  • the guide rail 7 extends over the full length of the housing 2, so allowing blood vessels with varying lengths to be attached.
  • the device 1 is especially suitable for use with the following types of tissue: 1) tissue comprising a cavity in which, in vivo, an internal pressure prevails, or 2) tissue that, in vivo, is run through by a fluid.
  • tissue of the first category are lungs, stomach, (gall)bladder etc.
  • tissue of the second category are blood vessels, lymphatic vessels, urinary passages, Fallopian tubes etc.
  • Fluid supply pipes 11 are, preferably detachably, attached to the housing 2, for instance by means of detachable blocks 6.
  • the fluid supply pipes 11 are connected to the hollow tubes 4 in order to establish the desired internal pressure in any cavity of the tissue and/or allowing a fluid flow through any cavity of the tissue, by means of any kind of fluid suitable.
  • the drainage of fluid present in the hollow space is provided for by drainage pipes 12.
  • the fluid drainage pipes 12 are provided with stopcocks 13 which can be used to create any desired level of fluid in the hollow space 3 in order to simulate in vivo operating conditions.
