Abstract
A medical ultrasound coupling media and lubricant, in gel or liquid form, comprised of polyethylene oxide (PEO), at least one of polyalkylene glycols and polyhydric alcohols, and the balance water. The inventive coupling media provides long-term biocompatibility (bio-inert, bio-erodable or biodegraded and excreted) in vivo with human tissue and body fluids. The ultrasound coupling and lubricating media is formulated and manufactured in such manner and form that produces higher viscosity gels with decreased amounts of polymer and renders the acoustic media sterile, non-cross-linked, pseudoplastic, and containing acceptably low levels of pyrogens.
