ABSTRACT:
A combination tissue dissector and long term expander is disclosed for use in plastic surgery applications and other applications where it is desirable to dissect a tissue pocket and serially expand the dissected pocket through long term tissue expansion. The combination device performs the separate functions of dissection and long term expansion in a single balloon package. In an exemplary embodiment, three sheets of substantially inelastic material are bonded together at their outer margins to form two discrete inflatable chambers. The lower inflatable chamber defined by the middle and lower balloon sheets is further welded together at various points over the sheet's surface area to create a semi-rigid base portion which provides a flat well-defined footprint for the balloon. The semi-rigid base prevents further enlargement of the tissue pocket at the margins when the device is utilized as a tissue expander. In a preferred method of use for the combination device, the combination device is tunneled bluntly to a desired location within the body. The device is then inflated to dissect tissue layers along natural tissue planes and create a tissue pocket. After dissection, the combination device may be left within the body as a temporary implant to further expand the tissue pocket through long term expansion until the desired tissue pocket volume is achieved.
