20120265095 | BIOPSY DEVICE WITH MOTORIZED NEEDLE FIRING - A biopsy device comprises a needle, a body portion, and a needle firing assembly. The needle firing assembly is operable to fire the needle distally relative to the body portion. The needle firing assembly includes two translating members, a resilient member, and a motor. The motor is operable to selectively move the first translating member distally and proximally. The second translating member is secured relative to the needle such that the needle and the second translating member translate unitarily. The resilient member compresses as the first translating member is moved distally toward the second translating member. The first translating member is then secured to the second translating and the translating members are moved proximally while holding the resilient member in the compressed state. The second translating member is released from the first translating member when they reach a proximal position, which allows the resilient member to fire the needle distally. | 10-18-2012 |

20130218047 | BIOPSY DEVICE VALVE ASSEMBLY - A biopsy assembly includes a biopsy device, a vacuum source, and a valve assembly. The biopsy device includes a body, a needle extending distally from the body, and a cutter translatable relative to the needle. The needle includes a lateral tissue receiving aperture. The cutter is translatable to selectively close the lateral tissue receiving aperture of the needle. The valve assembly is in fluid communication with the needle. The valve assembly includes a first valve, a second valve, and tubular member. Each of the first valve and the second valve selectively provide atmospheric venting or vacuum to the needle. The tubular member is coupled with the vacuum source and includes a first and second connector extending transversely from the tubular member. The first and second connectors couple to the first and second valves to provide vacuum to the first and second valves. | 08-22-2013 |
20140039343 | BIOPSY SYSTEM - A biopsy system includes various features. A tissue sample holder kit of the system comprises a rotatable member with chambers configured to receive tissue receiving features of a tissue sample tray. A biopsy device of the system includes user input features and user feedback features disposed on a body. A user interface of the system includes a graphical representation of a tissues ample holder. A biopsy site marker applier of the system includes markings associated with different biopsy device configurations. The biopsy system may undergo a multi-step initialization process. In operation, the biopsy system may execute pneumatic control algorithms including the use of vacuum, saline, and atmospheric air. | 02-06-2014 |
20140275999 | BIOPSY DEVICE - A biopsy device includes a probe, a holster, and a tissue sample holder for collecting tissue samples. The probe includes a needle and a hollow cutter. The tissue sample holder includes a housing having a plurality of chambers that are configured to receive a plurality of strips connected by at least one flexible member. The flexible member is configured to permit the strips to pivot relative to each other such that the strips can shift between a flat configuration and a arcuate configuration. The tissue sample holder is rotatable to successively index each chamber to the cutter lumen such that tissue samples may be collected in the strips. The strips may be removed from the tissue sample holder and placed in a tissue sample holder container for imaging of tissue samples. | 09-18-2014 |
