Abstract: An aspiration catheter for removing clot from a blood vessel includes a catheter body having a scaffold extending distally from a distal end of the body. An aspiration lumen runs from the distal end to a proximal end of the body, and a central clot-receiving passage in the scaffold is contiguous with the aspiration lumen of the catheter body. A vacuum-resistant membrane covers the scaffold and establishes a clot aspiration path from a distal end of the scaffold to a proximal end of the aspiration lumen, in the catheter body so that applying a vacuum to the proximal end of the aspiration lumen can draw clot into the central clot-receiving passage. The scaffold may have a comical configuration, a cylindrical configuration, or a combination thereof, and at least a distal portion of the scaffold is radially expandable from a delivery configuration to an extraction configuration.

One of the instruments can be a reamer instrument configured to abrade, cut, or otherwise affect tissue along the patient's spine.

Abstract: The present invention relates to the development of and use of genetically modified human differentiated cells coupled with xenotransplantation into animal models to identify injury and disease-specific RNA and/or protein biomarkers. Specifically, the present invention encompasses two complementary methods for biomarker discovery that enable the direct and selective labelling, isolation, and analysis of human-specific RNA and/or proteins from xenotransplantation (or chimeric) animal models. Both methods involve the treatment of animal models with an RNA analog and/or amino acid analog that enables the specific isolation and quantification of human RNAs and/or proteins for the identification of novel human biomarkers for a large array of human injuries and diseases.
