Abstract
Catheter blood pumps that include a collapsible blood conduit, a collapsible scaffold portion, and a bend formed in the collapsible scaffold. The collapsible blood conduit defines a blood lumen. The collapsible scaffold is adapted to provide radial support to the blood conduit. The blood pump also includes one or more impellers.
Claims21
A catheter blood pump comprising:
- a pump portion that includes:
- a collapsible blood conduit configured to be collapsible within a delivery device and expandable to an expanded configuration when deployed from the delivery device, the expanded configuration of the collapsible blood conduit including a blood conduit bend between a blood conduit proximal end and a blood conduit distal end,
- the collapsible blood conduit including a collapsible scaffold adapted to provide radial support to the collapsible blood conduit, the blood conduit bend including a scaffold bend between a scaffold proximal end and a scaffold distal end;
- and
- one or more collapsible impellers at least partially disposed within the collapsible scaffold.

A catheter blood pump comprising:
- a pump portion that includes
- a collapsible blood conduit configured to be collapsible within a delivery device and expandable to an expanded configuration when deployed from the delivery device, the blood conduit including a bend between a blood conduit proximal end and a blood conduit distal end such that a proximal portion of the collapsible blood conduit is not co-axial with a distal portion of the blood conduit,
- the collapsible blood conduit including a collapsible scaffold adapted to provide radial support to the collapsible blood conduit, the collapsible scaffold extending through the bend in the collapsible blood conduit;
- and
- one or more collapsible impellers at least partially disposed within the collapsible scaffold.

A method of making a pump portion of the catheter blood pump, the method comprising:
- forming a collapsible scaffold that has a configuration adapted to provide radial support to a blood conduit of the pump portion;
- deforming the scaffold from a first configuration to a bent configuration that includes a bend between a scaffold distal end and a scaffold proximal end;
- setting the collapsible scaffold in a bent configuration such that the bend is maintained in the scaffold.
