  • Patent number: 10390978
    Abstract: Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding and at least one bridge. The continuous helical winding has a plurality of circumferential sections that circumscribe a longitudinal axis from a first end to a second end to define a tube. The circumferential sections are spaced apart along the axis. The at least one bridge is configured to connect one circumferential section to an axially-spaced adjacent circumferential section. The at least one bridge extends on a plane generally orthogonal with respect to the axis.

  • Patent number: 10342685
    Abstract: A stent includes a series of helical windings defining an outer circumference of a cylinder. The helical windings include a plurality of struts having straight portions connected by curved portions. The straight portions may be substantially aligned with a longitudinal axis of the stent when the stent is in a reduced state. A plurality of bridges connect adjacent windings. The bridges may be substantially orthogonal to the longitudinal axis of the stent in the reduced state. A plurality of radiopaque members extend from a terminal helical winding. The radiopaque members include an extension portion and an end portion. The extension portion may have a first width and the end portion may have a second width greater than the first width. The end portion may include an extreme end substantially orthogonal to the longitudinal axis of the stent.

  • Publication number: 20180310985
    Abstract: An endoscopic includes a handle, a tubular member, a control member, and an end effector assembly. The handle has a stationary member and a movable member. The movable member includes a constrained curved path for passage of the control member. The tubular member has an end coupled to the stationary member and a distal end rotatably coupled to the end effector assembly. The control member extends through the curved path, the tubular member, and is coupled to the end effector assembly. A knob is attached to the movable member and control member. Displacement of the movable member relative to the stationary member causes actuation of the end effector assembly, and rotation of the knob on the movable member causes the control member to rotate within both the constrained curved path and the tubular member, and results in rotation of the end effector assembly.

  • Publication number: 20170100267
    Abstract: Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding having interconnected struts joined at vertices, and having bridges connecting sections of the helical winding to each other. An annular ring can be provided at one or both ends of the helical winding, and the annular ring can have extensions extending to connect to the helical winding.

  • Patent number: 9566083
    Abstract: An endoscopic instrument includes an elongate hollow member, an actuator that moves axially through the hollow member, and first and second end effectors with respective tissue engaging edges. At least one of the end effectors is rotatably coupled to the hollow member adjacent its distal end. At least one of the end effectors includes a base supporting a resilient leaf-spring portion that includes a respective cutting edge. The resilient leaf-spring portion extends from the base in a cantilevered arrangement and generates a spring force acting on the respective cutting edge such that in a loaded state there is an automatic preload force imparted between the cutting edges of the end effectors to maintain a consistent and continuous mating force between the two opposed tissue engaging edges preferably over the complete range of rotational movement of the end effectors.

  • Patent number: 9566082
    Abstract: An endoscopic instrument includes a control wire having a push rod at its distal end and an end effector assembly having first and second effector elements such as scissors blades mounted on a clevis. The effector elements are operated by a cam-pin on the push rod riding in cam-slots defined in the effector elements. According to one aspect of the invention, the effector elements are symmetrically opened even when the push rod is canted relative to the clevis. According to another aspect of the invention, the effector elements can be rotated into a closed configuration that minimizes the distal dimension across the effector elements. In addition, the effector elements, when in the closed configuration, can rotate together to facilitate insertion of the end effector into an entry portion of an endoscope.

  • Patent number: 8690909
    Abstract: An endoscopic instrument includes a tubular member having a proximal end and a distal end, a clevis at the distal end of the tubular member, and an end effector assembly mounted on the clevis. A control member extends through the tubular member and includes a cam-pin coupled to the distal end thereof. The end effectors are controlled with a cam-pin and cam-slot arrangement, with the end effectors including the cam-slot and such cam-slot having a proximal end slot bilaterally widened to permit the cam-pin additional movement therein. When the cam-pin is retracted to move the end effectors into a closed positions and then further retracted into the bilaterally widened area, the end effectors can rotate together in the same direction to facilitate movement through a rigid bend in an endoscope.
