摘要： A method for forming a molded grommet using a device which includes a fixed mold and a movable mold, the latter having three positions. The first is a closed position, wherein the two molds are adjacent each other with a middle plate between them. Second, there is an intermediate position in which the middle plate and movable mold are spaced apart from the fixed mold. Third, there is an open position, wherein the movable mold is spaced further from the fixed mold than the middle plate. A core is fixed to the movable mold and, when in the closed position; the two molds, the core, and the edge of the middle plate define the molding space into which moldable resin is introduced, thereby forming the grommet with the edge within the channel. As the core moves from the intermediate position to the open position, the middle plate is retained in the intermediate position; therefore, the core is pulled out of the grommet through the axial hollow therein. In a preferred form of the device, a retaining element on the end of the core pulls the adjacent end of the grommet into the axial hollow. The grommet is then removed from the edge and any unwanted peripheral material is cut off. The core can be pulled out either in the direction of movement of the movable mold or an angle (preferably 90°) thereto.
摘要翻译：一种使用包括固定模具和可动模具的装置形成模制密封垫圈的方法，该模具具有三个位置。第一个是闭合位置，其中两个模具彼此相邻，在它们之间具有中间板。其次，存在中间位置，中间板和活动模具与固定模具间隔开。第三，存在打开位置，其中可移动模具比固定模具更远离中间板。芯子固定在可动模具上，当处于关闭位置时; 中间板的两个模具，芯部和边缘限定了可塑树脂引入其中的模制空间，从而在通道内与边缘形成索环。当芯从中间位置移动到打开位置时，中间板保持在中间位置; 因此，芯通过其中的轴向中空被拉出索环。在装置的优选形式中，在芯的端部上的保持元件将索环的相邻端部拉入轴向中空部。然后将护环从边缘移除，并且切断任何不需要的周边材料。芯可以在可移动模具的移动方向上拉出或与其成角度（优选为90°）拉出。

摘要： A method of forming a thin-walled polymeric tubular member for an intralumenal device, and the member produced thereby. The thin-walled tubular member extruded using the method of the invention is suitable for use a sleeve for a catheter shaft or balloon. The thin-walled tubular member has a single wall thickness of not greater than about 0.003 inch (0.0076 cm). In the method of the invention, the thin-walled tubular member is formed by co-extruding a thin-walled first polymer layer with a removable second polymer layer, and the two layers are separated by dissolution or physical removal of the second layer, to leave the first layer, with the first polymer layer forming the thin-walled tubular member. Because the method of the invention involves co-extruding a removable second polymer layer along with the thin-walled first polymer layer, conventional tooling dimensions in the extruder may be used.

摘要： A method of shaping three-dimensional products by manipulating an expanded polytetrafluoroethylene tubular body into a desired three-dimensional conformation. The present invention entails radially expanding a longitudinally expanded polytetrafluoroethylene (ePTFE) tube to form a radially expanded ePTFE (rePTFE) tube, engaging the rePTFE tube circumferentially about a shaping mandrel, heating the assembly to a temperature below the crystalline melt point temperature, or sintering temperature, of polytetrafluoroethylene to radially shrink the diameter of the rePTFE tube into intimate contact with the shaping mandrel, and heating the assembly to a temperature above the crystalline melt point temperature of polytetrafluoroethylene to amorphously lock the microstructure of the shaped polytetrafluoroethylene body.

摘要： The present invention relates to a method intended for heat insulation of a pipe (1), comprising the following successive stages: depositing, on the outer surface of the pipe moving longitudinally, a thickness (3) of an insulating material made of elastomer having an elastic type behaviour, substantially without irreversible plastic deformation, forming at least one circumferential slot (4) in the thickness of the material, substantially orthogonally to the axis (2) of the pipe, coating the insulating material thickness with a sealed sheath. In a variant, the slot is machined in the thickness of the insulant. The invention further relates to a heat-insulated pipe.
