Through the scope tension member release clip

摘要

An apparatus for deployment of a hemostatic clip comprises a handle assembly, a shaft connected to a distal portion thereof and a clip assembly releasably coupled to a distal portion of the shaft. The clip assembly includes clip arms and a capsule cooperating with the clip arms to provide a first user feedback indicating a decision configuration of the clip assembly. In addition, the apparatus includes a control wire including a ball connector, the control wire extending from the handle assembly and coupled to the clip assembly by the ball connector to maintain the clip assembly coupled to the shaft, wherein the ball connector is detachable from the clip assembly to provide a second user feedback indicating separation of the clip assembly from the shaft.

1. A method, comprising:
advancing to a target site within a living body a medical device comprising a clip having first and second arms biased toward an open configuration, the device further comprising a control wire removably connected to the clip and an elongated sheath housing the control wire; actuating an actuator to move the control wire proximally and distally to open and closed the first and second clip arms to grasp tissue therebetween; generating a first user feedback during proximal movement of the control wire; and applying a first force to the control wire to sever a connector between the control wire and the clip, uncoupling the connector from the clip at a preselected failure point to provide a second user feedback indicating separation of the clip from connector.
