Class Information
Number: 604/531
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 > Body inserted tubular conduit structure (e.g., needles, cannulas, nozzles, trocars, catheters, etc.) > Flexible catheter or means (e.g., coupling) used therewith > With shape retaining memory > Temperature activated
Description: Subject matter for a special material incorporated into the catheter, which allows it to alter its shape in response to a change in temperatures.
