Patent ID: 8211124

Claim:
A surgical clip comprising an elongated member and a pair of biasing mechanisms coupled to said elongated member, said elongated member comprising shape memory material and having a memory set closed configuration from which it is moveable to a plurality of open configurations, said biasing mechanisms being selectively adjustable to bias the clip toward any of said plurality of open configurations, each biasing mechanism comprising a biasing member and an actuator member, each biasing member adapted to apply a biasing force to said elongated member to urge said elongated member away from said closed configuration, and each actuator member being coupled to one of said biasing members and adapted to activate said biasing member to apply said biasing force to said elongated member, wherein a spacing between said actuator members along a length of said elongated member in said closed configuration is less than said spacing in said plurality of open configurations; wherein each biasing member comprises a coil surrounding a portion of said elongated member and each actuator member comprises a sliding member slidably mounted to said elongated member to slidably engage a corresponding one of said coils; wherein said sliding members of said pair of biasing mechanisms are biased to move toward each other; and further wherein said sliding members of said pair of biasing mechanisms are configured to directly contact one another in said closed configuration.
