Acoustic-Based Tissue Resuscitation

The technology

Market need

Current methods used to treat and prevent ischemia consist of intravenously-delivered pharmaceutical agents and invasive devices, such as the intra-aortic balloon pump. The ability to modulate blood flow easily and noninvasively is necessary for adequate treatment and prevention of ischemia.

Technology summary

This is a device to treat or prevent ischemia by rapidly increasing blood flow and, thereby, oxygen to tissues. The device delivers a low-frequency sound to the entire body or selected areas, which results in an increase in blood flow. The device is non-invasive and the effect can essentially be turned on and off. Moreover, this device could allow on-thefly programming and feedback when coupled with a method or technique which measures tissue oxygenation or blood flow. The apparatus is user-friendly and could be used by paramedics or in emergency departments, operating rooms, intensive care units, and in the home.
