  • Patent number: 10188833
    Abstract: An endovascular guide catheter includes a guide tube and a handle. The flexible guide tube has a distal end portion configured to deflect via actuation of a pull wire. The handle is coupled to the guide tube and comprises a steering assembly configured to actuate the pull wire to deflect the distal end portion of the guide tube. The steering assembly can comprise a stationary rack, a gear, a reel, and a slider. The gear engages the rack and the reel is coupled to and configured to rotate with the gear.

    Abstract: A surgical instrument includes a shaft assembly, a handle assembly, and a latch system configured to operatively couple the shaft and handle assemblies. The latch system includes shaft and a handle lock members respectively connected to the shaft and handle assemblies for inhibiting operative uncoupling of the shaft and handle assemblies. The latch member has a cam surface and a latch member. The latch member is configured to selectively move from a locked position to a released position such that movement of the latch member causes the shaft and handle lock members to disengage and uncouple the shaft and handle assemblies. The latch member is further configured to selectively move from the released position to a removal position such that further movement of the latch member causes the cam surface of the latch member to engage the cam base and urge the shaft assembly in a removal direction.

  • 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.
