| 20100234962 | CONSTRAINED PROSTHETIC KNEE WITH ROTATING BEARING - A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component. | 09-16-2010 |

| 20110009973 | METHODS AND APPARATUSES FOR ATTACHING TISSUE TO ORTHOPAEDIC IMPLANTS - Methods and apparatuses for attaching tissue structures to orthopaedic implants. In one exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal tibial implant. In another exemplary embodiment, the methods and apparatuses are used to attach soft tissue and/or bone to a proximal femoral implant. | 01-13-2011 |

| 20090222007 | MODULAR STEM EXTENSION - The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head. | 09-03-2009 |

| 20110094140 | Adjustable Recoil Reducing Shooting Rest - An adjustable recoil reducing shooting rest disclosed. The shooting rest may be adjusted to absorb differing amounts of recoil from various rifles to prevent rifle any bounce that may add to aim inaccuracy. The user may also adjust both the horizontal and vertical aim of the rifle to consistently aim at the same location after multiple shots. The shooting rest may be secured to an unmodified support surface, and the rest consistently supports the butt stock of the rifle regardless of the vertical angle of the rest. | 04-28-2011 |

| 20110062512 | NONPLANAR DEVICE WITH THINNED LOWER BODY PORTION AND METHOD OF FABRICATION - A nonplanar semiconductor device having a semiconductor body formed on an insulating layer of a substrate. The semiconductor body has a top surface opposite a bottom surface formed on the insulating layer and a pair of laterally opposite sidewalls wherein the distance between the laterally opposite sidewalls at the top surface is greater than at the bottom surface. A gate dielectric layer is formed on the top surface of the semiconductor body and on the sidewalls of the semiconductor body. A gate electrode is formed on the gate dielectric layer on the top surface and sidewalls of the semiconductor body. A pair of source/drain regions are formed in the semiconductor body on opposite sides of the gate electrode. | 03-17-2011 |
