Abstract: A system may be configured to maintain spacing between a superior spinous process and a superior lamina, and an inferior spinous process and an inferior lamina, of adjacent vertebrae of a spine. The system may include an implant that includes two superior wings that extend superiorly from a proximal superior surface such that, in an implanted position, the superior spinous process may be engaged therebetween. The implant may also include two inferior wings that extend inferiorly from a proximal inferior surface such that, in the implanted position, the inferior spinous process may be engaged therebetween. The system may include a clamp that includes two superior arms configured to engage the two superior wings to prevent disengagement of the two superior wings from the superior spinous process and two inferior arms configured to engage the two inferior wings to prevent disengagement of the two inferior wings from the inferior spinous process.

Abstract: Systems and methods are disclosed for maintaining spacing between a superior spinous process and a superior lamina, and an inferior spinous process and an inferior lamina of adjacent vertebrae of a spine. A system may include an implant having a proximal superior surface with a superior concavity shaped to receive the superior spinous process, a proximal inferior surface with an inferior concavity shaped to receive the inferior spinous process, a distal superior surface, distal to the proximal superior surface, that faces the superior lamina, and a distal inferior surface, distal to the proximal inferior surface, that faces the inferior lamina. The implant may further have a threaded member extending along a proximal-distal direction, that rotates to urge the implant to move from a retracted configuration to a deployed configuration by urging the distal superior surface and the distal inferior surface to move apart.

Abstract: An expandable intervertebral implant that includes an upper endplate having: a proximal end with a proximal ramp, and a distal end with a distal ramp. The proximal ramp includes a pair of upper proximal rails and the distal ramp includes a pair of upper distal rails. The expandable intervertebral implant also includes a lower endplate that includes a proximal end, a proximal ramp, a distal end, and a distal ramp. The proximal ramp includes a pair of lower proximal rails and the distal ramp includes a pair of lower distal rails. The at least one of the lower distal rails and the lower proximal rails is closer to a central plane than one or more of the upper distal rails and the upper proximal rails. The central plane divides a left side from a right side of the expandable intervertebral implant.

Abstract: In some implementations, the interbody implant may include an anterior side, a posterior side, a cephalad side, a caudal side, a right side, and a left side. In addition, the interbody implant may include a proximal end and a distal end. The interbody implant may include a mesh having a first set of pores having a first diameter based on a first relationship to a first locus and a second set of pores having a second diameter based on a second relationship to the first locus. Moreover, the interbody implant may include where at least one of the anterior side, posterior side, left side, right side, cephalad side, and caudal side may include the mesh.

Abstract: Method and system for fabricating a thin film composite including providing a porous polymeric substrate membrane having a surface. At least one polyelectrolyte later can be deposited onto the surface of the substrate membrane, which can impart a charge to the surface. The substrate membrane can be immersed into a bath including a nanoparticle solution, thereby depositing at least one nanoparticle-only layer on the substrate membrane to form a thin film composite.

Abstract: The present invention relates to a method of down-sampling data values, said method comprising the step of: -determining a first set of data values comprising an original current data value and values of original data spatially surrounding said current data; -creating a second set of data values based on the first set by clipping an original data value of the first set when a difference between the current data value and said original data value is higher than a threshold; and -low pass filtering the current data value based on the second set of data values. It may be used in, for example, video encoders, video decoders, or portable apparatuses, such as personal digital assistants or mobile phones, said apparatuses being adapted to encode, to decode pictures, to store or to display pictures at a lower spatial resolution.
