摘要： One aspect of the invention provides a method for endovascularly replacing a heart valve of a patient. In some embodiments the method includes the steps of endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; expanding the anchor to a deployed configuration in which the anchor contacts tissue at an anchor site; optionally repositioning the anchor in the anchor site; and deploying the anchor at the anchor site. In some embodiments the deploying step include the steps of actively foreshortening the anchor via an actuation force delivered by a deployment tool and thereafter releasing the anchor from the deployment tool. The delivering step may include the step of delivering the replacement heart valve coupled to the anchor or, alternatively, separate from the anchor, in which case the method further includes the step of attaching the replacement valve to the anchor. The anchor may be made from an expandable braid. In some embodiments, the apparatus herein further comprises a lock or a plurality of locks configured to maintain expansion of the braid. The anchor and valve may also be retrieved into a delivery catheter.

摘要： A positioning anchor (10) is provided for a stent-graft (40) for implantation to treat a damaged body lumen. The positioning anchor is generally tubular surrounding a primary fluid conduit (22). Arms (15, 16, 18) extend laterally from the generally tubular structure of the anchor surrounding lateral fluid conduits. The form of these arms is preferably custom configured to match a particular patient's luminal geometry. The anchor thus fits within the luminal geometry to remain in a desired fixed position for implantation of the anchor and any stent-graft (40) coupled to the anchor. The anchor is most preferably formed with two walls (20, 30) having a void (35) there between which can be filled with fixation media (M) to further secure the anchor at the desired implantation site. A lumen shaper balloon and delivery catheter are also disclosed for proper delivery, expansion and inflation of the positioning anchor and stent-graft elements according to this invention.

摘要： A system is provided for high volume print-forming of structures made up of multiple separate layers. A support bed is provided which has multiple steps arrayed thereon at different heights. Substrate blocks rest upon each of the steps. A printing process is utilized to print material from which the structures are to be formed down onto the substrate blocks. This printing process prints different layers onto each of the substrate blocks. The substrate blocks then move to a different step on the support bed and the printing process is repeated. Each support block has a partial structure thereon which receives its next successive layer in each printing cycle until the partial structure becomes a completed structure by having each of its layers sequentially printed thereon. Subsystems are provided for moving the substrate blocks upon the support bed and for properly holding and aligning substrate blocks upon the support bed.
