1. Система загрузки имплантата, содержащая воронку для загрузки расширяющегося имплантата в направляющий катетер для подачи в желудочек для терапии сердечной недостаточности, отличающаяся тем, что она содержит:
воронку, имеющую расширяющийся на конус первый конец и второй конец, причем расширяющийся на конус первый конец предназначен для приема и сжатия расширяющегося имплантата; и
втулку, разъемно присоединенную ко второму концу воронки, причем втулка предназначена для переноса расширяющегося имплантата в направляющий катетер.
2. Система загрузки имплантата по п. 1, в которой воронка содержит первый участок на первом конце и второй участок на втором конце, причем первый участок содержит сужающуюся приемную часть для приема расширяющегося имплантата, а второй участок содержит просвет с первым диаметром.
3. Система загрузки имплантата по п. 2, в которой втулка содержит просвет со вторым диаметром, причем первый диаметр больше второго диаметра.
4. Система загрузки имплантата по п. 2, в которой втулка содержит соединительный элемент, расположенный на центральном участке втулки.
5. Система загрузки имплантата по п. 4, в которой втулка содержит трубчатый участок, расположенный дистально по отношению к соединительному элементу, причем трубчатый участок предназначен для введения во второй участок воронки.
6. Система загрузки имплантата по п. 5, в которой трубчатый участок втулки имеет длину, которая примерно равна длине просвета второго участка воронки.
