SYSTEM AND METHOD FOR NON-INVASIVE INSTANTANEOUS AND CONTINUOUS MEASUREMENT OF CARDIAC CHAMBER VOLUME
First Claim
1. A medical device for determining a change in the spatial configuration of a heart, comprising:
- at least one antenna adapted to be located adjacent a portion of the heart; and
a sensing unit capable of resolving a change in reflected signals, wherein said sensing unit of the medical device is capable of resolving a change in reflected signals that are functionally related to a change in cardiac ventricular volume.

Abstract
A system and method for non-invasive and continuous measurement of cardiac chamber volume and derivative parameters including stroke volume, cardiac output and ejection fraction comprising an ultrawideband radar system having a transmitting and receiving antenna for applying ultrawideband radio signals to a target area of a subject'"'"'s anatomy wherein the receiving antenna collects and transmits signal returns from the target area which are then delivered to a data processing unit, such as an integrated processor or PDA, having software and hardware used to process the signal returns to produce a value for cardiac stroke volume and changes in cardiac stroke volume supporting multiple diagnostic requirements for emergency response and medical personnel whether located in the battlefield, at a disaster site or at a hospital or other treatment facility.
