Method for in vivo measurement of coagulation rate
First Claim

1. A method for measuring in vivo coagulation rate, comprising:
- clamping a fold of organic tissues so that a target blood vessel contained in the organic tissues is closed at a downstream point and an upstream point spaced from one another;
after clamping the old of organic tissues, directing waveform energy through the fold of organic tissues; and
analyzing waveform energy transmitted at least partially though the fold of organic tissues to determine a state of coagulation of blood trapped in the blood vessel between said downstream point and said upstream point.

Abstract
In a method for measuring in vivo coagulation rate, a fold of organic tissues is clamped so that a target blood vessel contained in the organic tissues is closed at a downstream point and an upstream point spaced from one another. Waveform energy is then directed through the clamped organic tissues. Waveform energy transmitted at least partially through the organic tissues is analyzed to determine a state of coagulation of blood trapped in the blood vessel between the downstream point and upstream point.

14. A device for measuring in vivo coagulation rate, comprising:
-
a first clamping element and a second clamping element; an actuator mechanism operatively connected to said first clamping element and said second clamping element for shifting said first clamping element and said second clamping element towards one another, said first clamping element, said second clamping element, and said actuator mechanism being configured to clamp the blood vessel first at said downstream point and subsequently at said upstream point; a source of waveform energy mounted to one of said first clamping element and said second clamping element; a sensor of said waveform energy mounted to one of said first clamping element and said second clamping element; and an analyzer of said waveform energy operatively connected to said sensor for determining a time of onset of blood coagulation in a blood vessel clamped between a downstream point and an upstream point by said first clamping element and said second clamping element. - View Dependent Claims (15, 16, 17)
