Mobility-enhancing blood pump system
First Claim
1. A partially implantable blood pump system comprising:
- an implantable blood pump;
an implantable internal controller coupled to the implantable blood pump;
an implantable rechargeable battery coupled with the internal controller; and
a percutaneous cable coupled with the implantable internal controller and extending through a skin of a patient, the percutaneous cable being configured to releasably couple the internal controller with an external power source and/or an external controller and to provide both power and data transfer to the implantable internal controller, the percutaneous cable comprising a plurality of lead sets, each of the lead sets configured to alternately provide power and data to the implantable internal controller such that power provided from one or more of the lead sets is temporarily discontinued while data is provided from one or more of the lead sets to the implantable internal controller;
wherein the internal controller is configured to;
determine a power level of the rechargeable battery;
adjust recharging of the rechargeable battery with the external power source based on the determined power level of the rechargeable battery;
receive pump information associated with an operational speed of the implantable blood pump from the implantable blood pump, the pump information associated with the operational speed of the implantable blood pump comprising at least one of an inlet or outlet pressure of the implantable blood pump and a blood flow through the implantable blood pump;
transmit the pump information associated with the operational speed of the implantable blood pump to the external controller;
receive commands from the external controller to change the operational speed of the implantable blood pump; and
adjust power delivery to the implantable blood pump from the external power source or the rechargeable battery to control the operational speed of the implantable blood pump.

Abstract
A blood pump system includes a first implantable housing, an implantable blood pump independent from the first implantable housing, and a percutaneous extension. The first implantable housing includes a rechargeable power storage device. The implantable blood pump supplements the pumping function of a heart. The rechargeable power storage device supplies electrical power to the implantable blood pump. The percutaneous extension is coupled to the rechargeable power storage device and adapted to traverse the skin. The percutaneous extension is configured to releasably connect to an external power supply adapted to provide power for recharging or supplementing the rechargeable power storage device to power the implantable blood pump.
