Description
この出願は、2002年8月2日出願の米国特許出願第10/211、418号(発明の名称「治療用超音波システム」)及び2002年9月20日出願の米国特許出願第09/251,227号(発明の名称「超音波カテーテルを変換器へ取り付けるコネクタ」)の一部継続出願である。これらの米国出願の全開示はここに完全に詳しく説明されるが、参照のためにここに組み入れられる。
第1吸収体98は遠位穴88内に座し、超音波伝達部材42受ける(すなわち、回りを囲む)穴を有する。吸収体100は近位穴84に座し、超音波伝達部材42受ける(すなわち、回りを囲む)穴を有する。言い換えれば、各吸収体98と100は超音波伝達部材42と、それぞれの穴88と84の間に置かれる。弾性材料で吸収体98,100を作ることができ、吸収体の非制限例はポリマ又はゴムを含む。代替的に、吸収体98,100をOリングの態様とすることができる。吸収体98,100は、横向きの微小運動を吸収して望ましくない横振動を最小にするように機能する。
