Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An implantable fluid delivery device comprising: a reservoir configured to store a therapeutic fluid; a housing defining a chamber configured to at least partially surround the reservoir, wherein the chamber is configured to be filled with a propellant gas configured to regulate a pressure within the reservoir; and a pressure sensor configured to sense a pressure within the chamber, wherein the housing comprises a protrusion in an annular wall of…
