International Classification:

A61B 17/70
A61B 17/88

US Classification:

606264, 606279

Abstract:

An anchor-in-anchor fixation system is provided for securing underlying structure, such as bone. The fixation system includes a first bone anchor having a shaft for fixation to underlying bone, and a head that defines an internal bore. A second bone anchor extends through the bore and into underlying bone. A fixation assembly is also provided that includes one or more fixation systems coupled to an auxiliary attachment member configured for long bone fixation, spinal fixation, or fixation of other bones as desired.

International Classification:

A61B 17/70
A61F 2/44

US Classification:

606264, 623 1711

Abstract:

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Inventors:

Lawton Laurence - West Chester PA, US

International Classification:

A61F 2/44
A61B 17/56

US Classification:

623 1716, 606 86 A

Abstract:

A flexible implant system for positioning a flexible spacer between adjacent vertebrae including and interbody spacer and an insertion instrument. The interbody spacer including a central axis, a lateral axis, a top surface positioned generally parallel to the central axis and a plurality of hinge sections extending generally perpendicular to the central axis. A plurality of notches making up the plurality of hinge sections adjacent the top surface that permit the interbody spacer to flex. The interbody spacer further including a groove extending along a lateral side surface, generally parallel to the central axis. An insertion instrument includes a proximal end, a distal end and a tongue extending from the proximal end to the distal end along a non-linear path. The groove slidably engages the tongue to guide the interbody spacer from the proximal end to the distal end along the non-linear path.

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An intervertebral implant () for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion (), a plate portion () operatively coupled to the spacer portion and one or more blades () for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins () for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral transposals approach. Alternatively, the implant may be configured for insertion via an anterior approach.
