Embodiment approach

[0030] [overall composition]

[0031] figure 1 It is a schematic block diagram of an example of the overall configuration of a catheter system (catheter system 5 ) according to an embodiment of the present invention. The catheter system 5 is used for treating arrhythmia of a patient (patient 9 in this example), and includes an ablation catheter 1 , a liquid supply device 2 , a power supply device 3 , and a counter plate 4 . That is, in the catheter system 5 of the present embodiment, the liquid supply device 2 and the power supply device 3 are configured separately.

[0032] (ablation catheter 1)

[0033] The ablation catheter 1 is an electrode catheter that is inserted into the body of the patient 9 through a blood vessel to ablate an affected part to treat arrhythmia and the like. The ablation catheter 1 also has an irrigation mechanism for causing a predetermined irrigation liquid (for example, physiological saline, etc.) to flow out (eject) from the front end P1 side du...

Abstract

Provided is a catheter system that is capable of performing a suitable irrigation operation. The catheter system (5) comprises: an ablation catheter (1) having an irrigation mechanism; a power supply unit (32) that supplies electrical power to the ablation catheter (1) during ablation; a fluid supply unit (21) for supplying irrigation fluid to the ablation catheter (1); and a control unit (35). The control unit (35) controls so as to achieve high flowrate operation when the measured power (Pm) during ablation is in a high-power state at or above a threshold power (Pth), and controls so as to achieve low flowrate operation when the measured power (Pm) is in a low-power state below the threshold power (Pth). Furthermore, the control unit (35) quickly switches from low flowrate operation to high flowrate operation upon a transition from the low-power state to the high-power state and, upon a transition from the high-power state to the low-power state, if at the time of transition the low-power state has continued for a first standby time, the control unit (35) switches to low flowrate operation after maintaining high flowrate operation for the first standby time.

Description

technical field [0001] The present invention relates to a catheter system provided with a perfusion mechanism for, for example, treating arrhythmia and injecting a liquid such as physiological saline during ablation of an affected part of the treatment. Background technique [0002] Electrode catheters are inserted through blood vessels into the body (such as inside the heart) to detect and treat irregular heartbeats. In general, the shape of such an electrode catheter inserted into the body near the front end (distal end) changes (deflects, bends) in one direction or two directions according to the operation of the operation unit installed on the On the base (proximal, posterior, at hand) outside the body. In addition, in addition to the type in which the shape of the tip can be changed arbitrarily according to the operation, there is also a type in which the shape near the tip is fixed. [0003] However, among such electrode catheters, catheters used for treatment (so-ca...
