Abstract
Abstract Expandable ring or cylinder (so-called "stent") for locally supporting or strengthtening a body vessel, particularly a blood vessel, and which is filled with curable material which cures when the stent is brought at the desired position in the vessel by means of a catheter or dotter - like device. <IMAGE>

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
54 words
Ring or cilinder, particularly for locally supporting or strenghtening a body vessel comprising a body able to maintain a desired shape after its positioning at the desired location, characterised in that said body is hollow and contains curable material which can cure after the positioning and thus assures that the desired shape is maintained.
Claim 2
Dependent Claim
62 words
Device according to claim 1, characterised in that , the hollow body is devided into at least two compartments which are separated from eachother by at least one partition which can be broken, the compartments each being filled with a first and a second substance respectively, the mixing together of which leads to a reaction resulting in curing of the produced mixture.
Claim 3
Dependent Claim
30 words
Device according to claim 2, characterised in that said partition has such a configuration that, when the diameter of the element is increased, a passage is opened between the compartments.
Claim 4
Dependent Claim
23 words
Device according to claim 3, characterised in that the partition runs concentrically with the outer limits of the element about its central axis.
Claim 5
Dependent Claim
16 words
Device according to claim 4, characterised in that the partition is parallel to the central axis.
Claim 6
Dependent Claim
19 words
Device according to claim 4 , characterised in that the partition lies at right angles to the central axis.
Claim 7
Dependent Claim
15 words
Device according to claim 3, characterised in that the partition (s) runs or run radially.
Claim 8
Dependent Claim
23 words
Device according to claims 3 - 7, characterised in that the partition(s) is (are) made of material which tears when put under tension.
Claim 9
Dependent Claim
49 words
Device according to claims 7 - 8, characterised by a nymber of compartments distributed along its periphery and filled alternately with a first and a second substance, all this in such a way that when connections are made between them the reaction starts simultaneously over essentially the entire periphery.
Claim 10
Dependent Claim
15 words
Device according to claims 3 - 9, characterised by a weakened part in a partition.
Claim 11
Dependent Claim
18 words
Device according to claims 3 - 10, characterised by an opening in a partition which expands on stretching.
Claim 12
Dependent Claim
25 words
Device according to claims 3 - 11, characterised by a part which disintegrates after a predetermined period and thus clears an opening in a partition.
Claim 13
Dependent Claim
31 words
Device according to claims 2 - 12, characterised in that the curing material is of the kind of which the curing starts a predetermined period after the mixing of its components.
Claim 14
Dependent Claim
26 words
Device according to claim 1, characterised by means for introducing the curing material in said hollow body when same has been positioned at the desired location.
Claim 15
Dependent Claim
33 words
Device according to claims 1 - 14, characterised in that its shape makes it possible to hold it around an uninflated dotter - like device during the insertion thereof in a body vessel.
Claim 16
Dependent Claim
18 words
Device according to claim 15, characterised in that the body is spirally wound around the uninflated dotter device.
Claim 17
Dependent Claim
34 words
Device according to claims 15 - 16, characterised in that the body is fixed to the dotter - like device by means of threads which break when the dotter - like device is inflated.
Claim 18
Dependent Claim
33 words
Device according to claim 17, characterised in that the curable material is of the kind of which the curing is started or accelerated under the influence of radiation with a suitable wave length.
Claim 19
Dependent Claim
13 words
Device according to claim 18, characterised in that said radiation is UV light.
Claim 20
Dependent Claim
23 words
Device according to claim 18-19, characterised by a light conducting fiber for transmitting the radiation from an outside source to the curable material.
