Claim:
A method of making an implant envelope, comprising the steps of: a) selecting a mandrel; b) selecting a dispersion into which the mandrel is dipped; c) fully submerging the mandrel in the dispersion, withdrawing the mandrel from the dispersion and thereby picking up a first envelope layer on the mandrel, and permitting the first envelope layer to at least partially stabilize; and d) partially submerging the mandrel in the dispersion, withdrawing the mandrel from the dispersion and thereby picking up a second envelope layer on the mandrel and permitting the second envelope layer to at least partially stabilize, such that a first envelope coating of a first thickness is disposed over one portion of the mandrel and a second an envelope coating of a second thickness is disposed over another portion of the mandrel and wherein the first and second envelope coatings form the implant envelope.
