Dynamic telemetry link selection for an implantable device

Dynamic telemetry link selection for an implantable device description/claims

This application is a continuation of U.S. patent application Ser. No. 10/914,638, filed Aug. 9, 2004, which is incorporated herein by reference in its entirety.

This document is related to U.S. patent application Ser. No. 10/914,499, entitled “TELEMETRY SWITCHOVER STATE MACHINE WITH FIRMWARE PRIORITY CONTROL,” filed Aug. 9, 2004 by Quiles et al. (Attorney Docket 00279.772US1) and is incorporated herein by reference.

This document is related to U.S. patent application Ser. No. 10/914,641, entitled “SECURE REMOTE ACCESS FOR AN IMPLANTABLE MEDICAL DEVICE,” filed Aug. 9, 2004 by Quiles (Attorney Docket 00279.771US1) and is incorporated herein by reference.

This document pertains generally to implantable devices, and more particularly, but not by way of limitation, to telemetry link selection for an implantable device.

Implantable devices typically communicate using an inductive telemetry link. Inductive telemetry refers to communications involving a loop antenna of an external device inductively coupled with a loop antenna of the implantable device.

Communication inefficiencies associated with inductive telemetry impair the delivery of medical care. Inefficiencies include low bandwidth and limitations associated with the requirement for close physical proximity. Improved telemetry systems are needed.

In the drawings, which are not necessarily drawn to scale, like numerals describe substantially similar components throughout the several views. Like numerals having different letter suffixes represent different instances of substantially similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed herein.

FIG. 1 includes an illustration of an implantable device in communication with an external device.

FIGS. 2, 3, 4 and 5 include illustrations of flow charts for selecting a physical link.

The following detailed description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments, which are also referred to herein as “examples,” are described in enough detail to enable those skilled in the art to practice the invention. The examples may be combined, other examples may be utilized, or structural, logical and electrical changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
