Publication number: 20230200856Abstract: A woven retention device that is configured to receive a fastener in a bone hole can be configured to promote bone ingrowth and impede biofilm formation. The woven retention device can be made of woven filaments that outline apertures of varying sizes and shapes and can serve as an interface between the fastener and the bone material. In a first relaxed state, the interwoven filaments can outline apertures of varying sizes and shapes within a predetermined range and in a second constricted state inside the bone hole with the fastener the interwoven filaments can outline apertures of decreased area that still fall within the predetermined range. The woven retention device can be configured to allow for optimal bone growth while at the same time minimizing the likelihood that biofilm forms thereon.Type: ApplicationFiled: July 22, 2022Publication date: June 29, 2023Inventors: Robert LUZZI, Francis Patrick MAGEE

Patent number: 11672579Abstract: 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·s to greater than about 5000 Pa·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.Type: GrantFiled: November 26, 2018Date of Patent: June 13, 2023Assignee: DFine Inc.Inventors: Csaba Truckai, Robert Luzzi, Andrew Kohm, John H.

Patent number: 10278754Abstract: 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.Type: GrantFiled: February 1, 2017Date of Patent: May 7, 2019Assignee: DFine, Inc.Inventors: Csaba Truckai, John Shadduck, Robert Luzzi
