In Focus

 


Transit-Time Flow Measurement Improves Endarterectomy Outcomes

Over 120,000 carotid endarterectomies are performed each year in the United States. The value of flow measurement in these procedures has been documented in several medical journals. A sterile tubing Flowsensor placed on a Javid or Pruitt/Inahara shunt safeguards brain perfusion during the procedure.  Perivascular flow measurements at the conclusion of the procedure may identify low or turbulent flow caused by a correctable technical error.  More >

Transonic receives NIH SBIR grant: “Pediatric Cardiac Monitor for Extracorporeal Life Support"

The Transonic HT110 Flowmeter has long been an essential component of pediatric ECMO systems. Under the new grant, Transonic will develop a non-invasive monitor for measuring cardiac output (CO) to assist in weaning small pediatric patients from cardiopulmonary bypass (CPB) after open heart surgery in the operating room and from ECMO in the ICU setting.

The NIH scientific review states:

"There is no clinically available method to quickly and reliably assess cardiac function at the end of CPB for pediatic patients.  This proposal has the potential to address this need...The investigative team is excellent."

 

 

Product Updates

 

EC-IC probes now available in Asia and Europe

At this time these probes are available in 16-use versions in the following sizes: 3mm, 4mm, and 6mm.

HQC flash Autoclavable Flowprobe Line Expanded

Customers with HT313 Flowmeters were restricted to just cardiac probes if they wanted to be able to use steam sterilization. That has now changed. Effective June 1, the HQC flash steam sterilizable Flowprobe line has been expanded to include both vascular probes and probes for Carotid Endarterectomies.

Please Contact Us today to inquire about the new Flowprobes.

Powerful Conclusion

"Flow reduction of more than 50% of baseline values significantly predicts ischemic complications. The innovative role of intraoperative flowmetry is that it consents serial quantitative recordings, corroborating or contradicting subjective surgeon assessment about vessel flow integrity. Intraoperative quantitative cerebral blood flow monitoring is a safe and useful technique, fast, easy to perform and to repeat. Moreover, flowmetry-assisted aneurysm clipping offers the surgeon useful hemodynamic information during clipping procedures, allowing safer clip placement, especially in the repair of complex or broad-based cerebral aneurysms."
