Abstract

See full text

A device and method for creating an initial cavity in biological tissue within a given tissue type or layer and then expanding the initial cavity into a larger predetermined final cavity by using a dissecting propagating device to dissect the tissue along a plane defined by the initial cavity. The device and method may also produce the additional effect of immediate or delayed tissue expansion resulting in the production of additional tissue length to facilitate excision or to facilitate geometric rearrangement, advancement, excision or closure during surgical procedures. The expansion effect may relate to the dissected layer or an adjacent layer included in the tissue above, below or around the dissected cavity. The dissection method includes a tunneling step followed by a dissector device introduction step followed by an inflation, expansion, dissection step. The device and method of the present invention can be used to perform skin undermining in the subcutaneous fat layer for facelifting cosmetic surgery.
