Apparatus for delivering a quantity of fluid to bone marrow of a bone or providing access to remove fluids from a target site is provided. The apparatus may include a driver, a plunger operating and cartridge assembly mechanism, a cartridge assembly having a fluid reservoir and a bone penetrating needle.

An adjustable suture passer for use in arthroscopic surgery is disclosed. In a preferred embodiment, the adjustable suture passer comprises a head that describes a semicircular arc, an elongate body, a support element, and driving and control mechanisms. The head is adapted to accommodate a surgical needle and a guide wire. When the adjustable suture passer is activated, the needle is driven with sufficient force to penetrate bone. Use of the adjustable suture passer thus enables surgical attachment of soft tissue to bone without any necessity for a separate anchor.

A surgical injection device includes at least one tubular element defining a passageway. The passageway is configured for disposal of a selected volume of an agent and an evacuator disposed within the passageway. An actuator is engageable with the evacuator to entirely expel the selected volume of the agent from the passageway to a selected site. Spinal constructs, implants, systems and methods are disclosed.

The present invention relates to a system, method, device and kit which utilize a modular pedicle screw implant that does not require the use of a guide wire for implantation and can be assembled in situ. The system, method, device, and kit include a surgical instrument for implanting a modular pedicle screw comprising a cannula coaxially aligned with a modified trocar style instrument or surgical shaft. The surgical shaft contains a first member of a surgical shaft-inner pedicle bone screw member joint, illustrated herein as a locking taper, for securing an inner member of a pedicle screw thereto. The inner member of a pedicle screw is further adapted to couple to an outer pedicle sheath. In combination, the inner member of a pedicle screw and the outer pedicle sheath form a solid modular pedicle screw.

An ultrasound guided puncture device and an ultrasound guided puncture apparatus are disclosed. The ultrasound guided puncture device includes a puncture needle tube and an ultrasound transducer. One end of the puncture needle tube has a puncture needle head, and the ultrasonic transducer is housed in the puncture needle tube and extends to the puncture needle head. The ultrasonic transducer includes multiple ultrasonic array elements for transmitting and receiving ultrasonic waves, and the multiple ultrasonic array elements are arranged at the puncture needle head. In actual use, electronic scanning imaging is performed through the multiple ultrasound array elements, hence a wide imaging range. It can effectively recognize the structure of the tissue in front of the puncture needle head, thereby facilitating the planning of the best puncture path.

A bone harvesting device includes a main body having an internal cavity and a suction port adapted to be coupled to a suction source. The device further includes an outer tube (200) having an interior surface, an exterior surface, a proximal end and a distal end, the proximal end of the outer tube being coupleable to the main body, an inner tube having an interior surface, an exterior surface, a proximal end and a distal end, the inner tube being in fluid communication with the internal cavity and at least partially disposed within the outer tube such that a venting channel is defined between at least a portion of the inner tube and at least a portion of the outer tube.

Described herein are various implementations of systems and methods for accessing and modulating tissue (for example, systems and methods for accessing and ablating nerves or other tissue within or surrounding a vertebral body to treat chronic lower back pain). Assessment of vertebral endplate degeneration or defects (e.g., pre-Modic changes) to facilitate identification of treatment sites and protocols are also provided in several embodiments. Several embodiments comprise the use of biomarkers to confirm or otherwise assess ablation, pain relief, efficacy of treatment, etc. Some embodiments include robotic elements for, as an example, facilitating robotically controlled access, navigation, imaging, and/or treatment.

A flip cutter and drill instrument and method of antegrade drilling and retrograde cutting using such an instrument. The flip cutter and drill instrument is provided with a drill which has a multi-blade configuration and which engages an inner tube or inner member of the instrument to articulate between at least a first “straight” position (for example, about parallel to the longitudinal axis of the instrument) when the instrument is in the drilling mode, and at least a second “flip” position (for example, a non-parallel position relative to the longitudinal axis of the instrument) when the instrument is in the cutting mode.

A fixation system for repairing a pars fracture includes a needle guide configured to be docked on a lamina of the pars, a needle, a guidewire, and a screw assembly. A portion of the needle is configured for insertion through a passage of the needle guide. A portion of the guidewire is configured for insertion through a passage of the needle. The screw assembly includes a collar and an elongated portion, the collar being movable with respect to the elongated portion. A portion of the screw assembly is configured to contact the lamina co-axially with the guidewire.

An apparatus for penetrating bone and accessing bone marrow is provided. The apparatus may include a penetrator assembly and a powered drill. The penetrator assembly may include an inner penetrator having a stylet. The penetrator assembly may also include an outer penetrator having a hollow cannula and a luer lock attachment. The powered drill may include a housing enclosing a motor and a power supply and associated circuitry. The powered drill may also include a connector receptacle for receiving a penetrator assembly connector of the penetrator assembly. The powered drill may include a magnetic connection which releasably locks the penetrator assembly connector into place with the powered drill. The power supply may include a rechargeable battery within the housing for supplying power to the motor. A battery indicator may be provided to indicate a level of the battery.
