ABSTRACT:
A method of making a fluid impervious seam in a multilaminate fluid impervious medical fabric is disclosed. The multilaminate fluid impervious medical fabric includes at least two layers having different melting points, at least one of the layers is comprised of a fluid impervious material. The method includes overlapping two portions of the multilaminate fluid impervious medical fabric to form an overlapped region wherein the two layers having the innermost position in apposition to one another have a lower melting point relative to the melting point of the fluid impervious material layer. The two portions of multilaminate fluid impervious medical fabric are heat sealed together at the overlap at a temperature which is equal to or greater than the melting point of the innermost identical layers and which temperature is less than the melting point of the fluid impervious material layer. Thus, an integrated fused layer is created from the two layers having the innermost position in apposition to one another, while the fluid impervious material layer remains unmelted. A surgical product made in accordance with this method is disclosed.
