Abstract: This invention is an apparatus and method for delivering a treating element (22), such as a radiation source, through a catheter (60) to a desired site in avascular system of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongate flexible catheter tube (20) having proximal and distal portions, with a lumen (202) extending therebetween, and a diameter sufficiently small for insertion into the patient's vascular system. One or moretreating elements (22), such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal endportions under the force of a liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

Patent CA-2204661-A1 (CA)
Inventor: BURNWORTH DOUGLAS J
IPC: F16K5/04
Filed: 1997-05-06
Abstract: A valve has an elongated body open-ended, with a bore with a center line extending from one end of the body to the other. The bore is interrupted by a fluid tight partition, on both sides of which, ports extend through the wall of the body. An elliptical seat is formed on the outer surface of the body between the ports, the seat or channel being diagonal as viewed in side elevation with respect to the bore center line. A sleeve is rotatably mounted on the body. The sleeve has a smoothly cylindrical bore extending from am inlet end to a diagonal, radially outwardly extending annular shelf, between the first cylindrical bore and a second bore that is radially larger than the first bore. Channel-defining ribs extend parallel to the center line, from the shelf to a point short of the outlet end of the sleeve. The ribs have a radially inner face formed on the same radius as or slightly larger radius than the first bore. A seal in the elliptical seat in the closed position of the valve is in uniform engagement with the smooth cylindrical first bore throughout its perimeter, and in its open position is at least in part in engagement with the radially inner surfaces of the ribs, whereby in the open position, liquid flowing through the ports on one side of the body partition can flow in the channels defined by the ribs to the outlet ports, hence through the valve, but in the closed position, the engagement of the seal with the uniformly smooth, uninterrupted first bore prevents liquid from flowing past the seal.

Filed: 1996-01-16
Abstract: L'invention concerne un procédé et un appareil permettant, d'une part, de créer un instrument financier (figure 1) qui, en échange d'un règlement effectué auprès d'un organisme financier participant (figure 1), garantit le remboursement du capital et le paiement d'un taux d'intérêt variable sur une période déterminée et, d'autre part, la gestion d'un système de prêt à taux variable (figure 1). Le taux d'intérêt inscrit au crédit (figure 2) est établi chaque année (figure 2) pour l'année suivante (figure 2), dans une fourchette de taux minimal et maximal définis par contrat (figure 2). D'une manière générale, ce taux flotte en principe au-dessus du taux des fonds d'Etat à terme similaire, le prêteur (figure 1) disposant ainsi d'une nouvelle technique d'indemnisation pour les risques à long terme. En ce qui concerne l'emprunteur, ce système (figure 1) garantit et améliore sa solvabilité ainsi que la qualité du crédit puisqu'il permet de réduire le montant des intérêts (figure 1) en période de baisse des capacités financières. L'instrument financier (figure 1) peut être émis sous forme de titre de créance, de contrat de rente, de certificat de placement ou autre. Il peut être une obligation d'une compagnie d'assurances, d'une banque, d'une société à vocation unique, d'un groupe ou d'une autre entité.

Title: Wooden modular paneling for interior decoration
Inventor: DELORME CLAUDE
IPC: E04F13/10
Filed: 1997-07-30
Abstract: A decorative modular wooden panel for applying onto a wall comprises a series of elongated wooden strips disposed in a side-by-side with a tongue-and-groove assembly and being pre-assembled together by way of a pair of removable connecting bars engaged in channels defined on the rear side of the panel and extending transversely across the strips. Staples are used to secure the connecting bars to the panel thereby retaining the strips together. The panel is secured to the wall with screws driven through opposed ends thereof and into the wall. Moldings extending across the opposed ends of the panel are secured thereto with finishing nails such as to conceal the screws and the upper ends of the strips. As no adhesives are used to secure the panel to the wall, the panel can be removed from the wall with minimal damage to the wall. The width of the panel may be reduced by removing the connecting bars and then removing a required number of strips with the connecting bars being re-assembled to the remaining strips after having been shortened. Elongated vertical corner elements are provided for connecting two panels located on each side of a corner of the wall.

Title: Height-regulated hydropneumatic suspension
Inventor: OSTERWALDER FRANZ
IPC: B60G17/056
Filed: 1996-02-20
Abstract: The invention concerns a method and apparatus for-regulating the distance between the frame and a wheel unit or axle of a motor vehicle by means of a hydrodynamic suspension element by varying the volume of the damping liquid. The vehicle frame is sprung and damped at both sides of the vehicle relative to one or more wheel axles by means of hydropneumatic springs, wherein one of the volumes of the hydropneumatic springs is variable. In this arrangement, to increase the distance the static volume is supplemented by an additonal volume and to reduce the distance the static volume is reduced by a reduction volume.     Associated with one or more parallel-connected hydropneumatic springs is a metering unit which can add or withdraw at least one defined additional volume and/or reduction volume with respect to the instantaneous sum of the damping volumes of the associated hydropneumatic springs. The vehicle frame/wheel axle distance can be adjusted in the region of the hydropneumatic springs connected to the metering unit by detecting the condition of the metering unit by means of sensors arranged on the metering unit and readjusting to the reference functional condition.

Title: Perming method and device
Inventor: SHIGIHARA TAKANORI
IPC: A45D7/00
Filed: 1996-05-09
Abstract: A perming method for altering the shape of the hair by contact with an ultrasonically vibrating elastic body. When an alternating vibration is generated in the rod (cylindrical elastic body) (24), the elastic body Si(per se) does not rotate but causes another substance in contact with the periphery thereof to rotate thereabout. When, therefore, the substance is kept unrotatable, it comes to be vigorously treated by a spiral vibration. Accordingly, when the hair is in contact with the periphery of the elastic body, that part of the hair which is in contact with the periphery is vigorously treated in the circumferential direction of the elastic body by the vibration thereof. As a result, the cross-sectional shape of the hair is altered and the state of the hair under the vigorous treatment is kept as such, whereby the hair can be permed.
