Claim Text:
1. A medical device for implantation in a bodily vessel of a patient to form a tubular graft anchored and supported in position by tissue of the patient, comprising: a) an implantable graft structure, the implantable graft structure comprised of a tubular body of persistent material having a first face on an exterior of the tubular body and configured for opposing a bodily vessel wall upon implantation, and a second face on an interior of the tubular body, wherein said persistent material comprises a first longitudinal region containing one or more openings extending from the first face to the second face, a second longitudinal region that does not contain openings extending from the first face to the second face, and a third longitudinal region containing one or more openings extending from the first face to the second face, wherein the second longitudinal region is positioned longitudinally between the first longitudinal region and the third longitudinal region; b) a tissue ingrowth material positioned against the second face on the interior of the tubular body and extending over the one or more openings in the first longitudinal region and the third longitudinal region and beyond edges of the one or more openings in the first longitudinal region and the third longitudinal region to cover regions of the second face around the one or more openings in the first longitudinal region and third longitudinal region, the tissue ingrowth material configured for receiving tissue ingrowth from the bodily vessel wall effective to anchor the graft structure to the bodily vessel wall with ingrown tissue of the patient; and c) a first bioabsorbable expandable frame element positioned within the first longitudinal region of the tubular body and a second bioabsorbable expandable frame element discrete from the first bioabsorbable expandable frame element and positioned within the third longitudinal region of the tubular body, the first bioabsorbable stent expandable frame element and the second expandable bioabsorbable frame element effective when expanded to hold the tubular body of persistent material in place in the bodily vessel for a duration sufficient for tissue ingrowth from the bodily vessel wall into the tissue ingrowth material so as to anchor the graft structure to the bodily vessel wall with ingrown tissue of the patient, the at least one first and second bioabsorbable frame elements thereafter being bioabsorbed to leave the tubular body of persistent material supported by the ingrown tissue of the patient.
