Patent WO-0182810-A1 (WO)
Title: Catheter
Inventor: SANTOIANNI DOMENIC
IPC: A61B19/00
Filed: 2000-04-27
Abstract: Cathéter utilisable pour l'ablation de tissus, par exemple, pour traiter une arythmie cardiaque, comprenant une poignée, une tige dont la forme est susceptible d'être modifiée, et un segment d'ablation distal. La tige conserve une première position jusqu'à ce qu'elle soit manipulée pour prendre une autre position en exerçant une pression manuelle modérée. La tige comprend des éléments plastiquement déformables et peut prendre une forme en conformité avec un parcours d'insertion ou une anatomie particulière d'un patient, en vue d'accéder à un site pour une ablation. Une fois mise en forme, la tige conserve sa forme lorsque le cathéter est inséré ou manipulé vers l'emplacement de traitement de tissu prédéterminé, et le segment distal est poussé de manière à venir en contact avec le site du tissu. Un mécanisme de déflexion peut être prévu pour faciliter la navigation ou pour amener le segment d'ablation en contact en contact de forme avec la cible du tissu. Selon une variante d'exécution, une seconde tige, ou tige auxiliaire, s'étend distalement à partir du segment d'ablation, permettant au segment d'être introduit ou tiré, en passant devant le tissu d'occlusion, vers un site de tissu éloigné. En tenant l'extrémité de la seconde tige, le segment d'ablation flexible peut être, soit tendu, soit tiré vers l'intérieur, soit ployé et poussé vers l'extérieur, vers un site de traitement tel qu'une région de la paroi épicardique postérieure, procurant ainsi un contact plus efficace pour une vaste gamme de dispositions et d'orientations des tissus. Suivant une autre variante, un écran thermique s'étend sur une partie du segment d'ablation, protégeant ainsi le tissu adjacent d'un dommage, tout en exposant encore efficacement le tissu cible à une énergie d'ablation. L'écran peut être tourné ou déplacé axialement en vue de délimiter une aire de contact cryogénique et d'obtenir une meilleure protection des structures environnantes de tissus dans les régions cibles de traitement par occlusion ou à distance.

Inventor: LAI SHUI T
IPC: H01S3/06
Filed: 1990-03-28
Abstract: ABSTRACT     A single cavity laser device comprises a diode pumped laser medium having a relatively high gain but a relatively low power.  With this medium, a control laser beam is generated.          Also positioned in the cavity is a second laser medium having a relatively large gain volume which is pumped by an array of laser diodes at a relatively low gain to created a reservoir of excited state ions.  Positioned between these two diode pumped laser mediums is a beam expander which focuses the control laser beam onto the second laser medium to substantially fill the gain volume of the second laser medium.  Stimulation of the excited ions in the gain volume of the second laser medium by photons in the control beam efficiently generates a laser beam of relatively high power.

Title: Fatty spread containing native whey protein
Inventor: OCHMANN RAINER
IPC: A23D7/015
Filed: 1990-05-14
Abstract: A B S T R A C T               FATTY SPREAD CONTAINING  NATIVE WHEY PROTEIN            The invention relates to low fat spreads containing native, that is not substantially denatured, whey protein.            It is commonplace to Pasteurise the process stream in spread production under time/temperature conditions as to denature whey protein.  The effect of denaturation is precipitation which removes the functional properties of the whey and can lead to a "mealy" product.            The invention provides a 35-80% fat phase W/O spread in which the water phase has pH 4.5-5.5, contains 0.5-10.0%wt of an undenatured whey protein, and has a lactose content below 20%wt of total protein content.            Such products have an improved long-term resistance to microbiological spoilage, avoid "mealyness" and utilise functional properties of the whey protein, such as water-binding ability and some effect as an emulsifier.

Title: Method of producing fresh meat in which substantial moisture loss during production is reduced
Inventor: ENGLER SID
IPC: A23B4/08
Filed: 1990-07-26
Abstract: A method of producing fresh meat is disclosed, in which substantial  moisture  loss during  production  is  effectively reduced.   The method  comprises the steps of applying liquid to the surface of a carcass; subjecting the carcass to a supercold environment for a period of time sort enough to substantially prevent freezing of the outermost layers  of the flesh of the carcass,  but long enough to allow for formation of an ice layer around the carcass.  Once the ice layer is formed, the carcass is passed  into  refrigeration  chamber  for  further  cooling.  The carcass is kept in the refrigeration chamber for a period fo time long enough to lower the temperature of the flesh to a point where substantial deterioration of the flesh is prevented,  but short enough to prevent freezing of the flesh.
