High Molecular Weight Multi-Arm Polymers and Medical Hydrogels - US20260108634A1
Summary
Boston Scientific Scimed, Inc. filed patent application US20260108634A1 on October 21, 2025, covering high molecular weight multi-arm polymers and medical hydrogels formed therefrom. The application names Yen-Hao Hsu, Marc Plourde, and Heather Cirka as inventors and specifies reactive multi-arm polymers with molecular weights exceeding 10,000 Daltons for cross-linked hydrogel kits. Patent applications do not grant enforceable rights and create no immediate compliance obligations for third parties.
About this source
USPTO classification A61K covers pharmaceutical preparations: formulations, dosage forms, combination therapies, delivery systems, and the vehicles that carry active ingredients. Every newly published application in A61K lands in this feed, around 245 a month. Applications publish 18 months after filing, so this feed reveals what pharma formulators at major sponsors and generics were working on in the prior year and a half. Watch this if you compete in drug formulation, file freedom-to-operate analyses, scout competitive drug products before clinical readouts, or follow novel delivery platforms like nanoparticles, lipid carriers, and long-acting injectables.
What changed
Boston Scientific Scimed, Inc. published patent application US20260108634A1 covering reactive high molecular weight multi-arm polymers for medical hydrogel formation, with molecular weights greater than 10,000 Daltons. The application specifies a kit comprising the multi-arm polymer with a core and covalently attached polymer segments, plus a multifunctional crosslinking compound.
Third parties should note that published patent applications carry no enforceable rights until granted. Competitors developing similar hydrogel technologies should monitor this application's prosecution for potential claim scope that could affect freedom-to-operate assessments once the patent issues.
