Document Type and Number:
WIPO Patent Application WO/2017/206266
Kind Code:
A1
Abstract:
A basket-type ablation catheter and an ablation device. The basket-type ablation catheter comprises an electrode portion. The electrode portion has a basket shape, and comprises a guidewire (1) and a plurality of electrode sets distributed along the circumference of the guidewire, wherein the electrode set comprises at least two electrode bands (2). The electrode band (2) comprises a radio frequency emitting electrode band and a radio frequency receiving electrode band. The ablation device comprises a radio frequency source and the basket-type ablation catheter. The basket-type ablation catheter and ablation device can implement deep or shallow ablation, achieve good ablation performance, and can ablate different pathogenic parts or pathogenic tissues of different shapes. The invention is highly adaptable, and integrates the functions of ablation, marking, excitation, and resistance measurement within a single device, therefore eliminating a need to use additional marking and measurement catheters for performing marking and measurements, greatly reducing pain experienced by a patient while lowering treatment costs. The invention is safe and offers a high level of reliability.
