Equipment and methods for ultrasonic sealing of removable sutures and iudal implant systems including removable sutures

Abstract

The invention relates to an ultrasonic welding apparatus (1) of a magnetic field (2) in one aspect. This apparatus includes a welding mold (3) including a welding groove (4), the welding groove having length Lg, width Wg and depth Dg and bottom (5) having a concave shape. This apparatus also includes a welding electrode (6) having length Ls which is 150-220% of Lg, width Ws of the welding tip (7) of the welding electrode which is 80-98% of Wg and depth Ds. In addition, the welding tip of the welding electrode has a concave shape.
