Publication number: 20200345502Abstract: A tibial insert includes an articular surface and a bottom surface opposite the articular surface. The bottom surface includes one or more bone-conserving features. In some embodiments, the bottom surface may be curved to match a curvature of the articular surface such that a thickness of the tibial insert is relatively constant. In other embodiments, the bottom surface may be relatively planar but include a protrusion extending from a planar base surface to maintain a minimum thickness of the tibial insert. The described features may be incorporated in a uni-compartmental tibial prosthesis, a bi-compartmental tibial prosthesis, or a total knee prosthesis.Type: ApplicationFiled: April 30, 2020Publication date: November 5, 2020Inventors: Stephen E.

Patent number: 10519757Abstract: 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.Type: GrantFiled: August 7, 2018Date of Patent: December 31, 2019Inventors: Frank Thomas Graff, Jr., Reuben L. Graham, William J. Maloney
