  • Oscillating syringe system
    Patent number: 11717274
    Abstract: A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The motor can oscillate back and forth to cause the needle to oscillate. Structures are described to permit one-handed operation of the device and automatic motor activation based on attaining a desired plunger position.

  • Rotatable syringe system
    Patent number: 11229424
    Abstract: A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The needle can have a sharp beveled tip which, in cooperation with rotation of the needle, harvests tissue in vivo via rotation rather than multiple “sticks” into the patient.
