Abstract:
Lyophilized lipid compositions, as well as methods for their preparation, are embodied by the present invention. Gas-filled microspheres prepared using the lyophilized lipid composition are particularly useful, for example, in ultrasonic imaging applications and in therapeutic drug delivery systems.
Abstract:
A container comprising an aqueous lipid suspension and a gaseous phase substantially separate from the aqueous stabilizing phase, useful in diagnostic imaging such as ultrasound and magnetic resonance imaging and in therapeutic applications, is disclosed.

Abstract:
A method and apparatus for making vesicles suitable for use as contrast agents in which a container containing an aqueous suspension phase and a separate gas phase is shaken using reciprocating motion. The reciprocating motion is produced by a shaker arm that moves the container in two, substantially perpendicular directions, with the motion in the first direction being along an arcuate path. The overall path of the motion occurs in a figure-8 pattern. The frequency of shaking is at least approximately 2800 RPM, the length of the shaker arm is at least approximately 6 cm, and the angle through which the shaker arm rotates in the first direction is at least approximately 3°. The total length of travel around the figure-8 pattern is at least 0.7 cm.
