Abstract
A surgical fastener comprising a clip movable between an open configuration and a closed configuration and a biasing member contacting the clip and biasing the clip to its open configuration when the biasing member is actuated. The biasing member and clip both tend to assume the closed configuration when no external forces are applied to them. A needle may be releasably attached to the clip. Methods for making the fasteners are also disclosed, in which both the clip and the biasing member are set in the closed position.
Claims52
A surgical fastener, comprising a clip movable between an open configuration and a closed configuration, and a biasing member contacting said clip, said biasing member biased to conform to said closed configuration when in a free state, further comprising two restraints on said clip, said biasing member extending between said two restraints in said closed configuration, further comprising a release mechanism coupled to said clip and adapted to engage said clip at at least one of said restraints and to bias said biasing member to force said clip into said open configuration.
A surgical fastener, comprising a clip movable between an open configuration and a closed configuration and having a shape memory set to said closed configuration, and a biasing member contacting said clip and having a shape memory set to conform to said closed configuration, further comprising a locking mechanism engaged between said clip and said biasing member for biasing said clip and said biasing member to said open configuration.
A surgical fastener comprising a clip movable between an open configuration and a closed configuration, and a coil surrounding at least a portion of said clip and movable between said open configuration and said closed configuration, each of said clip and said coil being adapted to assume said closed configuration when in a free state, wherein said coil is adapted to exert an opening force against said clip when said coil is axially compressed.
A surgical fastener for connecting at least two structures, said surgical fastener comprising:
- a clip adapted to connect said at least two structures together and comprising shape memory material, said clip having an open configuration and a memory set closed configuration;
- and
- a coil surrounding at least a portion of said clip, said coil comprising shape memory material and having an open configuration and a memory set closed configuration, said coil urging said clip toward its open configuration when axially compressed and tending to urge said clip toward its closed configuration when returning to its memory set closed configuration.
