With Special Blade Or Retracting Surface Structure Patents (Class 600/210)
  • Patent number: 10426450
    Abstract: A retractor for use in surgical operations comprises a pair of blade assemblies. In operation, the blade assemblies are initially in a closed position to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The retractor is adapted to rotate a first blade about a first axis and a second blade about a second axis. The retractor is adapted to move the pair of blade assemblies apart along a third axis. The retractor is adapted to pivot the first blade about a fourth axis and the second blade about a fifth axis. In some embodiments, a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor is provided.

  • Patent number: 9757103
    Abstract: In a method for inserting an endoscopic device, a guide wire is punctured into a subject from outside the body. A tip portion of the wire is inserted into a first hollow organ. A tip-side portion of the inserted wire is projected into a lumen of a second hollow organ that communicates with the first via an opening, from the opening. An endoscopic device is inserted through a flexible endoscope and pushed into the second hollow organ. A tip portion of the device is locked onto the tip-side portion of the wire projecting into the second hollow organ. A portion of the wire outside the body of the subject is held and is tugged outside of the body. The tip portion of the device is thus pulled into the first hollow organ from the second, via the opening. Therefore, the endoscopic device can be led to the first hollow organ.

  • Patent number: 9687637
    Abstract: In general, the invention is directed to a technique for percutaneously introducing a stimulation lead into a target stimulation site via the epidural region proximate the spine of a patient. The process of introducing the stimulation lead may include the use of a hollow stimulation lead introducer, which comprises an elongated sheath and an elongated dilator. The dilator fits within the sheath and serves to widen a path through the epidural region for the introduction of a stimulation lead. At least a portion of the stimulation lead introducer has an oblong cross-section, allowing passage of stimulation leads such as paddle leads. The stimulation lead introducer may enter the epidural region proximate a spine of a patient via a guidewire. The stimulation lead introducer provides a path through the epidural region of a patient to a target stimulation site. A stimulation lead may travel through the path to reach the target stimulation site where it may provide therapy to the patient.

  • Patent number: 9254126
    Abstract: The present invention provides a non-rigid retractor for providing access to a surgical site, such as a patient's spine, during a surgical process. When used in spinal surgery, the non-rigid retractor allows a surgeon to operate on one or more spinal levels. The non-rigid retractor includes at least one flexible strap anchored at a first end to the spine or other internal body part at the surgical site. The body of the at least one flexible strap extends from a skin incision and is anchored at a second location external to the body to retract skin and muscle from the surgical site, allowing adequate visualization of the surgical site and providing access for implants and surgical instruments to pass through the retractor and into the surgical site.

  • Patent number: 9186268
    Abstract: A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

  • Patent number: 9107648
    Abstract: An intracorporeal surgical tissue retractor is provided having an anchor selectively deployable in a first tissue not to be retracted and a grasper selectively deployable on a second tissue to be retracted. A longitudinally selectively movable support is threadable through the anchor and attached at a substantially distal end of the movable support to the grasper. A deployment user interface is couplable to the movable support and has a proximal end manipulable by a user extracorporeally and a distal end releasably attachable to both the anchor and the grasper, adapted to intracorporeally deploy the anchor into the first tissue and the grasper onto the second tissue. The user interface includes a first actuator having an anchor positioning tool enabling selective deployment of the anchor in the first tissue, and a second actuator enabling selective opening and closing of the jaws of the grasper.

  • Patent number: 9095301
    Abstract: A minimal incision maximal access system allows for maximum desirable work space exposure within the incision along with maximum access to the operative field utilizing a minimum incision as small as the width of the working tube. Instead of multiple insertions of dilating tubes the design is a streamlined single entry device to avoid repetitive skin surface entry. The system offers the capability to expand to optimum exposure size for the surgery utilizing retractors depending from a bi-hinged frame having internal or external controls to control the angle and separation of the retractors. Interchangeable retractor blades can be attached to the frame. Both retractor blades are independently controlled as to displacement and angle.

  • Patent number: 9033874
    Abstract: A surgical retractor comprising a retractor body having a site portion and handle portion, and an impactor body on the retractor body. The impactor body is positioned and configured for use in impacting the site portion of the surgical site. An impaction axis of the impaction body is preferably substantially aligned with an axis of the site portion of the impactor body. The impactor body is preferably attached to the retractor body at a junction between the site portion and the handle portion of the retractor body. In one embodiment, the impactor portion is configured to selectively mate with an impactor extension member to thereby optionally receive direct impaction on the impactor portion or indirect impaction through the impactor extension member.

  • Publication number: 20150094533
    Abstract: The foregoing application describes a system and method of performing a minimally invasive surgical operation. More specifically, the invention involves the use of disposable cannula and slender dilators of variable lengths, which incorporate a source of illumination to carry light to a surgical site and video capabilities for capturing and displaying images from a CMOS or CCD camera device. According to one embodiment, fiber optics run semi-circumferentially or along walls of the cannula/dilator and terminate at about a centimeter from the distal end of the cannula/dilator, thereby preventing illumination from “bottoming out” at the floor of the incision. According to one alternate embodiment, the light fibers may be fashioned in an annulus around one or more camera chips to provide illumination and video of the surgical site.

  • Patent number: 8992558
    Abstract: A minimally invasive dilation device includes a plurality of rigid arms radially arrayed about a center and a dilating member positioned between the arms. A stylus may occupy the center. An outer flexible sleeve may be circumferentially secured to the arms, lying within or without the plurality of arms. An inner mesh may surround the stylus and dilating member. The device may be introduced into tissue toward a targeted area, while in a closed configuration. The dilating member may be a balloon, wherein upon inflation of the balloon, the arms are pushed radially outward, expanding the device and dilating the surrounding tissue. The dilating member may be a tube, wherein upon insertion of the tube, the arms are pushed radially outward. A cannula may be inserted inside the plurality of arms to keep the arms in an open configuration, and the dilating member may be withdrawn, providing an open passageway through the device to the targeted area. The device may be used with a neural monitoring system.
