Abstract: The invention relates to 4 serum peptide patterns for diagnostics of intracranial hemorrhagic stroke (ICH) in humans and differential diagnosis from acute ischemic stroke that are defined using a list of the 34 quantitative peptides that in sera of patients with ICH are increased 2 folds or more as compared with individuals without stroke and patients with acute ischemic stroke and a list of 16 qualitative peptides detectable in sera of the patients with ICH but not detectable in the sera of individuals without stroke and in sera of patients with acute ischemic stroke.

Abstract: The invention relates to the method for sample preparation for qualitative and quantitative analysis of peptidome in serum based on amino acid sequencing with a tandem mass spectrometry (MS) tool with signaling intensities measurement of peptides, characterized in that the method comprises the following steps: one step enrichment of peptides in the analyzed serum sample and removing of proteins equal or bigger than 15 kDa from peptide enriched. The second invention is a data analysis workflow for quantitative analysis of the peptides sequenced with tandem mass spectrometry.

Abstract: The invention relates to 5 serum peptide patterns for diagnostics of acute ischemic stroke (AIS) in humans and differential diagnosis from the intracranial hemorrhagic stroke that are defined using a list of the 100 quantitative peptides that in sera of patients with AIS are increased 2 folds or more as compared with individuals without stroke and patients with intracranial hemorrhagic stroke and a list of 54 qualitative peptides detectable in sera of the patients with AIS but not detectable in the sera of individuals without stroke and in sera of patients with intracranial hemorrhagic stroke.

Abstract: Devices and methods are provided for optimized spinal fixation using additive manufacturing techniques to create implants with optimized structure for various surgical approaches, anatomies, etc. One exemplary embodiment includes a cage having an X-shaped connection that can bear a load during cage impaction. The cage can be additively manufactured to incorporate features such as variable wall thickness or material density to adjust properties of the cage, including load bearing capability, flexibility, radiolucency, etc. The cage can further include one or more of the connectors disposed between upper and lower endplates. In some embodiments, the cage can include a feature for coupling an insertion device thereto for introducing the cage into the body of a patient. In some embodiments, a plate can be appended to or integrally formed with a proximal end of the cage to assist with securing the cage to vertebral bodies.

Abstract: A catheter device that includes a double-threaded guidance wire that allows multiple use of a compliant cavity creation device (i.e., treatment of more than one level). The double-threaded guidance wire may be connected with the luer part of the device and a distal part of the balloon using a threaded engagement to avoid lengthening of the inner tube, avoid lengthening of the balloon, and to limit the plastic deformation of the system in axial direction. In other implementations, the double-threaded guidance wire may be reconnected to the distal part of the balloon with a distal thread of the double-threaded guidance wire in order to restore the nominal length.

Abstract: Described herein is a balloon catheter with a zero-profile tip—that is, a balloon catheter having a distal tip that does not extend beyond the boundary of the cavity that will be created by the balloon when inflated—and further described herein are methods for the manufacturing of same. Several embodiment feature a method for inverting the distal end of an inflatable balloon structure, said inflatable balloon structure having a middle region, a first end region with a first opening, and a second end region with a second opening, said method comprising: (1) centrally inverting the second end region of the inflatable balloon structure and passing it through the first opening; (2) permanently fixing the inverted second end region to prevent un-inversion; and (3) returning the second end region back through the first opening.
