A tubular vascular graft is attached to a rigid tubular portion of an implantable prosthetic device by assembling the vascular graft plus a surrounding heat-shrinkable polymeric sleeve on the rigid tubular portion. The polymeric sleeve, which may be TEFLON-FEP, extends a short distance past the free end of the tube and upon heating shrinks into firm compressive contact with the vascular graft and provides a smooth transition in stiffness between the end of the rigid tube and the soft, flexible graft.
