Abstract
Bone marrow harvesting devices and methods of use for harvesting bone marrow from a biological source of bone marrow are provided that promote ease of use, and reduce patient pain and potential trauma to harvested bone marrow, wherein an exemplary bone marrow harvesting device includes an elongated shaft comprising a distal region, a proximal region, and a lumen extending therebetween, the distal region comprising a plurality of through-wall apertures in fluid communication with the lumen; and an expandable member disposed along the distal region thereof and configured to transition between a collapsed state and an expanded state for vibrating to disrupt the bone marrow. Methods of using the inventive bone marrow harvesting device to provide more efficient bone marrow disruption, improve the efficiency of bone marrow aspiration, and increase the quantity of bone marrow harvested in a single procedure are also provided.
