NJIT Receives Patent Today for New Shunt To Aid Brain-Injured Patients

NJIT Professor Gordon Thomas and NJIT Research Professor Reginald Farrow, both in the department of physics, and NJIT alumnus Sheng Liu, formerly a doctoral student of both researchers and now an engineer at a biotech company, were awarded a patent today for the NJIT SmartShunt™, a unique device to help patients with brain injuries. 

The patent, entitled “No Clog Shunt Using a Compact Fluid Drag Path” (US Patent Number 8,088,091), discloses a device that enables the non-invasive wireless monitoring of both the extremely slow flow of cerebrospinal fluid as well as tiny changes in pressure in a shunt that drains  fluid out of the brain.   Ordinary shunts are commonly used by patients suffering from severe excess pressure in the brain due to hydrocephalus or brain injury. 

    “A serious problem with shunts is that they may malfunction or become obstructed.  The symptoms include a severe headache, but can be confusing, particularly when patients are small children,” said Thomas.  Such uncertainty can lead to the performance of unnecessary and unpleasant surgical procedures or, alternatively, to the postponement of what could be life-saving medical interventions. 

“The technology will enable patients and physicians to determine whether cerebrospinal fluid flow is in fact, impaired,” added Farrow.  The device will also allow those involved to determine better what medical procedures should be performed

The NJIT SmartShunt™ includes a set of components that are geared toward reducing the potential for shunt obstruction.  It is designed to have a lifetime of more than a decade because it needs no internal power.    "The SmartShunt™ will also be a valuable new tool for research into what extent diet, motion and medication of patients can improve the pressure and flow of the fluid in the brain," Thomas added. 

The NJIT team has been working on this device since September 2004 with grants from New Jersey Commission on Science and Technology and most recently from the National Institutes of Health. 

One of the nation's leading public technological universities, New Jersey Institute of Technology (NJIT) is a top-tier research university that prepares students to become leaders in the technology-dependent economy of the 21st century. NJIT's multidisciplinary curriculum and computing-intensive approach to education provide technological proficiency, business acumen and leadership skills. With an enrollment of more than 10,000 graduate and undergraduate students, NJIT offers small-campus intimacy with the resources of a major public research university. NJIT is a global leader in such fields as solar research, nanotechnology, resilient design, tissue engineering, and cyber-security, in addition to others. NJIT ranks 5th among U.S. polytechnic universities in research expenditures, topping $110 million, and is among the top 1 percent of public colleges and universities in return on educational investment, according to PayScale.com.
