Claims25
A medical application treatment kit comprising a first part comprising a polymer matrix and a second part comprising a gallium silica based glass composition having an acid labile tetrahedral structure, the first part and the second part being combinable to form an ionically crosslinked glass polymer matrix composition wherein gallium from the glass composition is cross linked into and sets the polymer matrix within the human body,
- wherein the second part comprises a structure of the form:
- X—Ga2O3—SiO2—Y—Z
- where:
- X is an oxide of calcium, barium, lanthanum, strontium, beryllium, magnesium, radium or zinc;
- Y is an oxide of phosphorous or boron;
- and
- Z is a chloride salt provided in the form of one or more of CaCl2, BaCl2, SrCl2, MgCl2, NH4Cl, ZnCl2, GaCl3, LiCl, NaCl or KCl.
