A method, a kit and an applicator for performing a surgical occlusion. A tubular applicator open at both ends is introduced with a first end adjacent a free-prepared tissue. At least one bundle-strap type tie is introduced into the applicator. A tie portion protruding from said first end of the applicator is caught in order to position the tie in its proper place around the tissue. Thereafter, the tie is formed into a locked occlusion loop around said tissue. The occlusion technique is applicable to both laparotomy and laparoscopy.
