Abstract: A medical-treatment electrode assembly includes at least three spaced-apart electrodes contactable with patient tissue and includes at least three leads electrically connected one each to a corresponding one of the electrodes. The leads are electrically connectable to a medical radio-frequency (RF) generator.

Abstract: A minimally invasive method of placing a delivery device substantially adjacent to vascular tissue and a device for use with such a method are disclosed. The delivery device may be a flexible biological construct with a flexible tethering means. The delivery device may be percutaneously inserted near vascular tissue such as, for example, peritoneal tissue. When the delivery device has been inserted, the tether may be used to pull the delivery device toward the vascular tissue and secure the device thereto. Contact between the front surface of the delivery device and the vascular tissue may be maintained by making and keeping the tether substantially taut. The delivery device may serve accomplish sustained delivery of active agents.

Abstract: Method for non-invasive detection of the concentration of a constituent in blood of a living animal includes the steps of irradiating a body part of the animal with intensity-modulated radiation over a continuous spectrum; determining the intensity of radiation emitted from the body part at wavelength ranges within the continuous spectrum; and using the determined intensity to calculate the concentration of the constituent. A radiation source including a radiating bulb and a chopper for periodically interrupting radiation emitted from the bulb may be provided.
