Abstract
A downhole tool includes an improved expandable, elastomeric component having a pre-disposed expansion profile. The expansion profile is pre-disposed by surrounding at least a portion of the elastomeric component with a shaping tool having an inner diameter that defines a profiled limit. Fluid under pressure is applied to the elastomeric component for expanding it into contact with the inner diameter of the shaping tool. The pressure of the fluid may be reduced to allow the elastomeric component to return generally to its original shape.
