Abstract
An apparatus for intravascular imaging to detect and characterize early stage, unstable coronary arty plaques. The detector works by identifying and localizing plaque-binding beta-emitting radiopharmaceuticals.
Claims23
An intravascular imaging catheter comprising:
- a catheter body;
- a first scintillator that generates light within a first emission spectrum;
- a second scintillator that generates light within a second emission spectrum;
- wherein the first emission spectrum is offset in wavelength from the second emission spectrum, wherein the first and second scintillator are disposed on the catheter body;
- and
- an optical delivery device that can transmit light from the first scintillator and second scintillator to a photodetector.
3 more elements
A method of characterizing unstable plaque a body lumen, the method comprising:
- positioning first and second scintillators at a target site in the body lumen;
- generating light in at least one of the scintillators in response to radiation attached to the unstable plaque, wherein light generated in the first scintillators has a first emission spectrum and light generated in the second scintillator is in a second emission spectrum, wherein the first emission spectrum is offset in wavelength from the second emission spectrum;
- and
- transmitting the light generated in the first and second scintillators down an optical fiber.
