Surgical Stapling Device for Performing Circular Anastomoses

The present disclosure is directed to a surgical stapling device (10) for performing circular anastomoses. The surgical stapling device includes a handle portion (12), an elongated body portion (14) and a head portion (16) including an anvil assembly (30) and a shell assembly (31). The handle portion (12) includes a rotatable approximation knob (22) for approximating the anvil and shell assemblies (30,31) and a firing trigger (20) for actuating a firing mechanism for ejecting staples positioned within the shell assembly (31). The firing trigger (20) forms one link of a two bar linkage provided to actuate the firing mechanism. The anvil assembly (30) includes a tiltable anvil which will tilt automatically after firing of the device and unapproximating the anvil and shell assemblies (30,31). The head portion (16) also includes a retractable trocar assembly (240) which is slidably positioned within an anvil retainer (38) and is automatically advanced and retracted upon attachment and detachment of the anvil assembly (30) onto the anvil retainer (38). A lockout tube (270) is provided and is positioned about the anvil retainer (38) for releasably engaging an anvil assembly (30). The lockout tube (270) prevents inadvertent detachment of the anvil assembly (30) from the anvil retainer (38). The surgical stapling device (10) also includes a firing lockout assembly which prevents actuation of the firing trigger (20) until an anvil has been attached to the device and the anvil (129) has been approximated. A tactile indication mechanism is also provided for notifying a surgeon that the device has been fired and for notifying a surgeon that the anvil head has been unapproximated a distance sufficient to permit the anvil head to tilt.

Wirelessly-chargeable heating pad

InactiveUS20110220634A1Improve flexibility and convenienceEasy repairing and maintenancePillowsBlanketElectric energyElectricity
The present invention provides a wirelessly-chargeable heating pad, which is coupled to an article in a removable manner and is used in combination with a charging device to perform wireless electrical charging. The wirelessly-chargeable heating pad includes a receiver circuit, a heating element, and a pad body. The receiver circuit includes a rechargeable battery. The heating element is electrically connected to the rechargeable battery. The heating element and the receiver circuit are both mounted to the pad body. The article includes a removable mounting structure, so that the wirelessly-chargeable heating pad is removably coupled to the article through the removable mounting structure. The charging device, after receiving electrical power, converts the electrical power into an alternate current signal that is transmitted to the receiver circuit. The receiver circuit receives and converts the alternate current signal into electrical power that is then stored in the rechargeable battery. The rechargeable battery subsequently supplies the electrical power to the heating element to give off heat.

Enhanced capacity and purification of antibodies by mixed mode chromatography in the presence of aqueous-soluble nonionic organic polymers

ActiveUS20080177048A1High level of productivityEnhance binding capacityComponent separationSolid sorbent liquid separationChemistryWater soluble
This invention relates to the use of mixed mode chromatography for purification of at least one intact non-aggregated antibody from a mixture containing intact non-aggregated antibodies and undesirable materials, including fragmented or aggregated antibodies, host cell proteins, DNA, endotoxin, and / or virus. This invention further relates to the integration of such a method into a multi-step procedure with other fractionation methods for purification of antibodies suitable for in vivo applications.

Debulking catheters and methods

InactiveUS20050177068A1Enhance removalImprove material and shapeVaccination/ovulation diagnosticsExcision instrumentsDistal portionDebulking tumor
A debulking catheter comprising a tissue debulking assembly for removing a contiguous strand of material from a body lumen. Catheters of the present invention generally include a catheter body having proximal and distal portions and a tissue debulking assembly disposed at least partially within the distal portion. The tissue debulking assembly is radially movable to expose at least a portion of the assembly through a window on the catheter body. The catheter is advanced transluminally through the body lumen to contact material in the body lumen and remove a plane of contiguous material that has a length that is typically longer than a length of the window on the catheter. The contiguous material may be directed into a collection chamber. Thereafter, the material may be removed from the collection chamber and preserved or tested.

In-sewer treatment of wastewater and sludges

A method and apparatus for in-sewer wastewater treatment comprising steps of largely spontaneously growing acidogenic bacteria in sewer lines and providing methanogenic bacteria in these lines. Methanogenic bacteria can be grown using wastewater, solid, or other waste, or other organic feedstock as a substrate. Methanogenic bacteria can be cultivated at a wastewater treatment plant or at other locations in special reactors, or provided from anaerobic wastewater pretreatment plants. Digestion gases can be either vented out or collected and used.

Methods, apparatus and systems for generating digital-media-enhanced searchable electronic records of underground facility located and/or marking operations

Generating a digital-media-enhanced electronic record of a locate and / or marking operation performed by a locate technician. The locate and / or marking operation comprises locating and / or identifying, using at least one physical locate mark, a presence or an absence of at least one underground facility within a dig area, wherein at least a portion of the dig area may be excavated or disturbed during excavation activities. A location of the at least one underground facility and / or the at least one physical locate mark is electronically rendered on a display device so as to generate an electronic visual representation of the locate and / or marking operation. At least one digital media file representation of a corresponding digital media file relating to at least one aspect of the locate and / or marking operation or an environment of the dig area is also electronically rendered on the display device, so as to generate a digital-media-annotated representation of the locate and / or marking operation. Information relating to the digital-media-annotated representation of the locate and / or marking operation is electronically transmitted and / or stored so as to generate the digital-media-enhanced electronic record of the locate and / or marking operation.
