Class Information
Number: 604/131
Name: Surgery > Means for introducing or removing material from body for therapeutic purposes (e.g., medicating, irrigating, aspirating, etc.) > Treating material introduced into or removed from body orifice, or inserted or removed subcutaneously other than by diffusing through skin > Material introduced or removed through conduit, holder, or implantable reservoir inserted in body > Treating material forced into or out of body by self-acting fluid pressure, motor-driven, or mechanical energy storing means (e.g., pressure infusion or aspiration, etc.)
Description: Subject matter wherein body treating material is thrust into or expelled from the body by (a) fluid pressure which does not require the application of force by a person during the injection, (b) an apparatus powered by a device which converts any form of energy into mechanical energy, or (c) a mechanical device capable of sorting energy.
