Closure device and methods for making and using them

A device for engaging tissue, comprising:na generally annular-shaped body defining a generally central opening and a plane, the body having a plurality of outer curved regions, the body movable from a planar configuration with the body lying substantially in the plane to a transverse configuration having at least a portion of the body extending out of the plane;a plurality of tines extending from the body into the central opening, a portion of pairs of adjacent outer curved regions of the plurality of outer curved regions extending towards the central opening to terminate at each tine of the plurality of tines; andat least one spring element extending between pairs of adjacent tines of the plurality of tines, each at least one spring element aiding in expanding the body as the body moves from the planar configuration to the transverse configuration, wherein each of the at least one spring element has a curved inner region that curves towards the central axis.

A device for engaging tissue, comprising:na generally annular-shaped body disposed about a central opening and a central axis normal to the plane, the body having a plurality of outer curved regions with adjacent outer curved regions of the plurality of outer curved regions being joined together to define an outer periphery of the body, the body defining a plane and being movable from a planar configuration with the body lying substantially in the plane to a transverse configuration having at least a portion of the body extending out of the plane;a plurality of tines extending from the body into the central opening, each tine of the plurality of tines extending from a junction of a pair of adjacent outer curved regions of the plurality of outer curved regions that extend toward the central opening; andat least one spring element extending between pairs of adjacent tines of the plurality of tines, each of the at least one spring elements having a spring curved inner region that curves towards the central axis and a spring curved outer region that curves towards an apex of one of the plurality of outer curved regions, the at least one spring element aiding in drawing the tissue towards the central axis of the body when the body moves from the transverse configuration towards the planar configuration.
