It was reported that the procedure was to treat a superior mesenteric artery.The vessel was pre-dilated with an unspecified balloon.The 7.0x18mm herculink elite balloon expandable stent was advanced and deployed at nominal pressure.The stent was deployed successfully.The delivery system was pulled back to the ostium of the vessel and into the aorta, re-inflated to 15 atmospheres to assure proximal apposition to the vessel, but the balloon ruptured.The stent delivery system was attempted to be removed and resistance was met as part of the balloon became caught with the edge of the stent.A piece of the ruptured balloon separated from the device; however, a snare device was used to retrieve the separation portion successfully.There was no adverse patient sequela and no clinically significant delay.No additional information was provided.
