DEFINITION

Classification: 600/494

Pulse-induced pressure fluctuation in occluder generates electric signal:

(under subclass 493) Subject matter wherein the electric signal is generated in response to pulse-induced pressure variation within a force applying means for closing a blood

vessel.

(1) Note. Apparatus included in this subclass generally comprises a transducer capable of sensing the pressure increase which occurs within an inflatable arm band when flow of blood through an arm battery causes movement of skin overlying the artery and underlying the arm band.
