The present invention relates to an absorbable biomedical composite material and a preparation method therefor, wherein the absorbable biomedical composite material comprises: a substrate particle containing a calcium phosphate compound; an intermediate layer which is coated on the surfaces of the substrate particle and has a first glass transition temperature, the first glass transition temperature being not higher than a normal body temperature; and a polymer matrix which is formed on the outer surface of the intermediate layer and has a second glass transition temperature, the second glass transition being higher than the first glass transition temperature. The present invention can provide an absorbable biomedical composite material which not only increases the mechanical strength but also improves the toughness.

Biomedical composite material and preparation method therefor

Provided are an absorbable biomedical composite material and a preparation method therefor. The absorbable biomedical composite material comprises: substrate granules containing a calcium-phosphorus compound; an intermediate layer which is coated on the surface of each of the substrate granules and has a first glass transition temperature, the first glass transition temperature being not higher than normal human body temperature; and a polymer matrix which is formed on the outer surface of the intermediate layer and has a second glass transition temperature, the second glass transition being higher than the first glass transition temperature. The absorbable biomedical composite material has increased mechanical strength and also improved toughness.

Absorbable biomedical composite material and preparation method therefor

An absorbable occluder () comprises a woven mesh (), wherein the woven mesh () comprises at least two polymer filaments with different centralized degradation time periods, or comprises a polymer filament made by blending at least two polymers with different centralized degradation time periods. The absorbable occluder () can avoid the tissue inflammatory response caused by the polymer filaments of the woven mesh () centralized degrading within the same period.
