Abstract
In one embodiment of the present invention, an implantable blood pump includes a housing defining a flow path, a rotor positioned within the flow path, and a motor including a stator, positioned outside of said housing, the stator including a length of silver wire, wherein the silver wire is not positioned within a hermetically sealed compartment once the blood pump is ready for implantation into a patient in need thereof. The present invention may also include a method of implanting the implantable blood pump including the step of implanting the blood pump within the patient and within or adjacent to the vasculature.
Claims13
An implantable blood pump comprising:
- a housing defining a blood flow path and a longitudinal axis extending along the blood flow path;
- a rotor positioned within the blood flow path;
- and
- a motor including at least two stators positioned outside of the housing and each including a portion overlapping an adjacent stator and a silver wire forming a distalmost outer region of a portion of a blood pump relative to the longitudinal axis, the silver wire being configured to directly contact a body fluid when implanted within a patient.
A method of implanting an implantable blood pump, the method comprising:
- providing an implantable blood pump including:
- a housing defining a blood flow path and a longitudinal axis extending along the blood flow path;
- a rotor positioned within the blood flow path;
- and
- a motor including at least two stators positioned outside of the housing and each including a portion overlapping an adjacent stator and a silver wire forming a distalmost outer region of a portion of a blood pump relative to the longitudinal axis;
- and
- implanting the implantable blood pump into one of a heart and through a wall of the heart of a patient.
An implantable blood pump, comprising:
- a blood pump housing defining a blood flow path and a longitudinal axis extending along the blood flow path;
- a rotor mounted for rotation within the blood pump housing;
- and
- a motor including at least two stators mounted on an outside of the blood pump housing, the at least two stators each including a portion overlapping an adjacent stator and a silver wire coil forming a distalmost outer region of a portion of a blood pump relative to the longitudinal axis.
