  • Patent number: 9855087
    Abstract: Surgical instruments and methods for delivering bone anchor assemblies into bone are disclosed herein. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. In general, a surgical instrument can include a handle assembly having an elongate shaft extending distally therefrom. The handle assembly can be configured to axially translate a stylet extending therethrough relative to a bone anchor assembly coupled to the elongate shaft, and it can be configured to move the stylet proximally in response to distal advancement of a bone anchor assembly into bone. The surgical instruments can include various mechanisms for adjusting the position of the stylet.

  • Publication number: 20160089187
    Abstract: In some embodiments, a connector can be configured to couple a first fixation element (e.g., a first rod) to a second fixation element (e.g., a second rod). One or both of the first and second fixation elements can be included with the connector, or one or both can be separately provided. In some instances, at least one of the fixation elements is previously implanted in a patient. The connector can provide one or more degrees of freedom between the first and second fixation elements. The connector can also include a locking element configured to (1) lock one or more of the fixation elements to the connector, and (2) lock one or more of the degrees of freedom between the fixation elements. The connector can be configured to snap onto or otherwise engage a fixation element in a manner that provides tactile and/or audible feedback to the surgeon.

  • Publication number: 20160058501
    Abstract: An CUSA having a cannula with an ultrasonic frequency vibrating tip with a flue disposed around the cannula. A first electrode is disposed on an outside of the flue and an RF generator provides current to the first electrode. A current flow is formed between the electrode and the tip and the tip acts as a ground. The first electrode can take the shape of a complete circumferential ring or a partially circumferential ring. The first electrode can be removably disposed on and/or movable along a length of the flue to allow the surgeon to “clip-on” or adjust the electrode at the position of their choice. A second electrode can be disposed on the outside of the flue and proximal to the first. A second current flow can be formed between the first electrode and the second electrode.

  • Publication number: 20160038721
    Abstract: A mechanism can include a step feature guidewire having a guidewire with a proximal end, a distal end, and a diameter. A self-expanding element can be disposed approximate to the distal end of the guidewire and can have at least two states which include a contracted diameter and an expanded diameter. The self-expanding element can be expandable under its inherent proprieties, based at least on its original shape and the nature of the materials that make up the element. Further, the expanded diameter can be approximately 70% to 280% of the guidewire diameter. While the guidewire is designed for passing through a body lumen while treating a patient, the expanded diameter is less than any body lumen diameter the guidewire is determined to pass through.

  • Publication number: 20160038150
    Abstract: An embolic device deployment system includes a catheter having a first lumen and proximal and distal ends. A notch is disposed in the first lumen, forming a second lumen. An embolic device has a retaining ring at the proximal end. An engagement member includes a distal loop extending through the retaining ring, and a proximal loop extending into the first lumen. An elongated detachment member can be disposed through the loops and have a detachment member bump disposed between the loops. When the detachment member is disposed within the distal loop and the distal loop is disposed within the retaining ring, the embolic device is engaged. When the detachment member is pulled proximally, the detachment member is withdrawn from the distal loop, and the detachment member bump contacts the proximal loop. These acts assist in the disengagement of the distal loop from the retaining ring to release the embolic device.

  • Publication number: 20150374418
    Abstract: The improvement is a spinal instrument (preferably, a bone screw driver) having a flexible shaft comprising a plurality of interlocking segments carried on a malleable core rod. The flexible shaft allows a screwdriver handle to be perfectly in-line with the cage inserter if desired, while still taking advantage of the tactile feel and torque transmission of the flex segment in its bent position. Accordingly, a surgeon can limit the amount of retraction and keep the driver handle close to the inserter without having to overcome the forces of the flexible segments' natural straight configuration.

  • Patent number: 9204812
    Abstract: Devices and methods useful for sensing or measuring a pressure and remotely indicating or communicating that pressure are provided. The devices and methods have particular utility in sensing pressures in implantable medical devices and more particularly in hydrocephalus shunts. In one exemplary embodiment, an implantable valve can include a housing having a reservoir adapted to receive fluid flow therethrough between an inlet port and an outlet port. The implantable valve can also include a needle-penetrable septum to allow fluid delivery to the reservoir and/or a needle guard disposed within the housing and adapted to protect the radio frequency tag from a needle penetrating into the housing. A radio frequency (RF) tag can be disposed within the reservoir and can be adapted to change one or more of its electromagnetic characteristics in response pressure applied thereto by fluid in or flowing through the reservoir.

  • Patent number: 9179922
    Abstract: A system is provided that includes an elongated introducer navigable through body vessels of a human subject and a pusher component for incorporation within the introducer. The pusher component includes a tubular portion with a slotted section. A radiopaque marker is secured to at least a portion of the slotted section such that an outer surface of the radiopaque marker is substantially flush with an outer surface of the tubular portion immediately proximal and/or immediately distal the radiopaque marker. According to a method of manufacturing such a component, the slotted section is formed by a laser cutting operation and a pre-assembly radiopaque marker member is crimped onto the slotted section.

  • Publication number: 20150305878
    Abstract: A method of determining disc space geometry with the use of an expandable trial having endplate-mapping capabilities. An expandable trial is inserted into the disc space and its height is adjusted to obtain the desired decompression and spinal alignment (which is typically confirmed with the use of CT or Fluoroscopic imaging). The endplate dome/geometry dome is then determined by one of the following three methods: a) direct imaging through the trial, b) balloon moldings filled with flowable in-situ fluid (for example, silicon, polyurethane, or PMMA) from superior/inferior endplates or c) light-based imaging through superior & inferior balloons.

  • Publication number: 20150273192
    Abstract: A system and method for draining at least one type of bodily fluid from a patient, including a chamber capable of being adjusted to hold one of at least a first volume of fluid and a second, smaller volume of fluid. The chamber has an inlet end with a barrier defining an opening and has an outlet end defining an outlet passage. The system further includes a valve with a valve seat and a valve closure member to define a usable volume within the chamber, and a movable adjustment member with a shaft passable through the opening in the barrier and terminating within the chamber at a first end. The first end of the shaft is connected to the valve seat, and the shaft has a plurality of features along its length engagable with corresponding engagement features in a fixed relationship with the barrier to enable the shaft to be advanced into the chamber to reduce the usable volume to be less than the first volume.
