Beijing "TV Clinic" Features Transonic Intraoperative Flow Measurements at Anzhen Hospital, a Transonic Center of Excellence, Ithaca, NY, April, 2004
During the International Cardio Vascular Meeting in Beijing China in April
2004, Beijing TV presented a program April 17 entitled "TV Clinic." The 40-minute program showed live coronary artery bypass grafting (CABG) surgery performed at
Anzhen Hospital in Beijing. During the surgery, the Transonic Surgical Flowmeter (HT313) was used to assess graft patency and document graft flows. View Full Article

Dr. Bruce Mindich, Chief of Cardiac Surgery at the Valley Hospital, Ridgewood, NJ will present the following poster "Reduction of Technical Graft Problems Using Ultrasonic Flow Measurements," the the 3rd International Meeting of the 10th Anniversary of the Onassis Cardiac Surgery Center in Athens, Greece, April 10-13, 2003.
The presentation outlines the success that surgeons at Valley Hospital, a
451-bed community hospital in Ridgewood, NJ, have experienced in reducing technical problems in over 1,000 CABG cases by using the Transonic flowmeter to measure flows in
bypass grafts following anastomosis. The team concludes: "The intraoperative use of flow measurements provide invaluable information in a timely, accurate,
cost-effective manner allowing for the surgical correction of a surgical problem. This has significantly reduced complications related to early technically induced graft
failure. In an era of rapidly changing surgical; techniques this provides documentation of the sine-qua-non of the operation: patency."

Transonic Systems Introduces Autoclavable "flash" Flowprobes
- March-August 2002
Transonic Systems takes the flowprobe engineering one step further by introducing the first autoclavable
flowprobes. The reusuable steam sterilizable flowprobes are available in sizes 2, 3, & 4 mm, in two styles: one with an elongated handle for ease of use in coronary
artery bypass grafting surgery, and another shorter handle style designed for vascular surgery but which can be used interchangeably. The flowprobes are also sterilizable
by standard cold EO or STERRAD. Click here for views of the new flowprobes

Transonic Systems Publishes Flow-based Intraoperative Graft
Patency Assessment Handbook
- April 2002
Available on this website is the 80-page handbook which presents transit time ultrasound for assessment of the patency
of coronary bypass grafts during on-pump or off-pump CABG. The handbook includes the physiology behind the flow measurements, the protocol for making the measurements,
waveforms from over 80 representative grafts, case studies and an appendix of measurement modalities, technology and references.

Transonic Systems Participates in Florida, History- Making Minimally Invasive Heart Bypass Surgery
AUGUST 20, 1999, ITHACA, NY
Transonic Systems' intraoperative flow measurements used to confirm the patency of coronary anastomoses were part of the first endoscopic, robot-assisted, coronary artery bypass grafting (CABG) surgery at Sarasota Memorial Hospital, Sarasota, FL. The surgery was performed using Computer Motion's Zeus™ Robotic Surgical System which requires an incision smaller than the diameter of a pencil to repair diseased heart arteries.
With the Zeus™ system the surgeon sits at a
console where he or she can view the operative site in 3-D or 2D. One robotic arm of the three arm system is used to provide voice-controlled visualization of the
endoscopic surgical field. The other two arms are used to manipulate surgical instruments or the flowprobe via handles that resemble conventional surgical instruments.
When the surgeon has completed a coronary graft anastomosis, he or she positions the Transonic flowprobe around the graft to record the blood flow through the graft. An
acceptable flow reading supported by an expected flow waveform from a flowmeter print-out assures the surgeon that the anastomosis is successful.
The United States Food and Drug Administration
(FDA) recently gave Computer Motion, the Santa Barbara, CA maker of the Zeus™ Robotic Surgical System (www.ComputerMotion.com)
approval for an extension of its Phase I Investigational Device Exemption (IDE) study. As part of the extended study, 10 cases using the Zeus™system will be performed
at both Sarasota Memorial Hospital and Medical City Hospital of Dallas. Fourteen robot assisted CABG surgeries which included Transonic flow measurements have taken place
at the Penn State Geisinger Health System' s Milton S. Hershey Medical Center. As a result, Transonic graft flow measurements were incorporated into the surgical protocol
submitted to the FDA for the extended multi-center study.
Transonic Systems, a pioneer and global leader
in flow measurement technology, received FDA clearance for intraoperative flow measurements over a decade ago. Its flow measurement systems are currently used in leading
institutions throughout the world.
