Duodenal Stent Minimizes Small Intestine Cancer Symptoms

The Evolution Duodenal controlled-release stent expands palliative care options for patients experiencing issues associated with malignant gastric outlet obstruction (GOO), a late stage complication of a variety of GI related cancers such as pancreatic, gastric, duodenal, and cholangiocarcinoma. The stent offers these patients a minimally invasive alternative to relieve symptoms and potentially life-threatening complications resulting from duodenal obstruction, such as abdominal pain, vomiting, malnutrition, and aspiration. The new stent allows for more precise placement and conforms to the patient’s duodenum to reduce the risk of migration, thanks to 18 crowns placed at both the distal and proximal ends, which allow the stent to adapt to the natural curvature of the anatomy.

The proximal and distal flanges are designed to reduce the risk of stent migration, while the patented Flexor catheter with kink-resistant technology provides tracking ability and maneuverability for deployment in the difficult anatomy of the duodenum. Controlled release and recapturing abilities are designed to provide physicians with precise control and maneuverability, ensuring proper placement and potentially reducing complications such as migration and perforation. The Evolution Duodenal stent is a product of Cook Medical (Bloomington, IN, USA) and has been approved by the US Food and Drug Administration (FDA).

“We’re excited to be expanding our line of Evolution stents by bringing to the US market a stent platform that aids physicians and has been available globally for several years,” said Barry Slowey, global business unit leader for Cook Medical’s Endoscopy division. “This stent has been used to treat thousands of patients around the globe, potentially improving quality of life for these patients, and hopefully minimizing the painful symptoms associated with this disease.”

“The Evolution duodenal stent includes several product features that are designed to make stent placement easier and more precise for the physician,” said Prof. John Lee, MD, of the University of California Irvine (UCI) Medical Center (USA). “These features of the stent allow for better wall apposition and potentially reduce the risk of migration, both of which are essential when treating patients with gastric outlet obstructions.”
