<p>A developable biodegradable microspheric blood vessel embolism material, comprises a biodegradable material which can be embedded in blood vessel, and X-ray opaque developable material, in which, the developable material is packed by the biodegradable material and forms granule structure. The embolism material is biodegradable, can be surveilled under X-ray, can drift to twig blood vessel along with blood flow, and is easy to produce. A developable biodegradable microspheric blood vessel embolism material containing medicine, comprises a biodegradable material which can be embedded in blood vessel, X-ray opaque developable material and medicine, in which, the developable material and the medicine are packed by the biodegradable material and form granule structure. The embolism materials can target administration, simultaneously embolize blood vessel.</p> |
