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.

Devices and methods used to obtain core tissue samples are disclosed. The devices may be configured to drill into cortical bone and saw a hole into a bone lesion and/or bone marrow while obtaining the core tissue sample. The devices can include a motor and a transmission configured to rotate a trocar having a tip configured for drilling and an outer coax cannula having a cutting tip configured for sawing. The core tissue sample may be received within an inner cannula. A part-off tab may cut or sever the core tissue sample from the bone lesion and/or bone marrow.

An improved cannulated aspiration screw device and method of use thereof for removal of, inter alia, bone marrow from a patient's bone. The cannulated aspiration screw device includes a shaft at its proximate end and a drilling dip section at its distal end and has a removable insert, that when inserted in the cannulated aspiration screw device at is proximate end prevents the flow of materials into and through the cannulated aspiration screw device while the device is being screwed into the bone. Once the cannulated aspiration screw device is screwed in place, the removable insert is removed, and an aspiration device (such as a surgical syringe) is then connected at the proximate end of the cannulated aspiration screw device (generally utilizing a connector) and aspiration is then performed using the aspiration device.

A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.

Assistive apparatuses or devices, kits, and methods for assisting with removal of a biological sample from an intraosseous device are described. Some of the present assistive apparatuses comprise: a body including a first end and a second end, and defining a channel with a first portion having a first transverse dimension, a second portion disposed between the first portion and the second end and having a second transverse dimension that is smaller than the first transvers dimension, and a longitudinal axis extending through the first portion and the second portion, the body further including a protrusion extending laterally outward relative to the longitudinal axis; where the channel is configured to receive a portion of an intraosseous device having a hub and a cannula extending from the hub, with the first portion of the channel receiving a part of the hub, and the second portion of the channel receiving a part of the cannula while preventing passage of the hub through the second portion.

A bone harvester and bone marrow removal system. The bone harvester can include a body defining a channel extending longitudinally therethrough from a distal to a proximal portion of the body. The distal portion can include a cutting tip. Bone marrow may be drawn through the channel.

A handle device is provided comprising a first wing and a second wing. The first wing and the second wing are configured to pivot about a common axis to one another. The first wing has one or more first ridge, and a first one or more clearance spaces. The second wing has one or more second ridges and a second one or more clearance spaces. The one or more first ridges is configured to be received within the second one or more clearance spaces and the one or more second ridges is configured to be received within the first one or more clearance spaces when the first wing is pivoted about the common axis to the second wing in a folded configuration.

A medical compound preparation and delivery system, including a delivery device, the device including a depressible trigger operably coupled to move a plunger; a cartridge releasably coupled to the delivery device, the cartridge defining a lumen therethrough to receive at least a portion of the plunger therein; a receptacle defining a cavity therein for receiving a medical compound; a first tube slidably positionable within the cavity of the receptacle; and a second tube slidably positionable within the first tube, wherein the cartridge is slidably positionable within the second tube.

An intraosseous device, comprising a cannula through which life-saving fluids are transfusible into or out of bone marrow of a target bone when the cannula is penetrated into the target bone; a stylet which is engageable with the cannula; and means for causing penetration of the stylet and cannula, when mutually engaged, to a predefined depth α within the target bone with respect to an outer surface of the target bone, the depth α being irrespective of a thickness of tissue above the target bone.
