1. A tissue clip, comprising:
a grasper having a first end and a second end, the grasper including a spring portion at the second end, and jaws at the first end biased toward each other by the spring portion into a closed configuration to grasp tissue;
an actuator mounted with respect to the grasper; and
a loop coupled to the actuator;
wherein the actuator is movable upon movement of a separately formed instrument releasably coupled to the loop to move the actuator relative to the spring portion and the jaws to cause the spring portion to move the jaws from the closed configuration to an open configuration.
 
5. A tissue, further comprising:
a grasper having a first end and a second end, the grasper including jaws at the first end biased toward each other into a closed configuration to grasp tissue;
an actuator mounted with respect to the grasper;
a loop coupled to the actuator; and
a filament extending away from the clip to a distal end of the filament forming the loop;
wherein the actuator is movable upon movement of a separately formed instrument releasably coupled to the loop to move the actuator relative to the jaws to cause the jaws to move from the closed configuration to an open configuration.
 
13. A tissue clip system comprising:
an elongate tether member having a first end and a second end;
a first tissue clip coupled to the first end of the elongate tether member, the first tissue clip comprising a first grasper having a first end and a second end, first jaws at the first end of the first grasper which are biased toward each other, and a first actuator mounted with respect to the first jaws, wherein relative movement of the first actuator with respect to the first jaws causes the first jaws to move from a closed configuration to an open configuration;
a second tissue clip coupled to the second end of the elongate tether member, the second tissue clip comprising a second grasper having a first end and a second end, second jaws at the first end of the second grasper which are biased toward each other, and a second actuator mounted with respect to the second jaws, wherein relative movement of the second actuator with respect to the second jaws causes the second jaws to move from a closed configuration to an open configuration; and
a deployment catheter having an engagement end slidably disposed within a lumen of an instrument sheath and configured to engage at least one of the actuators.
