  • Patent number: 10349970
    Abstract: A medical/surgical device for performing tissue resection can include an endoscope with proximal and distal ends, defining working channels, and a snare assembly located in one of the working channels. The working channel may include a bend near the distal end and towards the outward radial wall of the endoscope. The snare assembly may include a snare loop and an actuation element imparted with the pre-formed angular bends and an actuation control handle. The bends of the actuation element and the working channel may be the same. The rotational manipulation of the actuation element may synchronize the pre-formed bend of the actuation element with the bend of the working channel to concentrically (or otherwise) align the deployed snare loop with the endoscope or endoscope attachments.

  • Patent number: 10335141
    Abstract: A suturing device, and methods for suturing various sizes of apertures in tissues, are presented. The suturing device has a body with at least one or more adjustable arms that are coupled with catch targets. The arms are coupled with needle guides such that movements of the arms orient the needle guides to direct the needles towards the catch targets. The catch targets are coupled with sutures, such that when the needles reach the targets, they capture and pull the sutures back to the body. By changing the angles at which the arms extend from the body, the catch targets are moved closer to, or farther from, the body, and the suture device is readily configured to suture various sizes of apertures.

  • Patent number: 10335275
    Abstract: Methods related to delivery of various heart valve implants are described. The implant may be delivered using an ultrasound imaging delivery system. The ultrasound imaging delivery system may be used to deliver a variety of different devices, including mitral valve reshaping devices, mitral valve replacement valves, and others. A deployment catheter carrying an implant having a tissue anchor is advanced to a deployment site in a heart. An imaging element is positioned adjacent the implant and a relationship between the tissue anchor and an anatomical landmark in the heart is visualized. The implant is then attached by driving the tissue anchor into tissue in the heart.

  • Patent number: 10327896
    Abstract: An expandable introducer sheath for passage of implant delivery catheters, such as catheters for delivery of prosthetic heart valves. The expandable sheath balances the amounts, shapes and positions of various stiff and elastic structures in the sheath to selectively program the expandability and buckling stiffness of the sheath. The expandable sheath can include, for example, an expandable tubular layer that includes alternating stiff and elastic wall portions of a single radial thickness. The combination of stiff and elastic wall portions allow for torque and push strength to advance the expandable sheath while at the same time accommodating temporary expansion. The expandable sheath can also be reinforced with a tubular layer of braided fibers or a stent structure for additional strength. Other embodiments include selective use of slots or gaps at the distal end of a stiff wall portion to enhance expandability and distribute strain.

  • Patent number: 10271836
    Abstract: An endoscopic stitching device includes an actuation shaft, a tool assembly, and a drive assembly. The tool assembly includes a suture needle and a pair of jaws transitionable between open and closed positions. Each jaw includes a needle engaging blade slidably supported thereon. Each needle engaging blade is transitionable between an extended position in which the needle engaging blade engages the suture needle and a retracted position in which the needle engaging blade is disengaged from the suture needle. The drive assembly includes first, second, and third electrical actuators. The first actuator is operatively coupled with the actuation shaft to cause axial displacement of the actuation shaft. The axial displacement of the actuation shaft causes opening and closing of the pair of jaws. The second and third actuators are operatively coupled with the needle engaging blades to provide axial displacement of the needle engaging blades.

  • Patent number: 10258463
    Abstract: A novel phakic intraocular lens implantation without viscoelastics and an instrument thereof. The special designed instrument is employed to achieve a purpose of maintaining an anterior chamber only with a perfusion liquid in the surgery, so as to get rid of the influence of the viscoelastics completely. The viscoelastics are not used, so that there is no need to inject the viscoelastics or remove the viscoelastics as in traditional methods, the surgery time is shortened such that total time of surgical procedures from incision construction to incision hydration can be reduced to only 1˜3 minutes, and viscoelastic-related complications, such as postoperative high intraocular pressure and lens opacity, are completely avoided.
