Asahi Intecc Guide Wire with Protruding Resin Layer
Summary
USPTO published patent application US20260097188A1 for Asahi Intecc Co., Ltd. covering a guide wire assembly with a core shaft, coil body, and protruding resin layer extending through gaps in the coil into a void between the coil and shaft. The application was filed December 11, 2025 and published April 9, 2026. Medical device manufacturers should monitor competitor patent filings in interventional catheter and endovascular device technology.
What changed
USPTO published patent application US20260097188A1 for a guide wire medical device invented by Asahi Intecc Co., Ltd. The device comprises a core shaft, a wound coil body forming a void between the coil and shaft, and a resin layer with a protruding portion that extends inward through gaps between adjacent coil wires into the void. The invention relates to CPC classifications A61M 25/09 and related subclasses covering vascular guide wires.
Medical device manufacturers developing guide wires, catheter systems, or endovascular delivery devices should monitor this application for potential overlap with their own technologies. While the patent is not yet granted, the published claims provide insight into Asahi Intecc's design direction around coil-to-shaft bonding in guide wire assemblies. Competitors in interventional cardiology, radiology, and neurovascular device markets should conduct freedom-to-operate analyses for any overlapping product lines.
What to do next
- Monitor competitor patent filings in guide wire and endovascular device technology
- Review design freedom and potential licensing needs for similar coil/resin guide wire configurations
- Track prosecution history for claims breadth and potential design-arounds

Abstract
A guide wire includes a core shaft, a coil body that is a wire wound around the core shaft, and a resin layer covering at least an outer peripheral surface of the coil body. The coil body includes a spaced part in which a gap is formed between adjacent wires, and is arranged to form a void between the coil body and the core shaft. The resin layer includes a protruding portion protruding inside the void toward the core shaft through the gap between the adjacent wires in the spaced part. The protruding portion extends toward the core shaft in a direction away from an inner peripheral surface of the coil body.
