A medical device for treating hip joint osteoarthritis in a human patient by providing at least one artificial hip joint surface. The medical device comprises a prosthetic part or a bone plug adapted to be placed in a hole in the pelvic bone and a supporting member connected to said prosthetic part or bone plug, wherein the prosthetic part or the bone plug is adapted to be inserted into said hole from the abdominal side of the acetabulum and oriented, during the insertion, such that the concave interior surface is facing in the direction towards the caput femur. Wherein the medical device comprises an artificial caput femur surface or artificial acetabulum surface, and wherein a largest cross-sectional distance of said artificial caput femur or acetabulum surface is smaller than said hole, such that said artificial caput femur surface can pass through said hole.

The invention comprises a system for securing an implant to a bone comprising an implant which is affixed to the bone, a grout or bone cement comprising a composition that cures in an exothermic reaction and which is capable of securing the implant to the bone in a cured state, and a tester which measures temperature over time to detect a rate change of temperature and uses a novel discrete differentiator circuit to determine when the composition reaches cure.

Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.

The present invention relates to a primer composition that may be applied to tissue in order to increase bond strength between the tissue and a patch, filler or a supporting material. The primer comprises a dithiol component and an allyl containing component together with a photo initiator.

Systems and methods for treating vertebral compression fractures are discussed. In an embodiment, a method includes mixing bone cement precursors thereby causing a first chemical curing reaction characterized by a first time-viscosity profile, controllably applying energy to the bone cement from an external source to modify the first time-viscosity profile to a second time-viscosity profile, and injecting the cement into bone at a substantially constant viscosity greater than about 1000 Pa.Math.s to greater than about 5000 Pa.Math.s over an extended working time. In another embodiment, a bone cement injector system is provided that includes a first handle component that is detachably coupled to a second sleeve component having a distal end for positioning in bone and a flow channel extending through the first and second components. The system includes first and second thermal energy emitters for delivering energy to bone cement flows in a flow channel portion in the first and second components, respectively.

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. A device for use in repairing a fractured bone includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of at least one reinforcing material and an inner lumen for passage of a light source; a conformable member releasably engaging the distal end of the delivery catheter, wherein the conformable member moves from a deflated state to an inflated state when the at least one reinforcing material is delivered to the conformable member; and an adapter releasably engaging the proximal end of the delivery catheter for receiving the light source and the at least one reinforcing material.

A spine stabilization device having an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra. The device further includes a fixation device to be inserted after placement of the interbody spacer, the fixation device having a support portion securing the interbody spacer against escaping from between the vertebral bodies into a ventral direction. The support portion rests against a portion of an anterior surface of the interbody spacer, and includes an anchor. The anchor has an anchoring material portion that is inserted, in a liquid state, into cancellous bone tissue of at least one of the vertebral bodies of the upper and lower vertebra, to thereby infiltrate the cancellous bone tissue, and to harden thereafter so as to fix the support portion to the vertebral body.

A cannula device for removing, including by aspirating, bodily material is disclosed. The device may include a cannula and a hub. The cannula includes an open proximal end and a deflectable distal segment, and one or a plurality of distal orifices fluidly connected to the lumen. When distally extended from an outer guide cannula, the deflectable segment assumes a curved shape, which includes temperature-dependent curvature subject to elevated temperature along a memory metal length of the cannula.

The present disclosure relates to bone cement formulations that have an extended working time for use in vertebroplasty procedures and other osteoplasty procedures together with cement injectors that include energy delivery systems for on-demand control of cement viscosity and flow parameters. The bone cement formulations may include a liquid component having at least one monomer and a non-liquid component including polymer particles and benzoyl peroxide (BPO). The non-liquid component may be further configured to allow controlled exposure of the BPO to the liquid monomer so as to enable control of the viscosity of the bone cement composition.
