BENT LOOP ANTENNA FOR IMPLANTABLE MEDICAL DEVICES

摘要

An implantable medical device can include a device housing including a circuitry module and a header including a header core defining a bore configured to receive a distal end of a lead, an antenna, and a header shell disposed around the header core and the antenna. The antenna can be a closed loop antenna and arranged such that the antenna is positioned within two planes to maximize the area within the closed loop to increase the radiation characteristics of the antenna.

主权项

1. An implantable medical device, comprising:
a device container including an electronic module within the device container; a header, the header including:
a header core having a first header surface side, a second header surface side opposite the first header surface side, and a superior header surface side extending between the first and second header surface sides;a closed loop antenna disposed in two different planes, the closed loop antenna, including:
a first portion positioned toward a first end of the header, the first portion including a first section extending adjacent to the first header surface side and a second section extending adjacent to the superior header surface side;a second portion positioned toward a second end of the header, the second portion including a third section extending adjacent to the first header surface side, and a fourth section extending adjacent to the superior header surface side; anda third portion connecting the first portion and the second portion; anda header shell disposed around the header core and attached to the device container.
