  • Patent number: 10449334
    Abstract: The present invention relates to methods of transvascular retrograde access placement and to devices that facilitate these methods. For purposes of the present invention, transvascular retrograde access placement generally comprises the insertion of a vascular catheter into a central blood vessel through the puncturing of the central blood vessel from the inside of the central blood vessel with a needle or other similarly configured device, or a needle-tipped guidewire of the present invention, and exiting that needle from the patient through the skin rather than the traditional approach of inserting a needle from the outside of the skin surface to the inside of a blood vessel.

  • Patent number: 10099034
    Abstract: An insertion device for delivering media inside a patient includes an outer guide tube having a side port. An inner guide tube is nested within the outer guide tube and movable axially within the outer guide tube. The inner guide tube includes a deflector at an end within the outer guide tube. The device also includes a catheter nested within the inner guide tube and movable axially within the inner guide tube. The deflector of the inner guide tube is positionable such that it deflects the dispensing end of the catheter outward through the opening in the outer guide tube when the catheter is advanced axially within the inner guide tube. A therapeutic delivery cannula may be nested within the catheter, such that the deflected end of the catheter determines the direction of travel of the therapeutic delivery cannula into patient tissue when the cannula emerges from the catheter.

  • Patent number: 8668638
    Abstract: In a robotic endoscope system, the orientation of a captured camera view at a distal tip of a robotic endoscope and displayed on a screen viewable by an operator of the endoscope is automatically maintained at a roll orientation associated with a setpoint so as not to disorient the operator as the endoscope is moved, flexed and its tip turned in different orientations. A processor generates a current commanded state of the tip from operator input and modifies it to maintain the setpoint roll orientation. To generate the modified current commanded state, the current commanded roll position and velocity are constrained to be a modified current commanded roll position and velocity that have been modified according to a roll angular adjustment indicated by a prior process period commanded state of the tip and the setpoint. The processor then commands the robotic endoscope to be driven to the modified commanded state.

    Abstract: An insertion apparatus includes insertion unit, a rotation drive mechanism, a first rotation member which is arranged inside the insertion unit and rotates by the rotation drive mechanism, a second rotation member which is attached to an outer peripheral surface of the insertion unit and is adjacent to the first rotation member, and a helical rotation member which is rotatable in accordance with rotation of the second rotation member. The insertion apparatus include a magnetic force generation mechanism which generates a magnetic force that enables the first rotation member and the second rotation member to be attracted to and coupled and enables the second rotation member to rotate follow rotation of first rotation member. The magnetic force generation mechanism is arranged at a tubular end portion of the first rotation member and a tubular end portion of the second rotation member adjacent to the end portion.

  • Patent number: 8647262
    Abstract: A deflectable tip videoarthroscope of 5.4 mm diameter or smaller, comprising a miniaturized chip-in-tip CCD with four-way angulations mounted on the distal end of the arthroscope. The deflectable tip videoarthroscope may be provided with a replaceable distal window made of a thin material (such as polycarbonate or acrylic) or a glass (sapphire or other) with very high light transmission properties, connected to a sheathing system that is disposable or limited-reusable, which could be discarded if a shaver burr or ablation probe contacts the lens. This design protects the distal window of the videoarthroscope during use and reduces scope repair costs and system down-time. The deflectable tip videoarthroscope may additionally include a steering wheel, which allows 360 degree rotation of the instrument during arthroscopic procedures. The videoarthroscope may further include an irrigation channel or a wireless imager control system.

    Abstract: An endoscopic instrument includes a housing having shaft. The shaft includes an articulating section disposed thereon. An end effector assembly operatively connects to a distal end of the shaft and is configured to treat tissue. A plurality of tendons operably couples to the articulating section and is translatable along a longitudinal axis to effect articulation of the shaft about the articulating section. Each of the tendons includes a respective locking ferrule disposed thereon. A locking catheter is disposed within the shaft and between the plurality of tendons to selectively engage each respective locking ferrule. The locking catheter is rotatable within the shaft from a first position to allow articulation of the shaft about the articulating section, to a second position to prevent articulation of the shaft.

    Abstract: An endoscope includes a second bending drive mechanism. The second bending drive mechanism passively bends the second bending portion in accordance with external force when the drive force is not transmitted to the first bending portion. The second bending drive mechanism bends the second bending portion in a predetermined direction in a case that the second bending portion has received external force in the predetermined direction, and generates force against the external force in a direction different from the predetermined direction in the second bending portion in a case that the second bending portion has received the external force in the different direction while the drive force to bend the first bending portion in the predetermined direction has been transmitted to the first bending portion.

  • Patent number: 8475362
    Abstract: Provided is a surgical apparatus for transanal endoscopic microsurgery (TEM) in which a thin and long endoscope and surgical instruments are inserted through a natural orifice of a human body and the endoscope and surgical instruments are conveyed to the operation area in the body to perform the operation area in the body. According to the surgical apparatus for TEM, a rotation function is added to a barrel of the surgical apparatus for TEM to enable manual rotation of the barrel to a required extent and adjustment of an operation area, without separation of the surgical apparatus for TEM from a fixing frame during an operation. In addition, since the endoscope is disposed outside the barrel, it is possible to reduce the outer diameter of the barrel and uniformly maintain a visual direction of the endoscope even when the barrel is rotated. Further, since the rotation function is added to both the barrel and the surgical instrument insertion hole, more convenient operation is possible.
