Abrégé

A catheter, and preferably a urinary catheter, is disclosed, comprising an elongate shaft with a catheter insertion end and a flared connector connected to the elongated shaft opposite to the catheter insertion end. The flared connector forms a catheter connector end. Further, a gripping sleeve is fixedly connected to the flared connector, and arranged to enclose at least part of, and preferably essentially the whole, flared connector, apart from the catheter connector end. Hereby, a standard catheter can easily be customized for various use situations and users with different needs, in terms of e.g. gripping and manipulation possibilities. A method for producing such a customized catheter is also disclosed.

Abrégé

A medical device is disclosed, comprising a substrate and a hydrophilic surface coating arranged on said substrate. The substrate has, on its surface coated with said hydrophilic surface coating, a surface texture with an arithmetical mean deviation of the surface profile (Ra) of at least 3 μm and/or a profile section height difference (Rdc (1-99%)) of at least 18 μm. It has surprisingly been found that the increased surface roughness of the substrate provides significant improvements in e.g. water retention for the hydrophilic coating.

Abrégé

A method is disclosed for providing a medical device with antibacterial activity, comprising the steps of: providing a substrate material coated with a hydrophilic polymer, said hydrophilic polymer exhibiting a low friction when wetted; providing a colloidal solution comprising chemically reduced particles of an oligodynamic metal and a hydrophilic polymer, said hydrophilic polymer being the same as in the coating of the substrate material; and dipping said substrate material in the solution. A medical device prepared accordingly is also disclosed. By means of this method, very advantageous properties of the antibacterial coating are obtained. In particular, a relatively low release rate is obtained in the wetting fluid, and a relatively high release rate is obtained in the intended use situation, e.g. when inserted into the urethra.

Abrégé

A flushable medical device for short term use, such as a urinary catheter, is disclosed, and also a method for producing such a medical device. The medical device comprises at least an elongate shaft made of a degradable material, the degradability being such that the material becomes essentially totally dissolved if maintained in turbulent water at room temperature for at least 6 hours, but retains its structural integrity in water for at least 5 minutes, and preferably at least 10 minutes. Hereby, the medical device can be used for the intended short term use, and then be flushed in an ordinary toilet after use. The degradable material preferably comprises at least one of monosaccharide, disaccharide, oligosaccharide and polysaccharide. In a preferred embodiment, the degradable material primarily comprises water, at least one of sugar and starch and gelatin.

Abrégé

A coupling device (1) for releasable connection of a medical tubing (2), such as a catheter, is disclosed. The coupling device has no coupling parts being inserted into the lumen of the medical tubing, and is consequently very advantageous for use with medical tubing with soft walls and/or small internal diameters. The coupling device comprises a hollow body member (110) having a first end for receiving an end part of the medical tubing, an opposite second end, for conveying an input or output to said medical tubing, and an intermediate part (113) between said first end and second end, said intermediate part being arranged to accommodate the end part of the medical tubing inserted through said first end and having an inwardly variable diameter. Further, the coupling device comprises a hollow compression sleeve (120) being arrangeable over the intermediate part of the hollow body member.

Abrégé

A bone implant for implantation into bone tissue includes a metallic material having a surface that is covered by an oxide layer wherein the oxide layer has a thickness within the range of from 2 to 100 nm and includes strontium ions homogenously dispersed in the oxide layer. The oxide layer is a metal oxide layer formed from the metallic surface of the implant. The local administration of strontium ions in bone tissue has been found to improve the bone formation and bone mass upon implantation of a bone tissue implant in the bone tissue.

Abrégé

A time and cost effective production method for medical devices with a hydrophilic coating is provided, which ensures adequate adhesion to the substrate, as well as good water retention and low friction properties. Specifically, the method comprises the steps of: providing a substrate;applying, in one or more steps, a coating solution comprising a hydrophilic polymer to a surface of said substrate to form a non-cross linked hydrophilic coating on said substrate; and irradiating the coated substrate, wherein said irradiation is adapted both to cross-link said hydrophilic coating and to simultaneously sterilize the medical device. Hereby, a non-cross linked hydrophilic coating is first obtained on the substrate, which coating is loosely connected to the substrate, and which is not fit for use as a catheter coating. However, after the step of irradiating the coated substrate, the hydrophilic coating becomes cross-linked, and fit for use e.g. on a urinary catheter. Further, since one and the same irradiation step is used to effect both cross-linking and sterilization, the production can be made more efficient, using fewer production steps and with a shortened production time.

Abrégé

There is disclosed a medical device, such as a urinary catheter, comprising a substrate material, a hydrophilic surface coating, e.g. comprising polyvinylpyrrolidone (PVP), arranged on at least a part of the surface of said substrate material, and an antibacterial layer comprising oligodynamic metal arranged between the substrate material and the hydrophilic surface coating. Further, the hydrophilic surface coating has a thickness large enough to provide a controlled release of oligodynamic metal ions through the hydrophilic surface coating, such as a thickness when dry that exceeds 3 μm. Hereby, the variation in the release of the oligodynamic metal ions is significantly reduced, enabling an improved control of the release. A corresponding method is also disclosed.

3. The wetting fluid could either be arranged in contact with the hydrophilic surface layer of the catheter in the receptacle, for preservation of the hydrophilic surface layer in a wetted state during accommodation in said receptacle and provision of a ready-to-use catheter assembly, or be arranged to keep the wetting fluid separated from the hydrophilic surface layer of the catheter during storage, but to be brought into contact with said hydrophilic surface layer upon activation before an intended use of the catheter. A similar method and wetting fluid is disclosed as well. The provision of the osmolality-increasing compound in the wetting fluid provides several advantages per se, such as a improved properties of the hydrophilic coating, a more predictable and controllable wetting process, a more expedient and cost efficient production, etc. Further, the use of this very high concentration of osmolality-increasing compound in the wetting fluid has proven remarkably efficient.
