A device for retrieval of a foreign body, such as an undeployed stent from a vessel of a patient, has a central shaft for receiving a guidewire therein. A balloon support extends from the central shaft and has a free end carrying an inflatable balloon. The inflatable balloon is arranged to expand inwardly towards the central shaft on inflation, so as in use to bear against the outer circumference of the stent and hold the stent against the central shaft. The combined stent and device can then be withdrawn from the vessel.
