Device and Method for Through the Scope Endoscopic Hemostatic Clipping

A medical device, comprising:

• a clip having first and second clip legs;
• a control wire being operable both to open the clip legs and to close the clip legs;
• a sheath enclosing the control wire;
• a link coupling the control wire to the clip, the link being movable from a coupled configuration in which the clip is coupled to a distal end of the control wire to a released configuration in which first and second arms of the link are configured to move radially outward at an area of the sheath to release the control wire from the clip;
• and
• an actuator coupled to the control wire, the control wire engageable by the actuator to move the control wire to open and close the clip legs and to move the link from the coupled configuration to the released configuration.

A medical device, comprising:

• a clip having first and second clip legs;
• a control wire coupled to the clip, the control wire being movable relative to a sheath to open and close the clip legs, a distal end of the control wire received between arms of the clip;
• the sheath enclosing a distal portion of the control wire, wherein the control wire is configured to release from the clip as the arms spread laterally away from the control wire;
• and
• an actuator coupled to the control wire to move the control wire relative to the sheath and to release the control wire from the clip.

A method, comprising:

• inserting a medical device comprising a clip having first and second clip legs, a control wire, a sheath enclosing the control wire and a proximal portion of the clip;
• positioning the medical device at a desired deployment location;
• moving the control wire distally relative to the sheath to deploy the first and second clip legs distally from the sheath ;
• adjusting a position of the clip so that target tissue is received between the first and second clip legs;
• drawing the control wire proximally relative to the sheath to draw the clip into the sheath to receive the target tissue between the first and second clip legs;
• applying a tensile force of at least a threshold level to the control wire to separate a separable link coupling the control wire to the clip.
