A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

A bone marrow access apparatus includes a bone penetrating member and a cap. The bone penetrating member includes a tubular insertion portion, and a head portion provided at a proximal end of the tubular insertion portion. A cross-sectional shape of the head portion is wider than a cross-sectional shape of the tubular insertion portion. A recess is provided in the head portion, and an internal channel is provided through the head portion and the tubular insertion portion. The cap accommodates the head portion of the bone penetrating member therein. The cap includes a lower wall which covers at least a part of a distal side of the head portion, and a projection which projects into the recess of the head portion.

A bone marrow harvesting device can include: a hub inserted into a bone marrow cavity; a catheter inserted into the hub and having a syringe detachably connected to one side thereof; and a holder connected to one end of the catheter such that the catheter is movable along the longitudinal direction. The bone marrow harvesting device, when harvesting bone marrow, can not only easily and stably move the position of a catheter inserted into a bone marrow cavity, but can also harvest the bone marrow in a state where the catheter is stably fixed after the position of the catheter is moved.

An intraosseous needle assembly includes a needle having a first cylindrical shaft. The shaft having a distal end, a proximal end, and a wall defining an inner channel. The first cylindrical shaft includes threading protruding from the wall along a proximal portion of the first cylindrical shaft. The needle further includes a needle head extending from the proximal end of the first cylindrical shaft. The needle assembly may further include a stylet, the stylet having a second cylindrical shaft having a first end and a second end and a stylet head extending from the second end. The stylet head includes a proximal surface and a distal surface, a pair of substantially parallel second side walls, a pair of rounded end sections joining the second side walls, a protrusion extending from the distal surface, and a tapered section extending from the distal surface to the second cylindrical shaft.

Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

The present disclosure is generally directed to a delivery device housed within an outer cartridge and useful for delivering a fluid to the IO space of a subject at a relatively constant volumetric flow rate over an extended period of time. The delivery device may be fluidly coupled to an existing IO access device or IV line positioned in the IO space of the subject or may be coupled to an IO access device disposed within the outer cartridge.

The invention involves a device and method for acquiring bone marrow aspirate. The system includes an elongated cannulated fastener having a threaded end for attachment to a bone. The threaded portion includes a directional aperture sized to allow marrow to be drawn into the cannula. The directional aperture also allows the user to direct the aperture in a desired direction within the bone for acquisition of the marrow. The distal end of the cannulated fastener includes a connector which may be in the form of a Luer lock to allow vacuum to be applied to the cannula for drawing the marrow into a syringe or the like.

A device for delivering a bone material to a surgical site is provided. The device comprises a body having an upper portion and a lower portion. The lower portion of the body is substantially transverse to the upper portion and has an opening for receiving a bone material. An internal chamber is disposed within the upper portion and the lower portion, and a plunger is slidably disposed in at least the internal chamber of the body. The plunger has a distal end configured for delivering the bone material out of the lower portion of the body, wherein movement of the plunger in a first position toward the lower portion of the body delivers the bone material from the lower portion of the body to the surgical site. Methods of delivering the bone material are also provided.

Fluid communication devices and supporting structures may be provided for use with intraosseous devices. Apparatus and methods may also be provided to communicate fluids with an intraosseous device.

A surgical or arthroscopic method for resurfacing at least one surface of a hip joint of a human patient, using a medical device comprising an artificial hip joint surface, wherein the hip joint surface comprising an acetabulum surface and a caput femur surface, said method comprising the steps of: creating at least one hole passing into the hip joint, dissecting and preparing the hip joint, introducing at least one artificial hip joint surface, comprising at least one of an artificial acetabulum surface and an artificial caput femur surface, wherein said at least one artificial hip joint surface, comprising a first sealing member, creating a sealed hollow space between said first sealing member and one of the acetabulum surface or said artificial acetabulum surface and one of the caput femur surface or said artificial caput femur surface, selecting at least one artificial hip joint surface and injecting a material into said hollow space.
