International Classification:

A61N 1/375

US Classification:

607 37

Abstract:

A feedthrough terminal assembly for an active implantable medical device (AIMD) includes a conductive terminal pin or lead wire which extends through a conductive ground plane of the AIMD in non-conductive relation. A feedthrough capacitor associated with the terminal pin or lead wire has first and second sets of electrode plates coupled, respectively, to the conductive pin or lead wire and to the ground plane. A breathable electromechanical connection material conductively couples the capacitor's electrode plates to respective components of the AIMD, which allows helium gas to pass freely therethrough during a standard pressurized or vacuum pull helium leak detection test. A breathable washer may be disposed between an alumina insulator and a surface of the capacitor. An additional further breathable coating or conformal coating may be placed over a surface of the feedthrough capacitor disposed toward the interior of the AIMD.

US Classification:

514 56, 435 15

Abstract:

The disclosure provides in vitro and in vivo methods for identifying Heparins and Heparinoids that modulate the activity of selectins. The disclosure also provides Heparins and Heparinoids that modulate the activity of selectins. The identification and isolation of these heparin formulations has the potential to mediate a wide variety of pathologies mediated by P- and/or L-selectin, including hematogenous metastasis, diseases associated with inflammation (e.g., asthma, arthritis, allergic dermatitis), ischemia-reperfusion injury, or other pathologies such as sickle cell anemia. Selectin inhibition can be achieved at plasma concentrations lower than those that cause excessive anticoagulation or unwanted bleeding in a human subject.

International Classification:

B01F 23/2361
B01F 33/501

Abstract:

A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has a rounded shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the rounded shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

Abstract:

A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has an oblate spheroid shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the oblate spheroidal shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

International Classification:

B01F 3/04
B01F 13/00

Abstract:

An expansion chamber includes a chamber body having a top portion above a bottom portion cooperatively forming a hollow chamber volume configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, including wine and other alcoholic beverages. The bottom portion has a bottom opening configured to engage an opening of an uncorked and/or opened wine bottle. The top portion has a top opening. The hollow chamber volume is configured to be in fluid communication with an inside of the uncorked and/or opened bottle when the bottom opening is engaged with the opening of the uncorked and/or opened bottle. A maximum inside diameter of the hollow chamber volume in a horizontal plane with respect to the uncorked and/or opened wine bottle set upon a horizontal surface is cooperatively formed between the top and bottom portions, wherein the maximum inside diameter is at least 2.50 inches.

B01F 15/06
B01F 15/00

Abstract:

An aeration assembly for aerating liquids including wine and other alcoholic beverages includes an expansion chamber and an aerating device. The expansion chamber is configured to be in fluid communication with an inside of the uncorked and/or opened bottle when engaged by a bottom portion of the expansion chamber. The aerating device comprises a gas conduit having a proximal end in fluid communication with a distal end. The distal end is disposable below the bottom portion of the expansion chamber. A gas source is in fluid communication with the proximal end of the gas conduit. The expansion chamber is configured to temporarily contain an expansion of bubbles during an aeration process. The expansion chamber and aerating device are not permanently connected, wherein the aerating device can be fully removed from the expansion chamber before, during or after the aeration process.

International Classification:

B01F 15/00
C12G 1/00
B01F 15/02

Abstract:

A wine aerator includes a seal configured to engage an opening of an uncorked wine bottle. A gas conduit passes through the seal and is configured to be attachable to a gas source supplying air and/or oxygen inside the uncorked wine bottle thereby aerating the wine. A bubble-generating aeration element is disposed at the gas conduit distal end. A bubble-reducing filter element is in fluidic communication with the inside and outside of the uncorked wine bottle through the seal, wherein the bubble-reducing filter element is disposed at, near and/or within the seal. When the seal is engaged with the opening of the uncorked wine bottle the bubble-reducing filter element separates the inside from the outside of the uncorked wine bottle. The bubble-reducing filter element helps to reduce the amount of bubbles that are being generated from the wine aerator during the aeration process.
