  • Publication number: 20140135803
    Abstract: Embolectomy catheters, rapid exchange microcatheters, systems and methods for removing clots or other obstructive matter (e.g., thrombus, thromboemboli, embolic fragments of atherosclerotic plaque, foreign objects, etc.) from blood vessels. This invention is particularly useable for percutaneous removal of thromboemboli or other obstructive matter from small blood vessels of the brain, during an evolving stroke or period of cerebral ischemia. In some embodiments, the embolectomy catheters of this invention are advanceable with or over a guidewire which has been pre-inserted through or around the clot. Also, in some embodiments, the embolectomy catheters include clot removal devices which are deployable from the catheter after the catheter has been advanced at least partially through the clot. The clot removal device may include a deployable wire nest that is designed to prevent a blood clot from passing therethrough.

  • Publication number: 20140052233
    Abstract: Methods for treating a cerebral aneurysm are described. The method includes providing an expandable wire body support structure having a low profile radially constrained state, an expanded relaxed state with a substantially spherical or globular configuration having a smooth outer surface, and a porous permeable layer comprising a braided wire occlusive mesh disposed over at least a portion of the expandable wire body support structure at a first end, which is configured to cover an aneurysm opening. The support structure is advanced in the low profile radially constrained state within a microcatheter to a region of interest within a cerebral artery. The support structure is then deployed within the cerebral aneurysm, and the support structure expands to the expanded relaxed state within the cerebral aneurysm.

  • Publication number: 20130274866
    Abstract: An expandable support structure and methods of use for treatment of a patient's cerebral aneurysm are described. The support structure includes a fixed diameter ring and a plurality of elongate support members that are everted. The ring is secured to the plurality of elongate support members at a first end of the support structure. The support structure has a low profile, radially constrained state with an elongated tubular configuration having a low profile suitable for delivery from a microcatheter. The support structure also has an expanded relaxed state that defines a substantially globular hollow shape.

  • Publication number: 20130274862
    Abstract: An expandable support structure and methods of use for treatment of a patient's cerebral aneurysm are described. The support structure includes a plurality of elongate support members each having first and second ends that are both gathered at the first end of the support structure. Each elongate support member starts at the first end of the support structure, extends to an apex at the second end of the support structure, and extends back to the first end of the support structure. The support structure has a low profile, radially constrained state having a low profile suitable for delivery from a microcatheter. The support structure also has an expanded relaxed state that defines a substantially globular shape. In the expanded relaxed state, the apices of the elongate support members are arranged to define an open distal end.

  • Patent number: 8323306
    Abstract: A vaso-occlusive device includes a microcoil formed into a minimum energy state secondary configuration comprising a plurality of curved segments, each defining a discrete axis, whereby the device, in its minimum energy state configuration, defines multiple axes. Confinement of the device within an aneurysm causes it to assume a three-dimensional configuration with a higher energy state than the minimum energy state. Because the minimum energy state configuration of the device is larger (in at least one dimension) than the aneurysm, the deployed device is constrained by its contact with the walls of the aneurysm from returning to its minimum energy state configuration. The engagement of the device with the aneurysm wall minimizes shifting or tumbling due to blood flow.

  • Publication number: 20110005062
    Abstract: A vascular implant formed of a compressible foam material has a compressed configuration from which it is expansible into a configuration substantially conforming to the shape and size of a vascular site to be embolized. Preferably, the implant is formed of a hydrophilic, macroporous foam material, having an initial configuration of a scaled-down model of the vascular site, from which it is compressible into the compressed configuration. The implant is made by scanning the vascular site to create a digitized scan data set; using the scan data set to create a three-dimensional digitized virtual model of the vascular site; using the virtual model to create a scaled-down physical mold of the vascular site; and using the mold to create a vascular implant in the form of a scaled-down model of the vascular site. To embolize a vascular site, the implant is compressed and passed through a microcatheter, the distal end of which has been passed into a vascular site.
