Endoscopic apparatus having a clip device

An endoscope having a hemostatic clip device for hemostasis, the endoscope comprising:

• an insertion tube extending to a distal tip comprising an elevator with a slot formed therethrough;
• a delivery apparatus disposed through the insertion tube and cooperable with the elevator, the delivery apparatus comprising an operating wire, an outer sheath and a handle, the operating wire being cooperable with the elevator of the distal tip of the endoscope and slidably disposed within the outer sheath;
• and
• a hemostatic clip cooperable with the delivery apparatus, the clip comprising a first retainer, a plurality of arms extending distally from the first retainer, and a sliding ring disposed about the plurality of arms, the arms being formed of a resilient material and shaped so that the arms tend to be spaced apart from each other,
• wherein the sliding ring is connected to the operating wire, and
• wherein the sliding ring is exposed to the slot of the elevator when the outer sheath is pulled and the sliding ring engages the elevator when the operating wire is retracted such that the elevator pivots toward the hemostatic clip and moves the sliding ring toward the arms to close the arms together.

A method of treating a target in a patient, the method comprising:

• providing a hemostatic clip delivery system cooperable with an endoscope having an elevator with a slot formed thereon, the system comprising:
• a delivery apparatus comprising an operating wire, an outer sheath and a handle, the operating wire being cooperable with the elevator of the endoscope and slidably disposed within the outer sheath;
• and
• a hemostatic clip cooperable with the delivery apparatus, the clip comprising a first retainer, a plurality of arms extending distally from the first retainer, and a sliding ring disposed about the plurality of arms, the arms being formed of a resilient material and shaped so that the arms tend to be spaced apart from each other, wherein the sliding ring is connected to the operating wire;
• introducing the outer sheath through the endoscope to the target;
• moving the outer sheath until the sliding ring is positioned next to the elevator;
• retracting the outer sheath to expose the sliding ring and the clip to the slot of the elevator to extend the arms to an open position;
• slidably disposing the operating wire within the slot of the elevator;
• retracting the operating wire to engage the elevator with the sliding ring;
• and
• moving the elevator outwardly so that the sliding ring slides over the arms causing the arms to close on the target.
