An ablation catheter

Abstract

The utility model relates to medical instrument technical field provides an ablation catheter, include: outer tube, inner tube subassembly, the proximal end of inner tube subassembly can be along the axial direction movement of outer tube is inserted in the outer tube, basket electrode subassembly includes a plurality of electrode arms, a plurality of electrode arms send out from the inner tube subassembly far end and gather in outer tube far end, the far end of inner tube subassembly has plane structure to make after the far end connection of inner tube subassembly and basket electrode subassembly in the plane end head of far end formation of ablation catheter. The utility model provides an ablation catheter, the far end of inner tube subassembly has plane structure to make after the far end connection of inner tube subassembly and basket electrode subassembly in the plane end head of far end formation of ablation catheter, compared with the ablation catheter in the prior art, because the far end of ablation catheter is plane end head, in the treatment process, when ablation catheter enters the heart cavity, can reduce the risk that ablation catheter head end punctures the inner wall of heart cavity.
