Energy induced bulking and buttressing of tissues for incontinence
View Patent ↗Methods, devices, and systems for treating the support structures of the body, particularly for incontinence, take advantage of two mechanisms to enhance the support provided by the fascia, ligaments and tendons: first, the invention increases a modulus of elasticity of these tissues, and particularly of the fascial tissues. The increase in modulus can be effected by directing sufficient energy to the fascial tissue so as to promote the formation of scar tissue. The second mechanism attaches tissue planes together, often by directing energy to an interface between adjacent fascial tissues.
