Abstract: A gallium silica glass composition is described. The glass can be used in variety of biomedical applications.

Abstract: An inflation balloon 1 comprising a compliant balloon wall 3 and a first 5 and second 10 set of non-compliant filamentous members embedded in the balloon wall. The filamentous members are arranged to be slack so as to allow inflation of the inflation balloon, but to restrain the balloon to an expanded diameter when all of the slack has been taken up by expansion of the balloon. The first filamentous members undergo controlled failure to expand the balloon to a second larger expanded size.

Abstract: A bone cement comprises a zinc-based glass and polyalkenoate acid. In addition, the cement comprises a controlled amount of tri-sodium citrate (Na3C6H5O7) (“TSC”). The cement has enhanced rheology without negatively impacting on the mechanical properties. Controlled addition of TSC significantly improves the rheology of the bone cements, increasing working and setting times (illustrated in FIG. 1). For three formulations of the working time can be adjusted from less than 50 seconds to almost 120 seconds; concomitantly working times improve from 58 seconds to duration in excess of 300 s.
