MassDevice is reporting that Pluromed out of Woburn, MA won FDA approval for the firm’s BackStop gel for lithotripsy procedures. Designed to be injected into the ureter next to the stone, the gel immediately stiffens to prevent the stone residue from moving around.
BackStop™ is a water soluble gel that is delivered above the stone in the ureter and acts to prevent retrograde stone migration during ureteroscopic lithotripsy. Once delivered, the catheter is removed, thus freeing the operating field. BackStop™ is completely atraumatic and will conform to any shape ureter. It has no mechanical parts and will not interfere with the lithotripter. BackStop™ is compatible with all forms of ureteroscopic lithotripsy, including laser and mechanical lithotripters.
When lithotripsy is complete, BackStop™ is dissolved via conventional irrigation and the ureteral occlusion is reversed.
