How a Compact Central Catheter Insertion Kit Works

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 covers

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 doesn't 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.

The clever bit

The clever bit is using a coupler to intentionally create a loop in the access guidewire, allowing the catheter tube to follow this loop. This unique internal arrangement significantly compacts the entire insertion assembly, making it much easier to manage and deploy.

Why it matters

Central catheters are vital for delivering medications, fluids, or monitoring patients in hospitals. Making the insertion assembly compact and easier to handle can improve efficiency during critical medical procedures. This design aims to streamline the process for healthcare providers, potentially reducing setup time and improving workflow, especially in fast-paced or emergency settings.
