GRAVITATIONAL HEART PERFUSION SYSTEMS FOR THE LANGENDORFF EXAMINATION OF SMALL MAMMAL HEARTS WITH WORKING HEART OPTION The advantage of the gravitational product line is that the constant pressure – by the continuous replacement of the saline – can be sustained in a stable way. Another key advantage is that by inserting a proper peristaltic pump, the constant flow mode can be easily configured. The systems are produced in one- and two-channel designs (LS-01G, LS-02G) including the Janicki-type working heart option, by default. Any basic model can be upgraded with the Neely-type working...

LS-01G ONE-COLUMN AND LS-02G TWO-COLUMN LANGENDORFF The flowchart of the LS-02G two-column system illustrates the operating principle, which is identical with the LS-01G one-column system. The advantage of the LS-02G is that two material impacts can be examined on the preparation simultaneously. Langedorff heart suspending unit and cannula We tried to develop a heart suspending unit, where the preparation can be placed on cannula quickly and without damage. The end of the cannula is notched, which supports the method of placement and the positioning of the binding thread. Taking the weight...

LS-03GN NEELY-TYPE WORKING HEART OPTION The biggest advantage of the new system is that – unlike any other system on the market- no new device is necessary, even if you wish to expand the methodological background with the Neely option. If you have any pump-controlled Langendorff system (LS-01G, LS-02G) you only need to purchase the Neely option and the heart suspending unit for the methodology. Langedorff-Neely heart suspending unit and cannula The Neely option has all the advantages, which we highlighted at the Langendorff heart chamber. A further advantage is the specially designed...

Extra-/intracellular MAP measurement, stimulation Eight-point extracellular MAP measurement The system allows one-point extra-/Intracellular MAP measurement and stimulation, built in a 3600 adjustable ball manipulator. The manipulator can be organically connected to the system. The eight-point non-invasive measurement is a unique development of our company. The preparation is placed in an organ bath filled with saline solution, surrounded by the MAP sensor. The sensors detect the MAP signals through the solution, which are detected by a specially designed biological amplifier. Saline...

PUMP-CONTROLLED HEART PERFUSION SYSTEMS FOR THE LANGENDORFF EXAMINATION OF SMALL MAMMAL HEARTS WITH WORKING HEART OPTION This product line is the latest development of our company, which can be easily placed even in a laboratory with limited place. For the development we used established technical solutions and the experience of the previous years. The systems are made in one- and two-column design (LS-04P, LS-05P) and the Neely-type working heart option (LF-06PN) can be added to any basic setup. The constant pressure and flow rate precision pump is controlled by the amplifier-operated...
