| 20110066184 | ARTICULATING SUTURING DEVICE AND METHOD - Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract. | 03-17-2011 |

The bit crown has blades over a face portion thereof, the blades including a plurality of cutting elements attached thereto. The bit crown further includes a composite inlay positioned at least within the substantially hollow interior. Casing bits also include case hardened outer surfaces radially outside the drill-out region. Casing bits further include short-substrate cutting elements. Methods of forming a casing bit are also disclosed. | 05-14-2009 |
| 20090217597 | ABRASIVE-IMPREGNATED CUTTING STRUCTURE HAVING ANISOTROPIC WEAR RESISTANCE AND DRAG BIT INCLUDING SAME - An abrasive-impregnated cutting structure for use in drilling a subterranean formation is disclosed. The abrasive-impregnated cutting structure may comprise a plurality of abrasive particles dispersed within a substantially continuous matrix, wherein the abrasive-impregnated cutting structure exhibits an anisotropic wear resistance. One or more of the amount, average size, composition, properties, shape, quality, strength, and concentration of the abrasive particles may vary within the abrasive-impregnated cutting structure. Anisotropic wear resistance may relate to a selected direction, such as, for example, one or more of an expected direction of engagement of the abrasive-impregnated cutting structure with the subterranean formation and an anticipated wear direction. Anisotropic wear resistance of an abrasive-impregnated cutting structure may be configured for forming or retaining a formation-engaging leading edge thereof. A rotary drag bit including at least one abrasive-impregnated cutting structure is disclosed. | 09-03-2009 |
| 20090272582 | MODULAR HYBRID DRILL BIT - An earth-boring bit comprising a bit body is cofigured at its upper end for connection into a drillstring. A fixed blade depends axially downwardly from the bit body. An axially extending slot is formed in the bit body adjacent the fixed blade. A bit leg is received and retained in the slot by engagement between the slot and correspondingly shaped bit leg, wherein the bit leg cannot be removed from the slot except by axial movement relative to the bit body. A rolling cutter is secured to the bit leg at its lower extent. A fastener secures the bit leg against movement relative to the bit body and extends through oblong apertures in the bit leg and into the bit body, wherein the bit leg can be moved axially relative to the bit body to adjust the projection of the rolling cutter relative to the fixed blade. The slot defines a pair of generally opposed sides connected by a third side, the generally opposed sides being inclined toward one another to define a dovetail that corresponds with the shape of the bit leg. The bit body further comprises a shank that is configured for connection into the drillstring at its upper extent and has a generally cylindrical receptacle formed in its lower extent; and a bit body portion having a generally cylindrical upper extent, the receptacle being and dimensioned to receive the upper extent of the bit body, wherein the shank and bit body portions are secured together by welding. | 11-05-2009 |

| 20100230942 | Solid propellant/liquid type hybrid gas generator - A gas generator comprising a housing having a mixing chamber and a pyrotechnic charge in the housing. A container having a liquid therein is disposed in the housing and has an open end and a closed end, with an end cap closing the open end and having a piston portion removably connected thereto and being movable within the liquid container to pressurize the liquid therein when the piston portion is separated from the end cap. The piston portion is positioned to be exposed to combustion gas from the pyrotechnic charge when it is ignited and is separable from the end cap when the combustion gas exceeds a predetermined pressure. In another embodiment, the liquid container may be a collapsible tube. The closed end of the liquid container has a weakened portion constructed to be opened when the pressure of the liquid in the container exceeds a predetermined pressure. The pyrotechnic charge and the weakened portion of the liquid container are in fluid communication with the mixing chamber so that combustion gases from the ignition of the pyrotechnic charge mix with and vaporize the liquid in the mixing chamber to generate a non-toxic, low temperature, low particulate inflation gas. | 09-16-2010 |
