Conformal antenna for implantable medical device and implantable medical device with such antenna
First Claim
1. An implantable medical device, comprising:
- a housing having an interior surface having a generally tubular cross-section with a longitudinal axis, said housing having a lateral portion of a segment of said tubular cross-section along said longitudinal axis;
an antenna within the housing, the antenna comprising;
a bobbin within the housing, the bobbin having a first side and a second side opposite said first side, wherein the first side is nearer to the interior surface of said housing than that of the second side; and
a coil wound around said bobbin, wherein said wound coil defines a winding axis extending from the first side of the bobbin to the second side of the bobbin and orthogonal to said longitudinal axis of said tubular cross-section, said coil having a greater number of complete turns proximate said second side of said bobbin than proximate said first side of said bobbin, with said coil having a cross-sectional shape selected for a space between said bobbin and said interior of said housing in said lateral portion of said segment of said tubular cross-section along said longitudinal axis of said housing.

Abstract
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.

15. An implantable medical device comprising:
-
a housing having an interior surface having a generally tubular cross-section with a longitudinal axis, said housing having a lateral portion of a segment of said tubular cross-section along said longitudinal axis; device componentry within the housing; and an antenna within the housing, the antenna comprising; a bobbin within the housing, the bobbin having a first side and a second side opposite said first side, wherein the first side is nearer to the interior surface of said housing than that of the second side; a coil wound around said bobbin, wherein said wound coil defines a winding axis extending from the first side of the bobbin to the second side of the bobbin and orthogonal to said longitudinal axis of said tubular cross-section, said coil having a greater number of complete turns proximate said second side of said bobbin than proximate said first side of said bobbin, with said coil having a cross-sectional shape selected for a space between said bobbin and said interior of said housing in said lateral portion of said segment of said tubular cross-section along said longitudinal axis of said housing; and at least one electrode positioned on said second side of said bobbin, wherein the at least one electrode electrically couples said coil to said device componentry.
