Definitions
- the invention relates to an implant for performing intracorporeal measurements according to the preamble of claim 1.
- a sensor device for pressure measurement and / or temperature measurement and a telemetry unit with an inductive coil, the windings of which are applied to the support film, are arranged on a flexible support film.
- the sensor device and the telemetry device are electrically connected to one another.
- the carrier film and the devices and components arranged thereon are encapsulated in a silicone covering.
- the object of the invention is to provide an implant of the type mentioned at the outset, which can be folded or bent in a stress-free manner, in particular in the area of inductive coil turns.
- the turns of the inductive coil which are formed by at least one metallized flexible plastic band, are arranged in the encapsulation material of the casing without a strap.
- the encapsulation material encompasses the turns on all sides.
- the wrapping material thus fulfills the carrier function.
- the turns of the coil are kept at an electrically insulating distance from one another by the covering material.
- a filling material other than the encapsulation material can also be used as a spacer filling material between the coil turns.
- Figure 1 is a plan view of the arrangement of the inductive coil and sensor device in one embodiment.
- FIG. 2 schematically shows a sectional, enlarged representation through parts of the implant shown in FIG. 1, only some of the coil turns and part of the sensor device being shown;
- FIG. 3 different manufacturing steps of the implant shown in Figs. 1 and 2.
- the implant shown in FIGS. 1 and 2 contains, in a covering 1 (shown in black in FIG. 1, shown in FIG. 2 with continuous and dotted hatching), for example made of silicone, a sensor device 2 and an electrically connected inductive coil 4.
- Sensor device 2 contains all the components required for measurement, such as pressure sensor and / or temperature sensor, and a telemetric processing circuit to convert the measurement signals into a signal form suitable for telemetry.
- the casing 1 is designed such that an acting pressure is passed on to the pressure sensor through the casing, which is preferably made of silicone.
- the coil 4 consists of one or more spirally wound turns 3, each turn 3 being formed by a plastic strip 5 covered with a metallization 6.
- the metallization 6 is preferably made of a noble metal, for example gold, and the plastic band 5 is preferably made of polyimide.
- the turns 3 of the inductive coil 4 are encompassed on all sides by the encapsulation material of the casing 1.
- another filler material e.g. B. a foldable acrylate or the like may be provided.
- the envelope 1 thus forms both the carrier for the coil turns and the spacer between the individual coil turns.
- a continuous carrier film on which the coil turns are applied is not required in the invention.
- the coil turns 3 are passed through the encapsulation material of the casing 1 in an isolated manner. At the spiral ends of the coil turns 3 there are contacting points 9, 10 at which the coil 4 is electrically connected to the sensor device 2.
- the thickness of the plastic band 5 can be 10 ⁇ m, for example.
- the thickness of the metallization 6 can be 5 to 120 ⁇ m.
- the plastic material of the film 7 is then removed between the metallizations by suitable solvents, so that turns 3 of the coil, which consist of the plastic tape 5 and the metallization 6 located thereon, remain on the base 8 (step B).
- the coil turns 3 and the sensor device 2 likewise subsequently introduced into the casting mold (step C) are then encapsulated, for example by molding.
- a material other than the encapsulation material can also be introduced as spacer filling material between the coil turns 3.
- the partially encapsulated implant of FIG. 2C is then detached from the base 8 and the still free side of the implant is also encapsulated with the encapsulation material by molding, so that the implant shown in FIGS. 1 and 2 is produced.
- the implant is preferably used for telemetric intracranial pressure measurement, in particular epidural intracranial pressure measurement as is known for example from DE 101 56 469 AI, or for telemetric intraocular pressure measurement as is known for example from DE 199 45 879 AI.
- the implant forms the intracorporeal, telemetric measuring device.
