Abstract
In this Phase I SBIR Koronis Biomedical Technologies proposes to develop and evaluate a fully
implantable wireless device that monitors left ventricular pressure and volume P V in rodent studies
Transgenic models of heart disease have been created through hypothesis driven research on rodents that
seeks to both identify mechanistic pathways in academic research and support the development of novel
compounds and medications by large pharmaceutical companies As a result it has become increasingly
important to accurately and thoroughly evaluate cardiac function in the mouse and rat model Although
implanted telemetric pressure systems have been successfully commercialized for both mice and rats a
device that also measures real time volume in a free roaming rodent has been absent to date The
proposed miniature lightweight fully implanted device will collect pressure and volume measurements
using an admittance measurement technique and wirelessly transmit the measured data to a nearby base
station Narrative
Rodent models of heart disease are used by academic scientists and pharmaceutical companies to prove
drug safety and efficacy There is a need for a telemetric left ventricular pressure volume system to assess
rodent cardiac parameters
