Claims (10)
1. Насосная система (10), содержащая насос (32), канал (50) входного потока, жидкостно-связанный с насосом (32) для направления крови в насос, и канал (52) выходного потока, жидкостно связанный с насосом (32) для направления крови из насоса, отличающаяся внесердечной конфигурацией и расположением, причем упомянутый насос (32) сконфигурирован для прокачивания крови со средней волюметрической скоростью приблизительно 3,0 л в мин и менее в течение продолжительного времени для направления крови между первым и вторым неглавными кровеносными сосудами для дополнения кровообращения у пациента, причем упомянутый канал (50) входного потока сконфигурирован для соединения с первым кровеносным сосудом подкожно и имеет внутренний диаметр не более приблизительно 25 мл, и при этом упомянутый канал (52) выходного потока сконфигурирован для соединения со вторым кровеносным сосудом подкожно и имеет внутренний диаметр не более приблизительно 25 мл, при условии, что в системе отсутствует оксигенатор.
2. Система по п. 1, в которой насос (32) сконфигурирован для прокачивания с волюметрической скоростью приблизительно 1,5 л в мин и ниже в течение продолжительного времени.
3. Система по п. 1, в которой насос (32) сконфигурирован для прокачивания крови пульсирующим образом, и в которой система далее содержит управление (42), сконфигурированное для синхронной работы насоса (32) во время равнообъемного сжатия и прекращения работы приблизительно тогда, когда аортальный клапан закрывается.
4. Система по п. 1, в которой насос (32) сконфигурирован для прокачивания крови пульсирующим образом, и в которой система далее содержит управление (42), сконфигурированное для работы насоса (32) обычно синхронно во время диастолы.
5. Система по п. 1, в которой насос (32), канал (50) входного потока и канал (52) выходного потока имеют такую конфигурацию, чтобы имплантироваться в пациента с помощью минимально инвазионной процедуры.
6. Система по п. 5, далее содержащая имплантируемый аккумулятор.
7. Система по п. 6, далее содержащая индукционную катушку, сконфигурированную для электромагнитного соединения с аккумулятором для зарядки аккумулятора после имплантации упомянутых аккумулятора и насоса.
8. Система по п. 1, далее содержащая соединитель (70), сконфигурированный для жидкостного соединения либо канала (50) входного потока, либо канала (52) выходного потока с сосудистой системой пациента.
