摘要： A multilayered catheter tube element (10), preferably for situating a guide wire, comprising a first layer (11) forming the external layer and a second layer (12) at least partially forming the internal layer. The first layer (11) contains at least one plastic or multiple plastics from the group consisting of PEBA, polyamide, and elastomer-modified polyamide and the second layer (12) contains ethylene tetrafluoroethylene. A cost-effective method for producing a multilayered catheter tube element of this type is also disclosed.

摘要： The invention relates to a method for the production of at least one longitudinal section of a catheter, wherein the method comprises the winding of film, and the film is provided in the form of strips, the film strip is wound in the manner of a screw such that the side edges of the film strip extending in the manner of a thread overlap the film strip, and further a bonded connection is created in the overlapping region such that the longitudinal section has a closed and at least fluid-tight surface. The invention further relates to a catheter produced according to the method, and a device for carrying out the method.

摘要： A device to produce strand-shaped products from thermoplastic or elastomer materials comprising a paste extruder having a specially implemented internal volume defined by a cylindrical internal mandrel (2) and an external cylinder mantle (1). The polymer material is charged in the internal volume. The polymer raw material may be provided as a powder or granulate or as material cores produced in a separate precursor process using the same device. The polymer mass is melted by heating and discharged using an expulsion piston (3). A static mixing line (5) is provided in the outlet area, in which penetration of the melt flow occurs due to special shaping and uniform mixing of the molten material. A homogeneous material flow is achieved, which is supplied via a melt duct to a conventional longitudinal or transverse extrusion head (4).

摘要： In a process for the irradiation of strand-shaped irradiated material (19; 19a-e), in particular cable insulation or sheathing (31) capable of being cross-linked by irradiation, or tubes, hoses, or profile elements capable of being cross-linked by irradiation, with electron beams impinging transversely to the longitudinal axis of the irradiated material (19; 19a-e), which strike the irradiated material (19; 19a-e) from two fixed irradiation directions (R1, R2), located at an angle to one another which is other than zero and for preference is a right angle, a uniform irradiation is achieved in a simple manner in that a scanned electron beam (17) is created from an electron beam (11) in a scanner (12) by means of a scan device (13), which by means of a temporally-actuated back-and-forth slewing movement in a prescribed angle range creates a radiation fan transversely to the longitudinal direction of the irradiated material, and that the scanned electron beam (17) is deflected by a deflection magnet (16, 16′) arranged between the scan device (13) and the irradiated material (19; 19a-e) in such a way for each scan angle of the irradiation field that it impinges on the irradiation material (19; 19a-e) to be treated from one of the two fixed irradiation directions (R1, R2).
摘要翻译：在用于照射线状辐射材料（19; 19a-e）的过程中，特别是能够通过照射交联的电缆绝缘或护套（31）或能够交叉的管，软管或型材元件与照射材料（19; 19a-e）的纵向轴线相撞的电子束从两个固定的照射方向（R1，R2）撞击照射的材料（19; 19a-e），位于彼此成角度不是零，并且优选是直角，以简单的方式实现均匀照射，因为扫描仪中的电子束（11）产生扫描的电子束（17）借助于扫描装置（13），其通过在规定角度范围内的时间驱动的前后回转运动产生横向于照射材料的纵向方向的辐射风扇，并且扫描电子束（17）被偏转偏转布置在扫描装置（13）和被照射材料（19; 19a-e）以这样的方式对从两个固定照射方向（R1，R2）之一处理的照射材料（19; 19a-e）照射的照射场的每个扫描角度。
