    摘要： Assembly comprising a gas-filled microvesicle and a structural entity which is capable to associate through an electrostatic interaction to the outer surface of said microvesicle (microvesicle associated component—MAC), thereby modifying the physico-chemical properties thereof. Said MAC may optionally comprise a targeting ligand, a bioactive agent, a diagnostic agent or any combination thereof. The assembly of the invention can be formed from gasfilled microbubbles or microballoons and a MAC having a diameter of less than 100 pm, in particular a micelle and is used as an active component in diagnostically and/or therapeutically active formulations, in particular for enhancing the imaging in the field of ultrasound contrast imaging, including targeted ultrasound imaging, ultrasound-mediated drug delivery and other imaging techniques such as molecular resonance imaging (MRI) or nuclear imaging.

    摘要： The invention concerns a method for administering bioactive substances to patients at selected sites in the body and remotely promoting delivery of said media to selected organs or tissues in the body. The method comprises providing an administrable formulation comprising, dispersed in an aqueous carrier liquid, liposomes filled with bioactive substances and gas-filled microspheres, injecting said formulation into the circulation of a patient so that it is directed to a site of interest, and applying ultrasound pulses to said site so as to make the gas-filled microbodies explode and the gas confined therein to expand in the carrier liquid, the energy of expansion of said confined gas causing the liposome vesicles to open and release the trapped substances at said site. Also disclosed are formulations for delivery of biologically active substances to selected target sites in the organism, the formulations comprising an aqueous suspension of gas-filled microvesicles and liposomes filled with active susbstances such as drugs or diagnostic agents. The formulations are available in a kit form in which the kit comprises sterile precursor components.

    摘要： The invention relates to injectable media for ultrasonic echography in the form of microbubbles or microballoons comprising at least two biocompatible substances A and B (gaseous at the body temperature) forming a mixture which when in suspension with usual surfactants, additives and stabilisers provides useful ultrasound contrast agents. At least one of the components (B) in the mixture is a gas whose molecular weight is greater than 80 daltons and whose solubility in water is below 0.0283 ml per ml of water at standard conditions. The presence of the first component (B) in the contrast medium may vary between 0.5 and 41 volume percent. The other component (A) of the ultrasound contrast media is a gas or a mixture of gases whose molecular weight is below 80 daltons. The second component is present in a proportion of between 59-99.5% by vol., and is preferably chosen from oxygen, air, nitrogen, carbon dioxide or mixtures thereof. Gas mixtures described are found to be very effective as ultrasound contrast media. The invention also comprises a method of making the ultrasound contrast medium, the contrast agent and the ultrasound agent kit.

    摘要： Disclosed are injectable suspensions of gas filled microbubbles in an aqueous carrier liquid usable as contrast agents in ultrasonic echography. The suspensions comprise amphipathic compounds of which at least one may be a laminarized phospholipid as a stabiliser of the microbubbles against collapse with time and pressure. The concentration of phospholipids in the carrier liquid is below 0.01% wt but is at least equal to or above that at which phospholipid molecules are present solely at the gas microbubble-liquid interface. Also disclosed is a method of preparation of the stable suspensions of air or gas filled microbubbles.
