Embodiments of an implant for use in surgery are disclosed. The implant may include elastic polymer file made from a suitable biologically compatible polymer. The implant may also include a reinforcement element.

A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.

A biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

A system, device/implant, method and processes for manufacturing a filament and an implant having at least one or a plurality of areas in the implant comprised of selectively-place bone to facilitate osteoconductivity and, potentially, osteoinductivity after the implant is implanted into a patient.

An implantable composition, method of making and using the implantable composition is provided. The implantable composition comprising a first set of fibers and a second set of fibers, the first set of fibers manufactured to have a first binding surface, the second set of fibers manufactured to have a second binding surface, the first binding surface of the first set of fibers configured to bind at least at or near the second binding surface of the second set of fibers and the second set of fibers configured to bind at least at or near the first binding surface of the first set of fibers.

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectional areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Synthetic composite materials for use, for example, as orthopedic implants are described herein. In one example, a composite material for use as a scaffold includes a thermoplastic polymer forming a porous matrix that has continuous porosity and a plurality of pores. The porosity and the size of the pores are selectively formed during synthesis of the composite material. The example composite material also includes a plurality of a anisometric calcium phosphate particles integrally formed, embedded in, or exposed on a surface of the porous matrix. The calcium phosphate particles provide one or more of reinforcement, bioactivity, or bioresorption.

Implantable devices for orthopedic, including spine and other uses are formed of porous reinforced polymer scaffolds. Scaffolds include a thermoplastic polymer forming a porous matrix that has continuously interconnected pores. The porosity and the size of the pores within the scaffold are selectively formed during synthesis of the composite material, and the composite material includes a plurality of reinforcement particles integrally formed within and embedded in the matrix and exposed on the pore surfaces. The reinforcement particles provide one or more of reinforcement, bioactivity, or bioresorption.

A mosaic implant (2010) comprises a mesh support frame comprising a plurality of polygonal support rings (2040 A, B, C) connected by a plurality of struts (2014), and a plurality of mosaic plates (2012). The support rings are positioned within the mosaic plates; the struts extend between adjacent plates. An implant (1510) for filling a bore hole comprises a plate (1512) and a support frame (1520) having a central portion (1522) located at least partially within the plate, a polygonal outer rim (1524) having a plurality of fastening points for attaching the implant to bone surrounding a bore hole, and a plurality of arms (1530) extending between the central portion and the outer rim. The plurality of arms extend inwardly and downwardly away from the outer rim such that the central portion is located below the plane of the outer rim and the upper surface of the plate is flush with or slightly above the upper surface of the outer rim.

An intervertebral implantation system for restoring disc height and vertebral alignment, while allowing dynamic mobility and stabilization of the vertebral segment, and minimally invasive methods of implanting the same. The implantation system includes an annular reinforcement implant, including an elastomeric balloon inserted into the hollow or interior of a tubular sleeve, and secured only at a first and second neck portions to a securement element coupled to an attachment fixture, forming an annular structure attached to the outer margin of the annulus fibrosus. When the prosthetic implant is in a contracted state the tubular sleeve is redundant and undulated, forming folds, gathered loosely around the circumference of the inner balloon. Upon pressurized inflation with in-situ curable polymer, the elastomeric balloon elongates and expands circumferentially, and the tubular sleeve stretches and unfolds, constraining further expansion and elongation of the elastomeric balloon. The attachment fixture is configured to provide secure attachment to the outer margin of the annulus fibrosus. A temporary, high pressure vertebral distraction balloon is utilized to aid in vertebral distraction during a surgical procedure to implant the annular reinforcement implant.
