METHODS OF MAKING COMPOSITE PROSTHETIC DEVICES HAVING IMPROVED BOND STRENGTH
First Claim
1. A method of making a composite prosthetic device comprising:
- providing a support layer;
juxtaposing a layer of an absorbable material with said support layer;
disposing an absorbable adhesive between said support layer and said layer of an absorbable material;
heating said layers for melting said absorbable adhesive so as to bond said support layer with said layer of an absorbable material; and
increasing the moisture content of at least one of said layers for improving thermal conduction between said layers.

Abstract
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.

17. A method of making a composite prosthetic device comprising:
-
assembling a multilayer structure including a first support layer having a first surface and a second surface; a second layer of an absorbable adhesive overlying the first surface of said first layer; a third layer of an absorbable adhesive overlying the second surface of said first layer; a fourth layer of an absorbable material overlying said third layer of an absorbable adhesive; heating said assembled multilayer structure to melt said second and third layers of an absorbable adhesive so as to bond said first and fourth layers together; and prior to the heating step, increasing the moisture content of at least one of said layers for improving thermal conductivity throughout said assembled multilayer structure during the heating step. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
