[Mechanical properties of a new vena cava filter].
The construction and the mechanical properties of a percutaneous, transvenous implantable thrombus filter on the pulmonary embolism prophylaxis is introduced. The pressure loss by this filter amounted to nearly 1/60 in comparison with the Mobin-Uddin umbrella filter. The effect of partial occlusions by thrombus is estimated theoretically by means of technical models. The anchoring of the fresh implanted filter is guaranteed in case of embolisation with covering up to 85% of the open surface. A much faster anchoring is to be expected by reaction of the tissue after few days. It also resists in the most unfavourable case imaginable.
