Abstract: A port cannula for puncturing implantable or implanted port catheters includes a cannula tube with a ground surface, which is formed from a ground cut inclined with respect to a center axis of the cannula tube by a ground-cut angle and from two facet cuts lying at an angle to each other, and of a cannula tip which is provided by the ground surface and which is oriented via a first bend in the direction of the center axis of the cannula tube. The ground cut and the facet cut are adapted to each other in such a way that, on the one hand, during puncturing, a bending of the cannula is least reduced and, on the other hand, the pain caused to the patient is kept within an acceptable range.

Abstract: A method for the sterile connection of pipes, consisting of: providing a first and a second pipe; a separating area of the first and second pipes is heated; both pipes are mechanically separated by exerting traction and/or shear force onto the pipes so that both pipes are respectively separated in the heated separating area; after the pipes are separated, a mechanical contact between the end of the first pipe section of the first pipe formed by the separation of the first pipe is established with the end of the first pipe section of the second pipe, formed by the separation of the second pipe, and mechanical contact is established such that the ends of the pipe sections still have, following heating when they come into mechanical contact with each other, a temperature such that they form a material fit connection without additional heating after separation.
Abstract: The invention relates to a method for coupling low-molecular weight substances to a starch-derived modified polysaccharide. The binding interaction between the modified polysaccharide and the low-molecular weight substance is based on a covalent bond which is the result of a coupling reaction between the terminal aldehyde group or a functional group of the modified polysaccharide molecule resulting from the chemical reaction of this aldehyde group and a functional group of the low-molecular weight substance which reacts with this aldehyde group or with the resulting functional group of the polysaccharide molecule. The bond directly resulting from the coupling reaction can be optionally modified by a further reaction to the aforementioned covalent bond. The invention further relates to pharmaceutical compositions that comprise conjugates formed in this coupling process and to the use of said conjugates and compositions for the prophylaxis or therapy of the human or animal body.
