Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0030] The present invention will be described in further detail below in conjunction with examples and specific implementation methods.

[0031] like Figure 1-Figure 3 As shown, an implantable medical device includes:

[0032] case;

[0033] at least two radio frequency antennas disposed outside and adjacent to the housing, each RF antenna configured to receive RF signals transmitted to the IMD from a remote RF signal source , wherein the RF antennas are separated from each other by a distance of at least one quarter of the wavelength of the center frequency;

[0034] RF communication circuitry disposed within the housing and configured to selectively receive RF signals received by one or more of the RF antennas, wherein the RF communication circuitry is configured to ope...

Abstract

The invention discloses implantable medical equipment which comprises a shell, at least two radiofrequency antennas, RF (radiofrequency) communication circuits and antenna switches. The implantable medical equipment has the advantage that the purposes of preventing multi-path fading or distortion of the communication antennas, preventing repeated reflection of transmission signals between radiofrequency transmitters and radiofrequency receivers and guaranteeing the signal transmission accuracy can be achieved.

Description

technical field [0001] The present invention relates to implantable devices, and more particularly to implantable devices including multiple communication antennas. Background technique [0002] Various devices have been developed for implantation in the human body for various health-related treatments and / or monitoring. These devices, commonly referred to as implantable medical devices (IMDs), include cardiac pacemakers, cardioverter defibrillators, cardiac stimulators, and various physiological stimulators, as well as nerve, muscle, and deep brain stimulators, various Various types of physiological monitors and drug delivery systems, etc. Some IMDs contain varying amounts of electronic memory, which can be used not only to operate the stored device and control software, but also to store various patient- and device-related data. In addition, some of the same IMDs may include signal processing and telemetry circuitry that may transmit some or all of the data stored in mem...
