| 20090292350 | Stents for Prosthetic Heart Valves - A stented valve including a stent structure including a generally tubular body portion having a first end, a second end, an interior area, a longitudinal axis, and a plurality of vertical wires extending generally parallel to the longitudinal axis around a periphery of the body portion, wherein the plurality of vertical wires includes multiple commissure wires and at least one structural wire positioned between adjacent commissure wires, and a plurality of V-shaped wire structures having a first end, a second end, and a peak between the first and second ends, wherein a first end of each V-shaped structure extends from a first vertical wire and a second end of each V-shaped structure extends from a second vertical wire that is adjacent to the first vertical wire, wherein each V-shaped structure is oriented so that its peak is facing in the same direction relative to the first and second ends of the body portion, and a valve structure including a plurality of leaflets attached to the stent structure within the tubular body portion. | 11-26-2009 |
| 20100011564 | PROSTHETIC HEART VALVE, PROSTHETIC HEART VALVE ASSEMBLY AND METHOD FOR MAKING SAME - A mold assembly for forming a prosthetic valve having at least one leaflet, which includes a first plate having a first side from which at least one leaflet mold extends and a planar portion adjacent the at least one leaflet mold, wherein the planar portion has multiple access holes through its thickness, and a second plate having at least one mold opening and a planar portion adjacent the at least one mold opening, wherein each mold opening is sized and shaped to correspond with one of the leaflet molds of the first plate, and wherein the planar portion has multiple access holes through its thickness. The second plate is positionable relative to the first plate so that each of the leaflet molds of the first plate extend at least partially through one of the mold openings of the second plate. | 01-21-2010 |
| 20100018447 | METHODS AND APPARATUSES FOR ASSEMBLY OF A PERICARDIAL PROSTHETIC HEART VALVE - A method of assembling a prosthetic valve using sheets of material, such as pericardium material, polymer or bioengineered film, or other material. The method provides an accurate and repeatable system of making pericardial valves in which sheets or pieces of material are held securely in place relative to each other throughout the steps of assembling the valve. In addition, methods of the present invention include maintaining consistent alignment of the fixtures and pericardium material throughout the valve assembly process and utilize features that make the tooling components easy to assemble and handle. Certain aspects of the invention can be used to help establish a repeatable sewing and cutting technique for creating a pattern shape for valve leaflets, establishing stitch lengths, and determining the exact placement of stitches. | 01-28-2010 |
| 20100023120 | TISSUE ATTACHMENT DEVICES AND METHODS FOR PROSTHETIC HEART VALVES - A multi-leaflet valve, which includes at least two leaflets, an outer tube, and a seam protector for each seam. Each seam protector is positioned to be in contact with a portion of the outer tube, with tube portions and leaflet ends being positioned between adjacent seam protection pieces. The seam protectors provide a lower stress surface about which the leaflets can bend or flex during their opening and closing. The seam protectors may include an enlarged end portion with an extending straight surface, an inverted U-shaped structure, or a sinusoidal-shaped structure, for example. The valve can further be provided with a seam cover or protector that is stitched onto the seam allowance of the layers of one or more of the seams. The seams can be provided with one or more inserts to fill spaces between adjacent tissue layers and create tension in certain material sheets. | 01-28-2010 |

| 20080237377 | Feed roller drive for wood chipper - The present disclosure relates to a wood chipper that has a feed roller driven by a hydraulic motor. Hydraulic fluid under pressure is provided to the motor through a two-stage pump, providing separate flows of fluid under pressure. The flows of the pump stages are combined for normal operation of the chipper. A bypass that will bypass the flow from one pump stage when the pressure of the fluid under pressure driving the motor exceeds a pre-selected level from increased load on the feed roller is provided. When the bypass is open the feed roller is slowed to reduce the feed rate of material into the chipper, and when the feed roller loads reduce, the flows will again be combined to speed up the feed roller. | 10-02-2008 |
| 20100024919 | Log splittter - A log splitter having a bed for accepting a log. The bed has an operating length between first and second components, with the former a wedge. The log splitter can be placed in: (a) a first operative state wherein the bed has a first operating length; and (b) a second operative state wherein the bed has a second operating length. With the log splitter in the first operative state, the wedge is movable: (a) from a first starting position in a first lengthwise direction to effect splitting of a log; and (b) thereafter, oppositely to the first lengthwise direction back into the first starting position. In the second operative state, the wedge is movable: (a) from a second starting position to effect splitting; and (b) thereafter, back into the second starting position. The log splitter further has an operating assembly to move the first component. | 02-04-2010 |
| 20110024139 | WINDROWER AND METHOD OF WINDROWING A GROWN PRODUCT - A windrower with a frame that: a) has a front, a rear and laterally spaced sides; and b) is movable in an advancing direction. A processing mechanism is capable of: a) unearthing grown product; and b) separating foreign matter from the grown product as the frame is advanced. A cross conveyor assembly controllably discharges grown product from the processing mechanism to the underlying terrain. The cross conveyor assembly has a first discharge end and at least one section, including the first discharge end, that is selectively translatable laterally relative to the frame as the frame is advancing thereby to laterally change a location of the first discharge end and thus the lateral discharge location for the cross conveyor assembly at the first discharge end. | 02-03-2011 |
| 20110036651 | PTO DRIVEN HYDRAULIC SYSTEM - A hydraulic system operably coupled to a vehicle, the vehicle having at least one PTO drive and having a hydraulic system for, in part, cooling hydraulic fluid, includes a closed hydraulic circuit having at least a first and a second hydraulic loop, a pump being a component of each of the at least a first and a second hydraulic loops, the pump being operably, rotatably coupled to the PTO drive, the first hydraulic loop having a feed line fluidly coupled to the vehicle hydraulic system and to the pump and a return line in fluid communication with the pump and operably, fluidly coupled to the vehicle hydraulic system; and the second hydraulic loop having a pressure line fluidly coupled to a output of the pump and a return line fluidly coupled to a pump return inlet, the second hydraulic loop being fluidly couplable to an implement for providing hydraulic power thereto. A method of forming the hydraulic system is included. | 02-17-2011 |
