Abstract:
An elastomerically recoverable PTFE material is provided including a longitudinally compressed fibrils of ePTFE material penetrated by elastomeric material within the pores defining the elastomeric matrix. The elastomeric matrix and the compressed fibrils cooperatively expand and recover without plastic deformation of the ePTFE material. The material may be used for various prosthesis, such as a vascular a prosthesis like a patch, a graft and an implantable tubular stent. Further, a method of producing the elastomerically recoverable PTFE material is provided herein.
