  • DEVICES AND METHODS FOR TREATING VASCULAR MALFORMATIONS
    Publication number: 20110224776
    Abstract: A device for treating vascular malformations includes a primary coil and secondary windings. The primary coil provides resilience and structural integrity while the secondary windings fill interstitial spaces in the primary coil to isolate the vascular malformation. The device may have increased density along a central portion to isolate the malformation. In another aspect, the device may have a central opening through which embolic materials may be delivered.

  • Balloon Catheter
    Publication number: 20110172699
    Abstract: This is a balloon catheter having at least two lumens. One of the lumens is a large working lumen. The balloon catheter is especially useful as a guide catheter or micro catheter and may be used in a variety of therapeutic and diagnostic procedures. In particular, it has value in treating neurovascular embolic strokes in combination with other devices which are delivered to the stroke site through that working lumen. The remainder of the lumens typically are used to inflate and to deflate the balloon.

  • SYSTEMS, METHODS AND DEVICES FOR REMOVING OBSTRUCTIONS FROM A BLOOD VESSEL
    Publication number: 20110166586
    Abstract: A system for removing an obstruction from a blood vessel includes an obstruction engaging element and an expandable capture element. The capture element preferably has a flexible cover and an expandable support structure. The engaging element engages the obstruction and moves the obstruction into the capture element. The capture element protects the obstruction when the obstruction is moved into the catheter.
