Invented by Peter Andrew Crosby, John Woodard, TC1 LLC
The TC1 LLC invention works as followsAn active implantable medical device that includes a therapeutic, controller, and at least one rechargeable batteries. A single hermetically sealed housing contains a rechargeable, therapeutic, and controller. Additionally, a hermetically sealed enclosure protects a wireless interface as well as a commutator.
Background for Implantable medical devices
An electrode system is an active implantable medical device that provides the therapeutic action. A pacemaker or implantable cardiac defibrillator can be built in such a manner that all components, except the ones providing therapeutic action, are contained within a single package. This is often hermetically sealed. There are more complex active implantable medical devices or those with a mechanical therapeutic effect (such as AbioCor). Implantable artificial hearts by Abiomed, Danvers (Mass., USA) have been in the past placed in multiple parts with separate hermetically sealed housings. The components typically included a controller, at most one battery, and a therapy device. A therapeutic device is a medical device that actively treats a patient’s medical condition and requires power to operate. Some examples of therapeutic devices are pacemakers, left ventricle assistance devices, cochlear implant, implanted hearing aids and neural simulators.
The implanted medical devices can be bulky because each component includes its own hermetic sealed housing. Patients who have been implanted with such devices may be at greater risk of infection due to the increased surface area of multiple hermetical sealed homes. Multiple components can increase manufacturing costs and compromise system reliability.
U.S. Pat. No. No. No. No. These disclosures only describe a therapeutic device that includes a battery. They do not include a device controller or controller within the hermetically sealed housing. The devices might require an additional implanted controller or controller that is carried externally relative the patient.
The present invention seeks to at least address or improve one or more of those disadvantages that are associated with the prior art.
BRIEF DESCRIPTION ABOUT THE INVENTION
According to a first aspect, the present invention comprises an implantable medical device that includes a therapeutic device and a controller. At least one rechargeable lithium battery is also included. A single hermetically sealed housing contains said therapeutic device, said controller, and said rechargeable batteries.
Preferably said hermetically sealed housing also encapsulates wireless interface.
Preferably said hermetically sealed housing also encapsulates the commutator.
Preferably said therapeutic device is a Rotary Blood Pump.
Preferably, a percutaneous leads is connected thereto.
Preferably, the TETS is connected to it.
According to a second aspect, the present invention comprises an active implantable medical system comprising a therapeutic instrument, a controller and an electrically conductive coil. At least one rechargeable batteries is also included. A first hermetically sealed housing contains said controller, said coil, and said rechargeable lithium battery.
Preferably, a second hermetically sealed enclosure encapsulates the therapeutic device.
According to a third aspect, the present invention comprises an active implantable medical system comprising a therapeutic device and a controller. An electrically conductive coil and at least one rechargeable batteries are enclosed in a first hermetically sealed enclosure.
According to a fourth aspect, the present inventions consist of a controller for therapeutic devices disposed within an implantable medical device. Said controller and therapeutic device are adapted to be powered at least by one rechargeable lithium battery. The housing containing said controller, said therapeutic device, and said rechargeable batteries is hermetically sealed.Click here to view the patent on Google Patents.
