Abstract: A system and method are disclosed for noninvasively diagnosing limb compartment syndrome by measuring a quantitative modulus of hardness. In the preferred embodiment, a nonmovable pressure probe mounted in the center of a movable spring loaded platform is applied against a limb compartment. Force is gradually applied to the probe and the platform, compressing a limb compartment. Pressure on the probe is measured as the probe pushes into the limb. The spring loaded platform displaces, and the distance of the probe tip to the platform is measured. This distance is the depth of compression into the limb by the probe. The relationship of incremental pressures in the probe and the corresponding distance of the probe tip to the platform for each pressure is plotted. A linear regression analysis is performed whose slope forms a quantitative modulus of hardness.

Abstract: An apparatus and method are disclosed for noninvasively diagnosing limb compartment syndrome by measuring a quantitative modulus of hardness. In the preferred embodiment, a low friction piston probe mounted within a platform is applied against a limb compartment. Pressure within the piston probe is increased while measuring the displacement of the piston plunger for each pressure applied. The relationship of incremental pressures in the piston to the displacements of the piston plunger are plotted and a linear regression analysis is performed whose slope forms a quantitative modulus of hardness. In an alternate, completely automated, continuous embodiment, a circumferential cuff secures the piston probe mounted within the a platform against the limb compartment, while the quantitative hardness modulus is formulated.

Abstract: A prosthetic heart valve which can be externally monitored is disclosed. In a first embodiment, the leaflets of the valve are magnetized, and the voltage induced in a coil juxtaposed thereto may be monitored. In a second embodiment, conductors are integrated with the leaflets. When the valve is then placed in a magnetic field, a voltage is induced in the conductors. The voltages induced in both valve configurations may be analyzed to indicate valve operation and conditions.
