  • Publication number: 20110160761
    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 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.

  • Publication number: 20110130819
    Abstract: Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.

  • Patent number: 7875043
    Abstract: A solution is provided to release a tissue cinching loop within a body having a first thread having a first end and a second end, and a second thread having a first half having a first tip, a second half having a second tip, a bottom half having a link, and a top half, wherein the first end is inserted through the link. A first knot is formed around the first thread with the top half thereby forming a loop where the diameter of the loop decreases as the knot is pushed into the body and the first thread is pulled out of the body and where the loop is released within the body when the first end is pulled out of the body.

  • Publication number: 20100305617
    Abstract: Methods and apparatus for forming one or more trans-sacral axial instrumentation/fusion (TASIF) axial bore through vertebral bodies in general alignment with a visualized, anterior or posterior axial instrumentation/fusion line (AAIFL or PAIFL) in a minimally invasive, low trauma, manner and providing a therapy to the spine employing the axial bore. Anterior or posterior starting positions aligned with the AAIFL or PAIFL are accessed through respective anterior and posterior tracts. Curved or relatively straight anterior and curved posterior TASIF axial bores are formed from the anterior and posterior starting positions. The therapies performed through the TASIF 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.

  • Publication number: 20100286722
    Abstract: A temporary vascular filter system comprising a catheter and an elongate filter slideably carried near the distal end of said catheter. The vascular filter system can be inserted into a vessel percutaneously with the filter in a narrow-diameter “closed position” and expanded into a large diameter “open position” at the desired intravascular site. After deployment, the proximal portion of the catheter can be secured to the patient at the insertion site. While deployed, the filter component is capable of sliding along a portion of the catheter throughout a range of motion. The filter may have two filter meshes, which may have different degrees of porosity. The temporary vascular filter system can be left in the patient for hours or days and then collapsed into a withdrawal tube for removal from the patient.
