Abstract

다수의 외부 루우멘들(18)이 중심 루우멘 주위로 길이방향으로 연장하는 혈관 또는 관계통기관의 벽들에 의약을 공급하기 위한 슬리이브 캐데터에 있어서, 외부 루우멘들은 머리부분의 영역속에 반경방향 배출구멍들(24)을 가지며, 확장가능하게 되도록 풍선 캐데터의 풍선위에 즉, 팽창되어야 할 혈관의 배부벽과의 접촉속으로 적어도 부분적으로 배치되기 위하여 풍선 캐데터(11)위로 슬라이드가능하게 되어서, 직접적으로 외부 루우멘들 근방의 혈관의 조직에, 압력하에서 외부 루우멘들속의 배출구멍들(24)을 통하여 의약이 공급될 수 있다.
