Abstract: Apparatus and methods provided to remove biopsy specimens from bone and/or associated bone marrow. A powered driver may rotate a biopsy needle at an optimum speed to obtain the biopsy specimen. A thread or a groove may be disposed on interior portions of the biopsy needle. The thread or groove may engage a biopsy specimen and enhance removal of a bone marrow core from cancellous bone. Manufacturing procedures are provided for bonding a single helical thread with interior portions of the biopsy needle. The apparatus may also include a biopsy sample ejector and/or ejector funnel. A biopsy needle set may include a cannula and a trocar with respective tips having optimum configurations, dimensions and/or orientations relative to each other to optimize penetration of a bone and/or bone marrow with minimum patient trauma and enhanced reliability of obtaining a biopsy specimen.

Abstract: An apparatus for removing portions of bone marrow from a bone is provided. The apparatus includes a housing and a hollow drive shaft operable to engage a gear assembly. The hollow drive shaft includes a first end operable to penetrate the bone and a second end operable to allow retrieval of portions of bone and bone marrow. The apparatus also includes a removable trocar. The removable trocar includes an inner channel operable to convey portions of bone and bone marrow. The gear assembly is able to engage and rotate the hollow drive shaft. A motor operable to drive the hollow drive shaft into the bone marrow by rotation of the hollow drive shaft and a power supply and associated circuitry operable to power the motor are also included.

Abstract: An apparatus and method for penetrating bone marrow is provided. The apparatus may include a housing such as a handheld body, a penetrator assembly, a connector that releasably attaches the penetrator assembly to a drill shaft, a gear mechanism, a motor and a power supply and associated circuitry operable to power the motor. The penetrator assembly may include a removable inner trocar and an outer penetrator or needle. It may also include a grooved trocar that allows bone chips to be expelled as the apparatus is inserted into bone marrow. Various connectors are provided to attach the penetrator assembly to the drill shaft.

Abstract: An improvement to computing systems is introduced that allows a hardware controller to be configured to time partition a shared system resource among multiple processing elements, according to one embodiment. For example, a memory controller may partition shared memory and may include processor-accessible registers for configuring and storing a rate of resource budget replenishment (e.g. size of a repeating arbitration window), a time budget allocated among each entity that shares the resource, and a selection of a hard or soft partitioning policy (i.e. whether to utilize slack bandwidth). An additional feature that may be incorporated in a main-memory-access time-partitioning application is an accounting policy to ensure that cache write-backs prompted by snoop transactions are charged to the data requester rather than to the responder. Additionally, an arbiter may prioritize requests from particular requesting entities.
