biológico. La cánula incluye una porción de acoplamiento de tejido, preferiblemente en forma de anillo, a la que se aplica un vacío a través de la cánula para atraer y mantener el tejido del sistema biológico en una conexión inicial mientras se aplica un dispositivo de fijación para completar la conexión. Además de un conducto de fluido de trabajo, que comprende un puerto principal, un paso de fluido de trabajo y un puerto de fluido de trabajo, y un puerto para aplicar el vacío, la cánula puede incluir un puerto de sensor para permitir detectar la presión u otras características del fluido de trabajo en un punto muy adyacente a la conexión entre la cánula y el sistema biológico.

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.
