Methods and Systems for Determining Volume Flow in a Blood or Fluid Conduit, Motion, and Mechanical Properties of Structures Within the Body
First Claim
1. A system for determining blood flow rate in a vessel which communicates blood between two locations of a patient, the system comprising:
- a conduit in fluid communication with the vessel;
at least one sensor in communication with the vessel for determining differential blood pressure (? P) between two or more locations within the vessel; and
a processor operably connected to the at least one sensor for processing the ? P to obtain blood flow rate within the vessel.

Abstract
The present invention provides a system for determining blood flow rate in a vessel which communicates blood between two locations of a patient, the system comprising: a conduit in fluid communication with the vessel; at least one sensor in communication with the vessel for determining differential blood pressure (? P) between two or more locations within the vessel; and a processor operably connected to the at least one sensor for processing the ? P to obtain blood flow rate within the vessel.
A method for determining blood flow rate in a vessel which communicates blood between two locations of a patient, the method comprising: diverting blood from the vessel at a diversion point to obtain a flow of diverted blood in a conduit; determining differential blood pressure (? P) of the diverted blood through the conduit; and processing the ? P to obtain blood flow rate within the vessel.
