Patent

CA 2214737

The invention relates to gaseous microparticles for ultrasonic diagnosis, whose wall material is built up from block copolymers of polyesters of .alpha.-, .beta.- or .gamma.-hydroxycarboxylic acids with linear or star-shaped polyethylene glycols and optionally liquid crystals or whose wall material is built up from polyesters of .alpha.-, .beta.- or .gamma.-hydroxycarboxylic acids and liquid crystals, media that contain these particles for ultrasonic diagnosis, as well as a process for the production of the media and particles.

La présente invention concerne des microparticules à teneur en gaz utilisés pour la technique de diagnostic à ultrasons, dont les parois sont constituées soit de copolymères en masse de polyesters provenant d'acides hydrocarboniques alpha , beta ou gamma et, d'autre part, de polyéthylenglycols linéaires ou étoilés et, éventuellement, de cristaux liquides, soit de polyesters provenant d'acides hydroxycarboniques alpha , beta ou gamma et de cristaux liquides; elle concerne aussi les produits contenant ces particules utilisés pour la technique de diagnostic à ultrasons, ainsi que le procédé de fabrication de ces produits et de ces particules.
