Abstract: A thrombus-mobilizing thoracostomy tube includes fenestrations to enable drainage when introduced into a thoracic cavity, the tube including a balloon which may be inflated to dislodge and move blood clots, the balloon being connected to a first tube to enable a suitable fluid to be introduced to inflate the balloon progressively from a distal end to a proximal end, and a second tube parallel to said first tube to enable the introduction of a flushing fluid into the thoracostomy tube, whereby blood clots may be dislodged and removed from the thoracostomy tube without removing any portion of the thoracostomy tube from the user's body, thereby substantially reducing the risk of contamination while maintaining sterile conditions. The flushing fluid may include a heparin solution, a saline solution, a heparinized saline fluid, or a urokinase fluid.

Abstract: A tool suitable for borehole logging, including production oilwell borehole logging, contains a radioisotope neutron source (14), a fast neutron detector (15) and a gamma-ray detector (16). Gamma-ray detection events are selected for building spectra by coincidence or anticoincidence with detection of the associated neutron. In a development, additional information is derived from identification of which of a series of time intervals encompasses detection of a neutron after detection of a gamma-ray.
