摘要： Methods, systems, and kits for treating unruptured brain arteriovenous malformations in a human patient with reduced procedure time by embolizing by delivering a first embolic agent comprising N-butyl cyanoacrylate (“n-BCA”) within at least one blood vessel adjacent a vascular tangle in a first group of human patients and achieving a reduced embolization procedure time compared to a second group of human patients treated by delivering a second embolic agent. Methods, systems, and kits for reducing costs of embolization by at least approximately 18% are described.

摘要： A variety of K-wires with imbedded plates are disclosed that allow for the plate in K-wire to be secured to the bone after insertion. Further, a donut shaped washer for capturing and securing the K-wire is disclosed. Also, a screw with a channel is disclosed that has a head shaped to capture and secure the K-wire. Finally, embodiments of a slotted washer are disclosed that captures and secures the K-wire.

摘要： A combination drill guide and depth gauge surgical instrument for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes an elongated shaft having a drill guide on an end thereof. The instrument also includes a retractable depth probe that may be used to gauge the depth of the holes drilled by use of the drill guide. A method of using such an instrument is also disclosed.

摘要： The invention is generally related to an intervertebral implant for replacing an intervertebral disc of the human spine. The intervertebral implant includes a first conformable endplate, the first conformable endplate being conformable to a boney vertebral endplate under an anatomical load, a second endplate and a core between the endplates, wherein the first conformable endplate partitions the core from the boney vertebral endplate, whereby the core does not contact the boney vertebral endplate. The invention is also directed to a method of replacing an intervertebral disc. The method includes removing at least a portion of an intervertebral disc to form an intervertebral disc space, implanting a first conformable endplate, into the intervertebral disc space and in contact with a first boney vertebral endplate, the first conformable endplate being conformable to the first boney vertebral endplate under an anatomical load; implanting a second endplate into the intervertebral disc space and in contact with a second boney vertebral endplate; and implanting a core between the first conformable endplate and the second endplate, wherein the first conformable endplate partitions the core from the first boney vertebral endplate, whereby the core does not contact the first boney vertebral endplate.

摘要： An intravascular treatment system including an introducer sheath having an intentional friction zone along a section thereof imposing an intentional friction force on the outer surface of a catheter shaft slidable therein. The friction zone representing a non-straight (e.g., curved or bent) section of the introducer sheath and/or a section of the introducer sheath whose inner wall has a reduced inner diameter (e.g., fused heat shrink material). During intravascular treatment, sufficient axial force may be applied to overcome the imposed intentional friction force and advance the intravascular treatment device in a distal direction to a desired target site in the artery. Once properly positioned, the imposed intentional friction force ensures that the intravascular treatment device is maintained in place.

摘要： A tubular braided implant is provided including a braid that can be delivered as a single layer braid, invert into itself during deployment to form at least two nested sacks and include additional braid material that can fill the innermost sack. The additional braid material can loop or coil like a ribbon and/or invert to form smaller and smaller nested sacks. The braid can have a variable braid angle along its length such that when positioned for delivery, the can have a high braid angle near its distal end and a low braid angle near the proximal end. In addition, or as a replacement for the braid material that fills the innermost sack, the implant can include an embolic coil that can loop within the innermost sack.

摘要： Intrasaccular flow diverter including: an interior fill braid physically inverted over itself forming a proximal inverted end and an opposite free end; and a dome braid disposed distally of and secured to the interior fill braid. Subject to application of an external mechanical force, the dome braid is transitionable between an expanded state and a compressed state. The dome braid has a proximal end with an opening defined therein through which starting at the free end the interior fill braid is passable therethrough exerting a radially outward force on the dome braid. A delivery wire is releasably detachable from the proximal inverted end of the interior fill braid. The dome braid has a stiffer profile relative to that of the interior fill braid to maintain in position within the aneurysm the dome braid as the interior fill braid is advanced therein.

摘要： A low profile intervertebral implant for implantation in an intervertebral disc space between adjacent vertebral bodies of a quadruped. The intervertebral implant includes a plate and a spacer that extends from the plate. The intervertebral implant can define geometries that nest with complementary geometries of the vertebral bodies. Further, the plate can include fixation holes that extend along trajectories such that screws inserted through the fixation holes and driven into the respective vertebral bodies can purchase with dense cortical bone.

摘要： A braided implant is provided that can secure within an aneurysm sac, occlude a majority of the aneurysm's neck, and at least partially fill the aneurysm sac. The implant can include a tubular braid that can be set into a predetermined shape, compressed for delivery through a microcatheter, and implanted in at least one implanted position. In some examples, the tubular braid can be implanted in two distinct implanted shapes, allowing for treatment of a wide range of aneurysm sizes. In some examples, the implanted braid can include a compaction resistant column spanning the height of the aneurysm.

摘要： An expandable implant system is configured to increase the height of a target bone, for instance that has been subjected to a compression fracture. The expandable implant system includes an implant assembly that can be inserted into the target bone, and subsequently expanded so as to increase the height of the target bone. The expandable implant system further includes an and insertion assembly that is configured to create an insertion channel into the target bone, such that the implant assembly can be inserted in a collapsed configuration into the target bone along the insertion channel, and subsequently expanded.
