| 20090286008 | Laser-produced porous surface - A method of fabricating a porous or partially porous three-dimensional metal article for use as a tissue ingrowth surface on a prosthesis. The porous article is formed using direct laser remelting in a cross section of a layer of metallic powder on a build platform without fusing thereto. The power, speed, spot size and beam overlap of the scanning laser is coordinated so that a predetermined porosity of the metallic powder can be achieved. Laser factors also vary depending from the thickness of the powder layer, type of metallic powder and size and size distribution of the powder particles. Successive depositing and remelting of individual layers are repeated until the article is fully formed by a layer-by-layer fashion. In an additional embodiment, a first layer of metallic powder may be deposited on a solid base or core and fused thereto. | 11-19-2009 |
| 20100010638 | Laser-Produced Porous Surface - An implant having a porous tissue ingrowth structure and a bearing support structure is disclosed. The implant includes a metal insert having a bone ingrowth structure, an intermediate structure and a bearing support structure. A bearing surface is formed from a polymer material and attached to the bearing support structure. The intermediate structure has a porosity sufficient to inhibit the polymer material from translating through the bearing support structure to the bone ingrowth structure. | 01-14-2010 |

| 20110014081 | LASER-PRODUCED POROUS STRUCTURE - The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant. | 01-20-2011 |

| 20100300746 | ENCAPSULATION PROCESS AND STRUCTURE FOR ELECTRONIC DEVICES - Electronic devices, such as photovoltaic, transistor or doped light-emitting devices, can be manufactured with an air-based manufacturing process and device structure that encapsulates the device with air-stable electrodes and active layers that are reasonably stable in their unexcited state. A sheet of flexible material may act as a substrate and a second sheet of material acts as a cover. Getter materials are included in the encapsulated device, with the getter latent or unreactive during the manufacturing process. | 12-02-2010 |

| 20090106943 | REMOVABLE POWER TOOL PIVOTING ARM BRACE - The subject of this disclosure is a brace for a variety of power tools to assist a user in controlling the tool. The brace extends from the power tool, and engages the forearm of the user to offset the pivot moment about the users wrist due to the weight and length of the power tool. The brace is configured to pivot in the horizontal and/or vertical plane to increase the ease of use and comfort of the user and/or to reduce the length of the overall tool and brace for storage. | 04-30-2009 |

| 20110213360 | Tensioning Mechanism for Articulation Drive Cables - A surgical instrument includes a housing, an elongated shaft extending distally from the housing, and an end effector extending distally from the elongated shaft. A tensile member extends through the elongated shaft to operatively couple to the end effector to a drive mechanism. The drive mechanism includes an actuator operable to induce longitudinal motion in the tensile member, and longitudinal motion in the tensile member induces movement of the end effector. A tensioning mechanism is provided to impart a proximally directed force on the drive mechanism such that the proximally directed force is transmitted to the tensile member. Thus, the tensile member may be maintained in a tensile state over time. | 09-01-2011 |
| 20110213361 | De-Tensioning Mechanism for Articulation Drive Cables - A surgical instrument includes a housing having an elongated shaft extending distally therefrom. An end effector for treating tissue is supported by the elongated shaft. One or more tensile members extend at least partially through the elongated shaft. A proximal end of a tensile member is operatively coupled to at least one actuator and a distal end is operatively coupled to the end effector such that manipulation of the actuator induces movement of the tensile member to move the end effector. A de-tensioning mechanism is operatively associated with the tensile member to move the tensile member between a first relaxed configuration and a second stressed configuration. The de-tensioning mechanism includes a spacer insertable into a cavity defined in the housing to move the tensile member to the first relaxed configuration and removable from the cavity to move the at least one tensile member to the second stressed configuration. | 09-01-2011 |
| 20110213362 | Drive Mechanism for Articulation of a Surgical Instrument - A surgical instrument includes a housing, an end effector and an elongated shaft extending therebetween. The elongated shaft includes a distal portion that is movable between aligned and articulated configurations. A pair of drive cables extends through the elongated shaft and is coupled to the distal portion such that reciprocal longitudinal motion of the drive cables induces movement of the distal portion between the aligned and articulated configurations. An articulation drive mechanism is operable to induce reciprocal longitudinal motion of the drive cables. The drive mechanism includes an actuator and a pair of torsion members that are rotatable about two distinct axes in response to movement of the actuator. A respective follower is operatively coupled to each torsion member to translate in a respective longitudinal direction in response to rotation of the torsion members, and each follower is coupled to a respective drive cable to impart translational motion thereto. | 09-01-2011 |
