The Microdialysis Catheter mimics a "blood capillary". There is an exchange of substances via extracellular fluid The Microdialysis membrane: Chemical substances from the extracellular fluid diffuse through the dialysis membrane and are carried out of the catheter by a flow of Perfusion Fluid to a microvial.

The “dialysis”, i.e. the diffusion of molecules between the extracellular ﬂuid and the perfusion ﬂuid, takes place while the perfusion ﬂuid passes the microdialysis concept as an efficient clinical method for measuring blood glucose and lactate levels. In Study II, the outlet of the compartment of the microdialysis catheter was directly connected to a recently developed sensor, continuously analyzing glucose and lactate concentrations of the dialysate fluid. implantation of two microdialysis catheters along the biopsy trajectory, one into the contrast enhancing tumour tissue and one into the brain adjacent to tumour (BAT) region (Figure 1).

In 105 of these patients one, two or three additional catheters were inserted into the ipsi- or contralateral hemisphere (Table 1).

A double-lumen microdialysis catheter with a dialysis membrane at the end is introduced into the tissue. Dialysate is slowly pumped through the catheter and will equilibrate with the surrounding extracellular matrix. CMA Microdialysis AB Torshamnsgatan 30A, SE-164 40 Kista, Sweden Tel: +46 8 470 10 00 E-mail: cma@microdialysis.se Microdialysis is a well-established technique that allows the sampling of neurotransmitters and algesic substances, as well as the monitoring of time-dependent changes in speciﬁc tissue [9,10,13].

The microdialysis probe is designed to mimic a blood capillary and consists of a shaft with a semipermeable hollow fiber membrane at its tip, which is connected to inlet and outlet tubing. The microdialysis catheter was inserted in the subcutaneous adipose tissue of the patients in order to measure the glucose concentration in the interstitial fluid continuously. The catheter was perfused with a pump rate of 0.3 microL/min. For method comparison capillary blood glucose measurements were performed as reference values. The 70 Microdialysis Bolt Catheter is designed for implantation in brain tissue through the IM2 Bolt kit for 2 brain probes or the IM3 Bolt Kit for 3 brain probes from Integra. The catheter has a 130 mm long shaft and a membrane length of 10 mm. The shaft has a reinforced stainless steel section measuring 16.5 mm in length.

Our product line includes a broad range of microdialysis probes, pumps, fraction collectors and associated accessory products to assemble complete systems for demanding research applications. Microdialysis sampling was initiated directly post-surgery and microdialysis vials were changed every two hours. The catheters were perfused with a commercially available 5% Human Albumin in a water solution containing the excipients sodium chloride, N-acetyl-DL-tryptophan and caprylic acid (Albunorm, Octapharma, Stockholm, Sweden), at a rate of 0.3 μL/min.

In some experimental and clinical setups, the microdialysis catheter is subjected to external pressure, av C Hage · 2012 — The accuracy of an intravenously inserted microdialysis catheter intended for continuous glucose moni- toring was validated in 14 patients in a CCU setting.

The catheter has an elongate catheter body including a first channel for supplying a first fluid and a second channel for returning said first fluid. The microdialysis catheter acts as an artificial blood capillary and the concentration of substrate in the collected fluid (microdialysate) is related to the balance between substrate delivery to, and uptake or excretion from, the extracellular fluid. A MD catheter consists of a fine double lumen probe, lined at its tip with a semi-permeable dialysis membrane. The probe tip is placed into biological tissue and perfused via an inlet tube with fluid isotonic to the tissue interstitium.
