An implantable medical device (IMD) comprises a plurality of deep tines configured to be advanced into a septum of a heart of a patient in different directions that are not parallel to a longitudinal axis of the implantable medical device, wherein each deep tine of the plurality of deep tines is configured to deliver cardiac pacing to cardiac tissue distal to a chamber of the heart in which the IMD is implanted, and one or more shallow electrodes engageable with the septum, wherein the one or more shallow electrodes are configured to deliver cardiac pacing to the chamber of the heart in which the IMD is implanted.

Multi-electrode implantable medical device (IMD)

An antenna structure for an implantable medical device (IMD) is provided including a lower dielectric biocompatible antenna portion positioned on a body side of the structure and a high dielectric portion including at least one dielectric substrate having a high dielectric constant positioned on a device side of the structure. The biocompatible antenna portion is derived from an antenna layer, a biocompatible surface layer, and at least one layer of biocompatible dielectric material (e.g., high temperature cofire ceramic (HTCC) material) that provides a matching gradient between the antenna and the surrounding environment. The high dielectric portion may include at least one layer of low temperature cofire ceramic (LTCC) material. The high dielectric portion may be bonded to the biocompatible antenna portion or cofired with the biocompatible antenna portion to form a single bilayer monolithic antenna structure having a lower dielectric HTCC biocompatible antenna portion and a high dielectric LTCC portion.

High dielectric substrate antenna for implantable miniaturized wireless communications and method for forming the same

A telemetry antenna for an implantable medical device includes one or more segments having a non-linear configuration. In some embodiments, the non-linear configuration provides an antenna having a greater antenna length than the linear lengthwise dimension of the antenna structure. In some embodiments, the non-linear configuration includes a plurality of trapezoidal unit structures.
