Latest Patents

Motose’s recent patent work includes two catheter inventions.

“Catheter Having Shaft Accommodation Portion That Accommodates and Is Fused to Elongated Shaft” describes a catheter in which the shaft is directly fusion-bonded to a hub at a portion that accommodates the shaft’s proximal end. The design aims to reduce the risk of the shaft separating from the hub during high-pressure contrast-agent injection or withdrawal. By avoiding adhesive, the approach also seeks to improve manufacturing yield and reduce production and safety-related costs.

“Catheter” describes a shaft and hub arrangement designed to secure the components while limiting changes to the hub’s radial dimensions. The hub has a tubular accommodation unit that houses the shaft and is directly welded to its outer surface. The patent describes a residual-strain profile intended to support a firm connection while preserving dimensional accuracy.

Career Highlights

Motose’s listed portfolio comprises 2 patents, both addressing catheter construction and the shaft-to-hub interface. Their stated objectives include improving connection reliability, supporting manufacturing consistency, and reducing the risk of component separation.

Collaborations

Motose is associated with Terumo Corporation. Daisuke Shimada is identified as a coworker.

Conclusion

Yuji Motose’s patent work centers on catheter designs that strengthen shaft-to-hub connections while addressing safety, manufacturing, and dimensional-accuracy considerations.
