Abstract
An ultrasonic clamp coagulator assembly embodying the principles of the present invention is configured to permit selective cutting, coagulation, and clamping of tissue during surgical procedures. In an ultrasonic blade according to the present invention, the blade is constructed such that the cross-sectional area of the blade is smaller at the proximal end of the compression zone than at the distal end. This performance-enhancing feature creates a more consistent cutting and coagulation of the tissue along the length of the blade reducing the time the blade is in operation and reducing overall heat generation.
