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&#xb7;s to greater than about 5000 Pa&#xb7;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.

Bone treatment systems and methods

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.

Retention devices, lattices and related systems and methods

Surgical devices, systems and methods for treating tissue are provided. Also provided are systems for treating tissue and methods of treating tissue. An exemplary surgical device comprises a handle () having a proximal end and a distal end; a shaft extending distally beyond the distal end of the handle, the shaft having a proximal end and a distal end; an electrode tip (), at least a portion of the electrode tip extending distally beyond the distal end of the shaft, the electrode tip extending distally beyond the distal end of the shaft comprising a spherical end surface portion () and a cylindrical side surface portion, the spherical end surface portion located distal to the cylindrical side surface portion and comprising at least a portion of the distal end surface of the surgical device; and a fluid passage directed to provide a fluid towards the cylindrical side portion of the electrode tip.

Fluid-assisted medical devices, systems and methods

A soft tapping device for preparing a bone hole that includes a substantially cylindrical insert that is sized to enter into a compressed woven retention device. The substantially cylindrical insert has protrusions that are adaptable to expand portions of a compressed woven retention device inside the bone hole. The substantially cylindrical insert is also configured to exit from the compressed woven retention device without changing the expanded portions of the compressed woven retention device.

Tapping devices, systems and methods for use in bone tissue

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.

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.

An electrosurgical device includes a first electrode tip connected to a first shaft and spaced from a second electrode tip connected to a second shaft. The first electrode tip serves as a first pole, and the second electrode tip serves as a second pole, of a bipolar electrode configuration. A first fluid outlet opening is defined by a distal end of the first shaft and a portion of the first electrode tip. A second fluid outlet opening is defined by a distal end of the second shaft and a portion of the second electrode tip. At least one recess can be formed in an exterior surface of each of the first and the second electrode tips, providing a fluid flow channel for fluid to flow distally along the respective electrode tip.

Surgical devices for treating tissue are provided. Also provided are systems for treating tissue and methods of treating tissue. An exemplary surgical device has a handle, a fluid passage connectable to a fluid source, a tip portion and a distal end. The tip portion can simultaneously provide RF power and conductive fluid to tissue. The tip portion includes an electrode having a domed portion having a domed surface and a cylindrical portion having a cylindrical surface. The domed portion is located distal to the cylindrical portion and occupies at least a portion of the distal end of the surgical device. The device includes a fluid outlet opening in fluid communication with the fluid passage, the fluid outlet opening configured to provide the conductive fluid to a surface of the electrode proximal to the distal end surface of the surgical device.

Systems and methods for delivering bone cement into a bone can include a handle body defining a flow path, a thermal emitter in the handle body to apply energy to bone cement passing through the flow path, a source of bone cement and an injection cannula. The cannula can be in communication with the flow path such that inserting the cannula into a bone can allow a flow of bone cement therethrough to an opening at a distal end of the cannula. Other systems and methods for delivering bone cement into a bone can include an injector body with a handle portion, and a cannula, a bone cement container, a low pressure drive mechanism configured to effect a flow of bone cement from said container to the injector body and a high pressure drive mechanism configured to effect a flow of bone cement through the injector body into the bone.
