Meridian Medical Systems Improves Treatment
of a Critical Heart Condition
Using Microwave Technology
  AWR(R)
Software and TriQuint Foundry Process Make Company's Radiometer Development
a Painless Procedure
The story: Meridian Medical Systems
(MMS), founded by microwave industry veteran and IEEE Fellow Dr. Kenneth
Carr, uses the inherent characteristics of electromagnetic energy in
medical application to provide solutions that have eluded other technologies.
The company's latest product solves a problem in treating cardiac arrhythmia
(when the heart beats too slowly, too fast, or irregularly) using cardiac
ablation that selectively destroys tissue to ensure that the "signal"
controlling the heartbeat follows the proper path. It is essential that
the proper amount of tissue is destroyed, but previous solutions do
not provide real-time feedback about how much energy to apply because
their temperature sensors measure only the value in the tip, rather
than the tissue itself.A catheter developed by MMS simultaneously delivers
microwave radiation for tissue heating and directly senses the temperature
of the heart wall using a radiometer remote sensing device fabricated
as a microwave monolithic integrated circuit (MMIC). The MMIC was designed
using AWR's Microwave Office(R) high-frequency EDA software and transferred
to TriQuint Semiconductor's foundry using a process design kit (PDK)
developed jointly by AWR and TriQuint. The article details the process
as well as the technology developed by MMS and is available at

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
