Osmometric heart monitoring device and methods
First Claim
1. An implantable heart failure monitoring system comprising:
- an implantable osmometric sensor configured to generate a signal corresponding to osmotic strength of a bodily fluid, the osmometric sensor comprisinga rigid wall member defining an enclosed volume resisting deformation, the rigid wall member comprising a semi-permeable membrane;
a signaling element comprisinga transducing structure comprising;
a first side;
a second side; and
a plurality of dimples configured to resist deformation until a threshold differential exists between the first side and second side of the transducing structure.
