Novel 3D-Printed Flexible Polymer Esophagus Stent for Esophageal Cancer

Description:

More than 17,000 patients are diagnosed with esophageal cancer each year and it ranks sixth among all cancers in mortality. Many who are diagnosed have an occluded esophagus and utilize a self-expanding metal stent (SEMS) for drinking and feeding.  However, SEMS stents can cause chest pain, restenosis, and can even migrate into the stomach. This technology provides a 3D-printed tubular flexible polylactic acid/thermoplastic urethane (PLA/TPU) stent with upward spiral grooves. This unique design allows for excellent flexibility with the ability to gradually self-expand and revert to its original shape. This design overcomes the complications associated with SEMS with a higher expansion and compression force than SEMS stents. Additionally, the novel 3D-printing method enables a lower cost stent that can be personalized and tailored to the patient.
