Abstract
Abstract A new endoluminal prosthesis for use in sealing a vascular graft to corporeal lumen provides for a flattened bulbous tail at the end of each cell of the prosthesis. The flattened bulbous tails reduce the amount of wear between the prosthesis and the softer material of the vascular grafts or corporeal lumen walls. A method of manufacturing a stent from a flat sheet of material is also included.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A prosthesis, comprising: a plurality of cells defined by struts having a first width, each cell having a bottom end and a top end, the struts defining a surface exterior of the cell; a flattened bulbous tail attached to the surface exterior of the cell adjacent the bottom end of at least more than one of the cells; and a flattened bulbous tail attached to the surface exterior of the cell adjacent the top end of at least more than one of the cells; wherein the flattened bulbous tails include a perimeter, a tail surface extending across a lateral face of the tail surface bounded by the perimeter, the lateral surface having a second width greater than the first width.
Claim 2
Dependent Claim
120 words
A prosthesis, comprising: a plurality of cells defined by struts having a first width, each cell having a bottom end and a top end, the struts defining a surface exterior of the cell; a flattened bulbous tail attached to the surface exterior of the cell adjacent the bottom end of at least more than one of the cells; and a flattened bulbous tail attached to the surface exterior of the cell adjacent the top end of at least more than one of the cells; wherein the flattened bulbous tails include a perimeter, a tail surface extending across a lateral face of the tail surface bounded by the perimeter, the lateral surface having a second width greater than the first width.
