About this source
USPTO classification A61M covers devices that introduce or withdraw fluids from the body: infusion pumps, catheters, syringes, inhalers, wound drainage, dialysis equipment, and fluid-handling microfluidics. Every newly published application in A61M lands in this feed, around 205 a month. Applications publish 18 months after filing. Watch this if you compete in infusion therapy or drug delivery, file freedom-to-operate analyses for medical device startups, scout acquisition targets in cardiovascular or respiratory devices, or track hospital R&D arms that are quietly patenting clinical innovations.
What changed
USPTO published patent application US20260108423A1 for a medical kit comprising a vial and male connector. The invention describes a male connector with a male part having an outer surface extending around an axis and tapering toward a free end, featuring a sleeve with an internal thread. The outer surface comprises a first frustoconical portion forming a first angle with the axis and a second frustoconical portion extending toward the free end forming a second angle less than the first.
Medical device manufacturers developing drug transfer or injection systems may wish to review this application for potential prior art or licensing considerations. The dual-angle frustoconical design specified in the claims represents a defined technical approach to vial-connector interfaces.
