    摘要： A vascular implant may comprise at least a first layer having one or more drawn fill tube wires (DFT wires) and at least a second layer having one or more non-DFT wires. The first layer may be braided from only a single DFT wire, and the second layer may be braided from a plurality of non-DFT wire. A vascular implant may also include a connecting wire composed of a shape memory alloy and that is shape set prior to connection to one or more implant layers composed of DFT wires.

    摘要： A device for treatment of a vascular defect within a patient's vasculature includes a self-expanding permeable shell having a proximal end, a distal end, and a longitudinal axis, the shell comprising a plurality of elongate resilient filaments having a braided structure, wherein the filaments are secured at at least one of the proximal end or the distal end of the permeable shell, wherein the permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with an axially shortened configuration relative to the radially constrained state, the permeable shell having a plurality of openings formed between the braided filaments, wherein the permeable shell in its expanded state comprises a plurality of circumferentially-arrayed lobes.

    摘要： Described herein are syringe caps including a plug portion and a protruding member extending from one end of the plug portion. The protruding member can extend a length greater than a depth of an accumulated component in the syringe. Also described herein, are systems including a syringe containing a composition and a syringe cap. The syringe cap can include a luer-lock with a projecting member that projects into the syringe. The projecting member can assist in creating a tunnel through the accumulated material thereby allowing degassing of the composition. The projecting member can also help to prevent accumulation of a radiopaque visualization agent or contrast agent that may accumulate along one end of the syringe.
