A microdialysis probe and catheter arrangement includes a catheter carrying in a distal end thereof a probe to be inserted in the body of a living being. 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.

It consists of a thin, semi-permeable catheter that mimics a blood vessel, which is inserted in the tissue. The catheter is infused with a perfusate by a The microdialysis technique requires the insertion of a small microdialysis catheter or microdialysis probe into the tissue of interest. 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. Sterile, single use Microdialysis Catheter intended for use in Adipose tissue, resting skeletal muscle tissue and in Hepatic tissue during open surgery. Read more. Clinical Microdialysis, Clinical Microdialysis Catheters. Cerebral microdialysis involves placement of a small catheter with a semipermeable membrane in the parenchyma of the brain, so that a dialysate fluid can be instilled into the catheter, allowed to equilibrate and withdrawn for analysis (Figure 20-1).
In clinical practice the most commonly used system comprises a catheter that is 10 mm in length with a 20 kDa (CMA 70, CMA/Microdialysis) or 100 kDa (CMA 71, CMA/Microdialysis) molecular weight cut-off, perfused with commercially available perfusate solution (Perfusion Fluid CNS, CMA/Microdialysis) at a rate of 0.3 µl min −1. The microdialysis function was not affected when the catheter was used for infusions and drug administration, since the dialysis membrane is physically separated from and located “upstream” relative to the catheter tip (Figure 1). The microdialysis catheter uses a 0.9% NaCl carrier fluid as perfusate with a continuous flow of 5 μL/min.8 The Effect of Microdialysis Catheter Insertion on Glutamate and Serotonin Levels in Masseter Muscle in Patients with Myofascial Temporomandibular Disorders and Healthy Controls DSpace Repository JavaScript is disabled for your browser. Microdialysis was carried out in 15 patients with TMD and 15 controls, and samples were collected every 20 min during a period of 140 min.
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.
In four patients (3% of implanted catheters), follow-up computed tomography (CT) scans showed a small intracerebral blood collection (always The microdialysis process. The technique involves a fine catheter lined with a membrane being placed into the brain tissue to monitor neurotransmitters, peptides

The OneSenz on-line lactate analyzer, (Senzime AB (publ)) was connected with a microdialysis catheter via a standard peripheral vein catheter
Microdialysis can be used to detect tissue ischemia. 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. A MD catheter consists of a fine double lumen probe, lined at its tip with a semi-permeable dialysis membrane.

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]. It consists of a thin, semi-permeable catheter that mimics a blood vessel, which is inserted in the tissue.
