Publication number: 20180252734Abstract: 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: ApplicationFiled: March 1, 2018Publication date: September 6, 2018Inventors: Sasha Bakhru, Bryan Laulicht, Stefan Zappe, Solomon Steiner

Patent number: 9907704Abstract: Methods and compositions for securing to and removing adhesive tapes from substrates, e.g., delicate substrates such as skin, are described. The methods include providing an adhesive tape comprising an adhesive layer and a support layer in contact with the adhesive layer. A first adhesion level between the adhesive layer and the support layer is, or can be controlled to be, less than a second adhesion level between the adhesive layer and the substrate. The methods further include applying the adhesive tape to the substrate by contacting the adhesive layer to the substrate while the support layer remains in contact with the adhesive layer; and removing the support layer from the substrate by separating the support layer from the adhesive layer.Type: GrantFiled: June 6, 2013Date of Patent: March 6, 2018Assignees: The Brigham and Women's Hospital, Inc., Massachusetts Institute of TechnologyInventors: Bryan Laulicht, Jeffrey M.

Publication number: 20170324069Abstract: A battery for use in electronic devices and which is safely ingested into a body and a related method of making the battery. The battery includes an anode, a cathode and a quantum tunneling composite coating. The quantum tunneling composite coating covers at least a portion of at least one of the anode or the cathode and provides pressure sensitive conductive properties to the battery including a compressive stress threshold for conduction. The compressive stress threshold may be greater than a pre-determined applied stress in a digestive tract of the body in order to prevent harm if the battery is ingested. The battery may include a waterproof seal that extends between the quantum tunneling composite coating and a gasket separating the anode and cathode to inhibit the battery from short circuiting in a conductive fluid below the compressive stress threshold.Type: ApplicationFiled: July 21, 2017Publication date: November 9, 2017Inventors: Bryan Laulicht, Janet Freilich, Jeffrey M. Karp, Robert Langer

Patent number: 9165703Abstract: An effective method for prolonging localization of therapeutics within the rat gastrointestinal tract of at least about 12 hours is provided. The method includes localization of therapeutic agents that are nanoparticulated or nanoencapsulated. Attractive forces between an orally administered magnetic dose and an external magnet were monitored and internal dose motion in real time using biplanar videofluoroscopy was visualized. Tissue elasticity was quantified as a measure of tissue health by combining data streams. The methods address safety, efficacy, and monitoring capacity of magnetically localized doses and show a platform for testing the benefits of localized drug delivery.Type: GrantFiled: December 21, 2011Date of Patent: October 20, 2015Assignee: BROWN UNIVERSITYInventors: Bryan Laulicht, Edith Mathiowitz

Publication number: 20150209509Abstract: An apparatus provides targeted placement of openings for infusing fluids into a body. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus due to contraction of an element made of interlaced flexible elements. A multi-opening needle is provided in some embodiments wherein placement of one of the openings in a target region with a relatively lower external pressure allows pressurized fluid to exit the needle while openings remaining in higher pressure, non-target regions do not release substantial amounts of the fluid.Type: ApplicationFiled: August 7, 2013Publication date: July 30, 2015Applicants: The Brigham and Women's Hospital, Inc., Massachusetts Institute of TechnologyInventors: Eoin D.
