Expandable medical device with an end structure having a transitional surface

An intraluminal expandable medical device, comprising:

• an expandable structure comprising a delivery configuration and an expanded configuration;
• and
• an end structure attached to an end of said expandable structure comprising an outer surface generally contiguous with an outer surface of said expandable structure, a thickness extending between said outer surface of said end structure and an inner surface of said end structure, and an end surface facing away from said expandable structure, said end surface being generally perpendicular to said outer surface of said end structure;
• wherein said end structure comprises a transitional surface extending between said end surface and said outer surface of said end structure, said transitional surface being disposed between a first plane defined by 10% of said thickness from said outer surface of said end structure and a 10° angle extending therefrom to said outer surface of said end structure and a second plane defined by 90% of said thickness from said outer surface of said end structure and a 60° angle extending therefrom to said outer surface of said end structure.
