Abstract
Abstract A stent shaped as a three-dimensional body which is formed by interlaced threads ( 1 ) arranged in multistart turns of a helical line. The threads ( 1 ) are arranged in at least two groups ( 2 and 3 ) of the helical turns featuring opposite senses of helix. The stent ends are established by sections ( 5 ) where the turns of one helical line merge into those of the other helical line, said sections appearing as a single length of the thread ( 1 ).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
A method for reconstructing a body lumen using a reconstructive device having similar physic-mechanical properties along an entire length of the device, comprising: gaining access to a body lumen of a patient; advancing the reconstructive device to a reconstruction site; deploying the reconstructive device at the reconstruction site; and configuring the reconstructive device at the reconstruction site in a manner to allow the entire length of the device to become functionally active construction elements capable of exhibiting similar physic-mechanical properties.
Claim 2
Independent Claim
80 words
A method for reconstructing a body lumen using a reconstructive device having similar physic-mechanical properties along an entire length of the device, comprising: gaining access to a body lumen of a patient; advancing the reconstructive device to a reconstruction site; deploying the reconstructive device at the reconstruction site; and configuring the reconstructive device at the reconstruction site in a manner to allow the entire length of the device to become functionally active construction elements capable of exhibiting similar physic-mechanical properties.
Claim 3
Dependent Claim
22 words
The method of claim 1 , further comprising configuring the reconstructive device so that its length acquires the properties of a spring.
Claim 4
Dependent Claim
38 words
The method of claim 1 , wherein the reconstructive device has a first end and a second end and further comprising configuring the reconstructive device so that its first and second ends acquire the properties of a spring.
Claim 5
Dependent Claim
31 words
The method of claim 1 , further comprising forming the reconstructive device by crossing portions of the single thread, the crossing portions being configured to slide with respect to one another.
Claim 6
Dependent Claim
17 words
The method of claim 1 , further comprising forming the reconstructive device by interlacing elastic thread portions.
Claim 7
Dependent Claim
20 words
The method of claim 5 , further comprising configuring the elastic thread portions into multi-start turns of a helical line.
Claim 8
Dependent Claim
15 words
The method of claim 1 , further comprising placing the reconstructive device at a stenosis.
Claim 9
Dependent Claim
18 words
The method of claim 1 , further comprising placing the reconstructive device in the area of an aneurysm.
Claim 10
Dependent Claim
21 words
The method of claim 1 , wherein the reconstructive device is self-expanding and further comprising allowing the reconstructive device to self-expand.
Claim 11
Dependent Claim
19 words
The method of claim 1 , further comprising configuring the reconstructive device to have a low interlacing density pattern.
Claim 12
Dependent Claim
32 words
The method of claim 10 , further comprising deploying the reconstructive device in a manner to reduce the reaction of the reconstruction site to the low interlacing density of the reconstructive device.
