Stent capable of attachment within a body lumen

An intraluminal stent implantable in a body lumen, comprising:

• a sheet of material formed of a biocompatible material;
• said sheet curled into a cylinder having overlapping ends;
• said cylindrical sheet having a length and a circumference;
• a plurality of protuberances projecting along the length and circumference of said sheet;
• a plurality of apertures in said sheet of materials, said apertures corresponding in shape to the shape of said protuberances;
• said apertures being formed in said sheet as a result of said plurality of protuberances being formed whereby said cylinder is expanded from a first diameter to a second, enlarged diameter so that said protuberances engage said body lumen.

An expandable intraluminal stent implantable in a body lumen, adapted to expand from a reduced diameter form to an expanded diameter form, comprising:

• a sheet of biocompatible material curled into a cylinder having overlapping edges, an inner surface, and an exterior surface;
• said apertures being formed in said sheet as a result of said plurality of protrusions being formed
• said exterior surface contiguous with said lumen, and said overlapping edges allowing contact between said exterior surface and said interior surface;
• said exterior surface having a surface texture made of a plurality of protrusions projecting along the length and circumference of said exterior surface;
• a plurality of apertures in said sheet of material, said apertures corresponding in shape to the shape of said protrusions said apertures being formed in said sheet as a result of said plurality of protrusions being formed;
• wherein said stent is held in said expanded diameter form to engage said lumen by combining said surface texture of said exterior surface engaging said inner surface and said surface texture of said exterior surface engaging said lumen.
