Abstract
Abstract ENDOVASCULAR EXPANDER, OF NON MIGRANT POSITIONING; including a tubular body--generally structured by a wire mesh--which, tensed in the sense of its diametrical expansion against the internal surfaces of the vessel of application, is able to be introduced in it in order to maintain or increase the lumen of said vessel; wherein, outwardly, the expander has a plurality of unidirectional anchorages in proximal arrangement to said tubular body and in the sense of its generatrix; each one of said anchorages possesses two opposite ends of--union to the body of the expander and of vascular anchorage, respectively--of which: that one of union is articulable with respect to said body, while that one of vascular anchorage, as of said link is projected freely in proximal arrangement to the body of said expander; so that, being said endovascular expander applied--the anchorage ends being oriented in equal direction to that of the flow of the bloodstream--said anchorages are capable of opening in contraposition to the migrant effect of the expander.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
An endovascular expander to be placed in a vessel carrying a bloodstream and to be retained in place, said endovascular expander comprising: a support forming said endovascular expander and a plurality of anchorage elements, wherein the anchorage elements are aligned in a plurality of rows which are overlapped one to each other, said plurality of anchorage elements having a general fish scale structure to prevent migration of the endovascular expander, wherein one end of each of said anchorage elements is connected to said support, and the other respective ends of said anchorage elements are free, whereby said anchorage elements open when pressured by blood flow and attach to the wall of the vessel thereby preventing the migration of the endovascular expander.
Claim 2
Dependent Claim
121 words
An endovascular expander to be placed in a vessel carrying a bloodstream and to be retained in place, said endovascular expander comprising: a support forming said endovascular expander and a plurality of anchorage elements, wherein the anchorage elements are aligned in a plurality of rows which are overlapped one to each other, said plurality of anchorage elements having a general fish scale structure to prevent migration of the endovascular expander, wherein one end of each of said anchorage elements is connected to said support, and the other respective ends of said anchorage elements are free, whereby said anchorage elements open when pressured by blood flow and attach to the wall of the vessel thereby preventing the migration of the endovascular expander.
Claim 3
Dependent Claim
16 words
An endovascular expander, as claimed in claim 1, wherein said support is comprised of wire mesh.
Claim 4
Dependent Claim
20 words
An endovascular expander, as claimed in claim 1, wherein each of said anchorage elements is articulately connected to said support.
Claim 5
Dependent Claim
14 words
An endovascular expander, as claimed in claim 1, wherein the anchorage elements comprise plates.
Claim 6
Dependent Claim
14 words
An endovascular expander, as claimed in claim 1, wherein the anchorage elements comprise wires.
Claim 7
Dependent Claim
32 words
An endovascular expander, as claimed in claim 1, wherein the anchorage elements comprise a wire bent in zigzag, whose crests form alternately the ends connected to said support and the free ends.
Claim 8
Dependent Claim
18 words
An endovascular expander, as claimed in claim 1, wherein each of the anchorage elements has a filiform configuration.
Claim 9
Dependent Claim
103 words
An endovascular expander to be placed in a vessel carrying a bloodstream and to be retained in place, said endovascular expander comprising: a support forming said endovascular expander and a plurality of anchorage elements, wherein the anchorage elements are aligned in a plurality of rows which are overlapped one to each other, wherein one end of each of said anchorage elements is connected to said support, and the other respective ends of said anchorage elements are free, whereby said anchorage elements open when pressured by blood flow and attach to the wall of the vessel thereby preventing the migration of the endovascular expander.
Claim 10
Dependent Claim
103 words
An endovascular expander to be placed in a vessel carrying a bloodstream and to be retained in place, said endovascular expander comprising: a support forming said endovascular expander and a plurality of anchorage elements, wherein the anchorage elements are aligned in a plurality of rows which are overlapped one to each other, wherein one end of each of said anchorage elements is connected to said support, and the other respective ends of said anchorage elements are free, whereby said anchorage elements open when pressured by blood flow and attach to the wall of the vessel thereby preventing the migration of the endovascular expander.
