Implant having improved fixation to a body lumen and method for implanting the same

A method for implanting a device in a body lumen comprising the steps of:

• introducing a device into a body lumen, wherein said device comprises:
• a prosthetic component having a proximal end and a distal end and comprising a graft extending between said proximal end and said distal end and having a hem formed on said proximal end or said distal end, wherein said hem defines an interior space;
• and a cord disposed within said interior space for expanding upon absorbing fluid;
• and
• contacting said cord with fluid to aid in fixating said prosthetic component against said body lumen.

A device for implantation in a body lumen comprising:

• a prosthetic component having a proximal end and a distal end and comprising a graft having a first hem formed on said graft at said distal end, wherein said hem defines a first interior space, and a second hem formed on said graft at said proximal end, wherein said second hem defines a second interior space;
• a first cord disposed within said first interior space adapted for expanding upon absorbing fluid for aiding in fixating said prosthetic component against said body lumen;
• and
• a second cord adapted for expanding upon absorbing fluid for aiding in fixating said prosthetic component against said body lumen disposed within said second interior space.

A method of implanting a device in a body lumen comprising the steps of:

• compressing said device into an introducer wherein said device comprises:
• a prosthetic component comprising a graft having a hem formed on said graft, wherein said hem defines an interior space and a cord disposed within said interior space for expanding upon absorbing said fluid;
• inserting said introducer into said body lumen;
• positioning said introducer such that said compressed prosthetic component is at a predetermined location within said body lumen;
• withdrawing said introducer to expand the prosthetic component to its decompressed size at said predetermined location within the body lumen;
• and
• contacting said cord with fluid to aid in fixating said prosthetic component against said body lumen.

A method of implanting a device in a body lumen comprising the steps of:

• introducing said device into said body lumen wherein said device comprises:
• a prosthetic component comprising a graft having a hem formed on said graft, wherein said hem defines an interior space;
• and a cord disposed within said interior space for expanding upon absorbing said fluid to aid in fixating said prosthetic component against said body lumen;
• aligning an outside circumference of the hem within an inside diameter of said body lumen;
• and
• removing an impediment to a flow of a fluid within said body lumen to said cord, to allow said fluid to contact said cord.
