Abstract
An endoluminal medical prosthesis has a frame, a flexible sleeve, and means for fastening the flexible sleeve to the frame. The frame includes a plurality of adjacent, axially-spaced undulating or meandering tubular structures, the undulations or meanders being formed by elongate segments arranged in V- or U-formation, with apices therebetween. The flexible sleeve is substantially coaxial with the frame and channels a fluid flowing in the duct. The attaching element, which includes a flexible thread, wraps around and extends from an elongate segment of one meandering structure of the frame to an elongate segment of an adjacent, axially spaced meandering structure of the frame, preferably passing through the flexible sleeve with each wrap or turn around a segment.
