Abstract
Embodiments of the invention are related to monitoring devices and methods with osmometric sensors, amongst other things. In an embodiment, an implantable heart failure monitoring system includes an implantable osmometric sensor configured to generate a signal corresponding to osmotic strength of a bodily fluid. The osmometric sensor includes a rigid wall member defining an enclosed volume resisting deformation, the rigid wall member comprising a semi-permeable membrane. The sensor also includes a signaling element comprising a first side, a second side, and a plurality of dimples configured to resist deformation until a threshold differential exists between the first and second sides. Other aspects and embodiments are provided herein.
