DEFINITION

Classification: 604/264

Body inserted tubular conduit structure (e.g., needles cannulas nozzles, trocars, catheters, etc.):

(under subclass 93) Subject matter wherein significance is attributed to the structure of an elongated, hollow tube, per se, which is inserted within the body and is utilized solely to introduce body treating material into or remove material from the body during surgical procedures.

(1) Note. Combinations of body inserted tubes with containers or receptacles not classifiable higher in the schedule will be classified herein. Patents claiming a nonbody inserted conduit in combination with a container/receptacle will be classified in the appropriate container/receptacle subclass. To be classified herein otherwise, the tube structure must be claimed as inserted into the body.
