Male straight urinary catheter

Female urinary catheter

Curved flexible male urinary catheter

An intermittent hydrophilic urinary catheter () with a hydrophilic coating () and comprising a plurality of drainage openings () is provided. The outer surface () of the tubular portion () forms a projection () encircling the openings in the outer surface and extending above the hydrophilic surface () when the hydrophilic material is in the non-swelled condition.

Urinary catheter

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

A method of laser welding a layered product comprising two layers () of a high absorption at the radiation wavelength, where one layer () is welded to a material () having a lower absorption and wherein a scattering layer () is provided between the laser welded layers () and the other high absorption layer () in order to scatter any radiation penetrating the first high absorption layer () in order to prevent excessive heating of the other high absorption layer ().

Method of providing a laser welded product and a laser welded product

A method of decreasing the penetration depth of radiation provided to an interface, such as a surface, or a predetermined volume in a polyethylene (PE) element, where the PE element has a scattering coefficient larger than one tenth of an absorption coefficient thereof so that the radiation not absorbed at the interface or in the volume but transmitted further into the PE element is at least partly reflected toward the interface/volume. The radiation intensity is higher in the volume and the absorption coefficient may be reduced while retaining the total absorption in the volume.

Polyethylene product and a method of providing a product, such as a laser welded polyethylene product

An ostomy body side mounting wafer and a method of preparing the ostomy body side mounting wafer, where the wafer is assembled from two parts using laser welding. The laser light is provided through one of the parts having a low or lower absorption of the laser light. The other part has a higher absorption of the laser light, whereby the interface between the two parts is heated at the welding zone(s) of the laser light. In this manner, an assembly is obtained independently of the thicknesses of the materials and even close to openings or other edges.

Ostomy mounting wafer and a method of preparing it

A method for welding together two layers or workpieces within a multi-layer assembly in which laser light is directed through an outer layer of the assembly, allowing transmission of the laser light from its outer surface to at least within the vicinity of its inner surface substantially without any absorption of energy from the laser light. The laser light is directed towards a layer having an absorbent component, corresponding to a portion thereof, capable of absorbing laser light within a given wavelength range thereby creating a welded area between a surface of the layer having the absorbent component and a surface of a layer facing the layer having the absorbent component. The absorbent component can be provided either within the bulk of a layer or it can be provided as a separate surface layer on one or both surfaces of a layer.

Method for welding component of a multi-layer construction

A method welds together two layers within a multi-layer assembly Laser light is directed through an outer layer of the assembly that allows transmission of the laser light from its outer surface to at least within the vicinity of its inner surface substantially without any absorption of energy from the laser light, towards a layer including an absorbent component, corresponding to a portion thereof. The absorbent component is capable of absorbing laser light within a given wavelength range thereby creating a welded area between a surface of the layer having the absorbent component and the surface of a layer facing the layer having the absorbent component while other layers remain unwelded.
