Silver motor stator for implantable blood pump
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.
1. An implantable blood pump comprising:
a solid wall tubular housing having a first open end and a second end defining a flow path therebetween and a longitudinal axis extending through the flow path;
a rotor positioned within the tubular housing; and
a motor including a first stator and a second stator each including a silver wire forming an outermost region of the blood pump, the first stator being positioned on a first side of the tubular housing and the second stator being positioned on a second side of the tubular housing opposite the first side of the housing relative to the longitudinal axis.
2. The blood pump of claim 1 , wherein the first stator and the second stator are approximately 180 degrees from each other relative to the longitudinal axis.
3. The blood pump of claim 1 , wherein the first stator and the second stator are equidistant from each other relative to the longitudinal axis.
4. The blood pump of claim 1 , wherein the silver wire is configured to contact a body fluid when the blood pump is implanted in a patient.
5. The blood pump of claim 1 , wherein the silver wire is a discrete filament including an insulation covering.
6. The blood pump of claim 1 , wherein the silver wire is a conductor pathway laminated onto a dielectric substrate.
7. An implantable blood pump comprising:
a solid wall tubular housing including an inner portion and an outer portion;
a rotor disposed within the inner portion of the housing; and
a motor including a plurality of stators positioned circumferentially from each other on the outer portion of the tubular housing, the plurality of stators each including a silver wire forming an outermost region of the blood pump.
8. The blood pump of claim 7 , wherein the silver wire is configured to contact a body fluid when the blood pump is implanted in a patient.
9. The blood pump of claim 7 , wherein the housing defines a flow path and a longitudinal axis extending through the flow path, and the silver wire forms a distalmost outermost region of the blood pump relative to the longitudinal axis.
10. The blood pump of claim 9 , wherein the plurality of stators are positioned 180 degrees from each other relative to the longitudinal axis.
11. The blood pump of claim 7 , wherein the housing includes a length terminating along a side portion of at least one of the plurality of stators.
12. The blood pump of claim 7 , wherein the silver wire is a conductor pathway laminated onto a dielectric substrate.
