Abstract: A pressure control system for controlling pressure of a fluid in a chamber includes a pressure sensor configured to measure the pressure of the fluid in the chamber, and a valve configured to control the pressure of the fluid in the chamber by regulating flow of the fluid from the chamber. The pressure control system further includes a controller. The controller is configured to estimate the volume of the chamber, and to generate a pump speed curve of the valve. The controller is further configured to monitor and modify the pump speed curve so as to maintain a slope of the pump speed curve to at least a minimum value, and to use the modified pump speed curve to adjust the position of the valve in response to pressure measurements by the pressure sensor, so as to maintain the pressure in the chamber at a desired pressure setpoint.

Abstract: An endovascular graft adapter for use in abdominal aortic aneurysms comprising a graft adapter body defining an upper graft adapter section member and a lower graft adapter section member. The upper and lower graft adapter section members respectively have a pair of cut-out sections formed through sidewalls thereof and both pairs of cut-out sections are respectively aligned with the right and left renal arteries. The upper graft adapter section member has an upper axially directed through passage extending from a proximal end to a distal end thereof and the lower graft adapter section member has a lower axially directed through passage extending from a proximal end to a distal end thereof. The upper and lower axially directed through passages are in alignment each with respect to the other.

Abstract: Cellulose mixed esters are disclosed having low molecular weights and low degrees of polymerization. These new cellulose mixed esters include cellulose acetate propionate and cellulose acetate butyrate. The esters exhibit solubility in a wide range of organic solvents with minimal viscosity increase, are compatible with a wide variety of resins, and are useful in coatings and inks compositions as binder resins and rheology modifiers.

Abstract: A hand held motor powered device for percutaneous thrombolysis and evacuation of a clot from a clotted arterio-venous fistula is disclosed. The percutaneous thrombectomy device is provided with a plurality of nested coaxial lubricious catheters. The multi-functional thrombectomy device can simultaneously and sequentially degrade and evacuate a blood clot from a blood vessel by multiple modalities that combines to degrade the clot by mechanical agitation, fragmentation and disruption, by peri-thrombus delivery of enzymatic fluids, by irrigation with biocompatible fluids, and by balloon displacement. The thrombectomy device further provides for balloon containment and isolation of clot debris from the general circulation, thereby minimizing the risks to a patient of embolic sequelae. There is also provided an optional steering mechanism for controlled deflection of the working end of the device.

Abstract: Valve assemblies are disclosed including a housing having a flow channel and an annular surface surrounding the flow channel, a slide plate movable to a closed position, and a seal ring positioned between the annular surface and the slide plate. The seal ring can include first and second sides, a first surface extending between the sides and facing towards the annular surface of the housing, and a second surface axially spaced from the first surface and extending between the first and the second sides and facing towards the slide plate. The second surface can include a continuous annular sealing portion for contacting the slide plate when the seal ring is biased against the slide plate so that a fluid-tight seal can be formed between the continuous annular sealing portion and the slide plate, and at least one passageway positioned between the annular sealing portion and the second side.

Abstract: A valve assembly including a housing having a flow path extending to an outlet and a valve seat in the flow path and around the outlet, a slide plate located in the housing and movable transversely to a longitudinal axis of the flow path between a closed position, in which the slide plate is in contact with the valve seat and blocks flow through the flow path, and an opened position, in which the slide plate allows flow through the flow path, and wherein at least one of the slide plate and the valve seat includes at least one passageway for providing a predetermined amount of conductance between the slide plate and the valve seat when the slide plate is in the closed position.

Abstract: A method of printer/copier obtaining information from printer/copier printing media is provided. The method includes placing the printing media in the printer/copier, the printer/copier sensing for identifying markings on the printing media identifying the printing media as the appropriate printing media for the printer/copier, the printer/copier determining if the printing media is the appropriate printing media for use in the printer/copier. A printer/copier system for obtaining information from printing media for use in a printer/copier is provided. The printer/copier system includes a sensor for sensing for identifying markings on the printing media identifying the printing media as the appropriate printing media for the printer/copier, and a controller for determining if the printing media is the appropriate printing media for the printer/copier.

Abstract: Particles of an amino acid such as leucine may be formed from an amino acid vapor, for example by aerosol condensation, or by spray drying. The amino acid particles have a bulk density of not more than 0.1 gcm?3 or have a mass median aerodynamic diameter of not more than 10 ?m or are in the form of flakes having a thickness of not more than 100 ?m. The inclusion of the particles of amino acid in powder for use in dry powder inhalers has been found to improve the respirable fraction of the active material in the powder.

Abstract: The invention provides systems and methods for implementation of a computer language type system by augmenting finite state automata algorithms to accommodate symbols having both subtype relationships and nested types. To make the classical automata algorithms work for type system with subtypes, finite state automata for a data type is augmented by additional transitions that include secondary symbols, wherein secondary symbols are subtypes of symbols of alphabet of finite state automata. A data type when compared to another data type must compare both names and the contents.

Abstract: The present invention relates to pluripotent stem cells, particularly to pluripotent embryonic-like stem cells. The invention further relates to methods of purifying pluripotent embryonic-like stem cells and to compositions, cultures and clones thereof. The present invention also relates to a method of transplanting the pluripotent stem cells of the present invention in a mammalian host, such as human, comprising introducing the stem cells, into the host. The invention further relates to methods of in vivo administration of a protein or gene of interest comprising transfecting a pluripotent stem cell with a construct comprising DNA which encodes a protein of interest and then introducing the stem cell into the host where the protein or gene of interest is expressed. The present also relates to methods of producing mesodermal, endodermal or ectodermal lineage-committed cells by culturing or transplantation of the pluripotent stem cells of the present invention.

Abstract: Systems and methods in accordance with the present invention provide for an implementation of the XQuery standard, and such an implementation will be referred to herein as an XQuery (XML Query language) implementation. An XQuery implementation can be based on a token stream representation, which allows large XML documents to be processed without having to first read the entire document. An XQuery implementation can also utilize a streaming XQuery engine. A set of algorithms and a set of rewrite rules can be used for the implementation. Given a query, a set of rules can be applied to that query to transform the query into another query. Some of these rules allow the resulting query to be streamable. In other words, a query that would otherwise require an XML document to be read into memory can now be transformed into a query that can work on an XML stream. The type system of the XQuery language can be based on XML Schema, and the basic types of XML Schema can have derived types.
