International Classification:

A61F 2/44

US Classification:

623 1711, 606 90, 606 99

Abstract:

An expandable medical implant for supporting skeletal structures. The medical implant having a length along its expandable dimension. The implant having a first tubular member with a connection end, an opposite skeletal interface end, and a central expansion instrument opening. Also, the implant has a second tubular member with a connection end configured to engage with the connection end of the first tubular member. The second tubular member having an opposite skeletal interface end. Additionally, an expansion instrument is insertable through the central expansion instrument opening and expandable against the first tubular member and the connection end of the second tubular member to expand the medical implant. The combined first and second tubular members are of a greater dimension along the length of the implant than the combined first and second tubular members are in any dimension perpendicular to their length.

Assignee:

Warsaw Orthopedic - Warsaw IN

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

Implants sized to be inserted into an intervertebral space between first and second vertebral members. The implants may include a body with opposing first and second ends. An end cap may be connected to the body and include a first side with a contact surface that faces away from the body and is configured to contact against one of the first and second vertebral members when the implant is positioned in the intervertebral space. The end cap may also include a second side that faces towards the body. A connection mechanism may connect the end cap and the body for the end cap to pivot to adjust an angular position of the end cap relative to the body. The body and the end cap may each include locking features that engage together to lock an angular position of the end cap. The locking features may be configured to overlap at each of the angular positions to engage together and maintain the angular position of the end cap relative to the body when the implant is positioned in the intervertebral space.

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An expandable medical implant for supporting bone structures is disclosed. The implant may include an outer member and an inner member receivable in the outer member. One of the outer and inner members includes a tapered surface and the other of the outer and inner members includes a scalloped surface. The implant may also include a locking element disposed between the tapered surface and the scalloped surface. The tapered surface may be movable relative to the locking element to transversely shift the locking element into engagement with the scalloped surface to inhibit a decrease in the overall implant height.

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An expandable medical implant for supporting bone structures includes a curved outer member to cooperatively engage a first bone structure and a curved inner member configured to cooperatively engage a second bone structure. The curved inner member is receivable within and movable relative to the curved outer member along an arc bounded by the curvature of the curved outer member. One of the curved outer and inner members may include a tapered surface and the other of the curved outer and inner members may include a scalloped surface. The implant may include a locking element disposed between the tapered and scalloped surface. The locking element is movable between a locked position engaging the tapered surface and a roughened locking surface to inhibit a decrease in the overall height of the implant and an unlocked position permitting at least an increase in the overall height of the implant.
