Abstract

Medical devices, medical procedure trays, kits and related methods are provided for use to perform medical procedures that require access to the interior of a bone. The devices, trays and methods allow multiple use of non-sterile medical devices with sterile medical devices for performing medical procedures requiring sterile conditions. A coupler assembly, capable of releasably attaching to a non-sterile medical device at one end and releasably attaching to one or more sterile medical devices at another end, and further comprising a containment bag which allows maintaining sterility of a non-sterile medical device which may be used in conjunction with sterile medical devices and procedures. The devices, trays, kits and methods enable the performance of multiple medical procedures with a single insertion into bone. For example, a vertebral procedure such as a vertebroplasty may be performed along with biopsy and/or bone marrow aspiration procedures, thereby reducing patient trauma and costs.

Claims4

Dependent claims

A coupler assembly operable to releasably attach a plurality of IO devices and releasably attach a non-sterile powered driver comprising:

a coupler housing;
a first end operable to releasably attach the plurality of intraosseous (IO) devices;
a first latch configured to resist detachment of an IO device from the first end;
a second end operable to releasably attach the non-sterile powered driver such that the powered driver can rotate the intraosseous device attached to the first end around a rotational axis extending through the first end and the second end;
a second latch configured to resist detachment of the driver from the second end;
a sterile containment bag proximate the second end comprising an opening operable to insert and enclose the non-sterile powered driver to prevent contamination of the IO devices by the non-sterile powered driver;
a tortuous path proximate the second end and proximate the sterile containment bag, wherein the tortuous path prevents contamination of the coupler housing following attachment with the non-sterile driver at the second end;
and
where at least a portion of the coupler housing is operable to be rotated relative to another portion of the coupler housing and relative to the containment bag around the rotational axis for insertion and securing of the IO device at the first end of the coupler assembly.
