DEFINITION

Classification: 604/19

MEANS FOR INTRODUCING OR REMOVING MATERIAL FROM BODY FOR THERAPEUTIC PURPOSES (E.G., MEDICATING, IRRIGATING, ASPIRATING, ETC.):

(under the class definition) Subject matter including means for conducting body treating material into or out of a body or to or from the external membrane tissue surface of a body to treat said body.

(1) Note. It is to be noted that many devices will include conduits for conducting the material into or out of the body, however, some devices may be merely placed over a body opening to place material in or receive material from the body. An example of the latter form would be nose douches, wherein no tube extends into the nasal passages, but where material may be flushed into the nares and the discharge therefrom received in the device.
