Abstract
Official abstract text for this publication.
Devices for moving blood within a patient, and methods of doing so. The devices can include a pump portion that includes an impeller and a housing around the impeller, as well as a fluid lumen. The impeller can be activated to cause rotation of the impeller and thereby move fluid within the fluid lumen.
First claim
Opening claim text (preview).
What is claimed is: 1. An intravascular blood pump, comprising: a collapsible housing including a fluid impermeable fluid conduit coupled to an expandable member, the expandable member having an open structure permitting flow therethrough, the fluid conduit including a distal end and a proximal end, a proximal portion of the expandable member extending proximally beyond the proximal end of the fluid conduit; and a collapsible impeller having an expanded configuration, a portion of the collapsible impeller being disposed outside of the fluid conduit while a remaining portion of the impeller is disposed in the fluid conduit. 2. The blood pump of claim 1 , wherein the collapsible impeller is disposed in a proximal portion of the collapsible housing, wherein the portion of the collapsible impeller disposed outside of the fluid conduit is proximal to the fluid conduit. 3. The blood pump of claim 1 , wherein from 20% to 50% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 4. The blood pump of claim 1 , wherein from 20% to 45% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 5. The blood pump of claim 1 , wherein from 20% to 40% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 6. The blood pump of claim 1 , wherein about 20% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 7. The blood pump of claim 1 , wherein about 25% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 8. The blood pump of claim 1 , wherein about 30% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 9. The blood pump of claim 1 , wherein about 35% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 10. The blood pump of claim 1 , wherein about 40% of the impeller, measured along an axial length of the impeller, is disposed outside of the fluid conduit. 11. The blood pump of claim 1 , wherein the impeller has a tapered proximal end region. 12. The blood pump of claim 11 , wherein the tapered proximal end region is disposed at least partially within a flared proximal end of the fluid conduit. 13. The blood pump of claim 1 , wherein the fluid conduit has a flared proximal end region. 14. The blood pump of claim 1 , wherein the fluid conduit has a flared distal end region. 15. The blood pump of claim 1 , wherein the impeller is disposed entirely within the expandable member. 16. The blood pump of claim 1 , wherein the expandable member has a distal portion extending distally beyond the distal end of the fluid conduit. 17. The blood pump of claim 15 , wherein the proximal portion of the expandable member tapers inward proximal to a proximal end of the impeller.
