This application is a continuation of U.S. patent application Ser. No. 11/253,467, filed Oct. 29, 2005, and entitled “Apparatus and Method to Access the Bone Marrow”; which is a divisional application of U.S. patent application Ser. No. 10/449,476, filed May 30, 2003, and entitled “Apparatus and Method to Access the Bone Marrow”, now U.S. Pat. No. 7,699,850; which claims priority to U.S. Provisional Patent Application Ser. No. 60/384,756, filed May 31, 2002, and entitled “Apparatus and Method to Provide Access to Bone Marrow.” The contents of each of the above-identified disclosures are incorporated hereby in their entirety by reference.
This application is to patent application entitled “Apparatus and Method to Provide Emergency Access To Bone Marrow”, Ser. No. 10/449,503, filed May 30, 2003; and to patent application, entitled “Apparatus and Method to Access the Bone Marrow for Oncology and Stem Cell Applications”, Ser. No. 10/448,650, Filed May 30, 2003, which claims priority from the same provisional application.
A further complicating factor in achieving IV access occurs the “in the field” e.g. at the scene of an accident or during ambulance transport where it is difficult to see the target and excessive motion make accessing the venous system very difficult.
FIGS. 3A and 38 illustrate yet another embodiment of the present invention. Apparatus 10 b generally includes housing 12 and a penetrator assembly (not expressly shown). Housing 12 includes handle 16 and on/off switch 22. Penetrator assembly may include penetrator (not expressly shown) and a connector, for example a pentagonal connector 20 as shown in FIG. 3A. As shown in FIG. 3B, housing 12 encloses motor 30, power supply 32, for example four or more AA batteries, motor connecting wires 34 between power supply 32 and motor 30 and switch connecting wires 36 between on/off switch 22 and power supply 32. The power supply to the apparatus may be any suitable number of AA batteries or any other type of battery, a source of direct current, a source of alternating current or a source of air or gas power. The motor may be reciprocating or rotational. Thruster bearing 45, for example a washer, may be located adjacent to housing 12 where drill shaft 40 exits housing 12. Thruster bearing 45 prevents the thrust or penetration force of drilling from being placed on gear assembly 38 as penetrator is drilled into bone. FIG. 3C shows one embodiment of the invention where drill shaft 40 may be separated into two interdigitating pieces at 42 in order to allow the two ends of drill shaft 40 to slide in and out as bone is penetrated to avoid applying excessive force to a gear assembly.
FIGS. 5A-5C illustrate one embodiment of a penetrator assembly 55 operable to penetrate a bone marrow, having a removable inner trocar 50 and an outer penetrator 52. Also shown in FIG. 5A is a penetrator shield 26 that may be used to shield penetrator assembly 55 from inadvertent engagement and also serves to preserve needle sterility. In some embodiments outer penetrator 52 may be a type of needle or cannula. FIG. 5B illustrates outer penetrator 52 may include a male connecting piece 56 operable to engage a complementary female connecting piece 54 of inner trocar 50. Adjacent to male connecting piece 56 is connecting piece, locking mechanism 58 that locks into position on female connecting piece 54. Alternatively outer penetrator may include a female connecting piece suitable to engage a complementary male connecting piece of an inner trocar. Luer lock attachment 57 is coupled to male connecting piece 56 for connection to an intravenous tubing or syringe after the outer penetrator is positioned in the bone marrow. Male connecting piece 56 and female connecting piece 54 may also be of the luer-lock type. Inner trocar 50 includes stylet 53 that keeps outer penetrator 52 from getting plugged with debris created during drilling. Stylet 53 acts in combination with cannula portion 51 of outer penetrator. Outer penetrator 52 may include flange 60 that abuts or interfaces the skin of an insertion site and may be used to stabilize a penetrator assembly at the time of insertion. Penetrator assembly 55 may include various types of connectors, such as connector 62 that may be used to connect penetrator assembly 55 to a powered drill. Connector 62 may be pentagonal as shown in FIGS. 5A and 5C.
FIG. 7F illustrates another embodiment of a release mechanism where O-ring 72 is included in trocar 98 as part of a connector. In this embodiment O-ring 72 is in the wall of receptacle 97, O-ring 72 is able to engage a lock and key connector, a pentagonal connector or any other suitable connector.
A method for providing access to the bone marrow includes using a powered drill, capable of reciprocal or rotational motion, to insert a penetrator assembly that includes an outer penetrator and an inner trocar into a hone marrow cavity. The powered drill is then released from the penetrator assembly and the inner trocar is grasped and removed from the outer penetrator. A connector present on the end of the outer penetrator, for example a luer lock connector, is then available for attachment to either an adapter, such as a right angle connector or directly to an intravenous tubing or syringe.
a penetrator assembly including an outer penetrator and an inner trocar, the outer penetrator having a flange configured to stabilize the penetrator assembly against an insertion site on skin of a patient and a cannula fixedly extending from the flange, the cannula operable to be inserted into bone marrow, and the inner trocar operable to penetrate bone marrow; and
a right angle connector removably couplable to the outer penetrator and operable to couple the outer penetrator to a source of intravenous fluid;
wherein the cannula of the outer penetrator is configured to removably receive a portion of the inner trocar, and
