Abstract: A fluidic infusion system introduces a select liquid chemical into the environment surrounding the functional end of an in vivo catheter or probe. The catheter/probe typically has a-sensor or electrode positioned near or at its closed distal end. A plurality of spaced radial openings are formed in an appropriate pattern adjacent to the end of the catheter/probe for introducing the select liquid chemical into the appropriate environment. The catheter/probe has at least one lumen extending through its length for directing the liquid chemical from a controlled pump to the radial openings. The openings are positioned within the catheter/probe so that when the catheter/probe is inserted into the appropriate environment, e.g.

Abstract: A glucose monitoring system continuously measures the glucose concentration in a patient's blood, provides an indication of the rate of change of such concentration, and determines whether the measured concentration and rate of change are within certain preset limits. If not, an audible and/or visual alarm signal is generated. The glucose monitoring system includes a glucose sensor adapted to be inserted into the venous system of the patient, where it responds to blood glucose and produces sensor signals related to the glucose concentration. The sensor signals are delivered through a suitable interconnect cable to a glucose monitor. In one embodiment, the interconnect cable includes a contactless connector that electrically isolates the glucose sensor from the monitor, and reduces the number of conductors required to interface with a plurality of sensors. The glucose monitor interprets the sensor signals by applying a previously determined calibration to quantitatively determine the blood glucose value.
