Method and device for microdialysis sampling
First Claim
1. Microdialysis sampling method utilizing at least one microdialysis probe (1) placed on the surface of a vital human or animal organ for sampling metabolic substances that indicate the metabolic conditions of the organ from the surface of the organ characterized by that the probe (1) is temporarily attached to the outside surface of the vital organ by at least one suture and not inserted into the substance of the vital organ, samples said metabolic substances via a semi-permeable membrane (9) attached to the probe (1), the side facing the surface of the organ.

Abstract
Microdialysis sampling methods utilizing at least one microdialysis probe placed on the surface of a vital human or animal organ for sampling metabolic substances that indicate the metabolic conditions of the organ from the surface of the organ. The invention further relates to microdialysis sampling probes for sampling metabolic substances, said probes being adapted to be attached to the surface of a vital human or animal organ.

- 3. Microdialysis sampling probe (1) for sampling metabolic substances via a semi-permeable membrane (9) attached to the probe (1), comprised of an outer casing (2) with an inlet (3) and an outlet (4) connected by a channel (5) that allows perfusion fluid to flow through the probe (1), characterized by that on the end or tip of the probe (1) opposite the inlet (3) and outlet (4) is placed a ring (8) designed for temporarily securing the probe to a vital organ via at least one suture.
- 7. Microdialysis sampling probe (1) for sampling metabolic substances via a semi-permeable membrane (9) attached to the probe (1), comprised of an outer casing (2) with an inlet (3) and an outlet (4) connected by a channel (5) that allows perfusion fluid to flow through the probe (1), characterized by that the side of the permeable membrane (9) intended to be facing away from the organ is covered so as to reduce evaporation and possible interface or contact with other organs and further characterized by that on the end or tip of the probe (1) opposite the inlet (3) and outlet (4) is placed a ring (8) designed for temporarily securing the probe to an organ via at least one suture.
