  • FOLDED ANEURYSM TREATMENT DEVICE AND DELIVERY METHOD
    Publication number: 20210196284
    Abstract: A method of occluding an aneurysm includes positioning a braided implant within an aneurysm sack such that an outer non-inverted layer contacts a wall of the aneurysm and an inverted layer apposes the outer non-inverted layer to form a double layer of braid across a neck of the aneurysm. A radiopaque end of the braided implant can be positioned centrally within the aneurysm so that the radiopaque end extends adjacent or across a plane defined by a fold between the outer non-inverted layer and the inner inverted layer. Embolic coils can be inserted into the aneurysm sac and inhibited from exiting the aneurysm at the neck by the double layer braid across the aneurysm neck.

  • SYSTEMS AND METHODS FOR EMBOLIC IMPLANT DETACHMENT
    Publication number: 20210196281
    Abstract: An aneurysm treatment system can include an embolic implant, a delivery system, and an introducer sheath that are collectively designed so that the combination of the introducer sheath and the delivery system can be used as a deployment apparatus for the embolic implant. The introducer sheath can be moved proximally against an interference feature attached to a pull wire to cause the interference feature to separate from the delivery tube, thereby pulling the pull wire and releasing the implant. Alternatively, the treatment system can include an embolic implant and a delivery system that includes a delivery tube, a proximal extension, a pull wire attached to the proximal extension, and a disconnection feature that can be broken to allow the proximal extension and the pull wire to be translated proximally in relation to the delivery tube.

  • Alignment guide
    Patent number: 11045323
    Abstract: An orthopaedic joint prosthesis assembly includes a head part of an orthopaedic joint prosthesis component and an alignment guide. The head part has a spherical hearing surface for articulation with a corresponding joint surface, and an assembly surface having a first bore formed in it for receiving a spigot on another part of the orthopaedic joint prosthesis. The bore has a first axis that extends perpendicular to the assembly surface. The alignment guide has an axial portion defining a second axis and an arm extending from the axial portion. The arm includes a distal portion which is configured to engage the assembly surface, with the axial portion being arranged to engage the bearing surface of the head part when the head part is mounted within the guide such that an impaction force applied along the second axis is directed along the first axis.

  • Flexible spinal driver or drill with a malleable core, and/or fixed core radius
    Patent number: 11045210
    Abstract: The improvement is a spinal instrument (preferably, a bone screw driver) having a flexible shaft comprising a plurality of interlocking segments carried on a malleable core rod. The flexible shaft allows a screwdriver handle to be perfectly in-line with the cage inserter if desired, while still taking advantage of the tactile feel and torque transmission of the flex segment in its bent position. Accordingly, a surgeon can limit the amount of retraction and keep the driver handle close to the inserter without having to overcome the forces of the flexible segments' natural straight configuration.

  • Intervertebral implant inserters and related methods
    Patent number: 11045331
    Abstract: Implant inserters and related methods are disclosed herein, e.g., for delivering a fusion cage or other implant to a spinal disc space and for rotating or articulating the implant within the disc space. An exemplary instrument can include an inner member having opposed jaws for grasping the implant and holding the implant during insertion. The inner member can be slidably received within an outer member such that relative axial translation of the inner and outer members is effective to open or close the jaws. The jaws and/or the distal end of the outer member can have a low-profile geometry, which can advantageously facilitate certain surgical procedures. For example, the low-profile geometry can allow for a more medial approach to an intervertebral disc space in which the implant is to be inserted.
