  • Patent number: 9655506
    Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

  • Patent number: 9649138
    Abstract: A spinal facet bone screw and minimally invasive surgical method of implanting a facet screw to stabilize the spine are provided. The facet screw includes an elongated body portion having a head, a threaded portion and a distal threadless portion. A pair of flutes formed in the elongated body extends from the distal end across the threadless portion and into the distal end of the threaded portion. The flute creates a self-tapping cutting surface that includes a heel edge that is curved with respect to the outer surface. The method of implantation comprises making a minimally invasive incision on the side of the midline contralateral to the target facet joint and delivering the screw across the interspinous process using the adjacent spinous processes as guideposts. The facet screw system fixes juxtaposed facet articular processes to enhance spinal fusion and stability and the method provides for accurate, repeatable and easy implantation.

  • Patent number: 9642653
    Abstract: A minimally invasive spinous process fixation system includes dual rigid spinous clamps, each configured to articulate axially along a cylindrical shaft, and together configured to enclose and clamp around the adjacent or superior spinous process by means of opposing and swiveling spherical contact heads with spiked spinous contact faces. The spinous clamps are lockable when desired compression is achieved. A pedicle clamp has right and left clamp bodies for enveloping pre-existing pedicle rods. Each of the right and left clamp bodies includes upper and lower rigid metal plates supporting medial and lateral swivel cups. The upper and lower medial swivel cups engage and clamp about a connecting rod extending from the spinous clamp, and the upper and lower lateral swivel cups engage and clamp about one of the pedicle rods. A channel through the upper and lower metal plates accepts a locking screw to simultaneously tighten and fix the swivel cups in place about the connecting rod and the pedicle rod.

  • Patent number: 9622735
    Abstract: A surgical access system for accessing a surgical target site within a spine includes a retractor and an elongated element. The refractor has a closed configuration defining a lumen with an internal circumference, and an open configuration in which the internal circumference, at least at the distal end of the retractor, is enlarged relative to said closed configuration. The open configuration creates and maintains an operative corridor to said target site. The elongated element is releasably coupled to an interior wall of the retractor and has an extension extending distal of the distal end of the retractor into the surgical target site. When coupled to the retractor, the elongated element covers a body structure at the target site without blocking access to the operative corridor.

  • Patent number: 9610110
    Abstract: The present invention relates in certain embodiments to medical devices for treating vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the flow of bone cement into the interior of a vertebra and the application of forces causes by the cement flow. An exemplary system utilizes Rf energy in combination a conductive bone cement for selectively polymerizing the inflow plume to increase the viscosity of the cement. In one aspect of the invention, the system utilizes a controller to control bone cement flow parameters to either allow or disallow cement interdigitation into cancellous bone. A method of the invention includes pulsing the flows of bone cement wherein high acceleration of the flow pulses can apply expansion forces across the surface of the cement plume to reduce a vertebral fracture.

  • Patent number: 9603590
    Abstract: A single-arm stabilizer having suction capability includes a single, small leg through which suction can be applied. The leg has an upper surface and a lower surface that are spaced apart to define a chamber. The lower surface includes a plurality of openings that are disposed adjacent each other. A support arm is connected to the leg in order to position the leg as desired. A suction line is in fluid communication with the chamber in order to create a vacuum within the chamber. The stabilizer can be used to stabilize any desired portion of a patient's body, but is particularly effective at stabilizing the septum of a patient's heart. Such stabilization can be accomplished by inserting the leg into the patient's heart through the aorta.
