Abstract
A medical device for causing the hemostasis of a blood vessel for use through an endoscope comprises: a handle; a sheath device, which is attached to the handle; a clamp device including a clamp housing provided on the distal end of the sheath device and at least two, in particular exactly two clamp arms; a control wire extending through the sheath device and reversibly movable in the distal and proximal direction; an actuator coupled to the proximal end of the control wire and actuable to reversibly move the control wire in the distal and proximal direction; wherein the clamp arms are each coupled to the distal end of the control wire.

A medical device for causing hemostasis of blood vessel comprising:
- a handle;
- a sheath device, which is attached to the handle;
- a clamp device comprising a clamp housing provided on the distal end of the sheath device and at least two, in particular exactly two clamp arms;
- a control wire extending through the sheath device and reversibly moveable in the distal and proximal direction;
- an actuator coupled to the proximal end of the control wire and actuable to reversibly move the control wire in the distal and proximal direction;
- wherein the clamp arms are each coupled to the distal end of the control wire and wherein the clamp device is actuable to open and close the clamp arms by a movement of the control wire such that a movement of the control wire in a proximal direction is translated into a closing movement of the clamp arms and a movement of the control wire in the distal direction is translated into an opening movement of the clamp arms;
- wherein the sheath device comprises a sheath, preferably an extendable coiled sheath, and a connect tube, which defines a longitudinal axis and is fixedly connected to the distal end of the sheath;
- where the clamp housing is directly and releasably connected to the connect tube in such a way that the clamp housing can be rotated relative to the connect tube about the longitudinal axis.
