发明名称 Methods of making composite prosthetic devices having improved bond strength
摘要 A method of making a composite prosthetic device, such as a hernia repair device, includes providing a support layer, juxtaposing a layer of an absorbable material with the support layer, and disposing an absorbable adhesive between the support layer and the layer of an absorbable material. The method includes heating the layers for melting the absorbable adhesive so as to bond the support layer with the layer of the absorbable material. Before the heating step, the moisture content of at least one of the layers is increased for improving thermal conductivity between the layers so as to enhance the strength of the bonds formed between the layers. The moisture content may be increased by exposing at least one of the layers to an environment having elevated relative humidity. In one embodiment, the support layer is polypropylene mesh, the layer of the absorbable material is oxidized regenerated cellulose, and the absorbable adhesive is polydioxanone.
