Abstract
A system for cleaning an implanted blood pump, comprising: an inflow catheter having an expandable inflow member positioned about the periphery thereof; an inflow tube coupled with the inflow catheter; a valve assembly coupled to the inflow tube; an outflow tube coupled to the valve assembly; and an outflow catheter having an expandable outflow member positioned about the periphery thereof, the outflow catheter being coupled to the outflow tube. In use, the inflow tube and outflow tube extend through the skin of a human body, the inflow catheter and outflow catheter are positioned within the human body, and the valve assembly is positioned outside the human body.
Claims18
A system for cleaning an blood pump configured to be implanted in a human body, comprising:
- an inflow catheter having an expandable inflow member positioned about the periphery thereof, the expandable inflow member being expanded outwardly from the inflow catheter forming a seal between the inflow catheter and an inflow cannula of the blood pump;
- an inflow tube coupled with the inflow catheter;
- a valve assembly coupled to the inflow tube;
- an outflow tube coupled to the valve assembly;
- and
- an outflow catheter having an expandable outflow member positioned about the periphery thereof, the outflow catheter being coupled to the outflow tube, the expandable outflow member being expanded outwardly from the outflow catheter forming a seal between the outflow catheter and an outflow cannula of the blood pump.
A system for cleaning an blood pump, comprising:
- a blood pump configured to be implanted within a human body, the blood pump having an inflow cannula and an outflow cannula;
- an inflow catheter having an expandable inflow member positioned about the periphery thereof, the expandable inflow member being configured to be positioned within the inflow cannula of the blood pump and within the human body, the expandable inflow member being expanded outwardly from the inflow catheter forming a seal between the inflow catheter and the inflow cannula of the blood pump;
- an inflow tube coupled with the inflow catheter, the inflow tube being configured to extend through the skin of the human body;
- a valve assembly coupled to the inflow tube, the valve assembly being configured to be positioned outside of the human body, the valve assembly including—
- isolation valves at either end, and
- at least one input valve and at least one output valve to selectively allow a rinsing fluid to be circulated through the implantable blood pump;
- an outflow tube coupled to the valve assembly, the outflow tube being configured to extend through the skin of the human body;
- and
- an outflow catheter having an expandable outflow member positioned about the periphery thereof, the outflow catheter being coupled to the outflow tube, the expandable outflow member being configured to be positioned within the outflow cannula of the blood pump and within the human body, the expandable outflow member being expanded outwardly from the outflow catheter forming a seal between the outflow catheter and the outflow cannula of the blood pump.
