Abstract: The present invention is a disposable sensor for use with a device that quantifies analytes in a gaseous sample. It comprises (i) a sensing element, (ii) a means for interfacing the disposable sensor with a gas analysis device, and (iii) a housing. When used with a device that can quantify the concentration of an analyte in a gas sample, the present invention facilitates the use of exhaled breath analysis as a clinical tool.

Abstract: The flow rate of a gaseous sample of exhaled breath through an analytical device is controlled by a pump, and in certain embodiments two pumps. Placement of the analyte sensor in a secondary stream branching off of the primary stream through the device offers further control over the manner, duration, and quantity of the breath that is placed in contact with the sensor.

Abstract: A system and method for controlling the flow rate of a gaseous sample in an exhaled breath analysis system is disclosed. Two embodiments are described in this patent: a single pump embodiment and a dual pump embodiment. In each of these embodiments, a pump or pumps are used to control the flow rate of the breath sample as it moves through the analysis system. Also, the system includes means to conduct side stream, stopped flow analysis.

Abstract: A device, system and method for diagnosing and treating a patient is provided where a functional device is attached to a stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a substance delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible for removal and replacement. In one embodiment, an endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall with the assistance of a suction used to stabilize the tissue of the stomach wall. The device includes a chamber for receiving tissue of the stomach wall for attachment where a vacuum pressure is applied through the chamber to draw the tissue into the chamber.

Abstract: The present invention is a system and method of conditioning the sample and surrounding environment of an exhaled breath sensor. It includes (i) using a particular molecular sieve for a triple purpose: (a) maintaining the sensor at a constant relative humidity during storage, (b) equilibrating the incoming breath stream to the same relative humidity as the sensor, and (c) eliminating the analyte from the environment around the sensor during storage. The present invention also includes removal of interfering components from the exhaled breath, such as carbon dioxide, as well as a thermal management technique.

Abstract: Systems and methods are provided for aerosolizing a pharmaceutical formulation. According to one method, respiratory gases are prevented from flowing to the lungs when attempting to inhale. Then, respiratory gases are abruptly permitted to flow to the lungs. The flow of respiratory gases may then be used to extract a pharmaceutical formulation from a receptacle and to place the pharmaceutical formulation within the flow of respiratory gases to form an aerosol.

Abstract: An upright steerable vacuum cleaner comprised of a handle, body, nozzle base and air duct therein further having a swivel joint at the junction of the nozzle base and body. The swivel joint or steering mechanism comprises a trunnion pivotably connected to the main air duct of the vacuum. The pivotable connection causes the nozzle base of the vacuum to turn right with a clockwise twist of the vacuum handle and turn left with a counter-clockwise twist of the vacuum handle. A locking mechanism is provided for preventing rotation of the trunnion with respect to the air duct.
