    摘要: An embodiment is directed to an embolic device comprised of a coil made of a first material and disposed on the inside of a tube structure made of a second material. The tube structure has micro-fabricated fenestrations formed in the tube to provide fluid communication between the lumen of the tube and the surrounding environment, thereby exposing the inner coil. The fenestrations also trip flow around the embolic device. In one embodiment, the embolic device is comprised of a tantalum coil on the inside of a polyetheretherketone (PEEK) tube. The PEEK tube has the advantage of providing a micro-machined delivery implant frame and radiopacity, while the internal tantalum coil provides radiopacity and thrombogenicity. A material other than PEEK may be used for embodiments of embolic devices without departing from the spirit of the disclosure.

    摘要: A tissue thickness compensator may generally comprise a compressible core comprising a plurality of movable particles, and a wrap surrounding the compressible core. The plurality of movable particles may comprise at least one medicament. A tissue thickness compensator may generally comprise a compressible core comprising a plurality of crushable particles, and a wrap surrounding the compressible core. The plurality of crushable particles may comprise at least one medicament. The compressible core may comprise a material selected from a group consisting of a biocompatible material. The wrap may comprise a material selected from a group consisting of a biocompatible material. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.

    摘要: A sealant is provided for sealing a puncture through tissue that includes an elongate first section including a proximal end, a distal end, and a cross-section sized for delivery into a puncture through tissue, and a second section fused to and extending from the distal end of the first section. The first section may be formed from a freeze-dried hydrogel that expands when exposed to physiological fluid within a puncture. The second section may be formed from a solid mass of non-freeze-dried, non-crosslinked hydrogel precursors, the precursors remaining in an unreactive state until exposed to an aqueous physiological, whereupon the precursors undergo in-situ crosslinking with one another to provide an adhesive layer bonded to the first section. Apparatus and methods for delivering the sealant into a puncture through tissue are also provided.
