Abstract
Official abstract text for this publication.
The present invention provides a device for delivering and/or recovering an object, such as a patent foramen ovale (PFO) occluder. According to one embodiment of the invention, a device contains an outer sleeve and an inner sheath. The inner sheath has a proximal portion and a distal portion; the distal portion of the inner sheath is disposed inside the lumen of the outer sleeve. The distal portion of the inner sheath can expand radially to facilitate retrieval of an object. The distal portion of the inner sheath has a larger diametrical configuration than the proximal portion of the inner sheath. The distal portion of the inner sheath may be in the shape of a cone or similar shape. The distal portion of the inner sheath further includes slits that form flaps which collapse inward and overlap each other as the distal portion is in its unexpanded configuration.
