摘要：
1. A medical device comprising: a catheter with a proximal and distal ends； a hollow bit having a passage inside the bit, having a proximal and distal end, with a tip at the distal end, the proximal end of the bit being the proximal distal end of the catheter； an elongated element axially movable along the longitudinal axis of the catheter and bit, in which the tip is movable by selective axial movement of the elongated element, between the first position in which the tip is proximal to the axis and the second position in which the tip is spaced from the first position. . The medical device according to claim 1, wherein the tip has at least two sections, at least one of which is movable by selective axial movement of the elongated element. The medical device according to claim 2, wherein when the elongated element is removed from the bit passage, a sharp tip is formed. The medical device according to claim 1, wherein in order to drive the bit between the sharp tip and the blunt tip, the elongated element can be retracted and extended from the distal end of the bit. The medical device according to claim 1, wherein when pushing and pushing the elongated element from the distal end of the bit, the tip opens, in general, with the possibility of adapting to the outer diameter of the conductor. The medical device according to claim 1, wherein when pushing the elongated element from the distal end of the bit, the catheter and bit, together include a support catheter. The medical device according to claim 1, in which the bit contains1.
