摘要:
A plurality of endoluminal segments axially connected by fiber bridges is disclosed. The endoluminal segments may be superelastic nitinol that is balloon-expandable or self-expanding. The intraluminal segments may possess a textured surface or at least one geometric feature per segment, located at the apex of a strut pair comprising the intraluminal segment, serving as an anchoring point for the fiber bridges. These geometric features may transmit axially compressive loads during deployment from a device such as a catheter, and may be capable of interlocking the endoluminal segments when constrained within a device such as a catheter. The fibers comprising the bridges may be polymeric, silk, collagen, bioabsorbable, or a blend thereof. The fiber network comprising the bridges may be regularly oriented, randomly oriented, localized, or continuous. The intraluminal segments and fiber bridges may be individually impregnated with therapeutic material, or may both be impregnated with therapeutic material.
