Abstract
A pressure monitor for use in connection with tissue expander envelopes implanted beneath the tissue of the skin wherein a liquid is injected into the envelope to cause expansion of the skin or tissue and additional liquid is periodically injected to cause progressively increased expansion of the tissue. The tissue monitor includes means extablishing direct communication between the pressure monitor and the liquid injected under pressure whereby the monitor will provide a reading of the internal liquid pressure in the envelope. The method comprises the steps of implanting an inflatable envelope beneath the skin, injecting a sterile solution under pressure through a fill line communicating with the envelope, interrupting the flow of liquid under pressure into the envelope, sensing the pressure level of liquid injected into the envelope, and adjusting the pressure level when necessary either by removing from or injecting liquid into the envelope.
