摘要： Methods for multi-directional enhanced oil recovery (MEOR) are disclosed that involve removal of oil from a reservoir that has an injection well, a producing well, and a plurality of lenses that contain oil and that each span between the injection well and the producing well. One method, among others, involves recovering primary oil from a primary set of lenses via the producing well by alternating injection one or more times of water and an injection gas, or IG (e.g., carbon dioxide, ethane, natural gas, nitrogen, etc., or any combination thereof) into the injection well so that the water and IG enter the primary set in a first direction and move the primary oil in the first direction. The method further involves recovering secondary oil from a secondary set of lenses that is different than the primary set via the injection well by alternating injection one or more times of water and the IG into the producing well so that the water and carbon dioxide enter the secondary set in a second direction that is different than the first direction (e.g., opposite) and therefore move the secondary oil in the second direction.

摘要： A knee prosthesis includes a femoral component for mounting to the distal end of the patient's femur and a tibial insert component. The femoral component includes a posterior cam extending between the lateral condylar structure and the medial condylar structure. The tibial insert includes a lateral bearing surface, a medial bearing surface, and a raised post portion having a posterior surface adapted to cooperate with the posterior cam of the femoral component. The posterior surface includes a posteriorlateral camming surface and a posteriormedial camming surface and each of the two camming surfaces have different radii of curvature. Between 60° to 90° of knee flexion, the posterior cam of the femoral component engages the raised post portion of the tibial insert and cooperates with the posteriorlateral and the posterior medial camming surfaces to promote posterior translation of the lateral condylar surface on the lateral bearing surface.

摘要： A femoral caliper having one or more anatomical referencing members for placement against portions of the femur, such as the anterior cortex and posterior portion of the femoral condyles, to measure the femur for sizing of the femoral component. A reference mark positioning guide of the femoral caliper is connected to the anatomical referencing member and is capable of guiding placement of a reference mark on the femur that facilitates positioning of the femoral component. The femoral caliper includes an adjustment mechanism capable of displacing the reference mark positioning guide relative to the anatomical referencing member. This allows adjustment of the position of the reference mark (and hence the femoral component) on the femur to account for the up or down sizing of the femoral component. Preferably, the adjustment mechanism adjusts the reference mark positioning guide in the anterior-posterior direction to allow balancing of the tightness or laxity of the selected component.
摘要翻译： 股骨钳具有一个或多个解剖学参考构件，用于放置在股骨部分上，例如股骨髁的前皮质和后部，以测量股骨以确定股骨组件的尺寸。 股骨钳的参考标记定位引导件连接到解剖参考构件，并且能够引导在股骨上引导参考标记的位置，这有利于股骨部件的定位。 股骨钳包括能够相对于解剖学参考构件移动参考标记定位引导件的调节机构。 这允许调整股骨上的参考标记（并且因此股骨部件）的位置以解释股骨部件的上下调整大小。 优选地，调节机构在前后方向上调整参考标记定位导向件，以允许所选择的部件的紧密度或松弛度平衡。

摘要： Knee prosthesis includes a femoral component adapted to fit on a distal end of the femur and a tibial insert component. The femoral component includes a measured anterior/posterior dimension defined by the posterior condyle surface and the interior surface of the anterior flange and a distal peg provided on a distal bone facing surface of each of the lateral and medial condylar structures, wherein the distal pegs are positioned at a midpoint of the measured anterior/posterior dimension. The implant system provides two distinct sizing segments and the tibial insert has a medial tibial aspect ratio of 0.74 and a lateral tibial aspect ratio of 0.65 to 0.68 for all sizes.
