Abstract
Apparatus are disclosed for intraosseous fluid infusion or aspiration of bone marrow of a subject. Particular apparatus include a bone portal (bone-penetrating member) comprising axially-aligned distal and proximal sections. The proximal section extends in a distal direction from a proximate end of the bone portal and the distal section extends in the distal direction from the proximate section to the distal end of the bone portal. The bone portal also comprises a fluid-transport bore extending between a proximal opening in the proximal section and a distal opening in the distal section. At least a portion of the distal section has a cross-sectional area, perimeter, diameter and/or dimension greater than that of the proximal section.
