Temple Testing Miniature Lung Coils to Treat Emphysema
January 31, 2013  | 

Philadelphia, PA - Temple researchers are testing whether implanting miniature coils in the airways of diseased lungs can improve breathing, activity levels and quality of life for emphysema patients.

The coils work by compressing damaged tissue, which allows the healthier parts of the lung to function more efficiently and make breathing easier. The coils are made of Nitinol, a metal commonly used in medical implants, and offer a minimally invasive alternative to lung volume reduction surgery.

Temple is testing the RePneu® Lung Volume Reduction Coils as part of the Lung Volume Reduction Coil Treatment in Patients with Emphysema (RENEW) Study, which is being conducted by California-based PneumRx, the company that makes the coils. European studies have shown that patients treated with the coils have an improved quality of life, better ability to exercise and reduced breathlessness.

"The RePneu coils are delivered through a bronchoscope in a short, non-surgical procedure that is performed under conscious sedation or general anesthesia," says Gerard Criner, MD, Chair of the Department of Medicine at Temple University School of Medicine and lead investigator of the trial at Temple. "A typical procedure takes approximately 30 minutes and involves the implantation of about 10 coils."

"Our involvement in the RENEW study means that we can give emphysema patients an option that most hospitals don't offer," continues Dr. Criner, who is also Director of the nationally ranked Temple Lung Center, one of the nation's leaders in the diagnosis, treatment and research of patients with complex lung problems.

The RePneu coils are pre-formed into a coil shape, but they are delivered to the lung in a straight configuration. When the coils are deployed into the lung, they recover to their original shape, gathering and compressing diseased tissue and allowing the healthy tissue to function better. The coils are a permanent implant. Continue>
