Appl. No.:

11/251328

Vahe Yacoubian - Glendale CA, US
Mehmet Bicakci - Santa Ana CA, US
Michael Webb - Mission Viejo CA, US

International Classification:

A61M 31/00
A61M 37/00

US Classification:

604093010

Abstract:

A vent cannula includes a tubular base having a primary longitudinal passage therein with a primary distal tip for insertion into a body vessel. The base has a tubular junction interconnected and extending at an acute angle having a secondary passage therein communicating with the primary passage. A flexible tube is slidably retained within the secondary passage. The flexible tube has a flexible distal portion with a flexible distal tip thereon, a flexible proximal portion with a side port therein and with a proximal handle. The flexible tube is initially positioned at a “first position” wherein the flexible distal tip is within the secondary passage; and is slideable to a “second position” wherein the side port of the flexible proximal portion is at the junction of the primary and secondary passages, and the flexible distal tip is inserted into the primary passage and extended from the primary distal tip to thereby extend the functional tip of the cannula. In a first embodiment, the proximal portion of the flexible tube is sealed within the base by a flexible sleeve; and in a second embodiment, the flexible tube is sealed with elastomeric washers retained between the base and an end cap.

Abstract:

Electrolyte solutions including at least one anhydrous fluoride salt and at least one non-aqueous solvent are presented. The fluoride salt includes an organic cation having a charge center (e.g., N, P, S, or O) that does not possess a carbon in the β-position or does not possess a carbon in the β-position having a bound hydrogen. This salt structure facilitates its ability to be made anhydrous without decomposition. Example anhydrous fluoride salts include (2,2-dimethylpropyl)trimethylammonium fluoride and bis(2,2-dimethylpropyl)dimethylammonium fluoride. Combining these fluoride salts with at least one fluorine-containing non-aqueous solvent (e.g., bis(2,2,2-trifluoroethyl)ether; (BTFE)) promotes solubility of the salt within the non-aqueous solvents. The solvent may be a mixture of at least one non-aqueous, fluorine-containing solvent and at least one other non-aqueous, fluorine or non-fluorine containing solvent (e.g., BTFE and propionitrile or dimethoxyethane). The electrolyte solutions may be employed in electrochemical cells, such as batteries, fuel cells, electrolysis systems, and capacitors.

Abstract:

Processes and reaction mixtures including non-aqueous solvent mixtures are presented. Non-aqueous solvent mixtures including fluoride salt and non-aqueous solvent combinations are provided that possess high fluoride ion concentrations useful for a range of applications, including organic synthesis. Further non-aqueous solvent mixtures are provided including a salt possessing a non-fluoride anion and a non-aqueous solvent that, when contacted with aqueous fluoride-containing reagents, extract fluoride ions to form non-aqueous fluoride-ion solutions possessing high fluoride-ion concentrations. The salts include an organic cation that does not possess a carbon in the β-position or does not possess a carbon in the β-position having a bound hydrogen. This salt structure facilitates its ability to be made anhydrous without decomposition. Example anhydrous fluoride salts include (2,2-dimethylpropyl)trimethylammonium fluoride and bis(2,2-dimethylpropyl)dimethylammonium fluoride. The combination of these fluoride salts with at least one fluorine-containing non-aqueous solvent (e.g., bis(2,2,2-trifluoroethyl)ether; (BTFE)) promotes solubility of the salt within the non-aqueous solvents.
