DEFINITION

Classification: 604/27

Material introduced into and removed from body through passage in body inserted means:

(under subclass 19) Subject matter including a body entering means having a channel or channels formed therein for conducting a body treating material into and out of a body.

(1) Note. Obviously many devices for forcing fluid into the body (e.g., a piston type hypodermic syringe) can be used to both inject material into and draw material from the body. To be classifiable in this subclass, a patent must claim separate passages for both injecting and withdrawing material, or must claim injection and withdrawal through a single passage.
