kate - Telecom null for gruel condition thrombus removal

摘要

PURPOSE:To make it possible to remove the porridge-like thrombus in a blood vessel without losing much blood by providing the above catheter with a first catheter which is closed at the front end has a first balloon and a second catheter which has a second balloon disposed at the outside wall of the vessel parted from the position of the first balloon and is movable forward and backward. CONSTITUTION:The front end 4 of the catheter is introduced into the blood vessel from the downstream side in the blood vessel in the state of shrinking the first and second balloons 2, 3 and the second balloon 3 is arranged in the thrombus position in the case of removing of the porridge-like thrombus. Pressurized fluid is then introduced from a first inflow port 10 of the first catheter 7 communicated with the first balloon 2 extending from the rear end of the catheter to expand the first balloon 2 and to shut off the blood. The pressurized fluid is thereafter introduced from a second pressurized fluid introducing pipe 6 communicated with the second balloon 3 into the second balloon 3 to expand this balloon and to move the second catheter 8 backward, by which the second balloon 3 is slid on the inside wall of the blood vessel and the porridge-like thrombus is removed.
