Enterra® II System—an Advanced Treatment for Gastroparesis—Receives FDA Approval for MR Conditional Use 

St. Louis Park, MINN.— October 25, 2023—Enterra Medical, Inc., an innovator in treatments for people living with gastroparesis, announced today that the Enterra® II System has been granted MR Conditional approval from the United States Food and Drug Administration (FDA). 

The Enterra II System (specifically its component parts Enterra 37800 Neurostimulator and Enterra Therapy 4351-35 unipolar leads) is an advanced treatment system, designed to relieve the nausea and vomiting symptoms associated with gastroparesis—a complex medical condition that prevents the stomach from emptying properly. 

The MR Conditional label means that patients who receive or have received the Enterra II System in the past can safely undergo Magnetic Resonance Imaging (MRI) examinations of the head or upper/lower extremity under certain conditions. 

“This is a significant milestone in our journey to increase innovation in this therapeutic area and to help people living with gastroparesis find relief,” said Peter Sommerness, Chief Executive Officer of Enterra Medical. 

“For people living with gastroparesis who have considered Enterra Therapy in the past, the ability to have MRI scans may have been an important factor in their decision,” said Kenneth Koch, MD, Vice President and Medical Director of Enterra Medical. “We are hopeful that the ability to perform MRI examinations will bring patients one step closer to relief from their nausea and vomiting symptoms with Enterra Therapy. We remain passionately focused on helping all gastroparesis patients take back their seat at the table.”

Important Safety Information

Intended Use: The Enterra® Therapy  System is an implanted device that provides gastric stimulation to treat chronic, intractable, nausea and vomiting that is not well treated by drugs or other means in patients aged 18 to 70 years caused by diabetes or an unknown origin.

Contraindications: Enterra Therapy is only for patients who are healthy enough for surgical procedures and/or anesthesia. Once implanted, patients need to avoid diathermy, which is deep heat treatment from electromagnetic energy, as it may cause injury or device failure. 

Warnings: Enterra Therapy has not been studied in pregnant women, patients under the age of 18, or over 70. Issues may occur if the system interacts with other implanted devices such as pacemakers. Patient injury or device failure may be caused by other medical treatments such as electrocautery, defibrillation/cardioversion, therapeutic ultrasound, or radiofrequency (RF)/microwave ablation. Patient activities may cause shocking or jolting sensations.
