    摘要： A method for manufacturing an elongated element (200) is provided. The method comprises arranging a molding cavity (101), defined by a mold (103) and a mold insert (104), said mold insert (104) comprising a mold core (105) and a displaceable mold cavity wall (106), said displaceable mold cavity wall (106) being arranged between the mold (103) and the mold core (105), such that the molding cavity has a start volume in a start position of the displaceable mold cavity wall (106). Then a liquid material is injected into a proximal end (102) of the molding cavity (101), where after the displaceable mold cavity wall (106) is displaced in relation to and along with the mold (103) and the mold core (105), distally during said injection, to increase the molding cavity volume from the start volume into an end volume at an end position of the displaceable mold cavity wall (106), wherein the molding cavity (101) in said end position of the displaceable mold cavity wall (106) corresponds to the elongated element (200). The liquid material is solidified, such that the elongated element (200) is formed, and the elongated element (200) and mold insert (104) is removed from said mold (103), where after the elongated element (200) is removed from said mold insert (104). An elongated element and a mold assembly for the manufacture thereof are also provided.

    摘要： A method of preparing a wound dressing includes coating a support layer with an adhesive layer and forming a pattern of depressions in the adhesive layer on an edge portion of the wound dressing, with the pattern of depressions being in the adhesive layer and not penetrating the support layer. The method includes forming a plurality of through-going holes in a central portion of the wound dressing, with the through-going holes penetrating both the support layer and the adhesive layer and each of the plurality of through-going holes at least as large in the support layer as in the adhesive layer.
