Patent number: 11852639Abstract: A microfluidic, chip-based assay device has been developed for measuring physical properties of an analyte (particularly, whole blood or whole blood derivatives). The technologies can be applied to measure clotting times of whole blood or blood derivatives, determine the effects of anticoagulant drugs on the kinetics of clotting/coagulation, as well as evaluate the effect of anticoagulant reversal agents. These technologies can additionally be used to optimize the dosage of anticoagulation drugs and/or their reversal agents. The assay is independent of the presence of anticoagulant; clotting is activated by exposure of the blood sample in the device to a glass (or other negatively charged material such as oxidized silicon) surface, which activates the intrinsic pathway and can be further hastened by the application of shear flow across the activating materials surface.Type: GrantFiled: February 2, 2022Date of Patent: December 26, 2023Assignee: Perosphere Technologies Inc.Inventors: Sasha Bakhru, Bryan Laulicht, Stefan Zappe, Solomon Steiner

Patent number: 10092641Abstract: Methods and compositions for delivering antigens to the lymphatic system in doses that desensitize patients to future exposure to antigens have been developed. Rapid desensitization is achieved by introducing small quantities of antigen into the lymphatic system. In preferred embodiments, the compositions are administered to yield therapeutically effective levels of antigen within the lymph, where macrophages reside in the greatest concentration, by intradermal administration, using for example, microneedles or micro articles, oral administration, using for example, enteric coated capsules or tablets, or autologous transfusion. In some embodiments, the methods and compositions for delivering antigens orally achieve uptake by the Peyer's patches of the small intestines.Type: GrantFiled: April 6, 2017Date of Patent: October 9, 2018Assignee: Perosphere Technologies Inc.Inventors: Bryan E. Laulicht, Sasha H. Bakhru, Solomon S. Steiner, Edith Mathiowitz
