  • Method and devices for a sub-splenius/supra-levator scapulae surgical access technique
    Patent number: 11937797
    Abstract: A novel posterolateral inter-muscular approach has been developed to access the cervical. spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises: i) an anterior superior border of the trapezius muscle; ii) an anterior inferior border of the splenius capitis muscle, and iii) a posterior superior border of the levator scapulae muscle. Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.
    Type: Grant

  • Blood separation media
    Patent number: 8404194
    Abstract: Disclosed is a separation media, comprising an upstream layer, comprising fibers, wherein the upstream layer has a mean flow pore size of 8 microns or less; and a downstream layer, comprising fibers. The separation media is designed to separate red blood cells from liquid specimens such as blood and allow a filtrate, such as blood plasma, to flow from said downstream layer. Also provided is a diagnostic test device incorporating the separation media. Further disclosed is a method for separating red blood cells from a liquid specimen.
