Patent ID: 8870849

Claim:
A catheter hub, comprising: a distal assembly including a distal hub member adapted to be fixedly attached to an outer catheter; a proximal assembly including a proximal hub member adapted to be fixedly attached to an inner catheter disposed through the outer catheter, and wherein an outer lateral surface of the proximal assembly includes a planar top surface of the proximal assembly and the proximal hub member includes a planar bottom surface that engages the planar top surface of the proximal assembly when the proximal hub member is detachably attached to the outer lateral surface of the proximal assembly along a longitudinal axis of the proximal assembly that extends between a distal end of the proximal assembly and a proximal end of the proximal assembly that is further away from the distal assembly than the distal end of the proximal assembly; and an elongate member connecting the proximal and distal assemblies such that the proximal and distal assemblies are capable of longitudinal translation relative to one another, wherein the proximal and distal hub members interlock with one another when the proximal and distal assemblies are brought together.
