Definitions

  • This application relates to blood pumps such as left or right ventricular assist devices with an expandable impeller for treatment of heart disease. Still more particularly, this application relates to expandable cannulas for use in such blood pumps, and to other structural features of these devices.
  • the pump includes a cannula having a compact state for insertion to the desired location and an expanded state; an impeller positioned within the cannula and having a hub and a plurality of blades supported by the hub, the hub including a passageway extending between a first end and a second end, each blade having a proximal end attached to the hub and a distal end, the impeller having a stored configuration and a deployed configuration; a valve positioned in the hub and having a first condition for occluding flow of a first fluid through the passageway from the first end to the second end, and having a second condition for occluding flow of a second fluid through the passageway from the second end to the first end; and a drive mechanism for rotating the impeller in the deployed configuration.
  • a pump for pumping fluid at a desired location includes a cannula having an inlet end, an outlet end, a compact state for insertion to the desired location and an expanded state.
  • the cannula includes a generally tubular reinforcing matrix having a plurality of circumferential rings each having an undulating pattern including a plurality of apexes pointing toward the inlet end and defining a plurality of recesses pointing toward the outlet end, and a plurality of apexes pointing toward the outlet end and defining a plurality of recesses pointing toward the inlet end.
  • FIG. 7A and 7B are longitudinal, highly schematic views of one embodiment of the blood pump of Fig. 1 in the deployed and stored configurations, respectively, showing system components;
  • FIG. 11 is a perspective view of a blood pump in a deployed configuration, showing one embodiment of an inlet guide vane assembly
  • FIGs. 8 A and 8B show an embodiment of blood pump 10 having an axially slidable storage housing 46.
  • bearing housing 84 can have a reduced diameter portion 90 between its ends housing bearings 80. This reduced diameter portion thus defines a longitudinal space for sliding movement of an internal rib 94 defined by an indented annular channel 96 in storage housing 46.
  • regions 59 can be applied using the same solvent casting technique described above in connection with the formation of polymer ring 145 adjacent inlet 52.
  • regions 59 can be formed separately and jointed to coating 50 in the desired locations.
  • Regions 59 can extend either fully or intermittently along the length of expandable portion 44 of cannula 40 from proximal end 47 to distal end 45, and can have a variable geometry (e.g., length, width, and/or thickness) and variable properties (e.g., elasticity) along the length of expandable portion 44 to control the cannula properties.
  • the outer surface of the cannula 40 can be advantageously configured such that clinically significant abrasion of the aortic valve does not occur upon expansion. After expansion of expandable portion 44 of cannula 40, the guide wire 72 can be removed.
