A suction catheter system for drawing off thrombi and emboli from blood vessels has a central catheter and an outer catheter which coaxially surrounds the latter. For introducing the catheter system into a vessel and for widening the said vessel, a guide wire and a dilator are provided. A blood clot is removed by means of a vacuum which is applied to the central catheter. Should the central catheter become blocked by the blood clot as the latter is drawn off, the central catheter can be withdrawn from the outer catheter and can be replaced by a new central catheter. This new central catheter can be connected to the suction device and the procedure continued. Instead of introducing a new central catheter, the suction procedure can also be continued via the outer catheter by means of the latter being connected to the suction device after the central catheter has been removed.
L'invention porte sur un système de cathéter de succion permettant d'aspirer les thrombi et emboles des vaisseaux sanguins. Le système comporte un cathéter central et un cathéter externe qui entoure le premier de façon coaxiale. Il comprend également un fil-guide et un dilatateur pour introduire le système de cathéter dans un vaisseau et pour élargir ce dernier. Un caillot de sang est retiré au moyen d'une aspiration appliquée au cathéter central. Ce dernier peut être retiré du cathéter externe et remplacé par un nouveau cathéter central si le caillot vient à le bloquer pendant l'aspiration. Donc, ce nouveau cathéter central peut être raccordé au dispositif de succion afin de poursuivre l'intervention. Au lieu d'introduire un nouveau cathéter central, l'intervention de succion peut également se poursuivre par le biais du cathéter externe qui est relié au dispositif de succion une fois le cathéter central retiré.
