Abstract
An implantable blood pump including a housing having an inlet cannula, a rotor disposed within the housing, the rotor in fluid communication with the inlet cannula, a stator disposed within the housing, the stator configured to rotate the rotor when a current is applied to the stator, and at least one ultraviolet light emitter disposed within the housing.
Claims17
An implantable blood pump, comprising:
- a housing including an inlet cannula;
- a rotor disposed within the housing, the rotor being in fluid communication with the inlet cannula;
- a stator disposed within the housing, the stator being configured to rotate the rotor when a current is applied to the stator;
- one from the group consisting of a ceramic disk and a tube disposed between the stator and the rotor;
- and
- at least one ultraviolet light emitter disposed within the housing and coupled to the one from the group consisting of the ceramic disk and the tube.

An implantable blood pump, comprising:
- a housing including a first portion, a second portion upstream from the first portion, and an inflow cannula extending from the first portion to the second portion along an axis;
- a rotor disposed within the housing for rotation about the axis;
- a first stator disposed within the housing downstream from the rotor;
- a first ceramic disk disposed within the housing between the first stator and the rotor;
- a second stator disposed within the housing upstream from the rotor;
- a second ceramic disk disposed between the second stator and the rotor;
- and
- an ultraviolet light emitter coupled to at least one of the group consisting of the first ceramic disk and the second ceramic disk, the ultraviolet light emitter being a flexible material.
