Abstract: The present invention relates to an assembly for controlling a temperature of at least a part of a person, comprising an esophagus catheter to be inserted into the esophagus of the person for controlling the temperature. The esophagus catheter extends along a longitudinal axis and comprises a proximal heat exchanger defining a first flow direction having a first axial component relative to the longitudinal axis, and a distal heat exchanger defining a second flow direction having a second axial component relative to the longitudinal axis. The esophagus catheter further comprises a plurality of coolant channels each in fluid communication with at least one of the proximal heat exchanger and the distal heat exchanger, and a coolant pump connected or connectable to at least one of the plurality of coolant channels. The assembly is configured to cause simultaneously a coolant flow through the proximal heat exchanger and the distal heat exchanger.

Abstract: The invention relates to a device for selective ventilation of one or both lungs of a patient, comprising an endotracheal tube to be arranged in the trachea of the patient and having a proximal and a distal end, an endobronchial tube connected thereto and having a proximal and a distal end, the distal end of which extends beyond the distal end of the endotracheal tube, and means for positioning by feel the distal end of the endobronchial tube in at least a longitudinal direction of the trachea. The positioning means are herein adapted to also position the distal end of the endobronchial tube in a peripheral direction of the trachea. The positioning means can be arranged close to the distal end of the endobronchial tube and can extend so far outside the periphery thereof during use that they come to lie on the carina of the patient. The positioning means can also be asymmetrical relative to the periphery of the endotracheal and/or endobronchial tube and can be adapted for co-action with the trachea wall.

Abstract: A blood filtering device for the recuperation of blood from wound drained blood, in particular for an autologous blood transfusion system, has a first filter arranged upstream of a second filter. The first filter is adapted for removing emboli and/or large particulate matter from the blood and for allowing red blood cells to pass. The second filter is adapted for retaining red blood cells. An exit port is arranged downstream of the first filter and upstream of the second filter. The device is characterised in that the second filter has a pore size of more than about 0.5 ?m. A method of recuperating blood from wound drained blood is also disclosed.
