Problems solved by technology

At present, most of the means of checking the blocking effect are through X-ray fluoroscopy, which causes patients and doctors to receive more radiation dose during the operation, which is not conducive to health

Embodiment 1

[0075] Please refer to figure 1 and figure 2 , figure 1 It is a schematic diagram of the structure of the catheter that can be judged to be in the initial state provided by Embodiment 1 of the present invention, figure 2 It is a schematic diagram of the structure provided by Embodiment 1 of the present invention that can determine that the catheter that the balloon is attached to is in an occluded state. This embodiment provides a catheter capable of judging the adhering of the balloon, which is used for cryoablation at the target position 10, including:

[0076] The balloon structure includes an outer balloon 20 and an inner balloon 30 located inside the outer balloon 20, and there is a gap between the outer balloon 20 and the inner balloon 30 to form a balloon barrier, the The balloon barrier consists of at least one monitoring zone 40, said outer balloon 20 being made of a compliant material and said inner balloon 30 being made of a non-compliant material;

[0077] a ...

Embodiment 2

[0096] The difference from Example 1 is that please combine image 3 and Figure 4 , in this embodiment, the balloon compartment includes a plurality of independent monitoring areas 40, the second delivery channel includes several sub-channels 61, and the sub-channels 61 correspond to the monitoring areas 40 one-to-one. Gas is delivered to each of the monitoring areas 40 , and each of the monitoring areas 40 is provided with the detection module.

[0097] That is to say, each monitoring area 40 is independent of each other, and the gases in each monitoring area do not communicate with each other. Detecting the parameters representing the changes of the monitoring areas 40 by the detection module respectively can reflect whether the blocking of each monitoring area 40 is completed, so that relevant personnel can more accurately judge the blocking situation of each monitoring area 40, Improve the accuracy of blocking judgment.

[0098] Further, a plurality of partitions 70 ar...

Abstract

The present invention provides a catheter and an ablation system capable of judging the abutment of a balloon. The catheter includes: a balloon structure, including an outer balloon and an inner balloon located in the outer balloon, and a gap between the outer balloon and the inner balloon gap and form a balloon barrier, the balloon barrier consists of at least one monitoring area, the outer balloon is made of compliant material, the inner balloon is made of non-compliant material; the catheter shaft, including The first delivery channel for delivering coolant and the second delivery channel for delivering gas to the monitoring area; the detection module is used to detect the parameters that characterize the changes in the monitoring area, and the comparison between the parameters and the predetermined value can reflect the Whether the balloon structure reaches the predetermined position. By detecting the changes of relevant parameters in the monitoring area to judge whether the balloon structure has reached the predetermined position, and then judge whether the balloon structure is closely attached to the target position, it is possible to avoid health risks caused by using X-ray fluoroscopy to detect pulmonary vein occlusion. question.

Description

technical field [0001] The invention relates to the technical field of cryoablation, in particular to a catheter and an ablation system capable of judging the adhering of a balloon. Background technique [0002] Atrial fibrillation (Atrial fibrillation, referred to as atrial fibrillation) is one of the most common clinical arrhythmias, and its incidence increases with age. Compared with non-atrial fibrillation patients of the same age, the quality of life of atrial fibrillation patients is often poor. And it is often accompanied by diseases such as hypertension and heart failure, so its thromboembolic complications and fatality are relatively high. In order to solve this problem, an ablation method—Cryoballoon ablation (Cryoballoon ablation) began to be applied clinically. Cryoballoon ablation surgery for the treatment of atrial fibrillation has undergone multiple clinical trials and studies, confirming that it has the same safety and effectiveness as radiofrequency ablatio...
