Invented by Steven T. Deininger, Michael J. Baade, Charles E. Peters, Medtronic Inc
The Medtronic Inc invention works as follows
An implantable device includes a enclosure sleeve made of grade 5 titanium. The enclosure sleeve includes a circuitboard that has at least a portion circuitry for a pulse-generating device and a battery electrically connected to that portion circuitry. The enclosure sleeve is fitted with a bottom cap. The enclosure sleeve is attached to a connector block module assembly. The connector block module assembly has a plurality of leads connections within it. Feedthrough pins transmit stimulation signals from the pulse generator to lead connections in the connector block module. “A ground conductor is located within the enclosure sleeve, electrically connected to the circuit board. A ground pin is also electrically attached to the ground conductor.Background for Implantable medical device
Implantable Medical Devices (IMDs), typically, include a connector assembly mounted on a sealed enclosure. The connector enclosure assembly receives the proximal end a medical led and provides electrical connectivity to the electrical circuitry within the enclosure of the device and the conductors in the medical lead. The connector enclosure assembly can be used to secure the medical lead while isolating the electrical connections against external conditions, such as body fluids.
It is desirable that medical devices become smaller and less intrusive. It is especially true for implantable devices, where a smaller device allows a smaller pocket to form in the patient. A smaller size can present design challenges. This is especially true for the connector enclosure assembly where there may be a certain number of electrical contact. The medical lead is usually implanted in such a way that it is in excess near the medical device. It is also difficult to orient the excess lead when it leaves the device.
Embodiments” address these issues and others by providing medical device connector assembly enclosures that include a lead path that is angled in relation to the plane of a base. The angled lead can be combined with other design features in order to achieve a small connector enclosure assembly.
Embodiments” provide a connector enclosure assembly for a medical device that includes a housing with an opening, a base defining plane, and an electrical connector within the housing. The electrical connector aligns with the opening, forming a lead-passageway. This lead passageway is at an angle of greater than zero degrees but less than 90 relative to the plane. “A feedthrough pin extends from the housing to contact the electrical connector.
Embodiments” provide a connector enclosure assembly for a medical device that has a housing with an opening, and a base that defines a plane. The housing contains a plurality of electrical plugs, separated by an interfering seal that contacts electrical connectors from each side. The electrical connectors align with the opening and form a lead path. The lead passageway is angled at an angle greater than zero but less than 90 degrees with respect to the plane.
