| 20080228428 | SYSTEM AND METHOD FOR THE NON-DESTRUCTIVE ASSESSMENT OF THE QUANTITATIVE SPATIAL DISTRIBUTION OF COMPONENTS OF A MEDICAL DEVICE - A method and system for the non-destructive analysis of medical devices uses a confocal Raman microscope and other non-destructive analytical tools to assess the spatial distribution of components of an object such as the distribution of an active pharmaceutical ingredient (API) within a polymer matrix. In a preferred embodiment, confocal Raman spectroscopy was used to differentiate each component found in the sirolimus-eluting coronary stent. The unique spectral features identified for each component were then used to develop three separate calibration curves to describe the solid phase distribution found on drug-polymer coated stents. The calibration curves were obtained by analyzing confocal Raman spectral depth profiles from a set of 16 unique formulations of drug-polymer coatings sprayed onto stents and planar substrates. | 09-18-2008 |
