Description
[1]本出願は、2011年11月28日に出願された米国仮特許出願61/563,935号の優先権を主張し、参照することによりその全体が本明細書に組み込まれる。
[2]本書は、一般に、超音波イメージングカテーテルに関する。本書は、より具体的には、撮影機能を集積したアブレーションカテーテルに関する。本書は、また撮影機能を集積した無線周波数(RF)アブレーションカテーテルに関する。
[3]無線周波数カテーテルアブレーションは、心不整脈を治療するために使用することができる。通常は、心筋細胞は洞結節と呼ばれる特殊な細胞の領域に由来する電気インパルスによって刺激される。洞結節からの電気インパルスは心臓の伝導繊維に沿って動き、均一で規則的に収縮する心筋を刺激し、心拍を生成する。
