Current Programs
Breast Tumor Characterization
J&W Medical proposes a new system concept for highly improved early diagnostic
ultrasound detection and characterization of breast cancer. To date, there has
been little progress in estimating volume, size and shape of breast tumors in a
clinical environment, and in relating these identifiers to tissue pathology. The
proposed system (based on
US patent 6,585,647) will be capable of providing a clinically significant
measure of the size, shape, volume and composition of breast tumors down to 1 mm
in size. This represents a five-fold improvement over the lowest resolution
achievable through current X-Ray mammogram techniques, and a three-fold
improvement over current MRI capabilities -- neither of which currently provide
lesion volumetric estimates or tissue characterization data.

Bone Quality Assessment (BQA)
Bone quality assessment (BQA) is based on the established technique of
Quantitative Ultrasound, which leverages a well-known collection of metrics to
extrapolate information about tissue health. J&W Medical proposes a system
(based on
US patent 6,213,958) that will support the ongoing assessment of bone health
against personal baselines, and also serve as an early indicator of metabolic
bone disease. This technology uses nonlinear acoustics to stimulate bone tissue
and produce acoustic emissions, and will support the creation of an acoustic
fingerprint database of specific pathological bone conditions, such as
osteoporosis and bone cancer.

Bone Healing
In recent years, ultrasound has overtaken competing electromagnetic technologies
(PEMF, CMF and capacitive coupling) for market share in the bone healing space.
The Smith and Nephew Exogen device is rapidly becoming the treatment of choice
for delayed union (take longer than 270 days to heal) or non-union (never heal)
fractures. The biochemical basis for radiation pressure-induced bone healing is
not perfectly understood, however, and the current Exogen signal is not
necessarily optimized for bone healing applications. J&W Medical is in the
process of developing a patent for an innovative new signal that early-stage
research suggests will significantly enhance the efficacy of ultrasonic bone
healing.

Spinal Fusion Healing
Spinal fusion is a critical element in many spinal surgical procedures. Of the
more than 350,000 spinal fusion surgical procedures that occur annually in the
United States, approximately 40% become delayed union or non-union fractures.
The incidence of delayed and non-unions contributes significantly to the
morbidity associated with spinal surgery, particularly of the lumbar and
cervical spine. These are excellent candidates for accelerated healing with
therapeutic ultrasound, which has been proven to be more effective than
electromagnetic modalities (PEMF, CMF, capacitive coupling) in bone healing
applications, and which is currently not used for spinal fusion healing due to
technical limitations. J&W Medical is in the process of developing a patent for
an innovative new signal that early-stage research suggests will be clinically
effective for spinal fusion ultrasonic healing.
