Class Information
Number: 604/525
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 reinforcing structure > Providing varying degrees of flexibility along longitudinal axis
Description: Subject matter wherein either (a) the material is treated such that the physical properties of a cannula differ along the entire length of the lumen or (b) a plurality of materials with differing physical properties are used so that the hardness is not uniform along the length of the lumen.
