Abstract:
1. A method of performing plastic surgery operations using a surgical thread having a clear section and multiple sharp projections on either side of the clear section, wherein the clear section is devoid of projections, and the projections on both sides of the clear section are inclined toward the clear section, the method including: making an incision into tissue at an entry point defining the point of tissue lift; inserting a cannula in a first pass subcutaneously between the entry point and a first exit point from where tissue is to be suspended; threading one end of the surgical thread from the entry point through the cannula and out of the first exit point until the clear section nears or enters the incision; removing the cannula and reinserting the cannula in a second pass between the entry point and a second exit point spaced from the first exit point; threading the other end of the surgical thread through the cannula and out of the second exit point thereby folding the thread back on itself to form a loop or sling; removing the cannula and adjusting the thread tension from both ends of the thread to achieve a desired lift along a direction from the point of tissue lift toward the first and second exit points, the projections resisting thread pull in the direction of the entry point and the clear section being located at the fold; cutting the thread ends; and closing the incision at the entry point.
