Device and method for through the scope endoscopic hemostatic clipping

A medical device for causing the hemostasis of a blood vessel for use through an endoscope, said medical device comprising:

• a clip, the clip having at least two clip legs;
• an outer sleeve, the outer sleeve reversibly movable with respect to the clip both to open the at least two clip legs and to close the at least two clip legs;
• a control wire coupled to the outer sleeve for moving the outer sleeve relative to the clip:
• an axially rigid sheath enclosing the control wire, the sheath couplable with, and uncouplable from, the clip;
• a handle coupled to the axially rigid sheath;
• and
• an actuator coupled to the control wire, the control wire engageable by the actuator to move the outer sleeve to open the at least two clip legs, to close the at least two clip legs, and to uncouple the clip from the sheath.

A method of providing and using a medical device to deploy a clip for causing the hemostasis of a blood vessel, said method comprising:

• (i) providing a medical device comprising:
• a clip, wherein the clip has at least two clip legs;
• a control wire coupled to the clip, the control wire reversibly operable both to open the at least two clip legs and to close the at least two clip legs, the control wire being uncouplable from the clip;
• an axially rigid sheath enclosing the control wire, the sheath able to communicate a force opposing a force of the control wire;
• a handle coupled to the axially rigid sheath;
• and
• an actuator coupled to the control wire, the control wire engageable by the actuator to open the at least two clip legs and to close the at least two clip legs and to uncouple the control wire from the clip;
• (ii) advancing the medical device so that the clip is located at the desired deployment location;
• and
• (iii) moving the actuator to close the clip legs, and optionally to reopen and reclose the clip legs, and to uncouple the clip from the control wire.
