POSITION INDEPENDENT CATHETER |
摘要 |
A catheter for treating tissue is disclosed, the catheter having slotted openings on a circumference of its distal portion, wherein each slotted opening spans at least about 25% of the circumference of the catheter. The disclosed catheter is capable of treating a variety of tissue in a variety of configurations. For example, in an ablation catheter of the disclosed invention, the slotted openings on the distal portion allow the ablation catheter to create effective lesions in both the pulmonary veins and the posterior wall of the left atrium. The ablation catheter preferably carries a conductive medium to help deliver ablation energy (e.g., RF) to the tissue being ablated. The configuration of the catheter permits ablation to be conducted in many varieties and geometric orientations independently of the tissue orientation. Also disclosed is a method of ablating tissue using catheter with slotted openings.
