Abstract

A telemetry coil arrangement for the telemetric reception of transmitted signals, in particular in cardiologic implants, comprises coils of varying diameters and numbers of windings suited thereto.

Claims

1. A telemetry coil arrangement for an inductive reception of transmitted signals comprising two or more coils spaced in a direction of reception, wherein at least two coils (1′

, 2′

, 5, 6, 5′

, 6′

, 8, 9, 10, 11) have varying diameters and numbers of windings suited to said varying diameters.

2. A coil arrangement according to claim 1, wherein at least three coils (5, 6, 5′

, 6′

) of at least two different diameters are provided.

3. A coil arrangement according to claim 2, wherein two pairs of coils (5, 6, 5′

, 6′

) form two coil systems (WS1′

, WS2′

) having a pair of smaller coils (5, 6) to be put in circuit in opposite directions and a pair of greater coils (5′

, 6′

) also to be put in circuit in opposite directions, both coil systems (WS1′

, WS2′

) being individually activable.

4. A coil arrangement according to claim 1, wherein said coils (5, 6, 5′

, 6′

, 9, 10, 11), in dependence on parameters of reception, are individually interconnectable to form combinations of coils.

5. A coil arrangement according to claim 4, wherein two coaxial coils (9, 10) spaced in the direction of reception and having an identical number of windings and diameter are provided as a basic pair of coils, to which at least two auxiliary coils (8, 11) of at least one of a varying number of windings and of a varying diameter are individually connectable.

6. A coil arrangement according to claim 1, wherein at least three coils are connectable to form at least two different coil systems.

7. A telemetry coil arrangement for an inductive reception of transmitted signals comprising two or more coils spaced in a direction of reception, wherein the coils having identical diameters are put into circuit asymmetrically.

8. A coil arrangement according to claim 7, wherein said coils (5, 6, 5′

, 6′

, 9, 10, 11), in dependence on parameters of reception, are individually interconnectable to form combinations of coils.

9. A coil arrangement according to claim 7, wherein two coaxial coils (9, 10) spaced in the direction of reception and having an identical number of windings and diameter are provided as a basic pair of coils, to which at least two auxiliary coils (8, 11) of at least one of a varying number of windings and of a varying diameter are individually connectable.

10. A coil arrangement according to claim 7, wherein at least three coils are connectable to form at least two different coil systems.
