Document Type and Number:
WIPO Patent Application WO/2014/043225
Kind Code:
A3
Abstract:
Subject matter relating to pressure regulation is described. In one illustrative embodiment, an apparatus for regulating pressure may include a supply chamber, a control chamber, and a charging chamber. The supply chamber may have a supply port adapted for coupling to a supply lumen, and the control chamber may have a control port adapted for coupling to a feedback lumen. The charging chamber can be fluidly coupled to the supply chamber through a charging port. A regulator valve within the control chamber can operate to control fluid communication through the charging port based on a differential between pressure in the control chamber and a target pressure.
