Assembly for coupling powered driver with intraosseous device
First Claim
1. Apparatus operable to insert an intraosseous device into a bone and associated bone marrow, the apparatus comprising:
- a powered driver having a housing with one end of a drive shaft extending therefrom;
the intraosseous device having a first end operable to be inserted into the bone and associated bone marrow;
a coupler assembly having a first end including a first latch mechanism operable to be releasably engaged with a second end of the intraosseous device;
the coupler assembly having a second end including a second latch mechanism operable to be releasably engaged with the one end of the drive shaft; and
a spring that;
urges the first latch mechanism toward a locked configuration if the first latch mechanism is in an unlocked configuration, andurges the second latch mechanism toward a locked configuration if the second latch mechanism is in an unlocked configuration.

Abstract
Apparatus and methods are provided to remove biopsy specimens from a bone and/or associated bone marrow using a powered drive 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.
