Problems solved by technology

[0008] A problem with known helical stents is that the connections between the individual loops are structurally complex and expensive and / or the edges are not evenly firmly connected to each other
Uneven connection of the edges causes the necessary release force to manually unfold the extruded body to fluctuate greatly, so separation of the connected edges when releasing the helical stent becomes difficult or impossible manually or the helix breaks

Embodiment Construction

[0043] First, refer to figure 1 with 2 And the exemplary embodiment shown therein describes the general construction of the helical stent 1 according to the invention.

[0044] The helical support 1 consists of an extruded body 2 wound in a winding direction W with a plurality of loops 15 .

[0045] The extruded body 2 is configured as a substantially continuous strip-shaped body, which is produced, for example, by an extrusion method. In this way, theoretically, the helical stent 1 can be manufactured to an infinite length. In practice, the helical stent 1 is usually about 30 to 50 cm long. In cross-section, the extruded body 2 is at figure 1 , 2 The embodiment shown in and 9 is substantially rectangular with parallel upper and lower edges 3,4 and shorter side edges 5,6. The side edges 5, 6 match each other. The rectangular protrusion 7 is arranged on the edge 6 side, and the rectangular groove 8 is arranged on the edge 5 side. The protrusion 7 and the groove 8 are fo...

Abstract

The invention relates to a tubular helical support (1) for the radial support of elastically expanded tube material (26) and a method for the production thereof. The helical support (1) is constructed of at least one extruded body (2) wound to form several windings (15), the edges (5, 6) of which are connected to one another in the longitudinal direction (L) of the helical support (1) at least inportions. In order to provide a helical support (1) which reliably withstands the pressure forces of the expanded tube material (26) and which can easily be removed from the tube material (26), it isprovided according to the invention that the edges (5, 6) are connected to one another by at least one laser weld seam (16).

Description

technical field [0001] The invention relates to a tubular helical stent for radially supporting elastically expandable tubing, comprising at least one extruded body wound to form a plurality of loops, the edges of which are helically helical at least in certain regions. The longitudinal directions of the supports are connected to each other. Background technique [0002] Helical supports of this type are known in the art and are used to hold tubing, such as for example insulating tubes and sleeve bodies, in an expanded state prior to assembly. Insulation tubes are used in electrical engineering such as, for example, cable splices or cable plug-in connectors for the electrical insulation and sealing of electrical components. Since high voltages, for example above 100 kv, may be applied to these elements, the insulating tube is constructed with thick walls and made of a material with good electrical insulating properties, such as silicone. In the assembled state, the insulat...
