Coated bioabsorbable beads for wound treatment |
摘要 |
The invention provides a material for use in a wound dressing or wound implant, the material comprising a plurality of beads, wherein each bead comprises a porous core of a first bioabsorbable material and a substantially non-porous layer of a second bioabsorbable material around the core. The porous core is preferably a sponge formed by freeze-drying a liquid suspension of the first bioabsorbable material. The preferred diameter of the beads is 0.1-4.0 mm, and the beads are preferably dispersed in a liquid or solid matrix. The invention also provides a method of making beads for use in the materials of the invention. |
