Problems solved by technology

[0003] This method is very cumbersome by stopping and necessarily manually rearranging the mallets
Furthermore, holes are formed between the secondary strands, which prevent optimal functioning of the braided structure as a scaffold

Embodiment Construction

[0048] In the following description of the alternative exemplary embodiment, the same reference numerals are used for configurations and / or features having the same and / or at least similar effect as the other exemplary embodiments. If the features are not described in detail again, their configuration and / or effect correspond to those of the previously mentioned features.

[0049] exist figure 1 A braided structure 1 is shown in , which is known in the prior art. The braided structure 1 has one primary strand 2 and two secondary strands 3 . The individual monofilaments 4 woven into the braided structure 1 are not shown in the figures. Here, the sum of the individual filaments 4 woven into the secondary strand 3 is equal to the sum of the individual filaments 4 woven into the primary strand 2 . Different, almost endless, elongated formations, in particular threads and threads, are referred to here as monofilaments 4 .

Abstract

The present invention relates to a braided structure (1) having a primary limb (2) and at least two secondary limbs (3), wherein the primary limb (2) is braided from a group of filaments (4), in particular threads or wires, and the secondary limbs (3) are braided from filaments (4) such that the totality of the filaments (4) associated with the secondary limbs (3) is the same as the group of filaments (4) of the primary limb (2). The invention proposes that a transitional region (7) braided from the group of filaments (4) of the primary limb (2) is arranged between the primary limb (2) and thesecondary limbs (3). The invention further relates to a method for braiding a braided structure (1), in particular a stent, having a primary limb (2) and at least two secondary limbs (3), wherein theprimary limb (2) is first braided from a group of filaments (4), a substantially hole-free transitional region (7) is then braided from the group of filaments (4) of the primary limb (2), and the secondary limbs (3) are then braided, or the method steps are carried out in the reverse order.

Description

technical field [0001] The invention relates to a braided structure, in particular a stent, which has a primary strand and at least two secondary strands, wherein the primary strand is woven from all monofilaments, in particular threads or threads, and the secondary strand is woven from monofilaments formed so that the sum of the monofilaments assigned to the secondary strands is equal to the sum of the monofilaments. The invention also relates to a method for weaving a braided structure, in particular a stent, with a primary strand and at least two secondary strands, wherein first the primary strand is woven from all monofilaments, in particular threads or threads, and then the secondary strands are woven. class stock, or carry out the method steps in reverse order. Background technique [0002] In a weaving structure of this type, for example, the primary strand is first woven from all the monofilaments. The hammer for the first secondary strand is thereafter rearranged ...
