関連出願の参照
本願は、2017年11月14日に出願され、「集束型腔内結石摘出カテーテル装置および方法」と題された米国仮出願第62/585719号の利益を主張し、当該出願の全体が参照により本明細書に組み込まれる。

発明の背景
発明の分野
本発明は、管腔内の結石破砕を行うために使用される装置に関し、より具体的には、血管内の狭窄物を破砕するための結石破砕カテーテルに関する。
末梢動脈疾患(PAD)は、心臓および脳の外側に位置する血管の疾患を指す。最も多くの場合、この疾患は、動脈に沈着する脂肪物または石灰化プラークによって引き起こされる。PADは、血管を狭くし、硬化させ、可撓性を低くするように血管に影響を与え、したがって、腕、腎臓、胃、最も一般的には下肢への血流を制限する。
PADの外科処置は、バイパス移植、バルーン血管形成/ステント挿入、および粥腫切除を含む。
図面を参照して、人体の解剖構造内の管腔または他の身体空間内に使用される電気機械的発生器およびカテーテルの様々な実施形態が示されている。本発明およびその方法は、好ましくは、血管、例えば動脈内の狭窄物または閉塞物を除去するために使用される。
