Temporal Brow Lifting and Fixation Device

Abstract

The present invention describes an implantable tissue lifting and fixation device. More particularly, the present invention describes a temporal brow lifting device comprises of a bio-absorbable supportive backing. The device has a shape of a curvilinear end and a tail end region. The curvilinear end region comprises a plurality of attachment points protruding from the supportive backing, and the tail region comprises of a plurality of cavities in order to secure the device at the desired elevated position in the deep temporal fascia.
