Summary:PROBLEM TO BE SOLVED: To provide a system and method for delivering energy to tissue.SOLUTION: Methods and apparatus for treating a patient include an ablation device for treating atrial fibrillation. The device includes a housing having proximal and distal ends, and an energy source adjacent to the distal end of the housing. The energy source has an active portion and an inactive portion. The active portion is adapted to deliver energy to tissue when the energy source is energized. This creates a partial or complete zone of ablation in the tissue that blocks abnormal electrical activity, thereby reducing or eliminating atrial fibrillation in the patient. The inactive portion does not emit energy or emits substantially no energy when the energy source is energized. 【課題】組織にエネルギーを送達するシステムおよび方法の提供。【解決手段】患者を治療する方法および装置は、心房細動を治療する切除デバイスを含む。デバイスは、近位端と、遠位端と、ハウジングの遠位端に隣接するエネルギー源とを有するハウジングを含む。エネルギー源は、活動部分と不活動部分とを有する。活動部分は、エネルギー源に電力が通されたとき、組織にエネルギーを送達するように適合される。これは、組織に部分的または完全な切除帯を作り、切除帯は異常な電気的活動をブロックし、それによって、患者の心房細動を減少させるかまたは除去する。不活動部分は、エネルギー源に電力が通されたとき、エネルギーを放出しないかまたは実質的にエネルギーを放出しない。【選択図】図1
