Abstract

В заявке описаны устройство и способ добавления лекарственного средства или химического соединения (25) в жидкость, протекающую по трубке или катетеру (20). В одном из вариантов внутренняя поверхность такого катетера покрыта полимерной матрицей (55), в частности гидрогелем. Молекулы гидрогеля удерживают в матрице терапевтически активное вещество (65). Для удержания в матрице терапевтически активного вещества можно использовать различные методы, включая образование фотолабильных связей между терапевтически активным веществом (65) и гидрогелем (55). Терапевтически активное вещество (65) высвобождается из гидрогеля (55) при воздействии на него энергией, например лазерным излучением (35) определенной длины волны, которое входит в резонанс с фотолабильными связями и тем самым разрушает их. Высвобождающееся при этом терапевтически активное вещество (65) диффундирует из гидрогеля (55) в жидкость, протекающую через сквозное отверстие (60) катетера (20).Отчет о международном поиске был опубликован 2002.01.10.
