Abstract
A cardiac assistance system is provided that comprises two pumps and cannulae connected thereto. A first pump of the two pumps is configured to connect to a right heart system via a first fluid channel. The first fluid channel formed at least partially by a first two cannulae of the cannulae. A second pump of the two pumps is configured to connect to a left heart system via a second fluid channel. The second fluid channel formed at least partially by a second two of the cannulae. The two pumps are configured as rotary pumps for arrangement outside a patient's body.
Claims19
A cardiac assistance system comprising:
- two pumps and cannulae connected thereto, wherein a first pump of the two pumps is configured to connect to a right heart system via a first fluid channel, the first fluid channel formed at least partially by a first two cannulae of the cannulae, and wherein a second pump of the two pumps is configured to connect to a left heart system via a second fluid channel, the second fluid channel formed at least partially by a second two of the cannulae, wherein at least one of the cannulae includes a region configured to pass through skin, and wherein the two pumps are configured as rotary pumps, and the two pumps are further configured to operate outside a patient's body.
A method for operating a cardiac assistance system comprising:
- arranging a first pump and a second pump outside a patient's body;
- controlling operation of the first pump connected to a right heart system of the patient's body via a first fluid channel formed at least partially by a first two of a plurality of cannulae, wherein at least one of the cannulae includes a region configured to pass through skin;
- controlling operation of the second pump connected to a left heart system of the patient's body via a second fluid channel formed at least partially by a second two of the cannulae;
- and
- coordinating, based on controlled operation of the first pump or the second pump, at least one of respective pressures or respective volume flow in the first fluid channel and the second fluid channel.
A cardiac assistance system comprising:
- at least one extra-corporeal pump and a plurality of cannulae connected thereto, wherein the at least one extra-corporeal pump is configured to connect to a right heart system via a first fluid channel formed at least partially by at least a first one of the cannulae or to a left heart system via a second fluid channel formed at least partially by at least a second one of the cannulae, wherein the at least one extra-corporeal pump is formed as a rotary pump configured to operate outside a patient's body, and wherein one or more of the cannulae includes a region configured to pass through skin.
