Stent capable of attachment within a body lumen

A method of securing a stent within a body lumen, comprising:

• placing a stent over an expandable catheter, said stent having a length and circumference, a plurality of protrusions about said length and circumference, and a plurality of apertures about said length and circumference;
• introducing the stent and expandable catheter into a body lumen;
• positioning said stent at a desired location in the body lumen with said expandable catheter;
• expanding said expandable catheter to expand said stent from a reduced diameter to an enlarged diameter form;
• and
• securing said stent in said enlarged diameter form at the desired location in said body lumen, said securement occurring through said protrusions securing said stent in its enlarged diameter form, said protrusions engaging against walls of said body lumen.

A method of securing a stent within a body lumen, comprising:

• placing a stent over an expandable catheter, said stent having a length and circumference, a plurality of protrusions projecting along said length and circumference, and a plurality of apertures about said length and circumference, said apertures corresponding to the shape of the protrusions;
• introducing the stent and expandable catheter into a body lumen;
• positioning said stent at a desired location in the body lumen with said expandable catheter;
• expanding said expandable catheter to expand said stent from a reduced diameter to an enlarged diameter form;
• locking said stent in said .enlarged diameter form, said locking occurring through one or more of the protrusions engaging one or more of the apertures;
• and
• securing said stent at the desired location in said body lumen, said securement occurring through said protrusions engaging against walls of said body lumen.
