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.
Claims15
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;
- a breakable link adapted to couple a control wire to the clip and adapted to be broken by a first predetermined tensile force applied by the control wire;
- the control wire reversibly operable both to open the at least two clip legs and to close the at least two clip legs when the control wire is coupled to the clip;
- an axially rigid sheath enclosing the control wire, the sheath able to communicate a first force opposing a second 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, to close the at least two clip legs, and to uncouple the control wire from the clip;
- wherein when the breakable link is broken, the control wire uncouples from the clip.
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;
- 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;
- and
- a breakable link adapted to be broken by a predetermined tensile force applied by the control wire,
- wherein when the breakable link is broken, the control wire uncouples from the clip.
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;
- wherein the control wire is adapted to be coupled to the clip by a breakable link;
- wherein the breakable link is adapted to be broken by a first predetermined tensile force applied by the control wire;
- and
- wherein when the breakable link is broken, the control wire uncouples from the clip.
