The catheter includes a distal end, a proximal end opposite the distal end, a lumen extending between the distal end and the proximal end, and a locking hub operably coupled to the proximal end. The locking hub includes a lumen segment of the lumen. In one implementation, self-biasing of the lumen segment places the lumen segment out of alignment with a rest of the lumen. Deflecting the lumen segment against the self-biasing of the lumen segment places the lumen segment in coaxial alignment with the rest of the lumen. In another implementation, self-biasing of the lumen segment reduces an inner diameter of the lumen segment and actuation of the locking hub expands the inner diameter.

    Abstract: Various surgical devices are provided having mechanisms for preventing premature actuation of a cutting mechanism. These devices generally include a handle having one or more actuators and an effector disposed at a distal end of the device and configured to grasp tissue. When the end effector is in an open position, a firing actuator can be positioned so that it cannot be actuated by a user. For example, the firing actuator can be obstructed by a shield or arm when the end effector is in the open position. In other embodiments, the firing actuator can be hidden in a recess formed in the closure actuator until the end effector is moved to the closed position. When the end effector is in the closed position, the firing actuator can be engaged to advance a cutting mechanism, thereby cutting the tissue grasped by the end effector.

  • Patent number: 10786269
    Abstract: A snare and retrieval device including a handle section, a cord section attached to the handle section, and a tip section removably attached to the cord section and spaced away from the handle section. Such a tip section is selectively detachable from the cord section while the cord section remains attached to the handle section. The tip section is detachable thereby allowing a surgeon to easily change the snare tip to a bigger or smaller size as necessary during the operation. A user can use one cord section for both removal of a polyp followed by retrieval of the polyp for further examination. This is done by changing the snare member to a retrieval member. The detachability of the tip section allows the device to replace at least two or more separate snare and retrieval devices, thereby reducing cost and time during the operation.

    Abstract: The preferred embodiment provides apparatus for ablating a vessel by generating heat within a vessel to cause blood clotting to occlude the vessel. The apparatus includes an electrically resistive element at the distal end of the apparatus, the resistive element being uncoated and therefore in bare form. An alternating current supply feeds electrical current through the resistive element to cause heating of the element and surrounding blood or tissue. The alternating current power supply preferably is balanced about a centre point so as to create a net sum of alternating pulses of zero. It has been found that the supply of alternating current to the resistive element reduces or eliminates corrosion of the resistive element in blood as the resistive element is heated. Use of conductive coatings for a sacrificial anode can be avoided.

  • Patent number: 9883962
    Abstract: An operating unit constituting a stent delivery system is provided with a first rotary roller having a first gear and a second rotary roller having a second gear. The first gear is meshed with a first tooth portion of a rack member and the second gear is meshed with a second tooth portion of the rack member. The first gear is formed to have a large diameter relative to the second gear and at the time of releasing a stent, after positioning a distal end of an outer tube body close to the stent through the rack member with the rotation of the first rotary roller of the operating unit, it is possible to move the outer tube body toward a proximal side at a lower speed than that in the previous state with the rotation of the second rotary roller.

  • Patent number: 9844407
    Abstract: A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.
