Abstract: An implant device configured to be at least partially in contact with bone on implantation and having an improved osteoinductive feature to enhance new bone formation. The implant device has one or more bone growth surfaces extending from a structurally solid feature of the implant device. The one or more bone growth surfaces are configured to mimic adult trabecular bone by having recesses and prominences. The recesses extend 10 to 500 microns in depth and may have an increasing inclination from the surface extending inwardly and not parallel to opposing or adjacent walls. The one or more bone growth surfaces form a random and/or non-random network.

Abstract: An implant device configured to be at least partially in contact with bone on implantation has an improved osteoinductive feature to enhance new bone formation. The implant device has one or more bone growth surfaces extending from a structurally solid feature of the implant device. The one or more bone growth surfaces are configured to mimic adult trabecular bone by having trenches, grooves or surface recesses or prominences exhibiting numerous structural elements or walls not perpendicular to the surface that are non-coplanar or arched extending 20 to 500 microns in depth having an increasing inclination from the surface extending inwardly and not parallel to opposing or adjacent walls forming a random or non-random network. The one or more bone growth surfaces configured to mimic trabecular bone have discernable nano features on the structural elements or walls exhibiting nano scale features of less than 200 nano meters within the network.

Abstract: An expandable, adjustable inter-body fusion device is presented. The inter-body fusion device can have a first plate, a second plate, and an insert positioned substantially therebetween the first plate and the second plate. The first plate, the second plate, and the insert define an interior cavity. Moving the insert longitudinally with respect to the first and second plates increases or decreases the distance of the first plate with respect to the second plate, effectively expanding the inter-body fusion device and increasing the volume of the interior cavity. The angle between the first plate and the second plate is selectively adjustable.

Abstract: A surgical drain system for use during and following surgery is provided. A collection reservoir is placed in fluid communication with the body of a user through a collection port. A pump creates a vacuum pressure to urge fluid into the collection reservoir. Fluid exits the collection reservoir through a drain port. A drain mechanism allows air to come into the collection reservoir through an air intake aperture and collected fluid to leave the reservoir simultaneously. The drain system can be worn beneath clothes.

Abstract: An expandable assembly for insertion into an intervertebral space is presented. The assembly, in particular aspects, includes an elongate body comprising an upper portion and a lower portion. The assembly may include an expander that is sized and shaped for insertion between the upper portion and lower portion, thereby selectively expanding the upper portion away from the lower portion. The elongate body may also include one or more bone graft windows.

Abstract: A portal for accessing a desired lamina portion of a desired cervical vertebra to perform a laminoplasty. In one aspect, a laminoplasty portal is presented that defines an interior conduit and has a first sidewall section and a second sidewall section.

Abstract: An implantable device and method for fixation of spinous processes is presented. The device has first and second spaced plates, the first plate having a surface facing a surface of the second plate. The plates are configured for placement on either side of two adjacent spinous processes. The plates are held in place adjacent each side of the two spinous processes by a post connected to each of the plates and extending substantially therefrom the facing surface of the first plate to at least the facing surface of the second plate.

Abstract: An expandable vertebral body replacement is presented. The device has an inner and outer wall longitudinally moveable on one-another which locks in place using a ratchet mechanism. This can be locked or fortified by several described options. Also presented is a method for expanding said device embodiments.
