摘要： Medical devices with radiopaque three dimensional filtration matrices provide for improved visualization of the device within a vessel. In some embodiments, the three dimensional filtration matrix comprises fibers, such as surface capillary fibers. Visualization of the three dimensional filtration matrix provides for an evaluation of the proper deployment of the three dimensional filtration matrix. Radiopaque surface capillary fibers can be advantageously incorporated into other medical devices. Radiopaque surface capillary fibers can be formed by extrusion of a radiopaque polymer or polymer composite.

摘要： Clot engagement element comprising bundle of unwoven fibers can be assembled to form an acute stroke treatment device. The device has the capability of forming a three dimensional filtration matrix comprising effective pores with a distribution of sizes. The bundle of fiber design allows the device to be effectively delivered into circuitous cerebral arteries to remove clot that causes stroke. The fiber bundle based filtration matrix offers the advantages of conforming to the changing inner perimeter of a blood vessel during a clot removal process and thus the capability to effectively retain and remove a clot in the vessel. The filtration matrix offers the additional advantage to trap any break-off of the clot during the removal process. A plurality of fiber bundles can be combined to form an effective clot engagement element. Supplemental engagement structure as well as mechanical treatment structure can be integrated into the stroke treatment device. The deployment of the fiber based elements can be facilitated by actuation tool. Aspiration can be employed during the clot removal process.

摘要： Various devices are described to provide filtering of flow from the aorta to the left carotid artery and the right carotid artery. The filters can be brought into a desired position through one or more peripheral arteries. A single filter device can provide the desired filtering or a plurality of devices can be used. In particular a single filter device can span between the brachiocephalic artery and the left carotid artery. These filter devices can be used effectively to capture emboli generated during procedures on the heart so that emboli do not travel to the patient's brain where the emboli can cause a stroke or other adverse event. In particular, these filters can be used during percutaneous procedures on the heart, such as endovascular heart valve replacement.

摘要： Improved embolism protection devices comprises fibers that can have one configuration for delivery of the device and a second configuration in which the device is deployed for filtering of flow within a vessel. In some embodiments, the fibers can be connected to a fiber support, which is connected to an actuating element. The actuating element controls the transition from the delivery configuration to the deployed configuration. The embolism protection device can comprise a guidewire. The fibers can be attached at one end to a fiber support structure and at another end to the guidewire. A hypotube can be attached to the proximal end of the fibers while the guidewire is attached at the distal end of the fibers with the guidewire extending within a central channel of the hypotube. The hypotube can be used to guide the delivery of treatment structures, such as a balloon and/or a stent.

摘要： Thrombectomy catheters are presented that have curved tip portions. A suction lumen extends from at or near the proximal end of the catheter to a suction port at or near the tip portion of the catheter. The curves of the thrombectomy catheter can be selected to place a suction port at or near a vessel wall for the more effective removal of thrombus resulting from directing the suction in the direction of the thrombus. In some embodiments, the tip portion of the catheter can be transitioned from a first configuration for delivery of the catheter into the vessel to a second more curved configuration with a desired design for application of suction. The catheter can be moved in a circumferential and/or lateral direction to cover selected portions of the inner vessel wall. In some embodiments, a partially occlusive structure can be used to reduce and/or redirect flow within the vessel to improve performance of the thrombectomy.

摘要： Methods for the removal of an embolism protection device use aspiration during the drawing of the embolism protection device into the catheter. Generally, the embolism protection device comprises a three dimensional filtering matrix that provides improved filtering without blocking the flow through the patient's vessel. In some embodiments, the embolism protection device can be actuated between a deployed configuration and a removal configuration with a reduced area across the cross section of the vessel lumen. The embolism protection device in the removal configuration can be drawn within the aspiration catheter. The aspiration catheter can have a distal portion with an expanded compartment with an average diameter at least about 20 percent larger than the average diameter of the shaft of the catheter within about 10 centimeters of the expanded compartment. In a rapid exchange version, the rapid exchange segment can have a length of at least about 10 centimeters.
