1. A shunt, comprising:
- a conduit sized to fit within Schlemm'"'"'s canal, the conduit having a proximal end, a distal end, and an inlet intermediate the proximal end and the distal end; and
a Venturi feature configured and arranged within the conduit so as to be capable of controlling flow from the inlet into the conduit.

Abstract
A shunt having a conduit sized to fit within Schlemm'"'"'s canal, the conduit having an inlet intermediate a proximal end and a distal end and a Venturi feature arranged within the conduit so as to control flow from the inlet into the conduit. The shunt may include a pressure sensor capable of measuring pressure within an eye, coupled to the Venturi feature, the Venturi feature being configured to control flow from the inlet into the conduit in response to a pressure measurement from the sensor. Also, the pressure sensor may be coupled to a pump that is adapted to control flow from the inlet into the conduit in response to a pressure measurement from the sensor.

23. A method of controlling a pressure in an anterior chamber of an eye, comprising:
-
providing in a Schlemm'"'"'s canal of the eye a conduit having a Venturi feature disposed therein; and
controlling flow along the Venturi feature, thereby achieving a pressure proximate an inlet from the anterior chamber into the Schlemm'"'"'s canal. - View Dependent Claims (24, 25)
