Abstract
An implantable medical device is configured with a pressure sensor arranged within the device to reliably and accurately measure the pressure within a propellant gas chamber at least partially surrounding a therapeutic fluid reservoir of the device. In one example, a housing of the IMD includes a protrusion that is configured to provide clearance for fluid communication between a propellant gas chamber pressure sensor and the propellant gas chamber.
