The handle is configured to releasably engage the intraosseous needle. The handle includes a cylindrical body portion, a handle portion, and a channel. The cylindrical body portion includes a distal end configured to receive the proximal end of the intraosseous needle. The handle portion extends from the cylindrical body portion and has a bulb-like cross-sectional shape and opposing first and second substantially planar surfaces.

a handle portion extending from the cylindrical body portion having a bulb-like cross-sectional shape and opposing first and second substantially planar surfaces, wherein the handle portion comprises a notch configured to engage the proximal end of the intraosseous needle in a second operating configuration for immobilizing the intraosseous needle relative to the bone; and a channel configured to receive the proximal end of the driving shaft. ### Claim 2 (depends on 1) The system of claim 1, wherein the notch of the handle portion includes a curved surface connecting a first pair of opposing flat surfaces, the opposing flat surfaces configured to engage a second pair of opposing flat surfaces of the proximal end of the intraosseous needle. ### Claim 3 (depends on 1) The system of claim 1, further comprising the driving shaft including a distal end configured to engage the proximal end of the intraosseous needle and a proximal end including a flat portion configured to be driven. ### Claim 4 (depends on 3) The system of claim 3, wherein the flat portion of the driving shaft is configured to engage a chuck of a drill. ### Claim 5 (depends on 3) The system of claim 3, wherein the channel includes a flat portion configured to engage and drive the flat portion of the driving shaft. ### Claim 6 (depends on 3) The system of claim 3, wherein the proximal end of the driving shaft protrudes from the channel such that the proximal end of the driving shaft can be pressed to disengage the driving shaft from the handle. ### Claim 7 (depends on 1) The system of claim 1, wherein the intraosseous needle further comprises a shaft extending to the distal end and a head portion extending to the proximal end, and wherein the shaft comprises a plurality of threads. ### Claim 8 (depends on 1) The system of claim 1, wherein the cylindrical body portion includes first and second opposing slots that provide an opening between an outer surface of the cylindrical body portion and the channel. ### Claim 9 A handle configured to engage an intraosseous needle including a distal end configured for insertion into a bone and a proximal end configured to extend from the bone, the handle comprising: a cylindrical body portion including a distal end configured to receive a proximal end of a driving shaft engaged with the intraosseous needle, the cylindrical body portion defining a longitudinal axis of the handle; a flared handle portion having a width larger than a width of the cylindrical body portion, the flared handle portion including a first lobe, a second lobe, and a notch positioned between the first lobe and the second lobe, wherein the notch includes a curved surface connecting a first pair of opposing flat surfaces, the opposing flat surfaces configured to engage a second pair of opposing flat surfaces of the proximal end of the intraosseous needle while threadably engaging a component with threads of the proximal end of the intraosseous needle; and a channel extending between a proximal end of the flared handle portion and the distal end of the cylindrical body portion along the longitudinal axis. ### Claim 10 (depends on 9) The handle of claim 9, wherein the distal end of the cylindrical body portion receives the proximal end of the driving shaft engaged with the intraosseous needle in a first operating configuration configured for inserting the intraosseous needle into the bone. ### Claim 11 (depends on 9) The handle of claim 9, wherein the distal end of the cylindrical body portion includes first and second opposing slots that provide an opening between an outer surface of the cylindrical body portion and the channel. ### Claim 12 (depends on 9) The handle of claim 9, wherein a portion of the channel proximate the distal end of the cylindrical body portion comprises a first rib configured to engage a head portion of the intraosseous needle. ### Claim 13 (depends on 9) The handle of claim 9, wherein the channel is configured to receive the driving shaft coupled to the proximal end of the intraosseous needle. ### Claim 14 (depends on 13) The handle of claim 13, wherein a portion of the channel proximate a proximal end of the channel includes a flat surface configured to engage a flat surface of the proximal end of the driving shaft to drive the driving shaft. ### Claim 15 (depends on 14) The handle of claim 14, wherein the proximal end of the driving shaft protrudes into the notch such that the proximal end of the driving shaft can be pressed to disengage the driving shaft from the handle. ### Claim 16 A method for inserting a medical device into an interior of a bone, the method comprising: coupling a driving shaft to an intraosseous needle; engaging the driving shaft and a proximal end of the intraosseous needle with a channel of a handle, the handle including: a cylindrical body portion including a distal end configured to receive the proximal end of the intraosseous needle, and a flared handle portion having a width larger than a width of the cylindrical body portion, the flared handle portion including a first lobe, a second lobe, and a notch positioned between the first lobe and the second lobe; actuating the handle to insert the intraosseous needle into the bone; and pushing on a portion of a distal end of the driving shaft that protrudes into the notch to disengage the driving shaft from the handle. ### Claim 17 (depends on 16) The method of claim 16, further comprising: removing the driving shaft from the intraosseous needle; engaging a first pair of opposing flat surfaces of the notch of the handle with a second pair of opposing flat surfaces of the proximal end of the intraosseous needle; applying a first torque to a component to threadably couple the component to the proximal end of the intraosseous needle; and applying a second torque to the intraosseous needle with the handle, the second torque substantially opposing the first torque to immobilize the intraosseous needle relative to the bone. ### Claim 18 (depends on 17) The method of claim 17, wherein the handle abuts a surface of a patient while the notch is engaged with the proximal end of the intraosseous needle. ### Claim 19 (depends on 16) The method of claim 16, further comprising: engaging the distal end of the cylindrical body portion with the proximal end of the intraosseous needle such that the proximal end of the intraosseous needle is received with the channel; squeezing the cylindrical body portion; and extracting the intraosseous needle from the bone by exerting an upward force on the proximal end of the intraosseous needle with the handle. ### Claim 20 (depends on 19) The method of claim 19, wherein the cylindrical body portion comprises first and second opposing slots that extend between an outer surface of the cylindrical body portion and the channel proximate the distal end of the cylindrical body portion, the first and second opposing slots configured to expand when engaging the proximal end of the intraosseous needle to allow the distal end of the cylindrical body portion to receive the proximal end of the intraosseous needle in the channel and contract when squeezing the distal end of the cylindrical body portion to secure the proximal end of the intraosseous needle within the channel when extracting the intraosseous needle from the bone. ### Claim 21 (depends on 20) The method of claim 20, wherein a portion of the channel proximate a proximal end of the cylindrical body portion comprises a first rib configured to engage a head of the intraosseous needle.
