An implantable ischemia detection device in which a broadband light source produces a continuous, visible, broadband light illuminating capillary sites within a well localized target tissue is provided. Light backscattered by the target tissue is collected by a sensor, allowing for an index of ischemia to be determined, and subsequently transmitted by a sending unit. Optionally, the device may be provided with an internal power source, the entire device encapsulated by a biocompatible shell to add long-term safety while implanted at a target tissue site. |
