Abstract
Abstract A stent is made up of a plurality of adjacent stern segments, spaced from one another. Between each two adjacent stent segments is a detachment zone that includes two articulation planes. In each articulation plane there are two connecting members, with the members in one articulation plane spaced from those in the other articulation plane about the circumference of the stent by from about 60 to 140 degrees from each other. Within each articulation plane, the two members are spaced between about 140 and 220 degrees from each other.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
160 words
A stent comprising: a plurality of adjacent stent segments, each made up of a plurality of loop containing sections extending generally in the circumferential direction and which are periodically interconnected, said stent segments spaced from one another; detachment zones, one between each two adjacent stent segments, each detachment zone comprising a single boo containing section extending generally in the circumferential direction periodically connected on each side to a loop containing section in one of said stent segments such as to form two articulation planes, disposed adjacent to each other, in each of which there are two connecting members, with the members in one articulation plane spaced from those in the other articulation plane about the circumference of the stent by from about 60 to 140 degrees from each other, the connecting members in said articulation planes being easily breakable such that the members in at least one of the planes separate under repeated stress placed on the stent after implantation.
Claim 2
Dependent Claim
160 words
A stent comprising: a plurality of adjacent stent segments, each made up of a plurality of loop containing sections extending generally in the circumferential direction and which are periodically interconnected, said stent segments spaced from one another; detachment zones, one between each two adjacent stent segments, each detachment zone comprising a single boo containing section extending generally in the circumferential direction periodically connected on each side to a loop containing section in one of said stent segments such as to form two articulation planes, disposed adjacent to each other, in each of which there are two connecting members, with the members in one articulation plane spaced from those in the other articulation plane about the circumference of the stent by from about 60 to 140 degrees from each other, the connecting members in said articulation planes being easily breakable such that the members in at least one of the planes separate under repeated stress placed on the stent after implantation.
Claim 3
Dependent Claim
25 words
A stent according to claim 1 wherein the two members in each articulation plane are spaced between about 140 and 220 degrees from each other.
Claim 4
Dependent Claim
40 words
A stent according to claim 1 wherein each stent segment is made up of high frequency and low frequency vertical sinusoidal patterns or vertical loop containing sections which are arranged generally in the circumferential direction and which are periodically interconnected.
Claim 5
Dependent Claim
73 words
A stent according to claim 3 comprising a first loop containing section with loops occurring at a first frequency and a second loop containing section with loops also occurring at said first frequency and a third loop containing section having loops occurring at a second frequency that is higher than said first frequency disposed between the first and second loop containing sections and alternately joined to the first and second loop containing sections.
Claim 6
Dependent Claim
20 words
A stent according to claim 4 wherein the high frequency is in a ratio of 3/2 to the low frequency.
Claim 7
Dependent Claim
20 words
A stent according to claim 4 wherein, the higher frequency loop containing elements are smaller in width to provide flexibility.
Claim 8
Dependent Claim
40 words
A stent according to claim 4 wherein, relative widths of high and low frequency loop containing elements are selected so that the high frequency loop containing elements are crimpable to the same diameter as the lower frequency loop containing elements.
Claim 9
Dependent Claim
47 words
A stent according to claim 3 wherein first, second and third low frequency loop containing sections are in each detachment zone joining two stent segments with a first articulation plane between the first and second sections and a second articulation plane between the second and third sections.
Claim 10
Dependent Claim
50 words
The stent according to claim 8 wherein each of said first, second and third sections contain six cycles of loops and said members in said first plane are spaced 90 degrees from the members in said second plane, with members within a plane are spaced 180 degrees from each other.
Claim 11
Dependent Claim
52 words
The stent according to claim 8 wherein each of said first, second and third sections contain eight cycles of loops and said members in said first plane are spaced either 67.5 or 112.5 degrees from the members in said second plane, with members within a plane spaced 180 degrees from each other.
Claim 12
Dependent Claim
56 words
The stent according to claim 8 wherein each of said first, second and third sections contain seven cycles of loops and said members in said first plane are spaced either 76.12 or 127.5 degrees from the members in said second plane, with members within a plane spaced either 152.2 degrees or 207.8 degrees from each other.
Claim 13
Dependent Claim
17 words
A stent according to claim 1 wherein each of the connecting members has a thin cross section.
Claim 14
Dependent Claim
39 words
A stent according to claim 12 wherein each of the connecting members has a cross-sectional area that is sufficiently low to allow fracture of the members and separation under the repeated bending stress placed on the stent after implantation.
Claim 15
Dependent Claim
25 words
A stent according to claim 1 wherein each of the connecting members is made of a material that is weaker than elsewhere in the stent.
Claim 16
Dependent Claim
32 words
A stent according to claim 1 wherein each of the connecting members has a cross-section that is thin and is made of a material that is weaker than elsewhere in the stent.
