The present invention is directed to a suturing device comprising: a body member having a proximal end, a distal end, and a longitudinal axis positioned between the proximal and distal ends, the body member comprising a slide and a trigger slide; a tip assembly attached to the distal end of the body member and comprising: a hollow sheath having a distal end and a window positioned at the distal end; a pushrod housed in the hollow sheath, the pushrod being in mechanical communication with the slide and moveable along the longitudinal axis; and a heating element sheath containing a heating element, the heating element sheath positioned adjacent to the hollow sheath, the heating element in mechanical and electrical communication with the trigger slide, the heating element moveable within the heating element sheath and along the longitudinal axis and over the window; circuitry in electrical communication between the trigger slide and the heating element, wherein the trigger slide activates the circuitry to heat the heating element and moves the movable heating element along the longitudinal axis and over the window to contact a suture and thereby create a bloom of suture material. The present invention is also directed to suturing techniques using the above device.
