First Claim
Patent Images
1. A method of addressing vascular stenotic lesions in the vascular system of a patient, the method comprising:
- determining the geometry of an occluded zone in a blood vessel;
estimating pressure drop through the occluded zone using output from a pressure drop algorithm; and
determining if the occluded zone needs treatment based on the estimated pressure drop.

Abstract
A method and apparatus are provided for addressing vascular stenotic lesions. The geometry of a stenotic lesion zone is determined and is used to determine pressure drop of blood flow across the lesion zone or a portion thereof. The pressure drop value is used to determine a treatment regimen for the stenotic lesion zone. The geometry if preferably a three dimensional geometry. The apparatus provides pressure drop values to a physician so the physician can treat the patient if treatment is needed and provides direction for treatment options as to type and degree.

10. An apparatus for determining a vascular treatment regimen for an occluded blood vessel, said apparatus including:
-
a data processing apparatus including a processor and a memory, the data processing apparatus being programmed to provide output data representative of pressure drop in a blood vessel based on input data representative of the geometry of a portion of the blood vessel; data input means operably connected to the data processing apparatus to permit data input into the data processing apparatus; and data output means operably connected to the data processing apparatus to permit data output from the data processing apparatus. - View Dependent Claims (11, 12, 13, 14)
