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]. 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.

Microdialysis catheter

Although this prior microdialysis catheter represents a major step forward in the art of microdialysis, it still suffers from the main drawback of all prior art microdialysis catheters, viz. a low ratio of area to volume, i.e. the effective area of the membrane in relation to the volume of dialysis solution passing the membrane per unit of time. The Effect of Microdialysis Catheter Insertion on Glutamate and Serotonin Levels in Masseter Muscle in Patients with Myofascial Temporomandibular Disorders and Healthy Controls Bajramaj, Ermira Malmo Univ, Sweden.

2 Mar 2011 The extraction ratio of this catheter and perfusion rate is known to be close to 70 % [23]. MD catheters were viewed on CT scans with the

MD catheters were viewed on CT scans with the This indicates that it is advisable to place a second microdialysis catheter in the subcutaneous cellular tissue as a guide in assessing the changes in metabolites The microdialysis technique requires the insertion of a small microdialysis catheter or microdialysis probe into the tissue of interest. The microdialysis probe is High quality, reliable probes with a worldclass reputation for microdialysis Accessories to be used with the CMA microdialysis probes and instruments. The sterile, single use 71 High Cut-Off Brain Microdialysis Catheter is minimally invasive and designed for implantation in brain tissue. The most important The brain tissue oxygen tension (Ptio2) probe was located anterior to the intracerebral prssure (ICP) probe.

The 66 Linear Microdialysis Catheter is a minimally invasive sterile single use device intended for Microdialysis monitoring in skin, adipose or resting skeletal muscle tissue. It has a new robust design with a high performance membrane. The catheter is available with 20,000 or 100,000 Daltons cut off membrane.

The catheter is easily introduced into the tissue with a splitable introducer and can be implanted for several days. The microdialysis technique requires the insertion of a small microdialysis catheter (also referred to as 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. The 66 Linear Microdialysis Catheter is a minimally invasive sterile single use device intended for Microdialysis monitoring in skin, adipose or resting skeletal muscle tissue. It has a new robust design with a high performance membrane. The catheter is available with 20,000 or 100,000 Daltons cut off membrane.

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.

Haugaa H, Thorgersen EB, Pharo A, Boberg KM, Foss A, Line PD, Sanengen T, Almaas R, Grindheim G, Waelgaard L, Pischke SE, Mollnes TE, Tønnessen TI: Inflammatory markers sampled by microdialysis catheters distinguish rejection from ischemia in

Solna, Sweden) catheters 14G, triple lumen, 5000 Da cutoff. The mi - crodialysis 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 (Figure1). The microdialysis catheter uses a 0.9% NaCl In the sterile microdialysis catheters, the direction of ﬂow is often the opposite in order to minimize the dead volume between the membrane and the collec- tion microvial. The “dialysis”, i.e.
