PUMPING APPARATUSES AND METHODS FOR FLUID INFUSION

1 - 30 . (canceled)

31 . A pumping apparatus for fluid infusion, the apparatus comprising:

a pump housing having one or more walls extending from a proximal end to a distal end;

a hub rotatably coupled to the proximal end of the pump housing; and

a peristaltic pump coupled to the hub and configured to cause fluid flow through a flexible tube when the hub is rotated relative to the pump housing, at least a portion of the pump disposed within the pump housing;

where the proximal end of the pump housing is configured to be coupled in fixed relation to a housing of a driver.

32 . The apparatus of claim 31 , where the hub is configured to be removably coupled to a rotatable driveshaft of the driver.

33 . The apparatus of claim 32 , where the pump housing has a transverse dimension that is between 5 to 10 times a transverse dimension of the rotatable driveshaft.

34 . The apparatus of claim 31 , where the driver is configured to insert an intraosseous device into bone or associated bone marrow.

35 . The apparatus of claim 31 , where at least one of the one or more walls defines an interior cam surface and the peristaltic pump comprises a rotor configured to compress at least a portion of the flexible tube between the rotor and the interior cam surface.

36 . The apparatus of claim 35 , where the rotor comprises a non-circular cross-section.

37 . The apparatus of any of claim 35 , where the rotor comprises a rotor hub and a plurality of lobe members coupled to the rotor hub.

38 . The apparatus of claim 37 , where the pump housing defines an internal recess adjacent the distal end of the pump housing, the recess configured to receive the plurality of lobe members.

39 . The apparatus of claim 31 , further comprising a sidewall having a barrel portion that extends longitudinally from the proximal end of the pump housing to define a longitudinal channel configured to receive at least a portion of the driver.

40 . The apparatus of claim 39 , where the sidewall comprises a trigger portion that extends at a non-parallel angle from the barrel portion, the trigger portion configured to receive a portion of a handle of the driver.

41 . The apparatus of claim 31 , where at least a portion of the pump housing is removable.

42 . The apparatus of claim 41 , where the distal end of the pump housing is removable from the proximal end of the pump housing.

43 . The apparatus of claim 31 , where the pump housing defines an inlet and an outlet.

44 . The apparatus of claim 43 , where the inlet and outlet are defined on substantially a same side of the pump housing.

45 . The apparatus of claim 43 , where the inlet and the outlet are substantially co-planar.

46 . The apparatus of claim 43 , where at least a portion of the flexible tube extends through at least one of the inlet and the outlet of the pump housing.

47 . The apparatus of claim 31 , comprising a releasable clamp configured to selectively block fluid communication through the flexible tube.

48 . The apparatus of claim 31 , comprising a flow regulator configured to be in fluid communication with the flexible tube.

49 . A method for fluid infusion, the method comprising:

coupling a rotatable driveshaft of a driver to a rotatable hub of a pump, the driver configured to insert an intraosseous device into bone or associated marrow; and

actuating the pump to cause fluid flow through a flexible tube in fluid communication with the pump.

50 . The method of claim 49 , comprising:

inserting an intraosseous device into bone or associated bone marrow with the driver; and

placing the intraosseous device into fluid communication with the pump.
