Title:
複数の長手方向の電極セグメントを有する展開する電極デバイス
Document Type and Number:
Japanese Patent JP6647374
Kind Code:
B2
Abstract:
Methods, systems, and devices for providing treatment to a tissue in body lumens are described. The system may include a catheter, an expansion member coupled with a distal portion of the catheter, an ablation structure including one or more longitudinal electrode segments, and an ablation structure support coupled to the ablation structure configured to at least partially unfurl as the expansion member expands and furl as the expansion member contracts. The ablation structure may include multiple separately wired and/or separately controlled longitudinal electrodes, longitudinal electrode zones, or both, such that each longitudinal electrode or longitudinal electrode zone may be selectively enabled or selectively disabled. In some instances, one or more springs are coupled to the ablation structure configured to promote unfurl or furl around the expansion member. In some instances, one or more protection elements are positioned along the catheter.
