Stent-X:

Ureteral stents are often utilized in children after surgery to repair an obstruction between the ureter and the kidney. To avoid the inadvertent premature removal of the stent, the dangler string on the stent is removed, and the stent must be removed via a procedure called cystoscopy, which requires children to receive additional general anesthesia and a trip to the operating room. The Stent-X device simplifies the stent removal by utilizing a small magnetic bead and a precisely designed magnet to gently slide the stent out of a child’s body. If the device is proven effective, this new innovation could avoid the risks associated with early overexposure of children to general anesthesia. Stent-X received an NIH SBIR Phase I award to support early stage development and testing that is currently underway.
