Preferably, between the cutting portion of two free ends connected described in, laser weld is fixed.
Preferably, fix for laser weld is fixed or clamp deformation between described connection tube and split portion.
The beneficial effects of the utility model are embodied in:
1. the split portion of braided wires free end and connection tube seamless link;
2. the free end of braided wires all has cutting portion, and the split portion diameter of free end split is consistent with braided wires diameter, reduces the diameter in split portion, and free end radial force and axial force are evenly distributed;
3. the cutting portion of free end adds the contact area between free end, is convenient to carry out laser weld;
4. seamless support flexibility is good, aesthetic property is excellent.

Fig. 2 is the axonometric chart of the free end of braided wires in a kind of seamless support of this utility model.
Fig. 3 is the axonometric chart of connection tube in a kind of seamless support of this utility model.
Detailed description of the invention
This utility model provides a kind of seamless support, for getting involved internal blood vessel, as shown in Figure 1 to Figure 3, seamless support is worked out by least one braided wires 1, braided wires 1 has even number free end 2, free end is the joint of braided wires, every root braided wires all has two free ends, namely the plural braided wires forming seamless support possesses even number free end, the free end 2 of braided wires 1 docks between two, joint is the mosaic hereafter mentioned, be tubular structure by the support after braided wires 1 coiling, the free end 2 of braided wires 1 all has cutting portion 3, the cutting portion 3 of two free ends 2 connected is seamless spliced is the diameter split portion 4 consistent with braided wires 1 diameter, in split portion 4, overcoat has connection tube 5, connection tube is C-Clip pipe, there is an axially open, press off mouth by pincers can close, this opening is also convenient to laser weld simultaneously, the inwall of connection tube 5 and the outer wall seamless link in split portion 4.
Further refinement describes the architectural feature of seamless support in this programme, seamless support is formed by dextrorotation and poor the folding of derotation by braided wires 1, seamless support has the rhombus NE enclosed by dextrorotation braided wires and derotation braided wires, and the dextrorotation of braided wires and derotation switching part are the convolution fillet part at seamless support two ends.This is a kind of preferred structure feature of this seamless support.Further restriction, the scope at the obtuse angle of network unit is 91 degree of-179 degree.The shape of cross section of braided wires is circular, oval, trapezoidal or rectangle.Braided wires can be Nitinol braided wires, platinum braided wires, golden braided wires, tantalum braided wires etc.
For optimizing this programme, the cutting portion of free end 2 is semicylinder, and convenient cutting and splicing, two semicylinders can just split be a full circle cylinder.
