Publication number: 20230046514Abstract: A system for delivering an injection of a fluid into a void within a subject is disclosed. A barrel extends from a first end to a second end and forms a lumen extending from the first end to the second end. A plug and a floating seal are arranged within the lumen. A hollow needle includes a distal end with an opening for fluid to flow from the lumen. The plug, the barrel and the floating seal include material and dimensions selected based on a threshold flowrate for a fluid arranged within the lumen to: overcome a force opposed to a force being applied to the fluid in the lumen to move the floating seal and the hollow needle into a tissue of the subject, and succumb to the opposing force to displace the fluid through the opening into the void.Type: ApplicationFiled: June 28, 2022Publication date: February 16, 2023Inventors: Jeffrey Karp, Girish Chitnis, Julien Lamazouade, Mohan K.S. Verma

Publication number: 20210389321Abstract: A system and method is provided for detecting an analyte within a sample. The method includes providing a first electromagnetic radiation to the sample in a manner that resonantly excites mechanical vibrations in the analyte. The method also includes providing a second electromagnetic radiation to the sample so as to interact with vibrating analyte, wherein a third electromagnetic radiation is produced based on the interaction. The method further includes receiving the a third electromagnetic radiation and determining the presence of the analyte based on the received a third electromagnetic radiation.Type: ApplicationFiled: June 4, 2021Publication date: December 16, 2021Inventors: Sumanth Kaushik, Jeffrey Karp, Charles Wynn, Anthony Samir

Patent number: 10568840Abstract: A self-assembled gel composition with enhanced adhesion to cartilage tissue is provided. A cationic agent co-self assembles with a generally regarded as safe (GRAS), low molecular weight (<2,500 Da) gelator, forming homogeneous self-supporting gel that can encapsulate one or more therapeutic agents for controlled release. The composition adheres to connective tissue, e.g., cartilage, to a greater extent and a greater length of time than a self-assembled gel from gelators alone. The composition is used to specifically target connective tissue and deliver one or more therapeutic, prophylactic, or diagnostic agents for controlled release to improve dosing efficacy.Type: GrantFiled: May 8, 2017Date of Patent: February 25, 2020Assignee: The Brigham and Women's Hospital, Inc.Inventors: Jeffrey Karp, Nitin Joshi, Xueyin He, Sachin Bhagchandani

Publication number: 20190204299Abstract: Disclosed here is a generally applicable framework that utilizes massively-parallel single-cell RNA-seq to compare cell types/states found in vivo to those of in vitro models. Furthermore, Applicants leverage identified discrepancies to improve model fidelity. Applicants uncover fundamental gene expression differences in lineage-defining genes between in vivo systems and in vitro systems. Using this information, molecular interventions are identified for rationally improving the physiological fidelity of the in vitro system. Applicants demonstrated functional (antimicrobial activity, niche support) improvements in Paneth cell physiology using the methods.Type: ApplicationFiled: January 4, 2019Publication date: July 4, 2019Inventors: Benjamin E. Mead, Jose Ordovas-Montanes, Alexander K. Shalek, Jeffrey Karp, Robert Langer

Patent number: 9872881Abstract: Bone- and metal-targeted polymeric nanoparticles are provided. Exemplary nanoparticles have three main components: 1) a targeting element that can selectively bind to bone, minerals, or metal ions; 2) a layer of stealth to allow the polymer to evade immune response; and 3) a biodegradable polymeric material, forming an inner core which can carry therapeutics or other diagnostics. Preferred nanoparticles contain a blend of target-element polymer conjugate and polymer that optimizes the ligand density on the surface of the nanoparticle to provide improved targeting of the nanoparticle. The ratio of target-element polymer conjugate to polymer can also be optimized to improve the half-life of the nanoparticles in the blood of the subject. The nanoparticles also exhibit prolonged, sustained release of therapeutic agents loaded into the particles.Type: GrantFiled: November 3, 2014Date of Patent: January 23, 2018Assignees: The Brigham and Women's Hospital, Inc., Massachusetts Institute of TechnologyInventors: Archana Swami, Pamela Basto, Jeffrey Karp, Omid C.

Publication number: 20170319500Abstract: Gels are formed based on generally recognized as safe (GRAS) low molecular weight amphiphilic molecules in a self-assembly process with limited or no heating. A selective range of ratios between an organic solvent and water, or an aqueous solution, in the medium, allows for the GRAS low molecular weight amphiphiles to form a homogeneous self-supporting gel encapsulating agents to be delivered under very mild conditions. Proteins including enzymes, antibodies, and serum albumin are loaded in the self-assembled gels to provide sustained and/or responsive delivery. The encapsulated proteins retain at least 70%, 80%, or 90% of their activity over days in various storage conditions.Type: ApplicationFiled: May 8, 2017Publication date: November 9, 2017Inventors: Jeffrey Karp, Nitin Joshi, Xueyin He, Julian Amirault, Brittany Laramee, Kai Slaughter
