Device and method for through the scope endoscopic hemostatic clipping
DC CAFCFirst Claim
Patent Images
1. A medical device, comprising:
- a clip having a first clip leg having a first inner surface and a second clip leg having a second inner surface;
a control member extending from a proximal actuator to the clip; and
a linkage operably associated with the control member to spread the first and second clip legs apart from one another into a tissue-receiving configuration as the control member is moved distally relative to the clip, the linkage contacting the inner surfaces of the first and second clip legs to drive the first and second clip legs radially outward as the control member is moved distally relative to the clip.

Abstract
Medical device used to cause hemostasis of blood vessels using a clip arrangement delivered to a target region through an endoscope. Method for using the device to cause hemostasis of a blood vessel through an endoscope. Medical device including a reversibly closeable clip, a locking arrangement, a control wire, a sheath, and a handle with an actuating trigger. Through the endoscope, hemostatic clipping device that is fully reversible and lockable. Hemostatic clip that reversibly targets and clips bleeding ulcers.

13. A medical device, comprising:
-
a clip having a first clip leg having a first inner surface and a second clip leg having a second inner surface; a sleeve housing a portion of the clip therein, the clip being axially movable relative to the sleeve by a control member extending from a proximal actuator to the clip; and a linkage operably associated with the control member to move the clip distally out of the sleeve and cause the first and second clip legs to spread apart from one another into a tissue-receiving configuration as the clip is moved distally relative to the sleeve, the linkage contacting the inner surfaces of the first and second clip legs to drive the first and second clip legs radially outward as the control member is moved distally relative to the clip. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method, comprising:
-
inserting into a body a medical device comprising a clip having a first clip leg having a first inner surface and a second clip leg having a second inner surface, a control member extending from a proximal actuator to the clip and a linkage coupled to the control member; positioning the medical device at a desired deployment location; moving the control member distally to cause the clip to move distally relative to a sleeve housing at least a portion of the clip therein, the movement causing the linkage to contact the first and second inner surfaces to drive the first and second clip legs radially outward to a tissue-receiving configuration; adjusting a position of the clip so that target tissue is received between the first and second clip legs; drawing the control member proximally relative to the sleeve to draw the clip into the sleeve to receive the target tissue between the first and second clip legs; and applying a proximal tensile force of at least a threshold level to the control member to separate a link coupling the control member to the clip.
