Abstract

Abstract A stent for use in the treatment of stenosis of the ostium of tubular organs, more particularly, blood vessels comprising a multiplicity of flanges located at an end of a generally tubular stent body. The flanges permit the accurate positioning of the stent within the vessel, while presenting dislodgement of the stent.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 70 words
A stent for use in the treatment of a stenosis at the ostium of a tubular organ, comprising a tubular body capable of pressing against the stenosis to create or maintain an opening and having at one end two or more regularly spaced, substantially flat flaring members which flare to hold the stent in a secure location at said ostium, wherein the flaring members are not all of equal length.
Claim 2
Dependent Claim 70 words
A stent for use in the treatment of a stenosis at the ostium of a tubular organ, comprising a tubular body capable of pressing against the stenosis to create or maintain an opening and having at one end two or more regularly spaced, substantially flat flaring members which flare to hold the stent in a secure location at said ostium, wherein the flaring members are not all of equal length.
Claim 3
Dependent Claim 17 words
The stent of claim 1 for use in the treatment of a stenosis in a blood vessel.
Claim 4
Dependent Claim 13 words
The stent of claim 1 which is fabricated out of a shape-memory material.
Claim 5
Dependent Claim 11 words
The stent of claim 1 which is fabricated out of nitinol.
Claim 6
Dependent Claim 21 words
The stent of claim 1, wherein the tubular body and the flaring members are formed from a continuous piece of material.
Claim 7
Dependent Claim 19 words
The stent of claim 1, wherein the tubular body and the flaring members are formed from two different materials.
Claim 8
Dependent Claim 13 words
The stent of claim 1, wherein the flaring members are of equal length.
Claim 9
Dependent Claim 30 words
The stent of claim 1, wherein each flaring member is capable of expanding to form an angle generally perpendicular to the longitudinal axis of the tubular body of the stent.
Claim 10
Dependent Claim 28 words
The stent of claim 1, wherein the flaring members are formed at an angle of less than 90° with reference to the longitudinal axis of the tubular body.
Claim 11
Dependent Claim 28 words
The stent of claim 1, wherein the flaring members are formed at an angle of more than 90° with reference to the longitudinal axis of the tubular body.
Claim 12
Dependent Claim 33 words
The stent of claim 1, wherein the tubular body and the flaring members are formed from a single continuous piece of material, the tubular body is self-expandable, and the flaring members are self-flaring.
Claim 13
Dependent Claim 15 words
A combination comprising a stent according to claim 1 and a retractable sheath-type delivery system.
Claim 14
Dependent Claim 72 words
A stent for use in the treatment of a stenosis at the ostium of a tubular organ, comprising a tubular body capable of pressing against the stenosis to create or maintain an opening and having at one end two or more regularly spaced, substantially flat flaring members which flare to hold the stent in a secure location at said ostium, wherein the flaring members are formed by incisions in the tubular body.
Claim 15
Dependent Claim 72 words
A stent for use in the treatment of a stenosis at the ostium of a tubular organ, comprising a tubular body capable of pressing against the stenosis to create or maintain an opening and having at one end two or more regularly spaced, substantially flat flaring members which flare to hold the stent in a secure location at said ostium, wherein the flaring members are formed by incisions in the tubular body.
Claim 16
Dependent Claim 40 words
The stent of claim 1, wherein each flat flaring member flares outwardly to form an angle generally perpendicular to the longitudinal axis of the tubular body of the stent to hold the stent in a secure location at said ostium.
