| 摘要 |
The present invention relates to a tissue ablation device assembly which is adapted to form a conduction block along a length of tissue between two predetermined locations along the left atrial wall. The assembly comprises an ablation element on an elongated ablation member that is coupled to each of two delivery members, wherein the delivery members are adapted to controllably position and secure the ablation element along the length of tissue between the predetermined locations. A linear lesion in the tissue between the predetermined locations is then formed by actuation of the ablation element. The invention further provides that the ablation member may slideably engage one or two delivery members such that an adjustable length of the ablation element along the ablation member may be extended externally from the engaged delivery member and along a length of tissue. |
