  • High stretch, low dilation knit prosthetic device and method for making the same
    Patent number: 7364587
    Abstract: A method for providing dilation resistance to an implantable tubular graft includes the steps of (a) providing a graft having opposed open ends and a textile wall extending in a lengthwise direction therebetween defining a graft diameter, wherein the textile wall has radially extending yarns having a radial extent which inter-engage longitudinally extending yarns having a longitudinal extent to define a textile pattern and further wherein the radially extending yarns are obliquely oriented to the lengthwise direction of the graft, thereby defining a first acute angle from the lengthwise direction of the graft; (b) providing an elongate tubular mandrel having a diameter which differs from the graft diameter by a factor of at least 1.
