Abstract: An RFID-based anemia detection sensor that integrates a paper-based diagnostic device with a passive Ultra High Frequency (UHF) RFID tag. Differences in red blood cell (RBC) count in a patient's blood manifests itself as a controlled time-dependent change in the tag's signal response. In one embodiment, the sensor is capable of reliably differentiating between blood having 20, 30, 40 and 50 percent RBC concentration by volume, which is indicative of anemic vs. healthy blood. In another embodiment, the sensor is read using standard RFID equipment allowing for large-scale automated screening of blood specimens.

Abstract: Agents and devices for affecting nerve function are described. In some variations, a combination of agents, e.g., a cardiac glycoside, an ACE inhibitor, and an NSAID are delivered to affect nerve function. The agent may be delivered locally in a site-specific manner to a targeted nerve or portion of a nerve. For example, the agent may be delivered locally to the renal nerves to impair their function and treat hypertension. One variation of a delivery device includes one or more needle housings supported by a balloon. A delivery needle is slidably disposed within a needle lumen of each needle housing.
