20090250020 | Reciprocating combustion engine - Methods and apparatus are described for a reciprocating combustion engine. A method includes operating a dual-piston engine including introducing a gas into a pair of combustion chambers; introducing a fuel into the pair of combustion chambers; compressing the gas; combusting the gas and the fuel; and exhausting combusted gases. Each of the pistons drives a reciprocating crankshaft that protrudes through a cylinder wall and cooperatively rotate a pair of rotors by engaging substantially sinusoidal cam tracks on the rotors. An apparatus includes a cam driven, concentric drive rotary-valve dual-piston engine. | 10-08-2009 |
20120138702 | Pressure compensated fuel injector - A method of operating a pressure compensated fuel injector includes: filling a fuel chamber with a charge of fuel by closing an injector valve and circulating a fuel from a fuel source through a plurality of recirculating valves and a cap valve; then isolating the fuel chamber and the charge of fuel from the fuel source; then equalizing a pressure within the fuel chamber to a rising pressure outside the fuel chamber by reducing a volume of the isolated fuel chamber; and then activating a solenoid that is coupled to the injector valve, opening the injector valve; and then further reducing the volume of the isolated fuel chamber to apply an over pressure within the chamber, pumping fuel from the fuel chamber through the injection orifice. | 06-07-2012 |

20080249604 | APPARATUS AND METHOD FOR MEDICAL PROCEDURES WITHIN A SPINE - Devices and methods for performing a procedure within a spine are disclosed herein. In one embodiment, a method includes inserting an expandable member into an interior of a bone-related structure. The expandable member defines a first and second lumen. A medium is delivered through the first lumen and into the interior of the expandable member while within the interior of the bone-related structure. A filler material is delivered through the second lumen and into a cavity within the interior of the bone-related structure while the expandable member is disposed therein. An apparatus can include an expandable member that defines a first lumen in fluid communication with an interior volume of the expandable member, and a second lumen in fluid communication with an opening of the expandable member. The second lumen is configured to communicate a filler material through the opening and into an interior cavity of a bone-related structure. | 10-09-2008 |
20130289571 | CEMENT DELIVERING DEVICE AND METHOD - A delivery system includes a reservoir for storing pressurized fluid and a piston rod passing through the reservoir and having an end portion with a dimension larger than the piston rod. A sleeve is configured to engage the end portion of the piston rod such that when the piston rod is advanced, the end portion seals an opening in the sleeve. The sleeve and the end portion function as a piston for extracting fluid from a delivery chamber. When the piston rod is retracted, the sleeve engages a portion of the end portion to permit the reservoir to communicate with the delivery chamber through the opening. Methods of use are disclosed. | 10-31-2013 |
20130289725 | System and Device for Providing Nutrition to Intervertebral Tissue and Method of Use - A bone implant device includes a barrel having a sharpened distal end for advancing into bone and a proximal end portion configured to engage a driver end for advancing and turning the barrel to implant the barrel into bone. A channel is formed longitudinally through at least a portion of the barrel and is open ended on the proximal end portion. A permeable material is disposed within the channel that permits fluid communication therethrough between the distal end and the channel. Methods of use are disclosed. | 10-31-2013 |
20140190569 | VALVE CONTROL MECHANISM AND METHOD - A valve controller includes a housing, and a lever extending from the housing. The lever includes a protrusion rigidly attached to the lever, and the lever is biased to an initial position. A switch has an open and a closed position. A linkage is pivotally connected to the switch, and the linkage includes a centrally disposed slot configured to receive the protrusion such that movement of the switch controls movement of the linkage and the lever such that moving the switch to the closed position closes a valve controlled by the lever regardless of a position of the lever. | 07-10-2014 |
20140242630 | Laser Microdissection Method and Apparatus - Systems and methods for automated laser microdissection are disclosed. In one variation, targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition to the location of an interior of a cut path. In another variation, a sample of biological material is mounted onto a polymer membrane which is then placed onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the biological material. In yet another variation, a sample of biological material is mounted onto a polymer membrane which is then inverted onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the polymer membrane. Then, an UV laser cuts along a cut path around the targeted portions of biological material in a closed cut path or a substantially closed cut path defining an interior and an exterior portion of the tissue sample. In a substantially closed cut path, bridges are left spanning the interior of the cut path and the exterior of the cut path. An IR laser activates at least a portion of the transfer film such that the transfer film in the vicinity of targeted portion adheres to the biological material interior to the cut path. The transfer film is then removed separating the targeted portions of biological material which are adhered to the transfer film from the remaining portion of the tissue sample. | 08-28-2014 |
