Provisio SLT IVUS System Launched

May 21, 2024—Provisio Medical, Inc., developer of sonic lumen tomography (SLT) technology to provide real-time blood vessel measurements during vascular interventions, recently announced the completion of the first commercial clinical cases utilizing the Provisio SLT intravascular ultrasound (IVUS) system.

The first cases were performed by Robert Tahara, MD, at Allegheny Vein and Vascular in Bradford, Pennsylvania.

“This is an exciting new development in intraluminal measurement technology,” commented Dr. Tahara in the company’s press release. “It gives us a rapid, novel, and extremely precise way to get the size and contour of vessels, which is critical for the appropriate treatment of a patient with chronic and limb threatening ischemia.”

On April 25, the company announced FDA 510(k) clearance of the Provisio SLT IVUS system, which is designed to enable vessel lumen measurement and visualization simultaneously with guidewire support and delivery of radiopaque contrast agents.

Peter Schneider, MD, who is a member of the Provisio Medical Physician Advisory Board, stated in the press release, “We now have a catheter-based method of real-time vascular assessment that could improve upon our unique reliance on arteriographic imaging.”

According to the company, the Provisio SLT IVUS system consists of the SLT IVUS P1 system and the SLT IVUS support crossing catheter, which is an over-the-wire intravascular ultrasound catheter with an ultrasound transducer array at the distal end that also functions as a support crossing catheter. The information from the ultrasound signal is used similarly to sonar technology to measure vessel dimensions in real-time and measure the peripheral vessel’s flow lumen.
