Abstract

A system for programming an implantable medical device by means of an HTTP server located within the implantable medical device is provided. HTTP servers are capable of supporting web forms that are available in sizes below 50 kilobytes and may therefore be made small enough to fit within an implantable medical device. The implantable medical device may be an electrical stimulator, an infusion pump, a sensor, or any combination or multiple of these. The HTTP server communicates wirelessly with a web browser within a personal computer, a clinician's computer, or a remote control unit.

Implantable Medical Device Interface System and Method

Background & Summary

This invention relates to implantable medical devices such as electrical stimulators, drug infusion pumps, and implantable sensor systems such as spinal cord stimulators, pacemakers, and deep brain stimulators. Such implantable medical devices deliver therapy to patient by means of electrical stimulation, delivery of drugs to tissue within the body, or by sensing and responding to the levels of specific substances or activities within the body.

Current implantable medical devices are typically programmed using a specially designed remote control device that contains a computer and a radio or magnetic device to communicate to the implant. The computer contains a specific program designed to control and adjust the particular parameters of its respective implantable medical device. Patients wearing implantable medical devices use remote control devices to control the therapy delivered by the implantable medical device by adjusting the parameters (within a range predetermined during a fitting session with a clinician) of the implantable medical device.

Some of the remote control devices are capable of operating (controlling and adjusting the parameters of the implantable medical device) independent of a larger support computer. However, other remote control devices require a computer with more capabilities (typically a personal computer or clinician’s fitting station) to configure the remote control parameters and set the limits of the adjustability of such parameters for a patient using the remote control unit to control the therapy of the implantable medical device.

Often, clinician’s are required to stock specific hardware and software (such as a clinician’s fitting station or a clinician programmer) capable of interfacing with either the remote control device or the implantable medical device. Such software and hardware is expensive to obtain and maintain. Without this equipment and software, the clinician will be unable to offer assistant to a patient whose implanted device cannot be controlled without such software and hardware. Therefore, a need exists for a means for controlling and adjusting the parameters of an implantable medical device without the use of relatively costly and complex clinician hardware and software.

Some have attempted to meet this need. For example, U.S. Patent No. 6,577,901 discusses a network compatible radio frequency (RF) wireless link for medical device data management. Further, U.S. Patent No. 6,473,638 discusses the display of implantable medical device data using a graphical user interface on an external device.
