Abstract
A device and method for dampening a biopsy device externally or internally. One variation of the external dampening device includes a flexible sleeve provided to cover external surfaces of the biopsy device. The dampening device may also include a device to cover the entire device externally, wherein only a needle portion is exposed. Further in another aspect, a spring constant or spring property of the springs used in the biopsy device may be altered to decrease the noise emitted from the biopsy device. A device and method is also disclosed for dampening a biopsy device internally using an elastic damper at the end portions of any springs that may be used in the biopsy device or at the end of a stroke of certain movable portions inside the biopsy device.
