DEFINITION

Classification: 604/528

With means to advance or steer catheter, excluding remotely controlled devices:

(under subclass 523) Subject matter for means to guide the catheter as it is advanced into a body passage, vessel, or cavity thereby preventing any damage to internal organs and tissue.

(1) Note. Mechanically remote control devices are not appropriate subject matter for this subclass.

(2) Note. The guidewire is usually made of a material and/or in such a manner (e.g., coils) as to be more pliant than the catheters and/or any tool, which accompanies the catheter. It may occupy the same lumen as the work tool, in single bore catheters or as in plural bore catheters the guidewire and work tool may occupy different spaces.
