Self-closing surgical clip for tissue
First Claim
1. Apparatus for fastening tissue comprising a fastener having a stopper, where said stopper includes one or more distal members, and a plurality of proximal members flexibly attached to said stopper, where said fastener has a fastened configuration in which said plurality of proximal members oppose at least a portion of said stopper, and an open configuration where said fastener is openly restrained from said fastened configuration to accept tissue, such that tissue positioned within said open configuration is compressed when said fastener is unrestrained, wherein at least one of said plurality of proximal members of said fastened configuration has a distally oriented end, and wherein said distally oriented end of said fastened configuration opposes at least a portion of said stopper, further including a piercing member having a tip and a hollow end for accepting at least a portion of said plurality of proximal members.

Abstract
A self-closing fastener is described that comprises a clip passable through a tissue opening. The fastener is adapted for holding by a mechanism in an open configuration for passing through the tissue, followed by releasing the fastener from the holding mechanism, allowing the clip to remain in the tissue in a shape that can clip two or more locations on the tissue. The fastener and delivery devices are particularly useful for tissue approximation, such as anastomosis. When used for anastomosis, the inventive clips provide intima-to-intima contact with a minimal amount of intraluminal exposure.

3. Apparatus for fastening tissue comprising:
-
a fastener having a stopper, where said stopper includes one or more distal members, and a plurality of proximal members flexibly attached to said stopper, said fastener having a fastened configuration where at least one of said plurality of proximal members opposes at least a portion of said stopper; and
a restraint mechanism to releasably restrain said plurality of proximal members of said fastener in an open configuration away from said fastened configuration without restraining said one or more distal members, such that tissue is placeable within said releasably restrained fastener, and where that upon releasing said fastener from said restraint mechanism, said plurality of proximal members return toward said fastened configuration to compress said tissue, further including a piercing member having a tip and a hollow end for accepting at least a portion of said plurality of proximal members. - View Dependent Claims (4)

69. A method for fastening a first tissue and a second tissue with a fastener delivered to said first and second tissues in a holder, said method comprising:
-
piercing the first tissue;
piercing the second tissue;
passing said holder through said piercings of said first and second tissues, where said fastener is releasably coupled to said holder, where said fastener has a stopper and a plurality of terminator arms, where said fastener has a coupled configuration releasably restraining said at least two terminator arms in said holder with said stopper extending approximately perpendicular from said holder, and where said fastener has a decoupled configuration where said plurality of terminator arms and said stopper are opposable across said first and second tissues;
