Title: Method and system for approximating distributed constant line
Inventor: YAMAGUCHI MASANORI
IPC: G06F17/50
Filed: 1998-08-31
Abstract: A lumped constant line approximating system capable of approximating a distributed constant line with required accuracy. The system receives inputs of object circuit information and analysis conditions (Steps 310, 320), calculates a product .gamma.1 of the propagation constant .gamma. and the line length 1 (Step 340), and calculates cosh .gamma.1 and sinh .gamma.1 by using the product .gamma.1 (Step 360) to obtain functions a n (.gamma.1), b n(.gamma.1) and c n(.gamma.1). Then , absolute values .delta.1, .delta.2 and .delta.3 of the differences between these functions and cosh .gamma.1 or sinh .gamma.1 are obtained, and compares the maximum .delta. among them with an error tolerance .epsilon.. If .delta. < .epsilon., the processing ends, while if .delta. < .epsilon. is not satisfied, the number of division is increased by 1, and the above processing is repeated, until the number n of division for approximation is determined (Step 370). Using the determined number of division, a ladder circuit is defined, for example, by cascading II circuits (Step 380), and stored (Step 400).

Patent CA-2304463-A1 (CA)
Title: Perfusion filter catheter
Inventor: MACOVIAK JOHN A
IPC: A61F2/00
Filed: 1998-09-23
Abstract: A perfusion filter catheter is used to capture potential emboli within the aorta during heart surgery and cardiopulmonary bypass. An expandable embolic filter assembly having fine filter mesh for capturing macroemboli and microemboli is mounted on a catheter shaft having a perfusion lumen with perfusion ports located upstream of the filter. The embolic filter assembly can be actively or passively deployed within the ascending aortic. An optional outer tube covers the embolic filter assembly to prevent premature deployment.  Radiopaque markers, sonoreflective markers and/or an aortic transillumination system are provided to monitor the position of the catheter and the deployment state of the embolic filter assembly. The embolic filter assembly is configured to maximize the effective filter surface area when deployed.  Embolic filter assembly configurations described include an elongated cone, a frustum of a cone, a trumpet-shape, a modified trumpet-shape, and helically, circumferentially and longitudinally convoluted shapes, as well as configurations having standoff members for centering the filter and holding the filter mesh away from the aortic walls when deployed. Oxygenated blood is perfused through the perfusion lumen and any embolic materials that might be dislodged are captured in the deployed embolic filter assembly. Embodiments are also described that combine the perfusion filter catheter with an aortic occlusion device, which may be a toroidal balloon, an expandable balloon or a selectively deployable external catheter flow control valve. The combined device allows percutaneous transluminal administration of cardiopulmonary bypass and cardioplegic arrest with protection from undesirable embolic events.

Title: X-ray absorbing material and variants
Inventor: PETCHENKIN VALERIY IVANOVICH
IPC: G21F1/10
Filed: 1998-09-24
Abstract: The present invention relates to an X-ray absorbing material which can be used in medicine as well as in the production of special protection clothes, protection screens, housings, protection coatings and isolation materials. In a first embodiment, the material uses as a filler a poly-dispersed kneading-segregated mixture containing metallic particles having a size of between 10 -9 and 10 -3 m, wherein said particles are bonded to the surface of a textile base. The density of the material is defined by the relation q N = (0.01 - 0.20)q P where q N is the density of the X-ray absorbing material as a whole while q P is the density of the material used for the particles of the X-ray absorbing filler. In a second embodiment, this invention uses as a filler the above-mentioned mixture though the particles are surrounded by the volume of a matrix made of a compound that solidifies under atmospheric pressure. The total mass of the poly-dispersed and segregated mixture is defined by the relation M = (0.05 - 0.5)m where M is the total mass of the X-ray absorbing poly-dispersed and segregated filler, while m is the equivalent mass of the filler material which is equal by its protection properties to the mass M. In a third embodiment, this invention uses as a filler the above-mentioned mixture though the particles are bonded to an intermediate substrate consisting of a textile base and surrounded by the volume of a matrix.
