Patent CA-2208793-A1 (CA)
Inventor: SOPER JON C
IPC: A23P10/30
Filed: 1995-12-19
Abstract: This invention is directed to a method of forming microencapsulated food or flavor capsules as well as the capsules produced by the method. The method includes providing food or flavor particles to be encapsulated, and forming a mixture of a warm water fish gelatin and the food or flavor particles in aqueous media. The method further includes microencapsulating the particles with the gelatin at elevated temperatures by complex coacervation to form the microencapsulated capsules. If desired, the method may further include the step of separating the capsules. In a preferred form, the method is conducted at a temperature of about 33 ~C to about 35 ~C. Preferably, the warm water fish gelatin used in the encapsulation method has a bloom of from about 150 to about 300 bloom, more preferably from about 250 to about 300 bloom. Many different kinds of food or flavor particles may be used, such as for example, vegetable oil, lemon oil, garlic flavor, apple flavor or black pepper. The invention also is directed to the food or flavor capsules produced by the method.

Title: Improved two-phase dispensing systems utilizing bellows pumps
Inventor: COLLIAS DIMITRIS IOANNIS
IPC: B05B7/00
Filed: 1995-07-20
Abstract: The present invention provides an improved manually operated dispensing system for dispensing a liquid product in atomized or foam form. More particularly, the present invention provides an improved manually operated pump for use in such dispensing system which incorporates at least one collapsible bellow (40) as a pump chamber. The use of a bellow (40) as the air chamber in an air/liquid pump mechanism allows the pressure/volume profile of the air supply to be tailored to supply the desired air/liquid ratio throughout the travel of the pump mechanism. The shape of the air bellow (40) is preferably selected to provide an initially large volume reduction in the air chamber (80) as the bellow (40) collapses to provide a rapid rise in air pressure available for dispensing. In a preferred embodiment, dual bellows (40, 45) are utilized (one for liquid (45), one for air (40)) in a concentric arrangement to allow the pressure/volume profile for each to be tailored to achieve the desired spray or foam characteristics. Inlet and outlet valves unitarily formed with the liquid bellows are disclosed, as is the use of a pre-compression mechanism for the liquid outlet valve to allow the air pressure to build to the level required for satisfactory performance before the liquid begins to flow.

Abstract: Ä ~ tous les jours des milliers de travailleurs de la construction utilisent des échafaudages pour effectuer du travail en hauteur. Le menuisier qui utilise un sac à outils aura la possibilité d'avoir à portée de la main ses outils en les ayant accrochés sa taille. Cependant les ouvriers qui utilisent des chaudiéres comme les peintres, les plâtriers, les maçons, les laveurs de vitres ou de revêtements extérieurs, ceux qui posent du crépis, et tous les travailleurs en hauteurs n'ont rien pour supporter leurs récipients ou les outils spéciaux qu'ils doivent utiliser. Ils doivent ou déplacer leurs récipients, ou les contourner s'ils veulent éviter de s'y barrer les pieds et chaque fois la manoeuvre peut comporter un risque autant pour eux que pour les personnes pouvant se trouver en dessous.. Dans la présente invention non seulement le travailleur n'a-t-il plus à porter, déplacer, ou contourner son récipient, mais il n'aura plus à se plier pour y avoir accès éliminant ainsi les fatigues lombaires ou autres. Il pourra de plus y accrocher de façon sécuritaire tous ses outils spécialisés quand il aura fini de les utiliser, évitant ainsi de s'y barrer les pieds.

Title: Method and apparatus for power lysis of a thrombus
Inventor: CRAGG ANDREW H
IPC: A61M31/00
Filed: 1998-05-19
Abstract: Thrombectomy methods and apparatus for removing a thrombus from a blood vessel involving high velocity injection of a thrombolytic agent, e.g., a plasminogen activator, through multiple, closely spaced, side wall infusion holes in a high strength catheter distal end infusion segment to lyse the adjacent thrombin. The infusion catheter is formed with a catheter lumen extending from a proximal end connector assembly to a distal end valve that is normally closed but is penetrable to allow introduction of a guidewire through the catheter lumen and distal end valve and to thereby allow advancement of the infusion catheter over the guidewire, thereby allowing access of the distal infusion segment to a wide number of locations. The infusion holes extend from the catheter lumen through the catheter side wall. Thrombolytic agent is pumped in a pulsatile manner through the catheter lumen under high pressure after removal of the guidewire and closure of the distal end valve. High velocity, short duration, power lysis jets are emitted through the closely spaced, small diameter infusionholes and finely lyse the thrombin without the need to withdraw blood and fibrin. The infusion segment is preferably moved back and forth as the power lysis jets of thrombolytic agent are emitted. The catheter infusion segment is moved to orient the infusion segment with successive sections of the thrombus, and the high velocity lysing is repeated as necessary.

Title: Radioisotope stent with increased radiation field strength at the ends of the stent
Inventor: FISCHELL DAVID R
IPC: A61F2/82
Filed: 1998-06-26
Abstract: Disclosed is a radioisotope stent that has increased radioactivity at the end regions of the stent as compared to the stent's central region. To minimize the neointimal hyperplasia that may exist to a greater extent at the ends of a stent that is implanted into an artery of a human body, the amount of radioactivity placed at or near the ends of the stent should be increased as compared to the amount of radioactivity over the remainder of the stent. It is an additional object of this invention to increase the radiation field at the end of a radioisotope stent by placing additional metal surfaces at the ends of the stent so as to have additional surfaces onto which a radioisotope can be placed.

Patent CA-2243863-A1 (CA)
Title: Gastrointestinal drug delivery system
Inventor: PENHASI ADEL
IPC: A61K9/16
Filed: 1997-01-17
Abstract: A gastrointestinal delivery system is provided. The system comprises a drug in combination with a core material, the core being surrounded by a water-insoluble or relatively water-insoluble coating material in which particulate water-insoluble material is embedded. When the delivery device enters the gastrointestinal tract, the particulate matter takes up liquid, thus forming channels interconnecting the drug-containing core with the outside of the delivery device. These channels allow the release of drug from the core into the gastrointestinal tract. By controlling parameters in the device, such as the core material, carrier material in the coating, and particulate matter, the location of release of the drug can be carefully controlled. Thus, the invention is also directed to a method of using the device for the treatment of disease by the release of drugs in the gastrointestinal tract in a location-and time-dependent manner.
