Abstract
Circulatory assist devices and methods are disclosed herein. In some variations, a circulatory assist system may be configured for placement in a cardiovascular lumen (e.g., aorta) and include a pump arrangement comprising a pump region configured to receive blood, an outflow region, and a pump in the pump region and configured to drive the received blood toward the outflow region. The circulatory assist system may further include a vascular seal configured to form a peripheral seal between the pump arrangement and an inner wall of the cardiovascular lumen.
Claims107
A blood pump system configured for placement in a vascular lumen, the blood pump system comprising:
- a pump arrangement comprising an outflow region and configured to receive blood and drive the received blood toward the outflow region;
- and
- a vascular seal configured to form a peripheral seal between the pump arrangement and an inner wall of the vascular lumen upstream of the outflow region.
A method comprising:
- positioning a pump device in a vascular lumen of a patient, the pump device comprising:
- a pump arrangement with an outflow region;
- and
- a vascular seal arranged adjacent the pump arrangement;
- forming a peripheral seal between the pump arrangement and an inner wall of the vascular lumen with the vascular seal;
- and
- operating the pump arrangement to receive blood and drive the received blood through the outflow region and into the vascular lumen downstream of the peripheral seal.
A blood pump system configured for placement in a vascular lumen, the blood pump system comprising:
- a pump arrangement comprising:
- a conduit with a pump region configured to receive blood and an outflow region;
- and
- a pump in the conduit and configured to drive the received blood through the outflow region,
- wherein at least a portion of the pump arrangement is configured to form a peripheral seal with an inner wall of the vascular lumen.
A method comprising:
- positioning a pump device in a vascular lumen of a patient, the pump device comprising a pump arrangement with a conduit having a pump region configured to receive blood and an outflow region, and a pump in the conduit;
- operating the pump to drive received blood toward the outflow region;
- and
- engaging an inner wall of the vascular lumen with a sealing portion of the pump device to form a peripheral seal around the pump device.
