Intraosseous access assembly

An intraosseous access assembly defining an axial direction, a radial direction, and a circumferential direction, the intraosseous access assembly comprising:

• a driver defined between a proximal driver end (PDE) and a distal driver end (DDE) in the axial direction, the driver defining a gripping portion between the PDE and the DDE, the driver configured to withstand impact along the axial direction, the driver comprising a driving portion defined in the PDE, the driving portion defining a female receiving end to accept a complementary/matched male tool bit enabling mated rotation of the driver;
• a stylet extending from the DDE of the driver, the stylet extending between a distal stylet end (DSE) and a proximal stylet end (PSE);
• a catheter hub removably couplable to the driver at the DDE;
• and
• a catheter extending from the catheter hub, the catheter extending between a proximal catheter end (PCE) and a distal catheter end (DCE), the catheter defining a longitudinal opening at the DCE,
• wherein the stylet extending from the DDE of the driver is selectively received through the catheter hub and the catheter, the stylet having a tip defined at the DSE and extending through the opening at the DCE.

An intraosseous access assembly, comprising:

• a driver defined between a proximal driver end (PDE) and a distal driver end (DDE), the driver defining a gripping portion between the PDE and the DDE, the driver defining a plurality of prongs extending from the DDE;
• a stylet extending from the DDE of the driver, the stylet extending between a distal stylet end (DSE) and a proximal stylet end (PSE);
• a catheter hub removably couplable to the driver at the DDE, the catheter hub defining a plurality of apertures for receiving respective prongs of the plurality of prongs of the driver,
• a catheter extending from the catheter hub, the catheter extending between a proximal catheter end (PCE) and a distal catheter end (DCE), the catheter defining a cutting edge and a longitudinal opening at the DCE,
• wherein the stylet extending from the DDE of the driver is selectively received through the catheter hub and the catheter, the stylet comprising a tapered tip defined at the DSE and extending through the opening at the DCE, the cutting edge of the catheter and the tapered tip of the stylet form a cutting tip at the DSE.
