Medical Device for Causing Hemostasis of Blood Vessel

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 defining a longitudinal direction with a clamp base in particular in the form of a sleeve provided on the distal end of the sheath device and at least two, in particular exactly two clamp arms, said clamp housing defining an interior space;
• a control wire extending through the sheath device and reversibly movable in the distal and proximal direction;
• and
• 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 clamp arms are coupled to the distal end of the control wire via a pivot pin extending through corresponding through-holes provided in the proximal end sections of the clamp arms and being held releasably at the distal end of the control wire,
• where the pivot pin protrudes laterally on both sides from the clamp arms and the distal end of the control wire and
• two locking noses are provided on the clamp housing extending into the interior space of the clamp housing, wherein the locking noses are designed in such a way that they allow the pivot pin to pass them in the proximal direction but prevent passing of the pivot pin in the distal direction in order to lock the clamp arms in a closed state.
