Abstract: A medical ultrasound coupling media and lubricant, in gel or liquid form, comprised of polyethylene oxide (PEO), and aqueous solvent solutions. 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 renders the acoustic media sterile, non-cross-linked, pseudoplastic, and containing acceptably low levels of pyrogens.

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.

Abstract: A homogeneous, solid, elastic, biocompatible sheath which is conformal and performs as if integral to the diagnostic and/or therapeutic medical ultrasound transducer, and comprised of 20 to 95% biocompatible liquid, preferably about 70% to about 95% biocompatible liquid, that render properties to the sheath resulting in the desirable level of acoustic coupling, with acceptable low levels of acoustic artifacts, distortion and attenuation and provides a microbial barrier between the transducer and a surgical field or skin. Such sheaths are fabricated from a group of hydrophilic block co-polymers whose chemistry and physical properties provide ability to form products by dipping, casting, molding or extrusion.
