Description
(発明の分野)
本発明は、体内の脈管または体腔の拡張器に関し、および脈管または体腔を拡張しそしてその中にシースを導入するための導入器アセンブリに関する。
第1の局面によると、本発明は、体内の脈管用の弾性的に可撓性である拡張器を含む。この拡張器は、脈管中への拡張器挿入を容易にするために一つの端部に向かってテーパ状になっており、そして上記一つの端部に近接する第1の端部および上記一つの端部の遠位方向にある第2の端部とを有する移行領域を有する。移行領域における拡張器の物理的特性は、移行領域の第2の端部における拡張器の可撓性が、移行領域の第1の端部における拡張器の可撓性よりも小さいというものである。
本発明による、弾性的に可撓性である脈管用の拡張器を、図1および図2において概して10で示す。拡張器10は、実質的に円筒形状のシャフト11と、端部12に隣接するテーパ状部分と、長手方向に延びる軸方向孔13とを備える。
拡張器20は大動脈40を通って、腎臓動脈43および44近傍まで押され、その後シース31を残して引き抜かれる。シース31は図6Cに示すように、大動脈40中を延びる。
当業者であれば、概略的に記載された本発明の思想および範囲から逸脱することなく、特定の実施形態に示される本発明に対して多くの変更および/または改変がなされ得ることを理解する。従って、現在の実施形態は、すべての点で例示であって制限的でないとして考慮されるべきである。
一つの端部(12)に向かってテーパ状になっており、そしてこの一つの端部(12)から離れて拡張器に沿って可撓性が減少する移行領域(14)を備えた弾性的に可撓性の体内脈管または体腔用拡張器(10)。拡張器(10)は、大動脈瘤を架橋する体腔内移植片の配置に用いるガイドワイヤ(32)上を摺動するように構成される拡張器を含む。拡張器はまた、弾性的に可撓性の材料(23)の外層により取り囲まれる、比較的剛直性の材料(21)の内部コアを備え得る。
