Abstract
An apparatus for shunting blood includes a flow-indication chamber shaped to define an entry port and an exit port, and one or more moveable objects disposed within the flow-indication chamber and configured to move in response to a flowing of the blood from the entry port to the exit port. At least a portion of a wall of the flow-indication chamber is transparent so as to expose the moveable objects to sight. Other embodiments are also described.
Claims19
Apparatus for shunting blood, the apparatus comprising:
- a flow-indication chamber shaped to define an entry port and an exit port;
- and
- one or more beads, at least one of which comprises multiple faces, disposed within the flow-indication chamber and configured to move in response to a flowing of the blood from the entry port to the exit port,
- at least a portion of a wall of the flow-indication chamber being transparent so as to expose the one or more beads to sight.

A method, comprising:
- coupling an upstream end of a first conduit to a source blood vessel of a subject and a downstream end of the first conduit to an entry port of a shunt;
- and
- coupling an upstream end of a second conduit to an exit port of the shunt and a downstream end of the second conduit to a sink blood vessel of the subject, such that blood flows from the source blood vessel to the sink blood vessel via the shunt, thus causing movement of one or more beads, at least one of which comprises multiple faces, disposed within the shunt, the movement being visible through a wall of the shunt.
Apparatus for shunting blood, the apparatus comprising:
- a flow-indication chamber shaped to define an entry port and an exit port;
- and
- a plurality of beads disposed within the flow-indication chamber and configured to move in response to a flowing of the blood from the entry port to the exit port,
- at least a portion of a wall of the flow-indication chamber being transparent so as to expose the beads to sight,
- wherein, for each bead of the beads, a Cartesian distance between any two points on an outer surface of the bead is less than 0.65 cm.
