Abstract
An expandable sheath accommodates a medical device that is being removed from a body with a larger diameter than the sheath. The same sheath may be used to reposition a device, such as an implant for repairing a patent foramen ovale (PFO), within the body to an alternative delivery site. The sheath has one or more perforations on its distal end that permit the distal end portion to expand radially. The sheath may be used to deliver a medical device, surgical instrument, or biological sample.
