Class Information
Number: 604/133
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 exhausted from body by expansion of contracted elastic receptacle or resilient means therein
Description: Subject matter including a resilient chamber which under compression is allowed to expand, either from its own natural resiliency or from resilient means within the chamber, to draw or suck material into the chamber.
