    摘要: A core sampling biopsy device is compatible with use in a Magnetic Resonance Imaging (MRI) environment by being driven by either a pneumatic rotary motor or a piezoelectric drive motor. The core sampling biopsy device obtains a tissue sample, such as a breast tissue biopsy sample, for diagnostic or therapeutic purposes. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port. The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample.

    摘要: A medical pump with an improved continuity low flow delivery system and method for use with a pumping chamber, for example in a cassette, is disclosed. The pump includes a pump drive for exerting a force on the pumping chamber and a sensor for sensing the force/pressure exerted by the pump drive on the pumping chamber. The pump drive position sensor senses the position of the pump drive. The medical pump also includes a processing unit and a memory having a programming code adapted to calculate the rate of change of the sensed force/pressure values and determine whether the rate of change of the sensed force/pressure values meets a rate of change threshold. Once the rate of change threshold is met, the programming code is adapted to calculate a remaining pump drive travel value for determining how much farther the pump drive should travel before the end of an effective pump cycle. The programming code is further adapted to trigger one or more signals to drive the pump drive for the remainder of the effective pump cycle using the remaining pump drive travel value.

    摘要: A test tube (72, 72′) defines a test tube axis (75) and contains or supports an associated sample in an annular sampling region (12). At least two alignment bearings (80, 81, 81′, 82, 83, 110, 140, 142, 181, 182, 183, 184, 211, 212) engage the test tube at opposite sides of the annular sampling region along the test tube axis. At least one bias bearing (86, 86′, 87, 140, 142, 204) is radially spaced apart from the at least two alignment bearings and presses the test tube against the at least two alignment bearings to align a portion of the annular sampling region respective to the at least two alignment bearings. A motor (112) engages the test tube to selectively rotate the test tube.
