  • Patent number: 10166084
    Abstract: A tool for inserting a marker into tissue at a biopsy site includes an elongate plunger having a blind bore. A plunger rod has a proximal end received within and secured to the blind bore so that the plunger rod moves conjointly with the plunger and a spring is secured to the distal end of the plunger rod. A cannula has a lumen that receives a distal end of the plunger rod and a crimp is formed in the cannula near its distal end. The cannula has a side exit port where a marker is ejected from the lumen. A ramp is formed in communication with the side exit port and the ramp has a preselected slope that controls the angle at which the marker is ejected. The marker is ejected from the side exit port into tissue when the spring unloads abruptly as the marker clears the crimp.

  • Patent number: 10159845
    Abstract: The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package that is suitable for implantation in living tissue, for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a plated rivet-shaped connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.

  • Patent number: 10165660
    Abstract: A low-voltage controller (LVC) is configured to utilize a low-voltage signal to operate a high-voltage load, such as, for example, a lamp. The LVC is configured to receive a low-voltage step signal at a switch input. The LVC has a line input for connection to a source of power at a line voltage and a load output for connection to a load, and a dimmer for setting an intensity of the load. Subsequent step signals alter the intensity of the load. A method for low-voltage control of a lamp is provided. A method includes the steps of receiving a first switch signal at a switch input of an LVC; setting the lamp to a first intensity; receiving a second switch signal at the switch input; and setting the lamp to a second intensity.

  • Patent number: 10123820
    Abstract: A biopsy system with a grid plate used as either a lateral or medial compression plate of a localization fixture used with a breast coil includes a rotatable guide cube that may be inserted into a desired rectangular recess in the grid plate after rotating to position a selected guide hole in the desired spatial orientation. Versions of a guide cube include those rotatable in two axes to provide additional hole positions, angled holes, enlarged circular holes that function with a rotating guide to support a noncircular biopsy instrument cannula (e.g., trocar/sleeve combination, core biopsy probe of a biopsy device) for rotation.

  • Patent number: RE47148
    Abstract: A biopsy device includes a body, a needle, and a cutter. A motor is operable to both move the cutter relative to the needle and actuate a needle firing assembly to retract and fire the needle relative to the body. The biopsy device also includes a needle rotation assembly that is configured to substantially prevent rotation of the needle about the longitudinal axis when the needle is in a proximal position yet permit rotation of the needle about the longitudinal axis when the needle is in a distal position. A valve assembly of the biopsy device includes a slider that selectively couples a secondary lumen in the needle with either atmospheric air or saline based on the longitudinal position of the slider. The cutter passes through the slider.
