Claim Text:
1. A method of forming an implantable device, comprising the steps of: a. Forming a first yarn and a second yarn, wherein at least one of said first yarn and second yarns includes a first non-absorbable filament and at least one of said first yarn and second yarns includes a first absorbable filament, said first absorbable filament having a lower melting point than said first non-absorbable filament, and including the step of kinking at least one of said first absorbable filament and said first non-absorbable filament prior to forming said first or second yarn; b. Forming an initial woven structure comprising said first yarn and second yarn; c. Subjecting said initial woven structure to a first heat treatment at a first temperature sufficient to cause shrinkage of said first absorbable filament, and thus buckling at least the second yarn and forming an initial heated structure; d. Heating said initial heated structure to a second temperature, said second temperature being higher than said first temperature, wherein at least a portion of said first absorbable filament is melted; and e. Allowing said heated structure to cool to form a resulting implantable device.
