MEDICAL DEVICE
EMBEDDED CONTROLLER
PROJECTS
Dave Wills, Inc. has been involved in many projects to design
stand-alone medical devices.
These devices include Radio Frequency (RF) generators, blood analyzers
and controllers for imaging systems. The devices must have a very low risk
of failure and endure the exhaustive testing and requirements of the
Federal Drug Administration.
Our embedded controller software
systems include custom real-time
operating systems, user interfaces, device drivers,
a power control algorithm, often a temperature control algorithm and
have external tools communications.
Shown here is a
Nebulizer or
atomizer. Dave Wills, Inc. designed the system, which
includes a small Application Specific Integrated Circuit (ASIC) embedded processor, and
designed the battery and charging components.
Dave Wills, Inc. participated
in the design of a Blood glucose monitor (not shown)
for use in the ICU. The Graphical User Interface
(GUI), internal communications systems, and system
initialization were designed.
RF generators deliver RF power to
ablate or burn off tissue. Examples of RF generator use in medical applications
are for surgical cutting and sealing or for removing fibroids and
tumors.
Another
application uses RF energy to create lesions
on heart muscle, preventing unwanted electrical
signals traversing the heart muscle and causing
fibrillation.
