First Claim
Patent Images
1. A method of stenting the ostium of a tubular organ, comprising the step of inserting a stent 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.

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.

10. A method of stenting the ostium of a tubular organ comprising the steps of:
-
collapsing a stent 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, with a retractable sheath type delivery system, inserting the stent/retractable sheath type delivery system into the ostium of a tubular organ, and retracting the sheath to permit the stent flanges to recover their original shape. - View Dependent Claims (12, 13, 14, 15, 16, 17)
