Intraosseous device and methods for accessing bone marrow in the sternum and other target areas

Apparatus for accessing bone marrow proximate an insertion site comprising:

• a driver operable to insert an intraosseous device into the bone marrow, the intraosseous device including at least a cannula;
• the driver having a handle with an exterior surface configured to be grasped by the user and a connector extending from the handle, where the connector is configured to releasable secure the handle relative to the cannula;
• the intraosseous device disposed in a kit prior to engagement with the driver;
• the intraosseous device having a tip;
• the driver and intraosseous device being configured such that distance between the tip and the exterior surface of the driver will remain substantially constant during insertion of the intraosseous device;
• a scalpel disposed in the kit;
• and
• the scalpel operable to form an incision in soft tissue covering the insertion site after removing the scalpel from the kit.

Apparatus for accessing bone marrow of a sternum comprising:

• an intraosseous needle set configured to penetrate the sternum and provide access to the bone marrow of the sternum;
• a driver operable to insert the IO needle set into the bone marrow of the sternum;
• a guide mechanism operable to stabilize the intraosseous needle set during insertion into the bone marrow of the sternum;
• the guide mechanism including a generally hollow, cylindrical portion operable to be inserted into an incision formed in soft tissue covering the sternum;
• the generally hollow, cylindrical portion having an inside diameter operable to receive portions of the intraosseous needle set therein and to allow rotation of the intraosseous needle set during insertion relative to the generally hollow, cylindrical portion;
• a generally disk shaped portion with the hollow, cylindrical portion extending therefrom and unitary with the generally disk shaped portion;
• an opening formed in the disk shaped portion adjacent to and communicating with the elongated cylindrical portion;
• and the opening formed in the disk having a generally coned shaped surface operable to guide one end of the intraosseous needle set therethrough.

An intraosseous device operable to penetrate a bone and associated bone marrow comprising:

• a hub having a first end operable to be releasably engaged with a connector and a second end operable to be disposed adjacent to an insertion site for the intraosseous device;
• a first opening formed in the first end of the hub;
• a first longitudinal bore extending from the first opening through the hub to a second opening formed in the second end of the hub;
• an outer penetrator having a first end securely disposed within the longitudinal bore of the hub proximate the first opening in the hub;
• the outer penetrator having a second end extending from the second opening of the hub;
• a depth limiter having a first end engaged with the hub;
• the depth limiter disposed around exterior portions of the outer penetrator extending from the second end of the hub;
• and
• a second end of the depth limiter spaced a selected distance from a tip of the intraosseous device.

Apparatus for accessing bone marrow in a sternum comprising:

• a driver operable to insert an IO needle set into the bone marrow of the sternum;
• the intraosseous needle set operable to penetrate the sternum and provide access to bone marrow of the sternum;
• the intraosseous needle set including an outer cannula having a tip and an inner trocar;
• a hub having a flange operable to stabilize the intraosseous needle set after inserting the intraosseous needle set into the bone marrow in the sternum where the hub is configured to be removably coupled to the driver;
• and a collar extending from the hub to a distal end disposed between the flange and the tip, the collar disposed around and in non-adjustably fixed relation to the cannula such that the distal end of the collar is configured to limit depth of penetration of the intraosseous needle set into the bone marrow of the sternum;
• where the apparatus is configured such that the distance between the distal end of the collar and the tip of the outer cannula will remain substantially constant during insertion of the intraosseous needle set into the sternum.

Apparatus operable to direct and limit depth of penetration of an intraosseous device into bone marrow proximate an insertion site for the intraosseous device, comprising:

• an elongated, hollow portion operable to be inserted into an incision formed in soft tissue covering the insertion site;
• the elongated, hollow portion having a first end with an enlarged portion of the apparatus disposed adjacent thereto;
• the elongated, hollow portion having a second end operable to engage portions of an anterior cortex proximate the insertion site without penetrating the anterior cortex;
• and
• the enlarged portion of the apparatus operable to removably receive a needle set of the intraosseous device to limit movement of the intraosseous device through the elongated, hollow portion.

Apparatus operable to access bone marrow proximate an insertion site comprising:

• an intraosseous device including an outer penetrator, an inner penetrator, and a connector securely engaged with a manual driver;
• the manual driver operable to insert portions of the intraosseous device through an anterior cortex of a bone and into adjacent bone marrow;
• the manual driver defined in part by a handle;
• and
• the connector configured to releasably secure the handle and inner penetrator relative to the outer penetrator.
