Abstract:
1. A surgical device having a sheath with an interior passage and legs slidably received within the passage of the sheath, the legs being adapted to move outwardly away from each other in a radially outward direction when deployed from the sheath to establish a deployed position, and to move inwardly toward each other in a radially inward direction to collapse within the sheath and define a stowed position, each of the legs having a transverse cross-sectional shape defined by a transverse cross-section through the leg and through a radially-inward first surface thereof that is concave, an oppositely-disposed radially-outward second surface thereof that is convex, and two oppositely-disposed lateral sides thereof interconnecting the first and second surfaces, each of the lateral sides defining with the first and second surfaces a rounded radially-inward first edge and a rounded radially-outward second edge, respectively, the lateral sides of adjacent pairs of the legs having portions that do not contact each other when the legs are in the deployed position, the legs and sheath being configured to cause the legs to fully collapse within the sheath such that the portions of the lateral sides of adjacent pairs of the legs contact each other at only the second edges of the legs when the legs are in the stowed Position within the sheath to thereby define a tubular shape comprising a circumferentially continuous enclosure surrounding an opening.
