発明の分野。本発明は、組織内でアンカーを配置および固定するための装置および方法に関する。より詳細には、本発明は身体内の組織の折り畳み部内でアンカーを配置および固定するための装置および方法に関する。
患者の身体内腔内に形成され得る襞の固定において、様々な方法および装置が実施され得る。一般的に、任意の数の従来方法が最初に襞を形成するために利用され得る。特に一つの方法は襞の形成を含み得、それを通して組織アンカーが内部または外部に配置され得る。組織襞形成装置の先端部は組織を係合または把持し得、係合された組織を装置の先端に対して近位に動かし得、それにより所定の大きさの実質的に均一な襞が提供される。係合または固定装置を送達するのに特に適した道具および方法の例は、2003年12月12日に出願され同時係属中の米国特許出願第10/735,030号に詳細に見られ、その全体が本明細書中に参考として援用される。
患者の体腔内に襞を最初に形成するために、種々の方法および装置が使用され得る。アンカー止めおよび固定装置は内視鏡器具を介して送達されて配置され得、この内視鏡器具は、胃腸管の組織壁に係合し、一またはそれ以上の襞を形成し、組織襞を通して一またはそれ以上のアンカーを配置する。組織アンカーは、胃腸管の筋層および/または漿膜層を通して配置され得る。
