EMBEDDED PHOTONIC SYSTEMS AND METHODS FOR IRRADIATION OF MEDIUM WITH SAME

摘要

System and method for irradiating a region of interest of a medical device, implanted in a biological tissue, and the surrounding tissue. The system includes a translucent wall having an optically diffusing component and, optionally, an associated source of light embedded therein. The optical diffuser is optionally configured to outcouple light with a uniform spatial distribution and may include a network of biocompatible waveguides. The system may include a catheter with a distal end with an embedded diffuser that outcouples light delivered from the external source through a spiral of optical fiber, buried in the wall of the catheter. The system may include a biocompatible layer permanently embedded into the biological tissue and containing quantum dots that are activated wirelessly, through the layer, to irradiate the surrounding tissue from inside. Such a layer does not need to be removed from the tissue after irradiation of the tissue has been accomplished.

1. An article of manufacture comprising
a body defined by a wall and having a region of interest (ROI) therein, said wall configured to deliver excitation power from outside of the body through the wall to the ROI; and an element embedded into the wall at the ROI, said element configured to form a spatial distribution of electro-magnetic radiation (EMR) in response to excitation power delivered from outside of the body through the wall to the ROI.
