Definitions
- the invention relates to a medical implant for implantation in a Outside of the skull, especially in the area of the planum mastoid Bone bed is suitable and has a hermetically sealed housing, in which an electronic arrangement and possibly further components or Assemblies are housed.
- Implants of this type are, inter alia, from DE 39 18 086 C1 and DE 39 18 329 A1 known.
- Size especially the depth, of the bone bed must be kept as small as possible and is limited by the anatomical conditions, and that on the other hand a An unwanted protrusion of the housing over the outer edge of the bone bed Bulging of the skin over the implant would result and therefore as far as possible is possible to avoid.
- the problem worsens the larger the volume requirement in the housing, for example because of the complexity of the electronics to be accommodated or other components, such as a power supply unit or parts of one such unity.
- the flexibility of the flap adapts to the shape of the skull, is however with regard to a risk of breaking the connections between those in the Rag added components and the components problematic in the Titanium case are housed.
- the thickness of the flexible flap is that is maximum permissible so that the skin over the rag does not interfere bulges, so severely restricted that this solution also for many reasons of space Implant components.
- the invention has for its object a medical implant of the beginning to create the type mentioned, which allows, given a given size, in particular depth, the bone bed to provide a particularly large housing volume, while at the same time, a projection of the housing completely over the outer wheel of the bone bed or at least largely avoided.
- a medical Implant that is intended for implantation in one on the outside of the skull, in particular in the area of the planum mastoid, trained bone bed is suitable and has a hermetically sealed housing in which an electronic arrangement and, if necessary, further components or assemblies are accommodated Housing is provided in at least one level with at least one kink that is dimensioned such that a tangent to a plane perpendicular to the direction of buckling the bottom of the housing at one end of the housing with a tangent to the bottom of the housing at the other end of the housing forms an angle in the range of 5 ° to 25 °.
- the housing is preferably in the region of its middle third, in particular approximately in the middle, in at least one plane through an angle in the range of 5 ° to 25 ° kinked.
- the housing in at least to bend or bend a layer several times.
- the angle that the tangents to the bottom of the case on one and the other Forming the housing end together is preferably in the range of 7 ° to 15 °. As An angle of approximately 10 ° has proven particularly favorable.
- the largest dimension of the housing is in Range from 30 to 55 mm, and preferably in the range from 38 to 50 mm, while the direction of buckling is perpendicular to this largest dimension.
- the smallest dimension (thickness) of the housing is expediently in the range from 4 to 8 mm.
- the housing is advantageously rigid, which creates mechanical stresses the components housed therein and their mutual connections as far as possible be avoided.
- the housing can at least partly consist of ceramic material and in particular with a Ceramic housing part and a metal housing part.
- a housing training leads to a housing that is at least partially for electrical, magnetic and electromagnetic fields is transparent. This is essential if, for example a receiving and / or transmitting antenna is to be accommodated in the housing.
- the housing can also be a metal housing.
- a housing with a ceramic housing part and a metal housing part advantageous the kink near the meeting point of the ceramic housing part and metal housing part.
- an energy supply unit or the implantable part of such a unit and an electronics unit his.
- the implant can in particular be part of an at least partially implantable Hearing aid, in particular an active hearing aid for mechanical or electrical irritation of the inner ear, such as that described in DE 39 18 086 C1, DE 39 18 329 A1, DE 39 40 632 C1, DE 41 04 359 C2 and US Pat. No. 4,419,995 are known or are described in the older DE patent application 196 38 159.2.
- the invention is in no way limited to this. Rather, it is suitable in in the same way for any other implants in which the implantation site is Skull, especially in the area of the planum mastoid, comes into question. Examples of such implants, to name a few, are tinnitus suppression systems, Drug pumps and retinal stimulators.
- the illustrated implant 10 has a housing 11 with a ceramic housing part 12 and a metal housing part 13.
- the housing 11 is inserted into a bone bed 14, that on the outside 15 of a skull cap 16, in particular in the area of the Planum mastoid, is formed.
- the ceramic housing part 12 the receiving coil of an energy charging system for recharging an energy store of the implant.
- an energy charging system is from DE 41 04 359 C2 is known and therefore does not require any further explanation in the present case.
- the Metal housing part 13 can accommodate an electronic module that is connected to the receiving coil is in electrical connection and is fed from the rechargeable energy store.
- the electronics module can in turn be part of an active hearing aid for mechanical or electrical irritation to the middle ear.
- Such electronic modules can also trained in a conventional manner (see the references mentioned above) his.
- the housing 11 is in the region of its middle One-third kinked, the kink line 18 running perpendicular to the longitudinal dimension of the housing.
- the kink 18 is near the meeting point of the ceramic housing part 12 and Metal housing part 13.
- the kink is dimensioned such that in one to the direction of buckling vertical plane a tangent to the housing bottom 19 at one Housing end 20 with a tangent to the housing underside at the other housing end 21 forms an angle ⁇ in the range from 5 ° to 25 °.
- The is preferably Angle ⁇ about 10 °.
- the largest dimension of the housing 11, that is Longitudinal housing dimension can suitably be in the range of 30 to 55 mm, and the housing 11 can generally have a smallest dimension (thickness) in the range of 4 to 8 mm.
- One or more connecting cables 23 can be made from the hermetically sealed housing 11 be led out.
- a contact arrangement of the type known from DE 196 22 669 A1 can be provided, these Contact arrangement sits under a removable cover 25 of the implant 10.
- the aforementioned reception coil is shown schematically at 26 in FIG. 2.
- the coil 26 can additionally or instead also be used as a transmitter coil, for example around To transmit information from the implant to an extracorporeal receiving device.
- FIG. 4 shows a housing 11 'which is bent twice, while in FIG. 5 a curved one Housing 11 '' is illustrated. This is also a requirement for housings 11 'and 11' ' fulfilled that in a plane perpendicular to the direction of buckling a tangent to the underside of the housing 19 at one housing end 20 with a tangent to the housing underside at the other housing end 21 forms an angle ⁇ in the range from 5 ° to 25 °.
- the housing materials can be selected in a known manner.
- metallic materials come in particular titanium, titanium alloys, niobium, niobium alloys, cobalt-chromium alloys and stainless steels are considered, which are biocompatible and corrosion-resistant are.
- Suitable ceramic materials include aluminum oxide and boron nitride.
