Assembly for coupling powered driver with intraosseous device

Abstract

Apparatus and methods are provided to remove biopsy specimens from a bone and/or associated bone marrow using a powered driver and an intraosseous (IO) needle set. The powered driver may rotate the IO needle set at an optimum speed to obtain a biopsy sample of bone and/or bone marrow. Apparatus and methods may also be provided for aspiration of bone marrow and/or stem cell transplant procedures. The apparatus may include a powered driver, a coupler assembly, a containment bag or sterile sleeve and various IO needles and IO needle sets with associated hubs and/or hub assemblies. Each IO needle set may include a cannula or catheter and an associated trocar stylet with respective tips operable to penetrate a bone and/or bone marrow with minimum trauma to a patient. Each hub assembly may be used to releasably dispose a respective stylet within an associated generally hollow cannula. Some coupler assemblies and/or hub assemblies may also be used with manual drivers.

What is claimed is: 
     
         1 . An apparatus operable to insert an intraosseous device into a bone and associated bone marrow, the apparatus comprising:
 a powered driver including a housing having distal end and a proximal end; and   a coupler assembly having a first end and a second end;   the intraosseous device including a first end and a second end, the first end of the intraosseous device operable to penetrate the bone and associated bone marrow;   the first end of the coupler assembly configured to releasably engage the second end of the intraosseous device, and the second end of the coupler assembly configured to releasably engage the powered driver.
