Teleflex has been granted a patent for apparatuses, systems, and methods for sternal locators that aid in the placement of an intraosseous device into the sternum of a human patient. The invention involves a method for accessing bone marrow in the sternum, using a sternal locator with flexible tabs to secure the device and probes to penetrate the skin and contact the sternum. The method also includes manually inserting the intraosseous device and applying pressure until the tabs engage the device’s flanged portion.

A recently granted patent (Publication Number: US11771462B2) describes a method for accessing bone marrow in the sternum of a human patient. The method involves using a sternal locator, which includes a stabilizer with flexible tabs and probes, to locate the sternal notch on the patient's chest. The sternal locator is then pressed against the chest until the probes penetrate the skin and contact the anterior compact bone of the sternum. An intraosseous (IO) device, consisting of a penetrator and a hub, is manually inserted through a passageway in the sternal locator, and pressure is applied to the IO device until the flexible tabs engage the hub.

The patent also includes additional claims and variations of the method. One claim involves the use of an adhesive member and removable liner on the underside of the sternal locator, which is pressed against the patient's skin before inserting the IO device. Another claim involves delivering fluid through the IO device into the intraosseous space in the sternum. The patent also describes securing the stabilizer to the IO device after insertion, using a circumferential collar with a collar contact surface and a passageway for the penetrator. The alignment feature of the sternal locator is described as an arc-shaped surface, and the flexible tabs of the stabilizer have inwardly-projecting portions.

Another claim introduces an intraosseous device with an outer penetrator and an inner penetrator, both coupled to respective hubs. The sternal locator is used to locate the sternal notch and apply pressure until the probe penetrates the skin and contacts the anterior compact bone. The intraosseous device is then inserted through the passageway of the stabilizer, and pressure is applied to pierce the skin and bone until the flexible tab engages the outer penetrator hub. The inner penetrator can be withdrawn, leaving the outer penetrator coupled to the stabilizer to create a conduit in direct fluid communication with the intraosseous space.

Overall, this granted patent describes a method for accessing bone marrow in the sternum using a sternal locator and an intraosseous device. The method provides a precise and controlled approach for accessing the bone marrow, with various features and variations to enhance the procedure.
