Acute kidney injury is common in hospitalized patients, particularly those in intensive care units and older adults, and refers to a sudden episode of kidney failure or damage that happens within a few hours or days. It causes a build-up of waste products in the blood that can affect other organs, including the brain, heart, and lungs.
A respiratory dialysis system that was developed at the McGowan Institute for Regenerative Medicine Medical Devices Lab has been used to treat 16 COVID-19 patients, in conjunction with non-invasive or mechanical ventilation. The core technology developed at the Medical Devices Lab, was licensed to the spinout ALung Technologies, and ALung has designed and produced a clinically viable device, which is called the Hemolung® Respiratory Assist System (RAS).
In Pennsylvania and other U.S. states, one of the keys to safely reopening society amid the COVID-19 pandemic is providing sufficient testing so that new cases of the disease do not overwhelm the public healthcare system. University of Pittsburgh professors—led by McGowan Institute for Regenerative Medicine affiliated faculty member Wei Gao, PhD—are reimagining testing using a device that nearly every American owns — a smartphone.
Researchers at Carnegie Mellon University (CMU) and the University of Pittsburgh School of Medicine are developing a new, low-cost ventilator they say will address the ventilator shortage, both now and in the future, that has been made evident by the COVID-19 pandemic. The team includes McGowan Institute for Regenerative Medicine affiliated faculty member Keith Cook, PhD, a CMU professor of biomedical engineering. Dr. Cook, of CMU’s Biomedical Engineering Department, has expertise in advanced respiratory support, including the design and development of artificial lungs, liquid ventilation hardware and techniques, and animal models of lung disease.
A multidisciplinary team of researchers and clinicians, including McGowan Institute for Regenerative Medicine faculty member Peter Rubin, MD, FACS, Chair of the Department of Plastic Surgery, the UPMC Endowed Professor of Plastic Surgery, Director of UPMC Wound Healing Services, and Professor of Bioengineering at the University of Pittsburgh, is working on a low-cost negative pressure hood that can be used to protect medical staff during intubations and other situations where aerosol spray is likely from infected patients. Moreover, it can also help prevent spread in environments without a negative pressure room, such as the Emergency Department of a hospital. This apparatus is different and far advanced compared with static protection boxes which are only passive shields. What makes this new hood most remarkable is its active airflow and HEPA filtering.
A device designed at the McGowan Institute for Regenerative Medicine could help improve outcomes as a treatment for COVID-19 when used in conjunction with non-invasive or mechanical ventilation, and it recently received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration. Health records from a New York study showed that close to 90 percent of patients who were placed on mechanical ventilation did not survive. Some intensive care units are now considering mechanical ventilation as a last resort because of the complications and side effects associated with the process, and researchers believe this device could help.

Approximately one in every 125 babies in the U.S. is born with a congenital heart defect (CHD), making it the country’s most common birth defect. Heart valves developed for adults have been used on infants to treat CHDs, but the large devices sometimes require open heart surgery, presenting a severe risk to infants and young children. Additionally, infants and children grow quickly, but the artificial valve does not, resulting in repeated surgeries that increase risks.

Pelvic organ prolapse (POP) is a condition where the organs in the pelvis push against the vagina, creating a “bulge” that can extend outside of the body. It results from a weakening of the muscles and tissues that help support the pelvic organs. This disorder affects many women, but surgical treatments with polypropylene mesh – devices initially designed for hernia repairs, not vaginal use – often result in complications.

Chronic brain implants are long-term devices used to record brain activity or stimulate neurons with electrical pulses and are a crucial component of neuroprosthetics. The performance of these devices depends on the host tissue response, which is often inflammatory and results in device performance degradation. McGowan Institute for Regenerative Medicine affiliated faculty member Takashi Kozai, PhD, assistant professor of bioengineering at the University of Pittsburgh Swanson School of Engineering, was awarded an NIH R21 grant to improve device design by investigating the role of oligodendrocytes and oligodendrocyte progenitor cells in this process.
Researchers at Carnegie Mellon University have developed a low-cost 3-D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system. The researchers—Carnegie Mellon University (CMU) Materials Science and Engineering (MSE) and Biomedical Engineering (BME) Associate Professor Adam Feinberg, PhD, BME postdoctoral fellow TJ Hinton, PhD, and Kira Pusch, a recent graduate of the MSE undergraduate program—recently published a paper in the journal HardwareX that contains complete instructions for printing and installing the syringe-based, large volume extruder (LVE) to modify any typical, commercial plastic printer.
Implanted devices send targeted electrical stimulation to the nervous system to interfere with abnormal brain activity, and it is commonly assumed that neurons are the only important brain cells that need to be stimulated by these devices. However, research published in Nature Biomedical Engineering reveals that it may also be important to target the supportive glial cells surrounding the neurons.
Artificial lungs have long been used to help sick children until a lung transplant is available.
While these devices are helpful in supplying oxygen to children suffering from cystic fibrosis, pulmonary hypertension, and pulmonary fibrosis, among other diseases, during the wait for lung transplants, they restrict mobility.
