CONFORMAL ANTENNA FOR IMPLANTABLE MEDICAL DEVICE AND IMPLANTABLE MEDICAL DEVICE WITH SUCH ANTENNA AND METHOD OF MAKING SUCH ANTENNA

摘要

System and method for making an antenna. An implantable medical device has a housing, a bobbin and a coil. The housing has an interior generally tubular cross- section with a longitudinal axis, the housing having a lateral portion of a segment of the tubular cross-section along the longitudinal axis. The bobbin has a first side nearest to the interior of the housing and a second side opposite the first side. The coil, wound around the bobbin on a winding axis orthogonal to the longitudinal axis of the tubular cross-section, has a greater number of complete turns proximate the second side of the bobbin than proximate the first side of the bobbin, with the coil having a cross-sectional shape selected for a space between the bobbin and the interior of the housing in the lateral portion of the segment of the tubular cross-section along the longitudinal axis of the housing.
