Abstract
An implantable subcutaneous electrical socket and corresponding percutaneous plug are disclosed for controlling and/or energizing an implanted medical device, such as a bone distraction motor, within a patient. The subcutaneous electrical socket is accessed percutaneously by the plug, to connect data and power electrodes deployed from the plug into the socket to conduct control signals and electrical power from an external source to an implanted medical device within the patient. The socket and plug include insulating materials to prevent electrical shock to the patient.
Claims38
A medical device for establishing percutaneous delivery of electrical current, comprising:
- an electrical plug having a skin contact surface and at least two hollow needles, the hollow needles capable of extending from the skin contact surface;
- at least two power electrodes, each power electrode located inside one of the hollow needles, said power electrodes connected to an electric power source and movable between a non-deployed position where contacting ends of the electrodes do not protrude from the hollow needles and a deployed position where the contacting ends of the electrodes protrude from the hollow needles;
- and
- an implantable subcutaneous electrical socket having a plurality of receiving ports configured to receive the hollow needles, each receiving port electrically insulated from each of the plurality of receiving ports and having one or more lateral walls and a base defining a receptor space, where the base has a conductive base material.
30-55. (canceled)
An electrical plug for establishing percutaneous delivery of electrical current to a medical device implanted in a subject, comprising:
- a skin contact surface for contacting or coming within proximity to the skin of the subject;
- at least two hollow needles capable of extending from the skin contact surface and at least two power electrodes, each power electrode located inside one of the hollow needles, wherein the power electrodes are formed from a conductive material and connected to an electric power source, each of the power electrodes movable between a non-deployed position, where the power electrodes do not protrude from the hollow needles, and a deployed position, where the power electrodes protrude from the hollow needles;
- and
- an insulating material that insulates the power electrodes from coming into electrical contact with the hollow needles.
