Abstract: A device for locating and retrieving a misplaced foreign body that has metallic characteristics includes a shaft connected to a handle and a retrieval tool that is coupled to the shaft and moves between a deployed position and collapsed position. The tool has a magnetic element that generates a magnetic field, wherein the magnetic field extends over a greater area in the deployed position and is of sufficient strength to attract the foreign body such that it is held in contact with the tool. The device can be part of an automated robotic system and can also include a metal detector to assist in locating the misplaced foreign body.

Abstract: A device for closing an opening formed in a patient's body without the use of sutures. The device includes a patch formed of a flexible that can be positioned between an open position and an at least partially closed position. The body has a plurality of sharp protrusions formed along the first face for securely attaching the flexible body to a target structure within the patient's body in which the opening is formed such that the flexible body extends across and closes the opening. The device further includes an instrument for delivering the patch to an inner face of a structure in which the opening is formed. The instrument has a first member that mates with the patch for securely, yet releasably, attaching the patch to the instrument to allow delivery of the patch.
