  • Patent number: 10786320
    Abstract: A surgical tool includes a drive housing having an input shaft arranged therein for rotation, an elongate shaft that extends from the drive housing, and an end effector operatively coupled to a distal end of the elongate shaft. A cable band is coupled to the input shaft and operatively couples the input shaft to a drive cable that extends to the end effector. Rotation of the input drive correspondingly moves the cable band and thereby controls longitudinal movement of the drive cable to articulate the end effector.

  • Patent number: 9833595
    Abstract: An improved bi-directional steerable catheter is provided. The catheter generally comprises a catheter body, tip section and control handle. The catheter further comprises first and second puller wires extending from the control handle, through the catheter body and into the tip section. The control handle has deflection means for each puller wire that include a gear, and a carrier to which the proximal end of a puller wire is anchored. The gear is rotatably coupled to a lever controlled by an operator and the gear engages the carrier such that rotation of the gear by the lever results in longitudinal movement of the carrier, which results in deflection of the tip section.

  • Patent number: 9694158
    Abstract: A torque for controlling the advancement and rotation of a right heart catheter during a right heart catheterization procedure. The torque has a casing with a cavity for receiving a core, and a lumen for receiving the right heart catheter. A gripper is disposed within the core to tightly grip the right heart catheter. The core has a plurality of threads that engage teeth of a handle. The handle is attached to the casing at an axis and rotates about the axis during use. The core has an elongated spiraled recess which is engaged by a guide pin attached to the casing and extending within the cavity. When the handle is rotated, the teeth of the handle engage the threads to rotate the core, and the guide pin engages the elongated spiraled recess to move the core laterally, thereby advancing and rotating the right heart catheter.

  • Patent number: 9694167
    Abstract: A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.

  • Patent number: 9586029
    Abstract: A guidewire assembly having selectively adjustable stiffness and tip curvature includes a hollow guidewire having a distal portion terminating at a distal tip, a curvature-modifying element anchored to the distal tip, and a stiffness-modifying element displaceable within the hollow guidewire towards and away from the distal tip so as to vary a stiffness of the distal portion. The stiffness-modifying element and the curvature-modifying element are frictionally linked such that movement of the stiffness-modifying element from a current position over a first range of motion causes corresponding displacement of the curvature-modifying element, thereby modifying a state of curvature of at least part of the distal portion of the guidewire. Movement of the stiffness-modifying element beyond the first range of motion displaces the stiffness-modifying element relative to the curvature-modifying element.
