Definitions

  • This invention relates to a connector system for use for implanted prosthesis and/or sensor arrangements, including but not limited to cochlear implants and implantable hearing prosthesis systems.
  • a primary requirement is to minimise trauma to the patient, both from the surgical procedure and ongoing during everyday activities.
  • the present invention provides a percutaneous connector set, comprising: a base unit adapted to be affixed to an underlying body structure, including a plurality of separate electrical conduction paths extending from a set of contact points on a surface operatively projecting beyond a body, to a set of wires extending within said body; a feed through unit removably connectable to the base unit, including a set of conduction paths corresponding on one end to the contact points on the base and on the other end to a first part of a detachable connector set; and an external connector unit including a second part of a detachable connector set.
  • the present invention comprises a replaceable connector set operatively adapted to be connected to a base unit affixed to an underlying body structure, said base unit including a plurality of separate electrical conduction paths extending from a set of contact points on a surface projecting beyond a body, to a set of wires extending within said body, wherein said connector set comprises a feed through unit operatively connectable to the base unit, including a set of conduction paths corresponding on one end to the contact points on said base unit and on the other end to a first part of a detachable connector set, and an external connector unit including a second part of a detachable connector set.
  • One embodiment of the present invention employs a small, biocompatible pedestal, fixed to the skull and passing through the skin with external, replaceable components attached by means of a screw fixed in the pedestal.
  • the diameter of the base section passing through the skin preferably is of minimal dimension in order to reduce the possibility of passing fluids or bacteria to and from the body.
  • the overall profile of the pedestal is minimised for aesthetic reasons in addition to reducing the disturbance to a patient's everyday activities.
  • Fig. 1 shows in perspective, partly in section, one embodiment of a percutaneous connector system according to the present invention.
  • FIG. 1 a preferred embodiment of a percutaneous connector system is illustrated.
  • the system may be conveniently described by reference to a number of sub-assemblies whose descriptions are provided below.
  • a threaded fastener which is, for example, a titanium component threaded internally and slotted on the top in order to provide a convenient means of connecting replaceable components to the base unit 5.
  • the feedthrough screw 2 is, for instance, made of titanium, and is preferably hermetically sealed within the conductor unit 6 to provide a threaded section for the attachment of the removable connector 9 and the uni-directional conductive washer 7 by means of the threaded fastener 1.
  • Pins 3, are hermetically sealed within the conductor unit 6 and these provide a means of passing signals to and/or from the internal lead 11.
  • a biocompatible fixation material 4 for example Dow Corning MDX-4-
  • 4210 Medical Grade Silastic is preferably filled around the connections to the pins 3 to protect the delicate connections from external forces and disturbances.
  • pins 3 be formed from a suitable biocompatible conductive material, such as platinum/iridium alloy.
  • Conductor unit 6 is preferably formed from a ceramic material.
  • the base unit 5 is a critical component of the system and is preferably made of titanium.
  • the lower flanged base is, in a cochlear implant application, preferably attached to the skull by means of four titanium screws 10. It will be appreciated that alternative fixation points and methods of fixation will be appropriate depending upon the devices to which the percutaneous connector is affixed.
  • the neck of the lower flange 12 preferably reduces to a minimal diameter to pass through the skin. This allows for the area around which skin does not regrow to be minimised. On the external side, the diameter is increased to aid in providing a smooth, rounded surface for the skin and tissue to grow around in order to provide a barrier to fluids and bacteria passing to and from the body.
  • Flange 13 provides a mechanical barrier so as to minimise the risk of trauma in use to the regrown area of skin.
  • the upper section hermetically seals the conductor unit 6 and is for example laser welded around the outer edge to the base unit 5.
  • a conductor unit 6 is employed.
  • the conductor unit 6 illustrated contains 64 pins 3 embedded within it.
  • the conductor unit 6 is sealed by, for example, brazing to the base unit 5.
  • a platinum tube housing a screw 2 passes through the conductor unit 6. This method provides a hermetical seal across the base of conductor unit 6.
  • the surface of the conductor unit 6 is preferably polished to a mirror finish to maintain a reliable connection to the uni-directional conductive washer 7.
  • a uni-directional conductive washer 7 is preferably used for connection, and is preferably formed from a commercially available material which provides a convenient and reliable method of connecting the pins 3 of the conductor unit 6 to the pins of the feedthrough 9.
  • the material contains a high density of vertically positioned conductive fibres embedded within an insulating material. This allows for signals to pass perpendicularly to the surface of the material while substantially insulating parallel to the surface.
  • the feedthrough 9 illustrated contains 64 individual connector sockets 8 for the purpose of connecting to an external plug 15 and transmitting signals to the lower face of the feedthrough 9 for transmission through the uni-directional conductive washer 7 to pins 3.
  • 64 individual connector sockets 8 for the purpose of connecting to an external plug 15 and transmitting signals to the lower face of the feedthrough 9 for transmission through the uni-directional conductive washer 7 to pins 3.
  • signals may be required for signals to pass in both directions, or the opposite direction, and this is readily implemented with the arrangement shown.
  • Feedthrough unit 9 contains 64 sockets 8 in an identical pattern to the pins 3 embedded within the conductor unit 6.
  • the connector on the upper side 16 attaches to its opposite gender plug 14 (coming from for example the stimulation source or a monitoring device) and passes the signal through the feedthrough 9 to the lower side where the interface with the uni-directional conductive washer 7 provides a reliable connection to the conductor unit 6 and its pins 3.

Abstract

Ce système de raccordement transcutané permet à un appareil externe de communiquer des signaux électriques à un appareil implanté dans le corps, par exemple une prothèse cochléaire. Dans une réalisation préférée, le système de raccordement comprend une embase (5) fixée sur un os ou une structure interne du corps, une unité de traversée (9) connectée à l'embase (5) mais pouvant s'en désolidariser, et un élément externe (15) amovible. L'unité de traversée (9) et l'élément amovible (15) sont munis de connecteurs qui s'adaptent l'un à l'autre (14, 16). Si, en raison de leur usure par exemple, les connecteurs (14, 16) doivent être remplacés, l'échange de l'unité de traversée (9) et de l'élément externe (15) se fait sans intervention chirurgicale ni traumatisme pour le patient.
