Class Information
Number: 604/145
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.) > Material impelled by pressurized charge of gas or vacuum > Pressurizing gas generated by chemical reaction
Description: Subject matter wherein the gas pressure is caused by a chemical interaction between gas generating components which when released within a reservoir pressurizes the contents to expel said contents.
