069 Wireless Physiologic Telemetry for Interventional MRI
NHLBI SBIR/STTR Contract Topic
(Fast-Track proposals will be accepted)
Number of anticipated awards: 1
Magnetic resonance imaging (MRI) has potential to revolutionize minimally invasive surgery and interventional procedures by affording improved tissue visualization without conventional surgical incisions. Many such procedures will be conducted under both X-ray and MRI guidance. Such procedures require high fidelity hemodynamic recording of physiological signals such as electrocardiography and invasive blood pressure, with seamless bidirectional transfer between X-ray and MRI. To date there are no suitable commercial solutions.
A wireless telemetry system would allow acquisition of hemodynamic signals (multichannel electrocardiography, invasive blood pressure, noninvasive hemoglobin saturation, temperature, etc.) safely in both the MRI and X-ray fluoroscopy environments, and allow continuous monitoring during transportation between the two.
The system must conform to the following specifications:
Proposals to address electrocardiogram artifacts from magnetohydrodynamic effects are welcomed but not required.
The sponsoring NIH laboratory is willing to provide access to acquired physiological signals without preprocessing; alternatively the offeror should have access to such a laboratory independently for development and for testing.
The Phase I deliverable is a working prototype to support investigational X-ray and MRI guided interventional procedures in patients. This includes ten ECG leads for use in X-ray and at least six ECG leads for use in MRI, two invasive pressure transducers, and hemoglobin saturation.
The Phase II deliverable is a commercial-grade clinical system.
