| 20090138021 | INSTRUMENT ASSEMBLY FOR USE IN KNEE JOINT REPLACEMENT SURGERY - An instrument assembly for use in knee joint replacement surgery is provided including a base instrument having a tibial plate, a femoral plate, a tibial arm having a plate end and a control end, a femoral arm having a plate end and a control end, wherein the femoral plate is rotatably fastened to the plate end of the femoral arm. The assembly also includes a distractor mechanism configured to act between the tibial arm and the femoral arm at a point between their respective plate ends and control ends by which the distance between the plate ends of the arms can be adjusted and an ancillary instrument mountable on the base instrument and configured such that the position of the ancillary instrument relative to the tibial plate is fixed during subsequent steps in the knee replacement procedure, while the knee joint is distracted as a result of forces applied across the joint between the tibial plate and the femoral plate. | 05-28-2009 |
| 20090270869 | DISTRACTOR INSTRUMENT - A distractor instrument for use in knee joint surgery is provided that includes a tibial plate, a femoral plate, a tibial arm having a plate end and a control end, wherein the tibial plate is fastened to the plate end of the tibial arm at its anterior edge, and wherein, when the tibial plate is engaged with the tibia, the tibial arm is configured to extend from the tibial plate generally medially or laterally of the knee joint. The distractor instrument also includes a femoral arm having a plate end and a control end, wherein the femoral plate is fastened to the plate end of the femoral arm, and wherein, when the femoral plate is engaged with the femur, the femoral arm extends from the femoral plate generally aligned with the tibial arm. The tibial arm and the femoral arm are pivotably connected to one another at a point between their respective plate and control ends so that pivotal movement of the femoral arm relative to the tibial arm reduces the distance between their control ends and causes the distance between the tibial plate end and the femoral plate end to increase. | 10-29-2009 |
| 20100131021 | LOCATING A BONE AXIS - A technique for locating an axis of a bone, which extends through the centre of rotation of the bone around a joint between that bone and another bone, involves a. moving the bone in a plane about the said joint, between a first point and a second point, b. locating a third point which is equidistant from the first and second points, and c. locating the axis which passes through the third point, perpendicular to a line which connects the first and second points. The invention provides an instrument for performing this technique. | 05-27-2010 |

| 20110040045 | REVERSIBLE DERIVATIZATION OF POLY (ARYL ETHER KETONES) - The embodiments of the present disclosure present systems and methods for the reversible solubilization of (aryl ether ketones) (PAEKs). A thioacetalization process is employed to modify the PAEKs into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. This modification allowing selected analysis techniques to be more easily performed on PAEKs1 such as gel permeation chromatography. The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for non-destructive characterization of the PAEK. Advantageously, the thioacetalization process is generally applicable to a broad range of PAEKs, unlike presently known methods of solubilizing PAEKs. Solubilization of PAEKs further expands the utility of the PAEKs, opening up additional routes to chemical modification of PAEKs, as well as allowing for the possibility of processing PAEKs from solution. | 02-17-2011 |

| 20100218436 | TRANSPORTABLE BUILDING MODULE WITH TWO STRUCTURES - A transportable building module includes a first structure for defining a first enclosed space when erected at a building site and at least one elongate structural component having at least two elements that are relatively linearly slideable for linearly extending the structural component. The structural component is part of or attached to the first structure and is upright when the first structure is installed at the building site, whereupon the structural component is linearly extensible to provide part of a second structure for defining a second enclosed space above the first space. | 09-02-2010 |
