RETROGRADE CORONARY SINUS CATHETER |
摘要 |
A coronary sinus catheter (12> for the retrograde infusion of cardioplegia solutions into the coronary sinus. The catheter (12> is adapted for improved retention in the coronary sinus. The catheter (12) comprises a catheter tube (18) having infusion, pressure-sensing and balloon-inflation lumens, an inflatable balloon (16) and a pressure sensor tube (24) in fluid communication with the balloon-inflation lumen for sensing pressure in the inflatable balloon (16). The internal volume of the pressure sensor tube (24) is relatively non-expansible relative to the internal volume of the inflation balloon (16) in normal operation of the catheter (12). Other aspects of the invention include a constricted portion in the infusion lumen that is believed to eliminate spraying of fluid through the infusion lumen outlet(s) (34), and a temperature sensor strip (74) providing a display on the catheter (12) of the temperature of the infused fluid. <IMAGE> |
