Latest Patents

Yamada’s listed patents include a cutting device and a steerable catheter.

The cutting-device patent describes two contact members that can open and close, a mechanism that brings them into contact with a target portion, and a cutting mechanism that cuts the target while the members hold it in place. The invention also relates to forceps and a gripping-and-cutting method.

The steerable-catheter patent describes a flexible tube with a sheath section and a porous deflection section. The deflection section becomes stiffer when compressed axially and returns to a softer state when the compression is released. Wires can apply and release the compression force and help deflect the section. The design aims to improve both catheter maneuverability and insertability.
