AI Technical Summary

Problems solved by technology

The ~4% deformability of the ring limits the elastic recovery effect of the steel second implant after implantation
However such rings have very limited deformability
In particular, the annular helical spring that provides the elasticity of the ring is held very rigidly in the curved edge of the opening, which greatly limits the deformability

Embodiment Construction

[0044] Figure 1 to Figure 4 A first treatment device 10 according to the invention is shown. The first therapeutic device 10 is intended to be implanted in a defined lumen in the human or animal body.

[0045] refer to figure 2 , the lumen comprises a tubular main section 12 and branches 14 connected to the main section 12 .

[0046] The main segment 12 and the branches 14 are, for example, blood circulation conduits in the vascular system of humans or animals. The main segment 12 is, for example, an artery or a vein, while the branches 14 are blood circulation conduits connected to the artery or vein.

[0047] In particular, segment 12 may be the aorta, particularly at the aortic arch, or a linear segment of the aorta connected by segments of the abdominal aorta.

[0048] The first treatment device 10 includes a first implant 16 and an elastic ring 18 .

[0049] In addition, if figure 1 and 2 As shown, the first therapeutic device 10 includes at least one second impl...

Abstract

The invention relates to an elastic ring (18), defining an inner opening, an outer contour (42) and an annular bearing surface between the inner opening and the outer contour (42), the ring (18) beingdeformable between a rest position and an introduction position in which the inner opening has a diameter greater than its diameter in the rest position, the ring (18) being elastically biased towards the rest position. The ring (18) comprises at least three strands (60) passing through the ring (18), each strand (60) comprising a first end (62) and a second end positioned on the outer contour (42), the inner contour of the opening being defined by a portion of each strand (60) and having a pseudo-polygonal shape.

Description

technical field [0001] The invention relates to an elastic ring defining an inner opening, an outer contour and an annular bearing surface between the inner opening and the outer contour, said ring being deformable between a rest position and an inserted position, said inner opening in the inserted position Having a diameter greater than the inner opening in the rest position, the ring is resiliently biased towards the rest position. [0002] The invention also relates to a therapeutic device comprising such an elastic ring arranged in a hole in the body of the implant. Such therapeutic devices are intended to be implanted in cavities of living organisms. This cavity is the area of ​​the circulation network for body fluids. The bodily fluid comprises at least one conduit for circulation of the bodily fluid, such as a blood circulation conduit. Furthermore, the network comprises, for example, branches protruding laterally from the first conduit. For example, in the region o...
