Abstract

An apparatus and method for accessing the bone marrow of a human'"'"'s sternum is provided. The apparatus includes a tissue penetrator configured to penetrate the sternum, a trigger mechanism configured to engage when the tissue penetrator contacts the sternum and a depth control mechanism operable to limit the penetration of the tissue penetrator into the sternum to a pre-selected depth.

Claims

1. A method for accessing the intraosseous space of a subject'"'"'s sternum comprising:

contacting the skin covering the manubrium of the subject with a device having;

a disposable cartridge and a reusable handle;

the disposable cartridge having;

a tissue penetrator configured to penetrate the sternum and provide access to the intraosseous space of the sternum, the tissue penetrator comprising an outer cannula and an inner trocar;

a depth control mechanism operable to control the depth of penetration of the tissue penetrator into the sternum;

the depth control mechanism including depth probes disposed adjacent to the tissue penetrator; and

the depth probes operable to deploy the tissue penetrator and to allow the driver to insert the tissue penetrator into the intraosseous space of the sternum;

the reusable handle having;

a driver, disposed within the reusable handle, operable to drive a portion of the tissue penetrator into the sternum; and

the reusable handle configured to releasably engage the disposable cartridge;

advancing the tissue penetrator a sufficient distance to place at least a portion of the cannula in the intraosseous space;

releasing the reusable handle by twisting the disposable cartridge from the reusable handle; and

accessing the intraosseous space via a connector located on the disposable cartridge.

2. An apparatus for accessing bone marrow disposed in an intraosseous space of a sternum comprising:

a driver;

a disposable cartridge including a tissue penetrator operable to penetrate the sternum and provide access to bone marrow in the intraosseous space of the sternum;

the tissue penetrator having an inner trocar and an outer cannula;

the disposable cartridge including a depth control mechanism operable to control depth of penetration of the tissue penetrator into the sternum;

the depth control mechanism including depth probes disposed adjacent to the tissue penetrator;

the depth probes operable to deploy the tissue penetrator and to allow the driver to insert the tissue penetrator into the intraosseous space of the sternum;

a reusable handle configured to releasably engage the disposable cartridge;

the disposable cartridge having a detent to releasably engage to a recess located on the reusable handle;

the detent and recess operable to be twisted to releasably engage the disposable cartridge with the reusable handle;

the driver disposed within the reusable handle; and

the driver operable to drive the tissue penetrator to a desired level in the bone marrow of the sternum.

3. The apparatus of claim 2 wherein the driver further comprises a power source selected from the group consisting of a manual power source, a battery, a coiled spring, a compressed gas, and a solar power cell.

4. The apparatus of claim 2 wherein the driver comprises a spring.

5. The apparatus of claim 2 further comprising:

the driver including a power source disposed in a housing;

a depth control mechanism including depth probes operable to control the depth of penetration of the tissue penetrator into the sternum; and

the tissue penetrator and the depth probes extending from the driver, the driver operable to insert the tissue penetrator to a pre-selected depth in the intraosseous space of the sternum.

6. The apparatus of claim 5 wherein the power source further comprises:

a spring with one end of the spring disposed adjacent to and contacting an end member;

the tissue penetrator and the depth probes extending from the end member opposite from the spring; and

a connector attached to the end member and aligned with the tissue penetrator to provide access through the connector and the tissue penetrator into the intraosseous space.

7. The apparatus of claim 2, wherein the driver is a manual driver.
