A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

Systems and methods for treating a vertebral body. An intravertebral implant includes an anterior end element and a plate comprising a planar bearing surface. The plate may be exactly two plates movable in only a cranio-caudal expansion plane. A pedicle fixation is coupled to the intravertebral implant and includes a hollow sleeve. The pedicle fixation is configured to be secured to the pedicle to control an insertion depth of the intravertebral implant within the vertebral body. A central traction member is movably disposed within the hollow sleeve of the pedicle fixation to deploy the planar bearing surface(s). The central traction member may be rotatable within the hollow sleeve. An expansion instrument may move the central traction member relative to the pedicle fixation. The intravertebral implant may be locked relative to the pedicle fixation in six degrees of freedom.

An expandable, intervertebral spacer includes a top component and a base component in engagement with the top component, the base component defining at least one channel for receiving a hardening material, and placement of the hardening material within the channel causes the top component to move between a first position in which the top component is a first distance from the base component and a second position in which the top component is a second distance from the base component, the second distance being greater than the first distance. The hardening material can be removed from the channel by a flexible coring tool, and the top component forced toward the base component to collapse the spacer.

Systems and methods for bone cement removal using real-time acoustic feedback, such as during a drilling process in a revision arthroplasty, are discussed. A system for bone cement removal may include a processor to perform operation comprising receiving digital frequency data from the microphone, comparing at least a portion of the digital frequency data to a plurality of frequency signatures, and determining, based at least in part on the comparing, whether the portion of the digital frequency data is representative of a cut bone frequency or a cut bone cement frequency.

Devices and methods for the removal of bone implant tips from within a bony structure in a body. The device or method includes a shaft with an internal grasping feature capable of being inserted while remaining in an un-expanded, un-deployed state. This permits a surgeon or operator to insert the device while in a small profile state, avoiding or reducing damage to adjacent bone tissue during insertion. Upon insertion of the shaft to the proper position within a patient's bone, the grasping feature may then be expanded or deployed from the distal end of the shaft by a surgeon or operator using an actuator in a handle attached to the proximal end of the shaft. Following deployment, the grasping feature may be used to manipulate and/or remove a bone implant tip from a patient's bone tissue. Embodiments of the grasping feature include one or more hooks, wires, articulating fingers, and/or net-based designs formed of metal, polymer, composite, or a combination thereof. The grasping feature may also include an adhesive-based design formed of bone cement, protein-based glue, or other adhesive material with the purpose of grasping or manipulating a bone implant tip within bone tissue.

A gouger grasper device including a handle at a proximal end of the device, the handle having a base and a trigger movably connected to the base, a chisel at a distal end of the device, a jaw at a distal end of the device and movable relative to the chisel, and a ratcheting assembly for moving the jaw relative to the chisel between an open position and a clamping position in response to movement of the trigger relative to the base.

The present disclosure provides a system for injecting a drug eluting construct in a patient. The construct includes multiple cellular based microcaspules, wherein the multiple cellular based microcapsules create at least one of a plurality of layers or sections of microcapsules joined together to comprise an implant. There is a medicinal agent within the microcapsules. A syringe and needle inject the implant constructed of microcapsules into the patient at least one of during and after a surgical procedure. The medicinal agent controllably releases into the patient both immediately and at a delayed time.

The present disclosure provides a method of positioning an implant in a patient. The method includes inserting a deflated biodegradable balloon into a joint of the patient, wherein the biodegradable balloon is wedged between at least one of bone and soft tissue in the joint of the patient. The biodegradable balloon is inflated by injecting a warmed sterile liquid from a syringe through an inlet valve and the inflated biodegradable balloon is at least one of sized and shaped to fit within the surgical field. The expanded biodegradable balloon is a joint spacer, changing the spatial relationship between the bones and soft tissue in the joint of the patient.
