Abstract: An analysis, measurement, and data reduction system for carrying out a noninvasive urodynamic analysis of the human male or female urogenital tract. The apparatus comprises a urethral extender device, a vacuum system, a flow and pressure measuring and control system, a parameter variation device, and a control, acquisition and analysis system capable of the analysis of time dependent urine pressure and flow data so as to obtain clinically significant parameters, including bladder pressure and resistance and compliance parameters for the components of the urogenital tract.

Abstract: A remotely controlled drug delivery device administers a dose of a drug, agent or microbicide using a gas pressure delivery system. The device stores multiple doses of the drug or agent. A toroid shaped housing includes three chambers, a gas chamber containing a pressurized gas, a drug storage chamber containing the drug or agent, and an expandable chamber for delivering the drug from the drug storage. The device includes an electronic controller for opening a valve connecting the gas chamber to the expandable chamber for a predetermined period of time in order to deliver a predetermined dose of the drug. The controller communicates with a remote control device via radio frequency. The remote control device sends a signal to the controller, which causes a dose to be delivered. The controller returns a signal to the remote control device indicating that the dose has been delivered and a signal indicating when the device needs to be removed for maintenance.

Abstract: A clinical whole blood viscometer and a method for obtaining instantaneous whole blood viscosity measurements over a wide range of shear rates with a single blood sample is described. A conventionally acquired sample of fresh blood is drawn from a patient and introduced into the viscometer so as to establish viscous flow, the viscosity measurements being taken by remote sensing devices activated by compliant solids or gases in contact with the sample.
