Through the scope tension member release clip
First Claim
1. A clip deployment apparatus insertable to locations within a body through an endoscope, the apparatus comprising:
- an elongated member extending from a proximal end to a distal end;
a control element extending from the proximal end of the elongated member to the distal end thereof;
a bushing coupled to the distal end of the elongated member, the busing including a plurality of tabs extending radially inward from a distal end thereof;
a capsule releasably connected to a distal end of the bushing by a plurality of substantially A-shaped openings formed in a proximal end thereof, each of the A-shaped openings receiving a corresponding one of the tabs;
a clip slidably received within the capsule, the clip including clip arms moveable between open and closed configurations;
a tension member slidably received within the capsule and coupled to the clip; and
a yoke slidably received within the capsule and removably coupled to the tension member, a first end of the yoke being releasably connected to the tension member and a second end of the yoke being connected to the control element so that distal movement of the control element draws the yoke, the tension member and the clip distally to a position in which the clip arms are in the open configuration and proximal movement of the control element pushes the yoke, the tension member and the clip proximally to a position in which the clip arms are in the closed configuration.

Abstract
A hemostatic clip assembly for mounting on a delivery device comprises a capsule and a clip slidably mounted within the capsule so that, when the clip is drawn proximally into the capsule, arms of the clip are drawn together to a closed position, an abutting surface of at least one of the arms contacting a corresponding surface of the capsule when the clip is drawn to a predetermined position within the capsule to provide a first user feedback indicating closure of the clip in combination with a tension member connected to the clip arms and biasing the clip arms toward an open, tissue receiving configuration and a yoke slidably received within the capsule and releasably coupled to the tension member, the yoke including a ball cavity for receiving a ball connector of a control element of the delivery device to maintain the clip assembly coupled to the delivery device, wherein the control element is frangible to detach the yoke from the delivery device and to provide a second user feedback and, wherein release of the yoke from the tension member provides a third user feedback.
