Abstract: The present invention concerns to a method, a percutaneous access path providing device and a kit of instruments for the treatment of fractured vertebrae, in particular for treating spinal compression fractures in humans. In particular the invention concerns to a percutaneous access path providing device comprising a vertebra access cannula and a vertebra introducer stylet, wherein the vertebra introducer stylet has a tip.

Abstract: A catheter for dialysis for long-term application features a proximal end for introducing into a blood vessel, a distal end for extracting blood and for introducing purified blood, and a fixing member surrounding a tube section for fixing the catheter on the patient. The fixing member has a receiving part and an opening part, wherein, with respect to the receiving part, the opening part can be moved from an opening position, in which the tube section is insertable into the fixing member, into a closing position, in which the tube section is fixed in the fixing member.

Abstract: The invention relates to a height restoring device for restoring the height of and stabilizing the spinal column, in particular for stabilizing broken vertebral bodies or contused intervertebral discs, which device can be arranged in an insertion position in a compression-fractured vertebral body or between adjacent vertebral bodies and once there, can be transferred from the insertion position into an expansion position by means of an expansion apparatus.

Abstract: Catheter system for inserting and positioning a double-lumen catheter in a blood vessel, including a double-lumen catheter having a distal catheter tip, with a first lumen and a second lumen, a first mandrin which extends through the first lumen and a second mandrin which extends through the second lumen, both mandrins of the catheter being radio-opaque. The distal end of the second mandrin is arranged at a distance (X) in the proximal direction from the distal catheter tip, the distance between the distal catheter tip and the distal end of the second mandrin corresponding in particular to a functional catheter tip length.

Abstract: A delivery catheter including a valve body having a closeable valve opening for introducing a medical device in insertion direction into, in particular, a blood vessel, the valve opening, when a medical device is not introduced, tapering in the insertion direction, and a sealing section, which in a closed position at least in sections is subject to a pretension, directly adjoins the taper, so that the sealing section, when a medical device is introduced, is actuated from the closed position into an open position in such manner that the sealing section encloses the medical device in a substantially fluid-tight manner.

Abstract: A system comprising a sluice and a catheter. The catheter including an inner, a middle and an outer tube. A stent is disposed in a distal-end portion of the catheter between the inner and outer-tube. The middle-tube ends distally at the proximal end of the stent. An actuating unit having a drive unit provided in the proximal region of the catheter for releasing the stent. A connecting portion is provided between the drive unit and the sluice. The drive unit is cooperating with the middle-tube and the connecting portion where the drive unit is operated the middle-tube is displaced in the distal direction and the actuating unit together with the outer-tube attached thereto is displaced in the proximal direction. The inner-tube is cooperating with the middle-tube and/or the connecting portion and/or the drive unit in such a way that the inner-tube is displaced at least to some extent relative to the actuating unit.

Abstract: The present invention concerns an assembly for inserting a catheter into a body lumen, the assembly comprising a introduction, an elongate fixing element, wherein with its distal end the fixing element is securable to the introduction device, and wherein at the proximal end of the fixing element a clamping device is provided for securing a guide wire in relation to the introduction device. Further, the assembly comprises a catheter comprising means for releasably engaging the clamping unit, wherein by engagement of the means of the catheter with the clamping unit the guide wire is movable through the introduction device and wherein, upon disengagement of the means of the catheter from the clamping unit, the guide wire is non-movably secured relative to the introduction device.

Abstract: The present invention concerns a double-lumen catheter and a method for delivering or withdrawing fluids to/from a patient, in particular for use in hemodialysis. The double-lumen catheter comprises an elongated tubular body having a proximal end and distal end, with the distal end being positionable within a vessel of a patient, a divider wall extending along an interior of said tubular body and separating said interior into an intake lumen and a return lumen. The intake lumen and said return lumen each comprise an opening sloping toward the divider wall and toward the distal end of the tubular body, respectively, the openings.

Abstract: The present invention relates to a double lumen catheter tube having a substantially circular cross-section and comprising a catheter tube body having a longitudinal axis, and further comprising an outer tubular and an inner divider wall inside the catheter tube body dividing said catheter tube body into a first and a second lumen. The first and the second lumen each comprise a cross section having the shape of an isosceles triangle with three rounded vertices. The tubular wall comprises wall sections that have a smaller wall thickness.
