Through the scope tension member release clip
First Claim
1. Apparatus for deployment of a hemostatic clip comprising:
- a handle assembly;
a shaft connected to a distal portion of the handle assembly;
a clip assembly releasably coupled to a distal portion of the shaft, the clip assembly including clip arms and a capsule cooperating with the clip arms to provide a first user feedback indicating a decision configuration of the clip assembly; and
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.

Abstract
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.

19. 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 wire 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;
a capsule releasably connected to the bushing;
clip arms slidable within the capsule between a distal open configuration and a proximal closed configuration;
a tension member slidable with the clip arms, the tension member biasing the clip arms toward the open configuration; and
a yoke slidable within the capsule, 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 wire, wherein distal movement of the control wire slides the clip arms into the open configuration, and proximal movement of the control wire slides the clip arms into the closed configuration. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 35, 36)

28. A method for hemostatic clipping comprising:
-
inserting a shaft of a clipping device through a working lumen of an endoscope, wherein the shaft extends to a distal clipping assembly of the clipping device including a plurality of clip arms and wherein a control wire extends through the shaft from the clipping assembly to a handle coupled to a proximal end of the shaft;
manipulating the handle assembly to move a control wire within the shaft to move the clip arms between an open and a closed configuration;
generating a first user feedback indicating a decision configuration of the apparatus; and
generating a second user feedback indicating separation of the clipping assembly from the shaft. - View Dependent Claims (29, 30, 31, 32, 33, 34)
