    摘要: An endoluminal prosthesis for treating a diseased portion of the ascending aorta includes a tubular graft material having an outer surface and an inner surface and a support structure coupled to the graft material. An anchoring device is coupled to the proximal end of the support structure to engage the sinotubular junction or the sinuses adjacent the sinotubular junction. The anchoring device may be a stent ring with barbs on an outer surface to engage the sinotubular junction, a plurality of anchors extending into the sinuses including hooks to engage the sinuses, a plurality of bent stents with distally facing shoulders extending into the sinuses and engaging a distal edge of the sinuses, or a series of progressively larger diameter stent rings extending into the sinuses to engage the distal edge of the sinuses.

    摘要: A method of deploying a stent-graft in a curved vessel includes deploying an expandable tip to center a proximal end of the catheter containing a stent-graft in the curved vessel. A sheath is retracted to expose the stent-graft and the stent-graft self-expands into the curved vessel. By centering the catheter containing the stent-graft prior to deployment with the expandable tip, the accuracy of stent graft placement within the curved vessel is improved.

    摘要: A comfortable insert comprises a retention structure sized for placement under the eyelids and along at least a portion of conjunctival sac of the upper and lower lids of the eye. The retention structure resists deflection when placed in the conjunctival sac of the eye and to guide the insert along the sac when the eye moves. The retention structure can be configured in many ways to provide the resistance to deflection and may comprise a hoop strength so as to urge the retention structure outward and inhibit movement of the retention structure toward the cornea. The insert may move rotationally with deflection along the conjunctival sac, and may comprise a retention structure having a cross sectional dimension sized to fit within folds of the conjunctiva. The insert may comprise a release mechanism and therapeutic agent to release therapeutic amounts of the therapeutic agent for an extended time.
