  • Publication number: 20140025117
    Abstract: A spinal implant with associated surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

  • Patent number: 8585713
    Abstract: Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself. Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.

Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can comprise a three-step progressive treatment process that includes immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis and maceration. The progressive, or modular, treatment can be provided by a system or kit of one or more treatment devices.

  • Patent number: 8454649
    Abstract: A liquid embolic delivery system is provided for trapping an injected liquid embolic composition to prevent the liquid embolic from solidifying or otherwise passing outside of an embolization area. The delivery system includes a catheter for delivery of a liquid embolic composition and a containment member positioned at a distal end of the catheter which is shaped to trap the liquid embolic composition delivered through the lumen of the catheter. The containment member is formed as a brush, nest, sponge, swab, flexible sack, or other shape into and around which the liquid embolic composition is injected. The liquid embolic composition is trapped or meshes with the containment member during solidification containing the liquid embolic and preventing the embolic composition from passing into the blood stream.

  • Publication number: 20130018473
    Abstract: Methods for correcting a deformit in the spine by forming a trans-sacral axial instrumentation/fusion axial bore through vertebral bodies in general alignment with a visualized, anterior axial instrumentation/fusion line in a minimally invasive, low trauma, manner and providing a therapy to the spine employing the axial bore. Curved or relatively straight anterior axial bores are formed from the anterior starting positions. The therapies performed through the axial bores include discoscopy, full and partial discectomy, vertebroplasty, balloon-assisted vertebroplasty, drug delivery, electrical stimulation and various forms of spinal disc cavity augmentation, spinal disc replacement, fusion of spinal motion segments and implantation of radioactive seeds. Axial spinal implants and bone growth materials can be placed into single or multiple parallel or diverging TASIF axial bores to fuse two or more vertebrae, or distract or shock absorb two or more vertebrae.

  • Publication number: 20120116443
    Abstract: Devices for restoring blood flow to facilitate lysis of clots and/or enable capture of clots are disclosed. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The devices can include an elongate pusher member and a self-expandable capturing member coupled to a distal end of the elongate pusher member. The capturing member can comprise a generally cylindrical body having an cell structure that is configured to compress the clot against an inner wall of the neurovasculature and capture the clot at least partially on a surface of the generally cylindrical body upon deployment of the capturing member from the microcatheter, thereby restoring blood flow to the neurovasculature downstream of the clot.
