    Abstract: Liquid is ejected in a pulse-like manner from a nozzle provided at the distal end of a liquid ejection pipe. When the liquid is ejected, moving speed of the nozzle is detected. A driving frequency of a piezoelectric element is increased when the moving speed increase. The driving frequency is reduced when the moving speed decreases. Consequently, it is possible to prevent the number of times the liquid is ejected per unit length from changing according to the moving speed of the nozzle. Therefore, it is possible to excise a biological tissue at stable excision depth.

  • Patent number: 9005136
    Abstract: A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable hand piece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. External vacuum holes along the outer cannula (probe) that communicate with a vacuum and cutter lumen withdraw bodily fluids while a hemostatic disk-shaped ring pad around the probe applies compression to an external hole in the skin and absorbs fluids.

  • Patent number: 8944069
    Abstract: Medical devices, medical procedure trays, kits and related methods are provided for use to perform medical procedures that require access to the interior of a bone. The devices, trays and methods allow multiple use of non-sterile medical devices with sterile medical devices for performing medical procedures requiring sterile conditions. A coupler assembly, capable of releasably attaching to a non-sterile medical device at one end and releasably attaching to one or more sterile medical devices at another end, and further comprising a containment bag which allows maintaining sterility of a non-sterile medical device which may be used in conjunction with sterile medical devices and procedures. The devices, trays, kits and methods enable the performance of multiple medical procedures with a single insertion into bone. For example, a vertebral procedure such as a vertebroplasty may be performed along with biopsy and/or bone marrow aspiration procedures, thereby reducing patient trauma and costs.

  • Patent number: 8915864
    Abstract: The invention is directed to a system and method for separating and collecting one or more tissue specimens from a target site within a patient and flushing the specimen to remove blood, debris and the like before the specimen is removed from the biopsy device. The flow of flushing fluid to the tissue collector is preferably controlled to coincide with delivery of one or more specimens to the collecting tray or basket of the device or after the receipt of the specimen within the tissue collector to ensure that the fluid is applied to a fresh specimen. The tissue tray or basket within the tissue collector has an open or foraminous portion to facilitate removal of fluid, such as the applied fluid and blood, and other debris from the tissue specimens on the tray. Vacuum is provided within the tissue collector, preferably under the tray to remove fluid and debris from the collector interior.

  • Patent number: 8911381
    Abstract: A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.

  • Patent number: 8858465
    Abstract: 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.
