Abstract

An apparatus and method for harvesting bone and bone marrow are provided. The apparatus may include a driver operable to be releasably engaged with an intraosseous device. The intraosseous device may include a cannula having a first end operable to penetrate bone and bone marrow and to allow retrieval of portions of bone and/or bone marrow. The cannula may have a second end operable to be releasably engaged with bone marrow sampling equipment. The apparatus may include a removable trocar. The removable trocar may have an inner channel operable to convey portions of bone and/or bone marrow. The removable trocar may have an inner channel and a side port communicating with the inner channel. The removable trocar may have a first end operable to penetrate bone and bone marrow.

Claims

1. An intraosseous device for harvesting bone and bone marrow comprising:

an outer penetrator having a first end operable to penetrate a bone and associated bone marrow;

the outer penetrator having a second end with a hub attached thereto;

the hub having a first end operable to accommodate harvesting bone marrow;

a tapered opening formed in the first end of the hub;

the tapered opening sized to receive an associated Luer fitting;

threads formed on exterior portions of the hub adjacent to the first end of the hub;

the hub having a second end with a flange configuration compatible with contacting a patient'"'"'s skin adjacent to an insertion site;

the outer penetrator having a longitudinal bore extending from the first end to the second end thereof;

the tapered opening formed in the first end of the hub in fluid communication with the longitudinal bore of the outer penetrator;

an inner penetrator operable to be slidably disposed in the longitudinal bore of the outer penetrator;

the inner penetrator having a first end operable to penetrate the bone marrow in cooperation with the first end of the outer penetrator;

the inner penetrator having a second end spaced longitudinally from the first end of the inner penetrator;

a connector having a first end and a second end with the inner penetrator extending from the second end of the connector;

the connector operable to releasably attach the second end of the inner penetrator with the threads formed on the first end of the hub proximate the second end of the outer penetrator;

the connector including a tapered portion sized to fit within the tapered opening formed in the hub when the inner penetrator is disposed within the longitudinal bore of the outer penetrator and is releasably attached to the second end of the outer penetrator;

the first end of the inner penetrator disposed proximate the first end of the outer penetrator when the second end of the inner penetrator is releasably attached to the second end of the outer penetrator;

a connector receptacle disposed within the first end of the connector;

the connector receptacle operable to releasably engage a powered driver to allow the powered driver to install the intraosseous device into the bone and bone marrow at an insertion site;

the inner penetrator comprising a tip having a longitudinal groove defining a slot that runs along a side of the inner penetrator, wherein the slot of the longitudinal groove is operable to allow bone chips and bone tissue to exit from an insertion site of the intraosseous device into the bone;

a trocar operable to be slidably disposed within the longitudinal bore of the outer penetrator after the inner penetrator has been removed therefrom;

the trocar having a length greater than the length of the outer penetrator;

the trocar having a first end operable to extend from the first end of the outer penetrator when the trocar is slidably disposed in the longitudinal bore; and

the first end of the trocar having a first, open position and a second, closed position.

2. The apparatus of claim 1 further comprising:

the connector having threads operable to be releasably engaged with the threads of the hub when the inner penetrator is slidably disposed in the longitudinal bore of the outer penetrator.

3. An intraosseous device comprising:

an outer penetrator having a first end operable to penetrate a bone and associated bone marrow;

the outer penetrator having a second end with a hub attached thereto;

a tapered opening formed in a first end of the hub;

the tapered opening sized to receive an associated Luer fitting;

threads formed adjacent to the first end of the hub;

the hub having a second end with a flange configuration compatible with contacting a patient'"'"'s skin adjacent to an insertion site;

the outer penetrator having a longitudinal bore extending from the first end to the second end thereof;

the tapered opening formed in the first end of the hub in fluid communication with the longitudinal bore of the outer penetrator;

an inner penetrator operable to be slidably disposed in the longitudinal bore of the outer penetrator;

the inner penetrator having a first end operable to penetrate the bone marrow in cooperation with the first end of the outer penetrator;

the inner penetrator having a second end spaced longitudinally from the first end of the inner penetrator;

a connector operable to releasably attach the second end of the inner penetrator with the threads formed on the first end of the hub;

the connector including a tapered portion sized to fit within the tapered opening formed in the hub when the inner penetrator is disposed within the longitudinal bore of the outer penetrator and is releasably attached to the second end of the outer penetrator;

the connector comprising a connector receptacle sized to be releasably engaged with a powered driver to allow the powered driver to rotate and install the intraosseous device at an insertion site by rotation of the intraosseous device;

an annular slot formed in the second end of the hub; and

the annular groove sized to receive one end of a protective cover therein.

4. The intraosseous device of claim 3 further comprising the first end of the hub operable to accommodate harvesting of bone marrow after installing the intraosseous device at an insertion site using the powered driver.

5. An intraosseous device comprising:

an outer penetrator having a first end operable to penetrate a bone and associated bone marrow;

the outer penetrator having a second end with a hub attached thereto;

an opening formed in a first end of the hub;

the opening sized to receive an associated Luer fitting;

threads formed adjacent to the first end of the hub;

the hub having a second end with a flange configuration compatible with contacting a patient'"'"'s skin adjacent to an insertion site;

the hub securely attached to the outer penetrator whereby the distance between the flange configuration and the first end of the outer penetrator remains constant during insertion and removal of the intraosseous device from an insertion site;

the outer penetrator having a longitudinal bore extending from the first end to the second end thereof;

the tapered opening formed in the first end of the hub in fluid communication with the longitudinal bore of the outer penetrator;

an inner penetrator operable to be slidably disposed in the longitudinal bore of the outer penetrator;

the inner penetrator having a first end operable to penetrate the bone marrow in cooperation with the first end of the outer penetrator;

the inner penetrator having a second end spaced longitudinally from the first end of the inner penetrator;
