  "patent_number": "US 12734331",
  "country": "US",
  "title": "How a Compact Central Catheter Insertion Kit Works",
  "original_title": "Compact insertion assemblies of rapidly insertable central catheters and methods thereof",
  "summary": "This patent describes a clever way to make the tools for inserting a central catheter much smaller and easier for doctors to use by looping a guidewire inside the assembly.",
  "what_it_does": "The patent abstract describes a compact rapidly insertable central catheter (RICC) insertion assembly. This assembly includes a RICC, an introducer assembly, an access guidewire, and a coupler. The RICC itself contains a catheter tube, a catheter hub, and extension legs. The introducer assembly includes a needle connected to a syringe. The key innovation, as described in the abstract, is the coupler which enforces a loop in the access guidewire. This looping action allows the catheter tube to follow the guidewire's path, making the entire assembly smaller and easier to handle. For example, a medical professional could quickly deploy a central line with a pre-assembled kit that takes up less space and is less cumbersome than traditional designs.",
  "what_it_does_not_cover": [
    "Does not cover central catheter insertion assemblies that achieve compactness without a coupler enforcing a guidewire loop.",
    "Does not cover non-central catheters, such as peripheral intravenous catheters.",
    "Does not cover central catheter insertion methods that do not involve a guidewire.",
    "Does not cover introducer assemblies that are not coupled to the RICC.",
    "Does not cover compact catheter assemblies that achieve their small size through different mechanical arrangements."

  "abstract": "Disclosed are compact rapidly insertable central catheter (“RICC”) insertion assemblies and methods. For example, a RICC insertion assembly can include a RICC, an introducer assembly, an access guidewire, and a coupler coupling together the RICC and the introducer assembly. The RICC can include a catheter tube, a catheter hub, and one or more extension legs connected in the foregoing order. The introducer assembly can include an introducer needle coupled to a syringe. The introducer needle can include a needle-hub through hole passing through a needle hub and connecting to a needle-shaft lumen of a needle shaft. The access guidewire can include a proximal portion disposed in the RICC and a distal portion disposed in the needle-shaft lumen through the needle-hub through hole. The coupler can enforce a loop in the access guidewire over which the catheter tube follows, thereby compacting the RICC insertion assembly and making it easier to handle.",
