摘要： The invention relates to a stent having a tubular grate structure, comprising grate elements, particularly webs (10), and cells (11) delimited by the grate elements, wherein the grate structure can be transferred into a compressed state having a relatively smaller cross-sectional diameter, and into an expanded state having a relatively larger cross-sectional diameter. The invention is characterized in that flexible contact elements (12) are associated with the grate elements, said contact elements being adjusted for transferring radial forces onto a vessel wall (20) and extending on the outer circumference of the grate structure substantially in the longitudinal direction of the respectively associated grate elements, wherein the contact elements (12) are wider than the respectively associated grate elements, at least in sections.

摘要： A damping and shock absorbing method and apparatus for permanent or non-permanent use in the human body consists out of a shape memory alloy material which is cycled through the stress-strain hysteresis to dissipate energy for an effective damping. A sufficiently high pre-stress is applied to the damping element(s) to ensure that the damping working range is within the superelastic cycle. The damping apparatus can be designed to work in tension or compression or - by combination of compression and tension elements - both in tension and compression. Moreover, damping elements from a shape memory alloy can be designed to work also in flexion and extension as well in rotation. The damping apparatus can be designed to have a stroke and force suitable for use in the human body by the design, the structure and the chemical composition of the shape memory alloy and their pre-set properties, such as plateau stresses of the superelastic cycle depend on the ambient temperature, the force of damping elements can also be changed in-situ by changing the temperature of the damping elements. The damping elements out of a shape memory alloy can be combined with elastic elements out of other materials to achieve stress- strain behaviour more suitable for use in the individual human body.

摘要： The invention relates to a medical device for removing concretions (60) from hollow organs of the body, with a functional element (10), which has a rotationally symmetrical lattice structure (20) and a means for holding a concretion in the lattice structure (20), and with a catheter (50) for introducing the functional element (10) into the body and for removing it therefrom, wherein the functional element (10) can be converted from a compressed state in the catheter (50) to an expanded state outside the catheter (50), in which expanded state the functional element (10) is arranged distally from the catheter (50). The invention is characterized in that the lattice structure (20) has a cutting area (21) with webs (22), which are adapted in such a way that they at least partially pass radially through the concretion (60) when the functional element (10) is converted from the compressed state to the expanded state, and the holding means comprises at least one holding element (30), which is connected on the one hand to the lattice structure (20) and on the other hand to a guide wire (40) arranged in the catheter (50), in such a way that the holding element (30) is deflected radially inwards in the expanded state of the functional element (10).
