Disclosed herein is a bone cage that includes a shaft extending from a head to a tapered tip and including threads disposed on an external surface of the shaft. The cage also includes a plurality of fenestrations defining a row disposed in at least a first helix along at least a portion of the shaft, each of the plurality of fenestrations extend directly through a natural portion of the thread. The cage also includes a cannula positioned within the shaft and extending from an opening in the head to another opening in the tip. Each of the fenestrations are defined by a wall that extends from the exterior of the shaft to the cannula.

A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

A flexible body comprises a polymer film having a first surface and an opposing second surface. The polymer film has a plurality of apertures extending from the first surface to the second surface and a plurality of raised lips protruding from the first surface such that each of the plurality of apertures is surrounded by one of the plurality of raised lips. A method of producing a polymer film comprises placing a polymer solution into a one sided mold having a plurality of protrusions extending from a bottom of the mold wherein the polymer solution is characterized by a viscosity that inhibits the unaided flow of the polymer throughout the mold; urging the polymer solution around each of the plurality of protrusions; and solidifying the polymer solution.

This disclosure is directed to a resilient interpositional arthroplasty implant. Such implants function to pad cartilage defects, cushion, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. The walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability so as to enable immediate limb use after outpatient surgery. Appendages of the implant may repair or reconstruct tendons or ligaments, and menisci by interpositional inflatable or compliant polymer arthroplasties that promote anatomic joint motion.

Disposable temporary spacer device for an articulation of the human body or for a bone cavity, wherein the spacer device includes at least one first component adapted to be constrained to a bone portion or end, wherein the spacer device is made from a biologically compatible material and comprises interconnected pores distributed in the entire volume occupied by the spacer device, in which the interconnected pores have a size and occupy a percentage of the volume of the spacer device such that it is able to absorb and consequently elute one or more pharmaceutical or medical substances in liquid or fluid form or in paste, cream, gel, wax, or viscous form.

The present application discloses embodiments related to an implant and a method of forming an implant configured to treat a fractured bone. The implant can include a body having a proximal end, a distal end, and an outer surface extending from the proximal end to the distal end, wherein the body defines a central axis extending from the proximal end to the distal end; and a high tensile strand positioned adjacent the body such that at least a portion of the strand extends at least partially along the outer surface of the body in a direction substantially parallel with the central axis, and wherein the strand is loaded with an active agent.

A delivery device for delivering substance to bone includes a luer portion configured to be detachably coupled to a bit driver, the luer portion having a luer thread. A bit portion is rigidly coupled the luer portion, and the bit portion is configured to accommodate the bit driver. A fluted portion is rigidly coupled to the bit portion, the fluted portion comprising a flute, the flute configured to create a hole in the bone. A conduit extends through the luer portion and the bit portion, at least partially through the fluted portion. The flute defines an aperture extending from the conduit entirely through the flute, and the aperture is configured to allow a substance to pass therethrough.

An implant having a porous portion with a plurality of interconnected voids for receiving at least one injectable substance such that an injectable substance can elute from the porous portion. A syringe can be inserted into the at least one porous portion for administering the at least one injectable substance into the voids of the porous structure. The implant can be implanted with the at least one porous portion pre-loaded with the at least one injectable substance. The at least one porous portion can be loaded by inserting the syringe into the at least one porous portion after implanting the implant. The porous portion can be re-loaded with the syringe after the at least one injectable substance has eluted from the porous portion or replaced with a different injectable substance.

Implantable fasteners that can be repositioned after implantation, and implants including these repositionable implantable fasteners, have been developed. The fasteners are designed to fixate medical devices and other implantable components in the body, and can be adjusted after initial fixation in tissue to reposition the implanted medical device. The fasteners include a plurality of tissue retainers emanating from a supportive backing, wherein the tissue retainers can swivel from the plane of the supportive backing to engage tissue. The fasteners are fixated in tissue by movement in a first direction, and can be removed when pulled in a direction opposite to the first direction. The fasteners may be attached to medical devices before or after implantation. In one embodiment, the implant is a mastopexy device in the form of a mesh and the repositionable fastener.
