Description
尚、血栓捕捉部材が、イ.複数のワイヤが螺旋状に巻かれ、先端部と基端部が径方向内方に収束すると共に中間部が径方向外方に膨らんだ紡錘形状のワイヤ部材と、ロ.孔を有し、ワイヤ部材の先端部側の略半分の部分に外嵌固定されるフィルターを有することもある。
又、ガイドチップの先端側を構成する先端側構成部の先端部が基部よりも小径とされているので、血栓捕捉カテーテルを血管内を移動させて、その先端部を目的の血管狭窄部へ導く際に、血栓捕捉カテーテルが血液から受ける移動抵抗を小とできる。
更に、血栓捕捉部材が血栓捕捉部材デリバリー用シース内に格納された際に、ガイドチップの先端側構成部の基端面がシースの先端面と当接して、ガイドチップのシース内への過度の引き込みが阻止されるので、ガイドチップに挿通されたガイドワイヤーがシース内に挟み込まれる惧れはない。又、血栓捕捉部材を血栓捕捉部材デリバリー用シース内に格納し、血管内を移動させて、その先端部を目的の血管狭窄部へ導く際には、血栓捕捉部材がシース内に格納されているが、この格納時には、シースの先端開口がガイドチップの先端側構成部により閉塞されているので、上記移動時に、血液がシース内に全く乃至は殆ど侵入しない。
