摘要： A method for operating a medical device includes measuring a configuration of a tube, receiving a desired configuration of the tube, determining an actuation input to bend the tube to the desired configuration, and transmitting the actuation input to at least one force transmission element that is actuatable to alter the tube between a flexible state and a stiffened state. Altering the tube from the flexible state to the stiffened state includes simultaneously applying first and second tension forces to first and second force transmission elements, respectively, to compress and shorten a length of the tube. The method further includes receiving a first command to place the tube in the flexible state, reducing longitudinal compression on the tube in response to the first command, receiving a second command to place the tube in the stiffened state, and longitudinally compressing the tube in response to the second command.

摘要： A transapical removal device that can be deployed in a catheter procedure to capture for removal or alteration a mitral valve clip or heart tissue, such as the anterior leaflet of the mitral valve, and methods of use are disclosed. The removal device includes a delivery catheter configured to be deployed near a mitral valve using a guide catheter. The delivery catheter has a snare head at the distal end, which assumes a collapsed state during movement of the delivery catheter through the guide catheter and deployed state for capturing a mitral valve clip or anterior leaflet. The snare head has one or more ablation delivery catheters configured to ablate tissue surrounding the pre-positioned mitral valve clip or anterior leaflet. In some arrangements within the scope of the present disclosure, the removal device includes a deployment mechanism for deploying a new transcatheter valve into the mitral valve.

摘要： A control unit that includes a braking system for fixing the position of an endoscope tip is provided. The control system includes an up-down control knob and a right-left control knob. The brakes are engaged by rotating the control knob itself counter-clockwise from a free wheeling position. After the brakes have been engaged, a sufficient amount of force applied to the control knobs will move the endoscope tip slightly in the corresponding direction, allowing for fine tuning of tip position after braking.

摘要： A device includes a first mechanism having a surface and a helical slot in the surface, a second mechanism having a periphery and an axial slot in the periphery, and an insert comprising a pin. The second mechanism is located within the first mechanism. The insert is located within the second mechanism. The pin extends from the insert through the axial slot of the second mechanism and into the helical slot of the first mechanism. The insert is configured to couple to an instrument. In some embodiments, the insert is configured to move the instrument in a degree of freedom in response to the second mechanism being held stationary and the first mechanism being rotated. In some embodiments, the degree of freedom is an insertion and retraction degree of freedom.

摘要： A handle for a medical device includes a handle body and a knob that is rotatable with respect to the handle body. A first gear is associated with the knob. A slide assembly is housed within the handle body or the knob. The slide assembly includes a first lead screw. A second gear is associated with the slide assembly. A third gear is housed within the handle body or the knob and is coupled between the first gear and the second gear. Rotation of the knob drives rotation of the first gear, rotation of the first gear drives rotation of the third gear, rotation of the third gear drives rotation of the second gear, and rotation of the second gear drives rotation of the lead screw.

摘要： A wire driver for driving a wire or pin into living tissue includes a rotating drive shaft, a collet, and a wedge. The collet is held fast to the drive shaft and has a plurality of feet radially moveable relative for grasping the wire or pin. Each foot has an outwardly located curved ankle surface with a concave or convex profile. The wedge is disposed over the collet and is at least partly inside the bore of the drive shaft. The wedge rotates with the drive shaft and has a tapered inner surface in selective engagement with the curved ankle surfaces. The wedge is moveable longitudinally relative to the collet feet to bear against the feet and cause the feet to grasp the wire or pin. The wedge has a release position in which the wedge is spaced from the collet feet, releasing the wire or pin.

摘要： A surgical system comprises a manipulator arm, configured to secure to a base, and an actuator assembly. The actuator assembly includes an instrument mounting bracket and a plurality of actuator disks supported on a first end of the instrument mounting bracket. The surgical system also includes a surgical instrument including a plurality of interface disks supported on a face of the surgical instrument. The plurality of interface disks is configured to mate with the plurality of actuator disks. The instrument also includes an attachment mechanism configured to removably attach the surgical instrument to the actuator assembly and an instrument body tube extending from the face of the surgical instrument. The instrument body tube is capable of passing by or passing through the instrument mounting bracket when the surgical instrument is attached to the instrument mounting bracket.
