The sterile, single use 61 Microdialysis Catheter and the 61 High Cut-Off Microdialysis Catheter are intended to enable microdialysis in the hepatic tissue or in the intraperitoneal cavity.
The 61 MD catheter has a membrane with 20,000 Dalton cut off and the 61 High Cut-Off MD Catheter has a 100,000 Dalton cut off membrane.

Both the 61 MD Catheter & 61 High Cut-Off MD Catheter have a shaft length of 310 mm and a membrane length of 30 mm. The catheter is first introduced by the surgeon via a tunnelating needle through the abdominal wall during open surgery.
-When placed into the liver tissue it is achieved with the help of a splitable introducer and after insertion it is secured to the liver by sutures to the falciform ligament.
-For intraperitonally use it is placed free floating in the intraperitoneal cavity close to the intestinal anastomosis or the region of interest.

A unique monitoring system

The 61 MD Catheter and the Microdialysis Pump forms a complete system with the ISCUSflex Microdialysis Analyzer. Microdialysis offers a unique opportunity to monitor the metabolism of the liver or the intraperitoneal cavity for several days. The samples can be analyzed in the ISCUSflex Microdilaysis Analyzer for Glucose, Lactate, Pyruvate, Glycerol, Glutamate and Urea or sent to the laboratory for further analysis.

When using the 61 High Cut-Off MD Catheter we recommend perfusing the catheter with perfusion fluid containing high molecular weight substances for fluid balance and to avoid ultrafiltration (eg. Dextran or equivalent).

  • Monitor Hepatic tissue or Intraperitoneal

  • Available with 20 000 or 100 000 Dalton membrane cut off
