US 12,109,379 B2 · System and method for draining cerebrospinal fluid in hydrocephalus patients

Abstract

A system and related method are provided for draining cerebrospinal fluid from a bodily cavity of a patient, such as a ventricle in the brain in one application. The system includes a reservoir which may be a collapsible container configured for fluidic connection to a shunt located in the bodily cavity. The collapsible container may be an elastically deformable bladder in one embodiment. A pump is fluidly connected to the collapsible container and draws cerebrospinal fluid therefrom. A programmable controller directs the pump to repeatedly activate and deactivate at a predetermined time interval. A plurality of sensors may be provided which are communicably coupled to the controller for monitoring pump motor current draw, tension in the resilient body of the container, pressure, and orientation of the patient. The controller is configurable to deactivate the pump when abnormal operating conditions are detected by the sensors.

Dependent claims

A system for draining cerebrospinal fluid from a bodily cavity of a patient, the system comprising:

a collapsible container configured to be fluidly connected to a shunt that is located in the bodily cavity containing the cerebrospinal fluid;
a drain line fluidly coupling the shunt directly to the collapsible container, the drain line forming a single inlet into the collapsible container;
a pump fluidly connected to the collapsible container;
and
a programmable controller that directs the pump to repeatedly activate and deactivate to draw cerebrospinal fluid from the collapsible container;
the collapsible container being located in the patient such that there is no contact between the collapsible container and bodily cavity;
wherein the collapsible container is interposed between the drain line and the pump;
wherein a blockage in the drain line or shunt upstream of the collapsible container when the pump is operating causes the collapsible container to collapse and fluidly isolate the pump from the bodily cavity to prevent subjecting tissue surrounding the bodily cavity to negative pressure generated by the pump.
