Abstract: A single needle assembly enables to obtain bone marrow aspiration and trephine biopsy specimens from the right or left posterior ilium at the same time and through the same puncture site while also maintaining the specimen quality. The operator obtains a firm grip on the single needle assembly using a T-shaped ergonomically designed handle. The distal end of the needle comprises one or more holes between the one or more external serrations and one or more sharp cutting facets. The proximal end of the trocar comprises a plastic knob wherein at the top of the knob is a connector further comprising external threads to attach a syringe or a small plastic Luer-lock cap. An insertion aid enables the operator to align the mouth of the needle and a pusher rod to propel a trephine biopsy specimen from the lumen of the needle.

Abstract: A biopsy needle consisting of a main portion, a linking portion and a front end portion wherein the main portion has a first bore of uniform circular cross-section, the front end portion has a smaller second bore of uniform circular cross-section and the linking portion has a shoulder between the first bore and the second bore. The outer surface of the linking portion is tapered. The open front end has multiple projecting teeth which serve to cut. There may also be serrations on the outer surface of both the front end portion and the linking portion. The biopsy needle has slits or holes to facilitate the expansion of the captured biopsy specimen and to inject cement for bone support. The needle assembly has a non-slip grip on multiple surfaces and pins hold components in place during rotation of the assembly.

Abstract: A method and apparatus for injecting supportive and therapeutic agents into bone marrow. During conventional chemotherapy for leukemia, lymphoma, multiple myeloma and other bone related diseases, chemotherapeutic agents are typically injected intravenously. Intravenous injection, however, as a method of chemotherapy, has a number of potential disadvantages. By injecting therapeutic agents directly into the bone marrow using the present method and apparatus, these disadvantages can be avoided. A stronger needle with a shorter and sharper tip, when compared to a conventional intravenous or sternal puncture needle, designed to optimally administer therapeutic agents into bone marrow without causing injury is disclosed. The method includes injecting therapeutic agents into large reservoirs of bone marrow in accessible areas such as ilium and sternum is most likely to have a significant effect in treating bone marrow diseases.

Abstract: An injection port system for placement in or on an individual includes a first port (55) defining a first injection chamber (58) with a septum (59), and a tubular securing device (38) for securing said first injection chamber to bone (52) of the individual. A needle inserted through the septum (59) enables material to be injected into or removed from the bone marrow (60), for example injecting chemotherapeutic agents, or stem cells, or withdrawing bone marrow for analysis. The injection port system (50) also comprises a second port (62) defining a second injection chamber (65) with a septum (66), the first port (55) being mechanically connected to the second port (62). The second port (62) is linked by a catheter (68) to a blood vessel, so that therapeutic fluids can be directly supplied to the blood system, and blood samples can be taken for monitoring.
