Tissue expanders and their methods of use.

主权项

1. A method of expanding breast tissue, comprising:
positioning an external device external to a patient and proximate the patient's breast; actuating the external device to wirelessly transmit a signal from the external device to a self-contained tissue expansion device, wherein the tissue expansion device comprises a compressed gas source disposed completely within and in fluidic communication with a compartment comprising an inelastic material with a preformed breast shape, the preformed breast shape having an inferior portion that extends more in an anterior direction than a superior portion, and wherein the compartment is disposed within the patient's breast; wherein actuating the external device controllably releases gas from the compressed gas source into the compartment to controllably inflate the compartment and cause the inelastic material to be reconfigured towards its preformed shape with the inferior portion that extends more in an anterior direction than a superior portion; and stimulating new tissue growth adjacent the tissue expansion device.
