Critical Limb Ischemia

Critical Limb Ischemia

Affecting over 30 million patients worldwide, Critical Limb Ischemia (CLI) is a growing unmet need that results in over 40,000 amputations in the US alone each year. Existing interventions lack durability, requiring a repeat intervention as soon as 3 months later in the majority of CLI patients. There is no FDA approved technology to improve procedure durability below-the-knee. SoundPipe is developing a novel, intravascular ultrasound platform to address this unmet need.


Our Platform

The Guidance by Ultrasound Imaging and Delivery Enhancement of Therapeutics (GUIDE-Tx) platform is an intravascular ultrasound system that using a catheter mounted ultrasound device to image the vessel and improve drug delivery. This will allow interventionalists to see the diseased vessel, treat the diseased vessel, and verify treatment with one platform. Currently under development, our patented technology will revolutionize the treatment of CLI.
See the extent of disease in the vessel
Treat the diseased vessel by “painting” with drug where needed
Verify treatment with real-time imaging


What are doctors telling us about GUIDE-Tx?

As part of the ICorps@NIH, our team interviewed over 55 doctors to understand how GUIDE-Tx could best help their patients. Here is some of the feedback we received.

“I think you have something very exciting that may help our field and patients”

“That would be amazing!”

“Unbridled enthusiasm.”

“New approaches to interventions such as this could have some societal benefits as well.”
