Title: System and method for multiple site biphasic stimulation to revert ventricular arrhythmias
Inventor: MOWER MORTON M
IPC: A61N1/368
Filed: 1999-03-04
Abstract: An anti-reentry apparatus and method for reverting ventricular arrhythmias. Biphasic stimulation is applied at multiple ventricular sites to revert arrhythmias caused by reentry, particularly multiple random reentry. In the preferred embodiment, the first phase of biphasic stimulation is anodal, and is at a maximum subthreshold amplitude. The anodal phase preconditions the myocardium to accept the second phase (cathodal) such that less electrical energy is required to reach the threshold amplitude to produce depolarization. The anodal phase stimulation may have a shape over time that is square wave, ramped, or a series of short square wave pulses. Multiple electrodes located at multiple ventricular sites may be stimulated simultaneously, or they may be sequentially stimulated over time in a manner mimicking the normal progress pattern of cardiac depolarization. The multiple ventricular electrodes may stimulate from internal or external surfaces. One or both ventricles may receive biphasic stimulation from multiple electrodes. The invention also may be practiced with respect to atria.

Patent CA-2330063-A1 (CA)
Inventor: CANTRILL DEAN
IPC: C01B13/02
Filed: 2000-12-29
Abstract: The present invention called a patient ventilator oxygen concentration system advantageously utilizes an existing suitable air supply and provides a modular oxygen concentrator that uses the existing air supply and a medical grade air filtration package for providing medical grade using the existing air supply.      The oxygen concentrator has multiple bed pairs which can be selectively activated. If one of the multiple bed pairs is not activated, the excess air provided by the existing air supply is filtered and medical grade air is supplied instead of oxygen gas for use with patient ventilators. Advantageously, the present invention obtains a large increase in medical grade air flow at the expense of very little oxygen flow while maintaining oxygen purity using the existing air supply. It is not possible to make this air/oxygen trade-off using a conventional pressure swing absorption (PSA) system for maintaining oxygen purity. The present invention provides a pneumatic circuit which is capable due to a modular bed design. Each bed pair uses approximately three SCFM (80 SLPM) to produce five SLPM of oxygen. Shutting down a bed pair reduces the oxygen flow but increases the available compressed air to be converted into medial grade air.  The remaining bed pair maintains their oxygen purity because the compressed air supply is not reduced. By contrast, if a single bed pair system were used, reducing the oxygen output would not free up a significant amount of feed air to be converted into medical grade air. If the demand for medical grade air increased beyond rated flow, the oxygen purity would decrease due to the transfer of feed air from the PSA bed pair to the medical grade air system.

Title: Apparatus and method for closed-loop intracranial stimulation for optimal control of neurological disease
Inventor: DILORENZO DANIEL J
IPC: A61N1/36
Filed: 1999-08-05
Abstract: This invention is a neurological control system (999) for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a "nervous system component". The neurological control system generates neural modulation signals delivered to a nervous system component through one or more intracranial (IC) stimulating electrodes (37) in accordance with treatment parameters. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors (247), each configured to sense a particular characteristic indicative of a neurological or psychiatric condition. Neural modulation signals include any control signal which enhances or inhibits cell activity. Significantly the neurological control system considers neural response, in the form of the sensory feedback, as an indication of neurological disease state, and/or responsiveness to therapy, in the determination of treatment parameters.

IPC: G01N21/71
Filed: 1998-09-21
Abstract: The present invention pertains to the construction of analytic instruments and can be used for analysing natural and industrial water, biological samples, geological samples and air. The purpose of this invention is to reduce substantially the power used by the atomiser and the analyser, and to increase the number of objects that can be analysed. To this end, the method for the thermionic atomisation of a sample involves carrying out an ionic sputtering of the sample from the cathode in a low-pressure discharge. The cathode is heated by the discharge to a temperature of between 800 and 1400 ~C, while the ballast gas consists of Kr or Xe under a gas pressure of 10 to 15 torrs. The thermionic atomisation device includes an atomiser arranged in a gas-discharge chamber filled with an inert gas. The atomiser is made in the form of a hollow, cylindrical, metallic and thin-wall cathode. In order to reach this goal, the method involves using a thermionic atomisation device which, in an efficient embodiment, consists of the above-mentioned gas-discharge atomiser, i.e. a hollow, metallic and thin-wall cathode. This mechanism enables the sputtering and atomisation of the sample in a short time (0.2 to 1 sec.), thus lowering the detection limits while eliminating matrix effects.

Filed: 2001-04-25
Abstract: Endophilin I is a brain-specific protein functioning in clathrin-mediated endocytosis. The present invention is based on the finding that the rat germinal center kinase-like kinase (rGLK), a member of the germinal center kinase (GCK) family of c-jun N-terminal kinase (JNK) activating enzymes, is a novel endophilin I-binding partner. In a first aspect of the present invention, the novel interaction between endophilin I and rGLK is put to use in a novel screening assay. In a second aspect of the present invention, the interaction between endophilin I and GLK is modulated for therapeutic purposes, namely for the prevention and/or curtailment of neurological disorders associated with the JNK pathway.    JNK-mediated neuronal cell death is believed to play an important role in injuries and diseases involving neuronal degeneration, such as Huntington's disease.

Abstract: Attachment of a bridge (18) and temple hinge (32) to the lens (12) of eye glasses. The attachment is accomplished by providing a pair of apertures (30) of a selected configuration in each lens adjacent to the outer and inner surface of the lens, a bushing (24) conforming to the lens apertures with a tapered aperture through the center thereof from front to back end tapering the distal ends of the bridge and temple hinges. This combination when in place in the lenses apertures provides a friction lock between the lens and the bridge and temple hinge.      The taper can be in the range of 1 to 45 degrees. In another embodiment the lens can also have a tapered aperture either convergent from the front to the back of the lens or divergent from the front to the back of the lens. Ideally a taper of 4.5 degrees in the bushing is preferable with less taper in the lens apertures when tapered lens apertures are utilized. The taper can take the form of a frusto conic section, a cylinder, a rectangular or triangular in cross section. The distal ends of the bridge and temple hinge can be inserted either from the front of the lens toward the back or from the back toward the front. The distal ends of the temple hinge can be inserted directly into the aperture within the bushing for attachment or can additionally be bent formed to provide a bias between the outer surface of the lens adjacent the aperture for non rotational support. In some applications a notch is provided at the outer lens surface and the bent formed portion of the temple hinge is nested therein for additional mechanical support and to increase the resistance of relative rotation of the bridge or temple hinge.
