Publication number: 20210121212Abstract: A flexible connecting system consists of a flexible connecting rod manufactured from a rigid material, a leading segment and a trailing segment. The body has at least one flexible center section, each having at least one slot to provide flexibility. The slot follows a sinuous, serpentine path to form a plurality of interlocking teeth that can follow a helical or a concentric path. One or more flexible sleeves are dimensioned to fit over the connecting rod to prevent the ingress or egress of material. One or both of the ends of the flexible connecting rod and flexible sleeve can be open or sealed.Type: ApplicationFiled: January 5, 2021Publication date: April 29, 2021Inventor: William R. Krause

Publication number: 20210121213Abstract: The invention relates to a plate fixed between two bone parts by way of screws engaged in holes formed in the thickness of said plate. The plate comprises an angled member or rib which is inclined according to an angle of between about 30° and 60° in relation to the plane defined by the plate. The angled member or rib has a hole for engaging a screw and is located in the central part of the width, over a determined part of the length of the plate, so that the screw brings the two bone parts into a compressive position.Type: ApplicationFiled: January 7, 2021Publication date: April 29, 2021Applicant: Stryker European Operations Holdings LLCInventors: Bernard Prandi, Keith Wapner, Charles P.

Publication number: 20210121217Abstract: A system for restoring height of a vertebral body with a balloon and stabilizing the vertebral body with bone cement. A delivery tube extends from a handle and may be formed from a flexible polymer and a radiopaque filler. The flexible polymer maintains a patent lumen along a curve so as to receive sequential introduction of the balloon and the bone cement to within the vertebral body at a location offset from a longitudinal axis. The radiopaque filler provides for at least a portion of the delivery tube being radiopaque under fluoroscopic visualization. The radiopaque filler may be barium, and the delivery tube may be constructed from coextruding the flexible polymer with the barium. Visual indicia on the handle may indicate a position of the delivery tube relative to another component of the system such as an access cannula. The visual indicia may indicate a direction of the curve.Type: ApplicationFiled: January 6, 2021Publication date: April 29, 2021Applicant: Stryker CorporationInventors: Evan D. Linderman, John A.
