An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

Expandable spinal implant system and method of using same

Disclosed is a method and system for performing a procedure. The system may include a navigation system to be used to at least assist in the procedure. The system may assist in delineating objects and/or determining physical characteristics of subject portions. The system may assist in performing and/or a workflow of the procedure.

System and method for performing and evaluating a procedure

A spinal implant comprises an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an outer surface that defines an oblique surface. A wall is connectable with the implant body and translatable relative to the oblique surface. Systems and methods are disclosed.

Spinal implant system and method

A retention system includes a first member having an inner surface defining a first thread form. The first thread form includes a first stage having a first pitch and a second stage having a second pitch that is greater than the first pitch. A second member includes a shaft and a neck. The shaft includes an outer surface defining a second thread form configured to engage the first thread form to lock the second member with the first member. The neck includes a smooth unthreaded section. Methods of use are disclosed.

Retention system and method

Spinal implant

Surgical implant

A spinal implant comprises a first member, a second member and an actuator defining a transverse pivot axis. A first link is connected to the first member and the actuator adjacent the pivot axis. The first link includes an inner surface defining a cavity. A second link is connected to the second member and the actuator adjacent the pivot axis. The actuator is rotatable for translating the pivot axis such that the second link is movable within the cavity to move the members between a contracted configuration and an expanded configuration. Systems and methods of use are disclosed.

An expandable spinal implant is provided having a frame with a distal wall for retaining an expansion plug such that bone growth promoting material may be introduced to a proximal portion of the implant after expansion. Various implants, systems and methods are disclosed.

Expandable spinal implant system and method

Implantable medical devices are provided. In one embodiment, a device includes a body having an external surface defining an outer profile of the device. The body includes a porous matrix including a series of interconnected macropores defined by a plurality of interconnected struts each including a hollow interior. A filler material substantially fills at least a portion of the series of interconnected macropores. The external surface of the body includes a plurality of openings communicating with the hollow interior of at least a portion of the plurality of interconnected struts. In a further aspect of this embodiment, the external surface includes exposed areas of the filler material and porous matrix in addition to the exposed openings. In another aspect, the porous matrix is formed from a bioresorbable ceramic and the filler material is a biologically stable polymeric material. Still, other aspects related to this and other embodiments are also disclosed.

Implantable medical devices

A surgical injection device includes at least one tubular element defining a passageway. The passageway is configured for disposal of a selected volume of an agent and an evacuator disposed within the passageway. An actuator is engageable with the evacuator to entirely expel the selected volume of the agent from the passageway to a selected site. Spinal constructs, implants, systems and methods are disclosed.

Surgical injection system and method

An expandable interbody implant adapted for insertion at least into a disc space, between two adjacent vertebrae of a spine. An upper member and a lower member are pivotally connected at least by a drive link. A bone graft storage portion packed with a selected volume of bone growth material. A translational wall is provided between the bone graft storage portion and a trailing end of the implant. An actuator engages the bone graft storage portion, pushing it forward into engagement with the drive link, which pivots upward, moving the upper member upward away from the lower member. Upward movement of the upper member raises the translational wall to a position to assist in retention of the selected volume bone graft material within the hollow portion of the bone graft storage portion. Upward rotation of the drive link brings a face thereof into contact with a front of the bone graft storage portion, thereby retaining near constant volume of the bone graft material.

Expandable interbody implant

Spinal implant inserter

Expandable spinal implant system with a biased tip and method of using same

A surgical retractor includes a first member defining a longitudinal axis. The first member includes a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface. A second member has a blade disposed in spaced apart relation relative to the longitudinal axis and a grip surface. The grip surfaces are configured to be drawn together along the longitudinal axis such that the blades are engageable with tissue and connected with the grip surfaces such that the grip surfaces provide a tactile feedback of the tissue engagement. Systems and methods of use are disclosed.

Surgical retractor and method of use

A spinal fusion implant includes a leading end, an opposite trailing end, an upper portion extending between the leading and trailing ends, a lower portion extending between the leading and trailing ends, and opposed first and second side portions extending between the leading and trailing ends. The upper portion includes at least two rails extending between the leading and trailing ends, the at least two rails including a first rail and a second rail spaced apart from one another, the first rail of the upper portion including a bone-contacting surface being at least partially smoothened. The lower portion includes at least two rails extending between the leading and trailing ends, the at least two rails including a first rail and a second rail spaced apart from one another, the first rail of the lower portion including a bone-contacting surface being at least partially smoothened.
