Raman spectroscopy for monitoring drug-eluting medical devices |
摘要 |
The present invention provides low-resolution Raman spectroscopic systems and methods for in situ monitoring of drug-eluting devices in a lumen of a subject. A preferred system can employ multi-mode radiation in making in situ Raman spectroscopic measurements of the lumen and/or device. For example, a system can include a light source such as a multi-mode laser, and a light detector to measure spectral patterns and differentiates spectral features of drugs released in a target region. Drug-release curves can be extrapolated or otherwise predicted using the Raman spectrum taken during or subsequent to device insertion and/or activation.
