Product catalog summary
Introduction
The VTI Endoscopic Doppler System (E-DOP) is a breakthrough tool designed to manage acute peptic ulcer hemorrhage by detecting subsurface blood flow, thus preventing rebleeding before it occurs. It is easy to use, economical, and does not require EUS equipment or training.

Specifications and Features
  • The system uses disposable Doppler probes for patient safety and reliability.
  • Probes are available for both upper and lower GI applications and can be used with channels 2.8mm or larger.
  • It allows endoscopists to map arterial courses within ulcer bases, target hemostatic therapy, and identify patients at risk for rebleeding.

Clinical Applications and Benefits
  • Doppler-guided endoscopic hemostasis significantly reduces recurrent bleeding rates in acute peptic ulcer hemorrhage.
  • Ulcers that remain Doppler positive after therapy are at higher risk for rebleeding.
  • The system aids in the diagnosis and treatment of gastric varices and other submucosal pathologies.

Procedures and Techniques
  • Combination therapies, such as epinephrine injection and thermal coagulation, are guided by Doppler signals to ensure effective treatment.
  • Hemoclips can be accurately placed using the Doppler "acoustic map" to occlude arteries.

Research and Studies
  • Studies demonstrate the utility of the Doppler probe in various applications, including gastric varices treatment and endoscopic submucosal dissection.
  • Prospective and randomized controlled studies show promising results for improving clinical outcomes in high-risk patients.

Expert Opinions
  • Dr. Richard C.K. Wong and Dr. Dennis M. Jensen highlight the system's ability to provide focused treatment and improve risk stratification beyond visual cues.

Ordering Information
  • Catalog numbers and descriptions for various components, including Doppler transceivers and probes, are provided for easy ordering.

The VTI Endoscopic Doppler System* (E-DOP) For endoscopic hemostasis, the Doppler probe has allowed us to provide focused treatment of the underlying artery because we can detect blood flow & location of the artery before treatment and confirm definitive endoscopic hemostasis and obliteration of the underlying arterial flow afterward by repeat Doppler examination. Our group is conducting prospective and randomized controlled studies which show promising results for the role of endoscopic Doppler in improving clinical outcomes of high risk patients with severe UGI & colon hemorrhage.” n easy to...
