Pressurized Cement Placement Patents (Class 606/94)
  • Patent number: 10278754
    Abstract: Systems and methods for treating bone, such as vertebral compression fractures are disclosed. A method includes controllably applying energy to a bone cement volume outside of a patient's body to selectively accelerate the polymerization rate of the bone fill material volume prior to introduction into a bone. The method further includes sequentially introducing a plurality of cement carrying structures with the accelerated polymerization rate bone cement volume into the bone. A system for use in the method includes at least one elongated cement-carrying structure sized to carry a bone cement volume therein and an energy source operatively coupleable to the cement-carrying structure. The energy source applies energy to the bone cement volume to selectively accelerate a polymerization rate thereof. An elongated injector insertable into the bone has a passageway that removably receives the elongated cement-carrying structure to allow delivery of the accelerated polymerization rate bone cement into the bone.

  • Patent number: 10172659
    Abstract: The present invention relates in certain embodiments to medical devices for treating vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the flow of bone cement into the interior of a vertebra and the application of forces causes by the cement flow. An exemplary system utilizes Rf energy in combination a conductive bone cement for selectively polymerizing the inflow plume to increase the viscosity of the cement. In one aspect of the invention, the system utilizes a controller to control bone cement flow parameters to either allow or disallow cement interdigitation into cancellous bone. A method of the invention includes pulsing the flows of bone cement wherein high acceleration of the flow pulses can apply expansion forces across the surface of the cement plume to reduce a vertebral fracture.

  • Patent number: 10117696
    Abstract: A cement-directing structure for use in cement-injection bone therapy includes a collapsible, self-restoring braided structure with regions of differential permeability to the bone cement. The regions of differential permeability may be provided by areas where the braided mesh density is greater or lesser than surrounding areas and/or by means of a baffle. After the structure is placed in a void within a bony structure, cement is injected into the interior of the structure then oozes out in preferred directions according to the locations of the regions of differential permeability.

  • Patent number: 9717544
    Abstract: The embodiments provide devices and methods that both strengthen the bone and stimulate the bone. Bone fractures or non-unions are stabilized, integrated or healed, which results in reduction of a bone defect, such as a bone marrow lesion or edema. In addition, the distribution of forces in a joint are restored or altered to relieve pain. In general, a joint is evaluated by taking an image of the joint and one or more subchondral defects are detected. At least one of the subchondral defects may be diagnosed as the source of pain and an extent of treatment for the subchondral defect is determined. The disclosed devices and techniques are particularly suited for treating chronic defects or injuries, where the patient's natural healing response has not resolved the defect. The present disclosure also provides several exemplary treatment modalities for the different extents of treatment needed.

  • Patent number: 9532884
    Abstract: A laterally deflectable asymmetric implant for implanting into a body may comprise a deflectable piece having distal and proximal ends and assuming a straightened insertion state. The backbone may abut or interconnect with said deflectable piece at the distal end of the deflectable piece. In a fully deflected state the implant may define an asymmetric shape, e.g. a D-shaped loop, defining an at least partially enclosed volume. The deflectable piece may comprise a sequence of segments interconnected at effective hinges. Longitudinal pressure applied to the proximal end of the deflectable piece (or applied to the backbone in an opposite direction) may cause relative longitudinal movement between the backbone and the proximal end of the deflectable piece and may generate outward horizontal movement of the deflectable piece away from the backbone. In one embodiment, the implant is implanted using lateral access into an anterior zone of a vertebra and deployed posteriorly.

  • Patent number: 9005210
    Abstract: The present invention relates in certain embodiments to medical devices for treating vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the flow of bone cement into the interior of a vertebra and the application of forces causes by the cement flow. An exemplary system utilizes Rf energy in combination a conductive bone cement for selectively polymerizing the inflow plume to increase the viscosity of the cement. In one aspect of the invention, the system utilizes a controller to control bone cement flow parameters to either allow or disallow cement interdigitation into cancellous bone. A method of the invention includes pulsing the flows of bone cement wherein high acceleration of the flow pulses can apply expansion forces across the surface of the cement plume to reduce a vertebral fracture.

  • Patent number: 8974465
    Abstract: In at least one embodiment of the present invention, a device for mixing and dispensing a bone cement mixture is provided. The device comprises a first chamber and a second chamber. The first chamber is for containing a first bone cement component. The second chamber is for containing a second bone cement component. A valve is in fluid communication with the first and second chambers. A first and a second plunger are respectively within the first and second chambers and are configured to actuate within their respective chambers. When the valve is in a first position actuating the first plunger advances the first bone cement component into the second chamber to form the bone cement mixture.

  • Patent number: 8968323
    Abstract: A syringe that has a barrel with curvature is provided. The curvature enables a greater volume of bone graft materials to be housed than in a straight syringe without increasing the absolute distance from the handle of the plunger to dispensing end of the syringe. Additionally by maintaining a constant diameter, the barrel permits bone graft material to be dispersed with reduced likelihood of clogging.
