  • Patent number: 10842524
    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: 10814096
    Abstract: A catheter assembly provided with a wire arranged therein to form a loop extending from near the effective end of the catheter for bypassing an occlusion in a vein/artery. This loop consists of two wire ends, one of which wire ends extends through the catheter to the control end thereof, while the other wire end is attached thereto, in close proximity to the effective end of the catheter. By varying the relative position of the loop wire end extending from the control end and the control end, the size of the loop and the pushability thereof at the effective end of the catheter can be determined. In this manner, the occlusion can be removed with precise control by the physician using two hands. In addition, the catheter is formed not only for the loop wire end extending through the catheter, but also for incorporating a guide wire and/or for contrast fluids.

  • 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.

  • Patent number: 10682172
    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: 9408657
    Abstract: Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure and temperature sensing elements which may allow for control of the pressure and temperature within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled, room temperature, or warmed fluid such as water may then be used to rapidly terminate the treatment session.
