Washington University surgeons are
implanting an investigational left ventricular
assist device (VAD) called the Jarvik 2000
FlowMaker. The size of a C battery, it takes
up very little space inside the chest and can
be implanted through a small incision.
The device reduces the risk of clots and
allows patients to adjust the flow depending
on their activities. Robert Jarvik, MD, a
pioneer in artificial hearts and assist devices,
was present in the operating room at
Barnes-Jewish Hospital for the placement
of the first Jarvik 2000 VAD.

Washington University neurosurgeon
Neill Wright, MD, has developed a technique
that is now a standard treatment worldwide
for patients with instability of the
upper cervical spine. Beginning in the 1990s,
surgeons used techniques called transarticular
fixation to stabilize the spine; these were
demanding for the surgeon to perform
and carried a significant risk of injury to
vertebral arteries and stroke. Wright’s
procedure, called translaminar fixation,
stabilizes the spine and avoids those risks.

A new imaging technique could speed the detection of cancer. Called photoacoustic tomography, the technique uses light and sound to make the invisible become visible,
replacing X-ray’s gray images with color images. Washington University researcher Lihong Wang, PhD, and other scientists at the Siteman Cancer Center are moving four
applications into clinical trials: visualizing lymph nodes important in breast cancer staging, monitoring early response to chemotherapy and imaging melanomas and the gastrointestinal tract.
