Neurocatheters, Systems, and Methods of Use
Summary
USPTO published patent application US20260097183A1 for neurocatheter technology. The patent covers catheters with proximal and distal portions having different stiffness ratios (proximal portion stiffer than distal by at least 10x). The catheter is configured for intracranial vessel access without requiring a guide sheath. Inventors: Paul De Lipski, John Miller, Tony M. Chou, Stephanie Sharpe, Christina Van. Filing date: 2025-10-03.
What changed
USPTO published patent application US20260097183A1 covering neurocatheter devices with a novel stiffness gradient design. The proximal portion of the catheter body is at least 10 times stiffer than the distal portion, enabling advancement through patient vasculature without a guide sheath while preventing proximal portion prolapse. The design allows the distal portion to reach intracranial vessels.\n\nManufacturers developing neurovascular or catheter-based devices should review this application to assess potential overlap with their own technologies. Patent monitoring is recommended for competitive intelligence and freedom-to-operate analysis. Medical device researchers may find the stiffness gradient design relevant to similar product development efforts.

Abstract
A catheter comprising a catheter body defining an inner lumen having a working length between a proximal end and a distal end of the catheter body, wherein the catheter body comprises a proximal portion and a distal portion, wherein the proximal portion is stiffer than the distal portion by at least 10×, wherein the catheter is configured to be advanced through a patient's vasculature without a guide sheath so the distal portion reaches an intracranial vessel without prolapse of the proximal portion without aid of a guide sheath. Related devices, systems, kits, and methods are provided.
