Abstract
Catheter blood pumps that include an expandable pump portion. The pump portions include an collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pump portion also includes one or more impellers.
Claims10
An intravascular blood pump, comprising:
- a pump portion that includes
- a collapsible blood conduit;
- a plurality of distal struts extending distally from the collapsible blood conduit, wherein distal ends of the distal struts are secured to a distal end portion of the pump portion that is disposed about a long axis of the pump portion, the collapsible blood conduit having an expanded configuration with a radially outermost dimension greater than a radially outermost dimension of the distal end portion;
- a pressure sensor secured to the distal end portion, the pressure sensor having a pressure sensitive region positioned such that it is exposed to a flow of blood moving toward an inflow of the pump portion;
- a pressure sensor connector comprising a wire, the pressure sensor connector being coupled to the pressure sensor and in communication with the pressure sensor, wherein the pressure sensor connector extends proximally from the pressure sensor and is coupled to a radially outer surface of a first strut of the plurality of distal struts;
- and
- one or more collapsible impellers at least partially disposed within the collapsible blood conduit.
