A medical device includes a guide unit having a guide tube with a longitudinal axis, a proximal first coupling part fixedly connected to the guide tube, and a distal pivoting head with a cylindrical surface. An actuating tube is axially movable in the guide tube and is connected to the pivoting head. The actuating tube causes a pivoting movement of the pivoting head via a proximal operating element. In the device, in order to orient a distal guide element for a rotatable surgical tool more precisely and thus angularly orient the working head of such a tool, the operating element is pivotable about the longitudinal axis and causes the pivoting movement of the pivoting head by the axial displacement of the actuating tube.

Medical device

A device () for fixating a rod () on a bone with a tulip, with a pedicle screw () and with a tightening screw (). The rod clamp () is pivotable to the tightening screw and can follow transverse motions of the rod (). This increases the stability of the entire structure, particularly in the application in spine surgery.

The present invention relates to a stent delivery system comprising a catheter tube defining for a self-expanding stent a bed having a length direction in line with the catheter length, a radially outward facing stent-receiving surface, a distal end at or near the distal end of the catheter and a proximal end spaced proximally from the distal end; an outer catheter tube to circumferentially surround the bed; and the outer tube being arranged to be withdrawn proximally to release the self-expanding stent radially outwardly from the bed; and further comprising: on the stent receiving bed surface, immediately distal of the proximal end of the bed, a first pinch zone; on the outer tube, at or near a distal end thereof, and on its radially inwardly facing surface, a second pinch zone; the first and second pinch zones facing each other when the distal end of the outer tube is not quite fully withdrawn proximally, relative to the bed; the facing of the opposed first and second pinch zones defining a reduced-width annulus for pinching the proximal end of the stent to make available increased resistance to relative axial movement between the stent and the catheter shaft just prior to full withdrawal of the outer tube.
