DEFINITION

Classification: 604/523

Flexible catheter or means (e.g., coupling) used therewith:

(under subclass 264) Subject matter relating to a pliant conduit to be inserted within a body passage, vessel, or cavity to feed a body treating material, position a medical device, or remove some of the material.

(1) Note. Cannulas and trocar are appropriate subject matter for this subclass.

(2) Note. For a patent to be classified herein, means for the introduction or removal of body affecting material must be claimed. Patents disclosing only tubular structure for other purposes are classified elsewhere.
