Abstract
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.

Claim 1
Independent Claim
203 words
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.
Claim 2
Independent Claim
203 words
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.
Claim 3
Independent Claim
185 words
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.
Claim 4
Independent Claim
185 words
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.
