Abstract
Abstract Vulnerable plaque is identified through a diagnostic method by identifying pathologic markers such as C-reactive proteins or pH change generated by the pathologic site. First and second detectors are advanced through a blood vessel with each of the detectors selected to detect the pathological marker. The detectors are spaced apart while seeking the marker. Differential concentration of the pathological marker as measured by the first and second detectors indicates a presence of the pathological site in proximity to at least one of the detectors.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
211 words
A diagnostic method for identifying a pathologic site in a blood vessel, of a patient's vasculature wherein said pathologic site is characterized by a generation of a pathologic marker, said method comprising: advancing a first detector and a second detector into said vasculature with each of said first and second detectors selected to detect an intensity of said marker, said detectors being arranged to avoid contact with a wall of the vasculature; spacing said first and second detectors apart while said detectors are seeking detection of said marker; advancing at least one of said detectors through said vessel with each of said detectors measuring an intensity of said marker at a location in said vasculature of each of said detectors; and comparing an intensity of said marker as measured by each of said detectors and noting an increase in intensity of said marker as measured by said at least one of said detectors relative to an intensity of said marker as measured by the other of said detectors; wherein a differential of intensity of said marker between said first and second detectors indicates a presence of said pathologic site in proximity to said at least one of the detectors and with said differential compensating for a systemic presence of said marker.
Claim 2
Dependent Claim
211 words
A diagnostic method for identifying a pathologic site in a blood vessel, of a patient's vasculature wherein said pathologic site is characterized by a generation of a pathologic marker, said method comprising: advancing a first detector and a second detector into said vasculature with each of said first and second detectors selected to detect an intensity of said marker, said detectors being arranged to avoid contact with a wall of the vasculature; spacing said first and second detectors apart while said detectors are seeking detection of said marker; advancing at least one of said detectors through said vessel with each of said detectors measuring an intensity of said marker at a location in said vasculature of each of said detectors; and comparing an intensity of said marker as measured by each of said detectors and noting an increase in intensity of said marker as measured by said at least one of said detectors relative to an intensity of said marker as measured by the other of said detectors; wherein a differential of intensity of said marker between said first and second detectors indicates a presence of said pathologic site in proximity to said at least one of the detectors and with said differential compensating for a systemic presence of said marker.
Claim 3
Dependent Claim
34 words
A method according to claim 1 comprising narrowing a spacing between said first and second detectors after said indication of said presence of said pathologic site to more narrowly focus on said pathologic site.
Claim 4
Dependent Claim
14 words
A method according to claim 1 wherein said pathologic site is a vulnerable plaque.
Claim 5
Dependent Claim
14 words
A method according to claim 1 wherein said pathologic marker is a C-reactive protein.
Claim 6
Dependent Claim
16 words
A method according to claim 1 wherein said pathologic marker is a hydrogen ion concentration (pH).
Claim 7
Dependent Claim
15 words
A method according to claim 1 wherein said pathologic marker is an increase in temperature.
Claim 8
Dependent Claim
15 words
A method according to claim 1 wherein said pathologic marker is a localized inflammation marker.
Claim 9
Dependent Claim
19 words
A method according to claim 1 wherein each of said first and second detectors is placed in said vessel.
