Abstract
Disclosed is a system including a flow control assembly. The system may include a flow regulating shunt system, for various purposes. The flow control assembly may be controlled according to selected parameters and methods.
Claims25
A method of operating a flow and/or pressure regulating assembly for a hydrocephalus shunt system, the method comprising:
- biasing a valve member in a closed position relative to a valve seat with an arm support member;
- sensing a parameter relative to the valve member;
- and
- operating an actuator formed from and on a substrate near the arm support member to be positioned in an active position or an inactive position relative to the arm support member to effect a biasing force applied to the valve member.
A method of operating a flow and/or pressure regulating assembly for a hydrocephalus shunt system, the method comprising:
- providing a reservoir having a reservoir inlet and a reservoir outlet;
- providing a valve member supported relative to a valve seat to regulate flow into the reservoir through the reservoir inlet;
- and
- configuring an actuator in response to an actuator signal from a controller to move the actuator between an activate position and an inactivate position;
- wherein the actuator is selectively positioned in the active position or the inactive position to select a biasing force on the valve member for regulating the flow into the reservoir.
A method of operating a flow and/or pressure regulating assembly for a hydrocephalus shunt system, the method comprising:
- implanting the regulating assembly;
- selecting a set point value for a parameter;
- operating a sensor to cense a parameter value relative to a valve member;
- and
- operating a controller to:
- compare the set point of the parameter to the sensed parameter;
- select a position of the actuator based on the comparison;
- operate the actuator in an active position or an inactive position relative to the valve member to effect a biasing force applied to the valve member.
