1. A flow isolator adapted for use in controlling a flow of body fluid to a primary body conduit and to a secondary body conduit forming an intersection with the primary body conduit, the isolator including:

  • a sleeve having a flexible wall with a proximal end and a distal end, the sleeve being adapted for operational disposition within the primary conduit and across the intersection with the secondary body conduit, with the distal end of the sleeve being adapted to face in the direction of flow of the body fluid in the primary body conduit;

    first portions of the sleeve at the proximal end of the sleeve being adapted to expand radially outwardly to form a seal with the primary body conduit proximally of the intersection with the secondary body conduit, to facilitate flow inwardly of the sleeve while inhibiting flow outwardly of the sleeve;

    intermediate portions of the sleeve between the proximal end and the distal end directing the flow of body fluid through the sleeve and past the intersection with the second body conduit; and

    second portions of the sleeve at the distal end of the sleeve directing the flow of body fluid from the sleeve into the primary body conduit distally of the intersection with the secondary body conduit.
