Abstract
A method of manufacturing a microdialysis catheter, comprises the steps of extruding a flexible material to form an elongate catheter body having a substantially cylindrical outer surface and a plurality of continuous internal channels extending in the longitudinal direction of said catheter body; sealing a free end of said catheter body; providing in said surface at a distance from said free end an opening extending into said catheter body to communicate with a portion of a first of said channels; providing communication between said first channel and a second of said channels at a distance from said free end shorter that said distance; and covering said opening by a microdialysis membrane.
