Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N 1372
US Classification:
607 60, 607 32, 128901, 3405727, 3405731
Abstract:
An apparatus and method for enabling radio-frequency communications with an implantable medical device utilizing far-field electromagnetic radiation. Such radio-frequency communications can take place over much greater distances than with inductively coupled antennas.

Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
H01Q 140
US Classification:
343873, 343872, 343741, 607 60, 128903
Abstract:
An apparatus and method for enabling far-field radio-frequency communications with an implantable medical device in which an antenna is embedded within a dielectric around the periphery of the device. Such a circumferential antenna saves space while still permitting far-field telemetry over a desired range of frequencies.

International Classification:
A61N 102
US Classification:
607 60, 607 37, 607 32, 607 36
Abstract:
An apparatus and method for enabling far-field radio-frequency communications with an implantable medical device in which an antenna is embedded within a dielectric compartment of the device. A helical antenna may be employed to save space while still permitting far-field telemetry over a desired range of frequencies.

Passive Telemetry System For Implantable Medical Device
William R. Mass - Maple Grove MN, US Jeffrey A. Von Arx - Minneapolis MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N001/02
US Classification:
607 60, 128903
Abstract:
A telemetry system enabling radio-frequency communications between an implantable medical device and an external device which requires minimal power consumption by the implantable device. The implantable device uses an antenna tuning circuit to vary the impedance of an antenna and phase modulate a carrier signal reflected back to the external device with digital message data.
