摘要

This invention relates to an implantable, multiple envelope tissue expander and to a method of using the same to produce a flap or section of tissue having a preselected shaped for use in plastic surgical procedures. The device consists essentially of at least two separately inflatable envelopes wherein one is used as a base and is fixed to body members underlying the tissue to be expanded. The other envelope is smaller in volume than the first and is attached to the upper half of the base envelope to expand the tissue overlying the second envelope to a greater extent than is accomplished by the first envelope to thereby produce a section of tissue with a preselected shape.
