The apparatus may include a driver, a plunger operating and cartridge assembly mechanism, a cartridge assembly having a fluid reservoir and a bone penetrating needle.

Claims

1-31. -31. (canceled)

32. An apparatus for delivering a quantity of medication to bone marrow of a bone comprising:

a driver assembly;

a plunger operating and cartridge drive mechanism rotatably engaged with the driver assembly;

a removable cartridge assembly including a drive connector attached thereto, the drive connector operable to be releasably engaged with one end of the plunger operating and cartridge drive mechanism and operable to be rotated by the plunger operating and cartridge drive mechanism;

a bone penetrating needle engaged with the cartridge assembly opposite from the drive connector, wherein rotation of the cartridge assembly inserts the bone penetrating needle into the bone and bone marrow;

a plunger operating assembly including a first retracted position and a second released position;

a retractable sleeve operable to slide longitudinally relative to the plunger operating and cartridge drive mechanism; and

a latch assembly operable to release the plunger operating assembly from the first retracted position to the second released position in response to rotation of the plunger operating and cartridge drive mechanism and longitudinal movement of the retractable sleeve.

33. The apparatus of claim 32, wherein the drive connector further comprises at least one magnet operable to releasably engage the cartridge assembly with the one end of the plunger operating and cartridge drive mechanism.

34. The apparatus of claim 32, further comprising a ball and detent mechanism operable to releasably engage the cartridge assembly with the one end of the plunger operating and cartridge drive mechanism.

35. The apparatus of claim 32, wherein the plunger operating and cartridge drive mechanism comprises:

a first spring operable to move the plunger operating assembly from the first retracted position to the second released position; and

a second spring operable to bias the retractable sleeve to move from a retracted position to an extended position.

36. The apparatus of claim 32, wherein the latch assembly comprises:

a first position operable to releasably engage the plunger operating assembly in the first retracted position; and

a second position that allows movement of the plunger operating assembly from the first retracted position to the second released position.

37. The apparatus of claim 32, wherein the latch assembly comprises:

a pawl latch including a first position that releasably engages the plunger operating assembly in the first retracted position and a second position that allows movement of the plunger operating assembly from the first retracted position to the second released position; and

a spring operable to bias the pawl latch in the first position.

38. The apparatus of claim 32, wherein the plunger operating and cartridge drive mechanism is operable to deliver a fluid contained in a fluid reservoir included in the cartridge assembly after the bone penetrating needle has been inserted into the bone marrow.

39. The apparatus of claim 32, wherein the plunger operating assembly comprises a spring loaded plunger operating assembly.

40. The apparatus of claim 32, wherein the retractable sleeve comprises a spring loaded retractable sleeve.

41. The apparatus of claim 32, wherein the cartridge assembly includes a fluid reservoir with a plunger assembly slidably disposed in the fluid reservoir, the fluid reservoir releasably engaged with a hub including a Luer fitting.

42. The apparatus of claim 32, wherein the bone penetrating needle comprises a closed tip including at least one cutting edge operable for drilling into the bone.

43. The apparatus of claim 32, wherein the driver assembly comprises, a motor, a power source, and a gearbox.

44. An apparatus for delivering a quantity of medication to bone marrow of a bone comprising:

a housing defined in part by a first end and a second end;

a motor disposed in the housing proximate the second end of the housing;

a drive shaft coupled to and extending from the motor;

a rotational drive housing including a first end and a second end with the second end securely engaged with the drive shaft;

a removable cartridge assembly including a fluid reservoir with a bone penetrating needle releasably coupled to a first end and a drive connector coupled to a second end, the drive connector operable to releasably engage the cartridge assembly with the first end of the rotational drive housing; and

a plunger operating and cartridge drive mechanism including;

the rotational drive housing operable to transmit rotational forces from the drive shaft to the cartridge assembly;

a retractable sleeve slidably disposed in and extending from the first end of the rotational drive housing such that the retractable sleeve is operable to slide longitudinally relative to the drive housing;

a plunger operating assembly slidably disposed within a longitudinal bore of the rotational drive housing, the plunger operating assembly including a first retracted portion and a second released position; and

a latch assembly operable to release the plunger operating assembly from the first retracted position to the second released position in response to rotation of the plunger operating and cartridge drive mechanism and longitudinal movement of the retractable sleeve.

45. The apparatus of claim 44, wherein the plunger operating and cartridge drive mechanism comprises:

a first spring operable to move the plunger operating assembly from the first retracted position to the second released position; and

a second spring operable to bias the retractable sleeve to move from a retracted position to an extended position.

46. The apparatus of claim 44, wherein the latch assembly comprises:

a first position operable to releasably engage the plunger operating assembly in the first retracted position;

a second position that allows movement of the plunger operating assembly from the first retracted position to the second released position; and

a spring operable to bias the latch assembly in the first position.

47. The apparatus of claim 46, wherein the latch assembly comprises a pawl latch assembly.

48. The apparatus of claim 44, wherein the plunger operating and cartridge drive mechanism is operable to deliver a fluid contained in the fluid reservoir after the bone penetrating needle has been inserted into the bone marrow.

49. The apparatus of claim 44, wherein the housing further comprises:

a receiver portion including a generally hollow, tubular configuration formed in the first portion of the housing, the receiver portion including a first, open end with portions of the retractable sleeve slidably disposed therein and one end of the retractable sleeve extending from the first end of the receiver portion and a second, closed end to protect components associated with the plunger operating and cartridge drive mechanism; and

a handle extending from the receiver portion;

50. The apparatus of claim 44, wherein the drive connector is further operable to:

engage with and be rotated by the plunger operating and cartridge drive mechanism during insertion of the bone penetrating needle into the bone marrow of the bone; and

release from the plunger operating and cartridge drive mechanism after insertion of the bone penetrating needle into the bone marrow of the bone.

51. The apparatus of claim 44, wherein the fluid reservoir comprises a fluid including medication.
