AI Technical Summary

Technical Problem

Existing ablation catheters cannot flexibly adjust the size of the ablation components according to the anatomical structure of the specific ablation target tissue, making it difficult to get close to the target tissue area, requiring multiple positioning and ablation, making the operation complex and time-consuming.

Method used

An ablation device was designed, including a support frame and an adjustment component. The radial dimension of the support frame is adjusted by the axial movement of the inner and outer sheaths, and a mapping device is provided to detect the electrophysiological signals of the target tissue area, so as to achieve precise proximity of the ablation component.

Benefits of technology

It simplifies the surgical procedure, reduces the difficulty of the surgery, and improves the accuracy and efficiency of ablation.

Abstract

The application provides an ablation device, which comprises an ablation assembly and an adjusting assembly arranged at the proximal end of the ablation assembly, wherein the ablation assembly comprises a supporting framework and an ablation element arranged on the supporting framework; the adjusting assembly comprises an inner sheath, an outer sheath and a diameter adjusting module; the outer sheath and the inner sheath are movably sleeved in the axial direction; the distal end of the outer sheath is connected to the proximal end of the supporting framework; the distal end of the inner sheath is connected to the distal end of the supporting framework; the inner sheath is connected to the diameter adjusting module; the diameter adjusting module moves in the axial direction to drive the inner sheath to move in the axial direction relative to the outer sheath, so that the supporting framework is deformed to change the radial size thereof. The ablation device provided by the application can adjust the radial size of the ablation assembly. The application further provides an ablation system.
