Abstract:
A device (30) for promoting fusion of first and second vertebrae, comprises a first solid region formed of non-porous polyetheretherketone (PEEK) (46) and a first porous region (48, 50) including a porous PEEK architecture. The first porous region is bonded to the first solid region.
Abstract:
Methods and devices for connecting an insertion device (30) to an implant (20). The insertion device includes a body (33) having first and second ends (31,32). The first end may be configured to connect with the implant. The first end may be selectively positionable between orientations to provide for the connection. Methods of positioning the implant within the patient generally include connecting the insertion device to the implant. The insertion device can then be manipulating to position the implant within the patient. The insertion device is removed from the implant once positioned, or may be reconnected at another location to further position the implant.
Abstract:
The application is directed to implants that are adjustable between collapsed and expanded orientations. The collapsed orientation includes a smaller height to facilitate insertion into the patient. The expanded orientation includes a larger height for spacing and/or supporting the vertebral members. The implants (10) generally include three or more separate sections (20,30,40) that are nested together in the collapsed orientation. The sections move outward away from each other in the expanded orientation. An expansion means may be operatively connected to one or more of the sections to move the implants between the orientations. Methods of use are also included for moving the implants between the collapsed and expanded orientations.
Abstract:
The present application discloses intervertebral implants and methods of using the implants. The implants may include inferior (14) and superior surfaces (14), and a sidewall (18) that together form the body (12) of the implant. One or both of the inferior and superior surfaces may include tapered surfaces (30, 32, 34) to facilitate distraction of adjacent vertebral members. The multiple tapered sections allows insertion via multiple surgical approaches using a single implant thereby negating the need to employ a plurality of approach-specific implants as is conventional.

Abstract:
Abstract Devices and methods for inserting an implant within a patient. The device may generally include an insertion body, a supply reservoir, and a delivery device. The insertion body can be used for moving and positioning the implant within the body. In one embodiment, implant is mounted to the end of the body prior to movement and positioning. Fill material is maintained within the supply reservoir. Delivery device functions to move the fill material from the supply reservoir, through the insertion body, and to the implant. The device thus provides for both movement and placement of the implant, and a mechanism for delivering fill material to the implant.
Abstract:
Devices and methods for inserting an implant (90) within a patient. The device may generally include an insertion body (20) , a supply reservoir (30) , and a delivery device (40) . The insertion body can be used for moving and positioning the implant within the body. In one embodiment, implant is mounted to the end (21) of the insertion body prior to movement and positioning. Fill material is maintained within the supply reservoir. Delivery device functions to move the fill material from the supply reservoir, through the insertion body, and to the implant. The device thus provides for both movement and placement of the implant, and a mechanism for delivering fill material to the implant.
Abstract:
The present application is directed to self-locking surgical fasteners. The fastener generally includes a shaft section, a head section, and one or more locking members. The locking members may be located within the head section. A first portion of the locking members may extend beyond an outer surface of the head section, and a second portion of the locking members may extend into a hollow interior of the head section. A tool used to insert the fastener into the patient engages a receiver portion of the fastener. As the insertion tool engages the receiver, the tool may contact and exert a force on the locking member such that the first portion of the locking member may be retracted within the head section. Upon disengaging the insertion tool from the receiver, the locking member may return to the position extending outward beyond the outer surface of the head section.
Abstract:
A faceplate (104) for at least partially covering a plurality of anchor member apertures (126) in an implantable member includes a main body (128) sized to at least partially overlap the plurality of anchor member apertures of the implantable member and configured to inhibit anchor member (106) back-out from the plurality of anchor member apertures. A locking tab may be associated with the main body, the locking tab (130) being formed to at least partially elastically deform to engage the implantable member and secure the main body in place.
