Abstract
An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.
Claims17
An apparatus, comprising:
- an ultrasonic surgical blade for at least one of cutting and coagulating tissue, wherein the ultrasonic surgical blade comprises:
- a body having a proximal end, a distal end, and an outer surface comprising a treatment region configured to directly contact the tissue to be treated, wherein the distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end;
- and
- a lubricious coating for contacting tissue, wherein the lubricious coating comprises a coefficient of friction that is less than the coefficient of friction of the outer surface of the body, wherein the lubricious coating is adhered to at least a portion of the treatment region of the outer surface of the body, and wherein the lubricious coating comprises a polymeric material.

An apparatus, comprising:
- an ultrasonic surgical blade for at least one of cutting and coagulating tissue, wherein the ultrasonic surgical blade comprises:
- a curved body having a proximal end, a distal end, an outer surface, and a longitudinal axis defined between the proximal end and the distal end of the curved body, wherein the longitudinal axis defines at least one curve, and wherein the distal end is movable relative to the longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end, and wherein the outer surface comprises a treatment region configured to directly contact the tissue to be treated;
- and
- a lubricious coating having a coefficient of friction that is less than the coefficient of friction of the outer surface of the curved body, wherein the lubricious coating is adhered to at least a portion of the treatment region of the outer surface of the curved body, and wherein the lubricious coating comprises a polymeric material.

An apparatus, comprising:
- an ultrasonic blade structured to coagulate and cut tissue, the ultrasonic blade comprising:
- a proximal end;
- a distal end movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end;
- an outer surface comprising a tissue treatment region configured to directly contact the tissue to be treated;
- a surface treatment applied to at least a portion of the tissue treatment region;
- and
- a lubricious coating applied over at least a portion of the surface treatment, wherein the lubricious coating comprises a coefficient of friction that is less than the coefficient of friction of the outer surface, wherein the surface treatment is configured to enhance adhesion of the lubricious coating to the outer surface, and wherein the lubricious coating comprises a polymeric material.
