Abstract

An implantable electronic medical device has a device body and a header placed thereon, and includes a telemetry assembly for signal transmission to and/or from outside the body of a patient when the device is implanted, in particular for the wireless bidirectional communication. A transmit/receive antenna, which is physically formed of an elongated conductor and arranged in the region of the header and which is configured so as to have a form fit with the outer contour of at least a portion of the header, and is fixed thereby in the header, is at least largely assigned to the telemetry assembly. A first section of the conductor has a spring elastic design and forms a bracket or clamp. The bracket embraces a connector in the header. There is also described a transmit/receive antenna of a telemetry assembly of an implantable electronic medical device.

First claim

1 . An implantable electronic medical device, comprising:
a device body, a header disposed on said device body, and a telemetry assembly for signal transmission to and/or from outside a body of a patient when the device is implanted; a transmit/receive antenna connected to said telemetry assembly, said transmit/receive antenna being an elongated conductor arranged in a region of said header; said transmit/receive antenna being configured to form-fittingly engage an outer contour of at least a portion of said header and to be fixed in said header; said elongated conductor having a first section forming a bracket with a spring-elastic design configured to embrace a connector in said header.

2 . The device according to claim 1 , wherein said elongated conductor has a second section arranged on an upper face of a connection block in said header, said connection block comprising the connector.

3 . The device according to claim 2 , which comprises at least one connecting conductor, which has an electrically conductive connection with the connector, arranged on a side of said connection block.

4 . The device according to claim 3 , wherein said upper face of said connection block and said side of said connection block include a substantially right angle.

5 . The device according to claim 2 , wherein said first section of said conductor is angled with respect to said second section of said conductor, which is arranged on said upper face of said connection block.

6 . The device according to claim 1 , wherein said elongated conductor is a ribbon-shaped conductor.

7 . The device according to claim 6 , wherein a ratio of a width to a height of said ribbon-shaped conductor is 4:1 or more.

8 . The device according to claim 7 , wherein the ratio is more than 8:1.

9 . The device according to claim 1 , wherein said transmit/receive antenna is a device selected from the group consisting of a bent stamping, a 3D printed sintered part, and a metal injection molded part.

10 . The device according to claim 2 , wherein said transmit/receive antenna is arranged in said second section of the conductor, and said transmit/receive antenna is formed with a meander-shaped progression arranged in a plane on said upper face of said connection block in a majority of an extension of said transmit/receive antenna.

11 . The device according to claim 10 , which comprises reinforcement bridges in meander bends at least in a sub-section of said meander-shaped progression.

12 . The device according to claim 1 , wherein said bracket is an Ω-shaped bracket.

13 . A transmit/receive antenna of a telemetry assembly of an implantable electronic medical device, the medical device having a device body and a header disposed on said device body, the transmit/receive antenna comprising:
an elongated conductor configured to form a form fit with a outer contour of at least a portion of the header, and to be fixed thereby in the header; said conductor having a first section with a spring elastic design forming a bracket configured to embrace a connector in the header.

14 . The transmit/receive antenna according to claim 13 , wherein said first section of said conductor is angled with respect to a second section of said conductor.

15 . The transmit/receive antenna according to claim 13 , wherein said bracket is an Ω-shaped bracket.
