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: The present invention relates to hydroxyalkyl starch or a pharmaceutical preparation thereof for the treatment of head and neck cancer, especially by effectively reducing tumor growth rate and inhibiting tumor growth and wherein the hydroxyalkyl starch has a mean molecular weight (MW) above 20 and below 1300 kDa and a molar substitution (MS) in the range of from 0.1 to 1.5, wherein the alkylation may be an ethylation, propylation or butylation or mixes thereof; and wherein the alkyl may be further substituted.
