  • Stable microbubbles suspensions injectable into living organisms
    Patent number: 5911972
    Abstract: Gas or air filled microbubble suspensions in aqueous phases usable as imaging contrast agents in ultrasonic echography. They contain laminarized surfactants and, optionally, hydrophilic stabilizers. The laminarized surfactants can be in the form of liposomes. The suspensions are obtained by exposing the laminarized surfactants to air or a gas before or after admixing with an aqueous phase.
    Type: Grant

  • Compositions for imaging of the gastrointestinal tract
    Patent number: 5866100
    Abstract: The invention relates to non-ionic triiodo aromatic compounds and compositions comprising triiodo aromatic polymers useful for X-ray imaging of gastro-intestinal tract. Disclosed compounds are acrylic acid esters of triiodobenzenes with a different degree of reticulation and their polymers/homopolymers. A method of making the polymers, method of making X-ray contrast agents using the polymers and use of the contrast agents is also disclosed.
