Transcutaneous power transmission and communication for implanted heart assist and other devices

摘要

A system includes an implantable pump system for assisting blood flow in a patient including at least one movable valve. The movable valve is in a normally open state when the moveable valve is not being powered and a drive system in operative connection with the moveable valve to move the moveable valve under power. The system further includes an energy transfer system to provide energy to the drive system. The energy transfer system includes an external system including a power source and an external coil and an internal system including an internal coil adapted to receive transcutaneous energy transmitted from the external coil. The internal system has at least a first state wherein energy transmission from the external coil is required to provide operational power to the drive system.

1. A system, comprising:
an implantable pump system for assisting blood flow in a patient comprising: a drive system and an energy transfer system to provide energy to the drive system, the energy transfer system comprising:
an external system comprising a power source and an external coil, andan internal system comprising an internal coil adapted to receive transcutaneous energy transmitted from the external coil, the internal system having at least a first state wherein energy transmission from the external coil is required to provide operational power to the drive system, the implantable pump system having a normally open state such that blood can flow therethrough in the absence of application of energy to the drive system.
