Abstract: A medical device is movable between first and second positions. The medical device has an actuator which is movable between a relaxed position and a stacked position. The stacked position of the actuator deforms the medical device toward the stacked position of the actuator. When the actuator is in the relaxed position, the shape of the medical device is primarily determined by the shape of a main element.
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.
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. The balloon or inflatable member be situated in a recess in the outer wall of the inventive catheter. Additionally, the distal end of the catheter past the balloon may be tapered. The catheter has a very low profile as compared to other catheters of the neurovascular balloon catheter genre. It may include other features such as variable stiffness along the axis of the device and anti-kinking components. The balloon may be compliant in nature.

Abstract: This is a medical device, specifically used in surgery. It is a wire having distal radio-opaque markers and may be used, for instance, in endovascular procedures as a marker wire for estimating or referencing the structural attributes of internal physical features. In addition, the inventive marker wire may be used as a guide wire for a catheter used in endovascular procedures.

Abstract: An intravascular filter having a filament which expands a filter element. The filament is a coil which is stretched to reduce the diameter of the coil for introduction. The filter element is preferably biased toward the closed position and is opened by the coil when tension is released on the coil. The filament slides along the internal surface of the filter element so that the filter element may assume intermediate positions.
Abstract: A device for delivering an occlusion element, or other medical device, which includes a fluid dissolvable bond. The occlusion element is coupled to the delivery element with the fluid dissolvable bond. The bond may be dissolved by delivering a fluid through the delivery element either through the delivery element itself or through a tube positioned in the delivery element.

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.

Abstract: A system for treating a vascular malformation has an expandable device and a heating device for heating and shrinking the malformation. The expandable device may have deformable elements which plastically deform in the expanded position. The balloon may be self-expanding, balloon expanded or expanded with an actuating rod. A fluid, such as saline, may be introduced during heating when using RF heating. A sealant may also be introduced into the expandable device to further seal the aneurysm.
