  • METHOD FOR MANUFACTURING A TRIDIMENSIONNAL BLOOD VESSEL
    Publication number: 20220398942
    Abstract: Method for manufacturing a tridimensional blood vessel model using stereolithography and optionally cell culture. Applications include surgery training, research on pathology such as SCDs and in vitro drug testing e.g. for antiplatelets. Existing models are not compatible with cell culture and cannot withstand high pressure, as opposed to the present invention. Stereolithography allows modelling of complex vessels such as carotid siphons as opposed to other existing methods.

  • Submersible apparatus including flexible waterproofing membranes
    Patent number: 8322296
    Abstract: A submersible apparatus (10) which can be fully submerged in a liquid medium, includes: a sealed hollow body (12) having a longitudinal main axis (A); at least one driving member (14, 36, 52) for moving the apparatus (10) horizontally and/or vertically, which can co-operate with the medium in which the apparatus (10) is submerged and which can move in relation to the hollow body (12) through an opening (22, 44, 56) provided in the wall of the body (12); and elements (18, 40, 64) for actuating the driving member (14, 36, 52), which are disposed inside the hollow body (12). The invention is characterized in that the opening (22, 44, 56) is sealed by a flexible membrane (24, 50, 58) which can deform and co-operate with the driving member (14, 36, 52) as the driving member (14, 36, 52) moves through the opening in order to move the apparatus (10).
