Catheter With Microchannels For Monitoring The Concentration Of An Analyte In A Bodily Fluid

摘要

Catheter for monitoring the concentration of an analyte in a body fluid having an implantable distal area ( 7 ) for the uptake of body fluids and a proximal area ( 8 ) with an outlet opening ( 14 ), wherein the catheter comprises a catheter casing ( 1 ) having microopenings which are permeable to at least part of the body fluid and at least partially hold back corpuscular components, and a catheter core ( 2 ) which is located in the catheter casing ( 1 ). The catheter core preferably has a microstructure on its peripheral surface and/or the catheter casing has a microstructure on its inner wall which form a hollow space between the catheter core and catheter casing. Moreover the invention concerns a method for the manufacture of such a catheter.
