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.

Embolectomy devices and methods for treatment of acute ischemic stroke condition

Systems for less invasive medical procedures comprise a filter device mounted on an integrated guiding structure and an aspiration catheter. These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient's vasculature. The catheter can have a radiopaque band that is held in place under metal wire embedded within the polymer forming the tube of the catheter. In some embodiments, the aspiration catheter has a small diameter distal portion that can access into small diameter vessels in which the distal portion has a smaller average diameter than the remaining tube of the catheter.

Aspiration catheters for thrombus removal

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.

Embolic protection during percutaneous heart valve replacement and similar procedures

A deflection and support catheter provided for improved manipulation of elongated medical devices used during percutaneous procedures in difficult to reach situations. In particular, the deflection and support catheters can facilitate placement of guidewires, guide catheters, and intervention devices such as angioplasty balloons and stent delivery devices.

Deflection control catheters, support catheters and methods of use

Systems for less invasive medical procedures comprise a filter device mounted on an integrated guiding structure and an aspiration catheter. These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient's vasculature. The filter device can involve improved torque coupling with a torque coupler associated with a resilient member that correspondingly also provides increased flexibility relative to an overtube that forms a tube for the remaining portions of the device. An actuation tool for the filter device used a systematic loading procedure for proper loading of the corewire and overtube into the actuation tool. A fiber cartridge comprises fibers loaded as a bundle into the cartridge for delivery with the ends of the fibers respectively bonded to radiopaque markers that can be visualized to come together when the filter is properly deployed. The aspiration catheter generally has a rapid exchange format. The catheter can have a radiopaque band that is held in place under metal wire embedded within the polymer forming the tube of the catheter. In some embodiments, the aspiration catheter has a small diameter distal portion that can access into small diameter vessels in which the distal portion has a smaller average diameter than the remaining tube of the catheter.

The various embodiments disclosed herein relate to introducer sheaths having an expandable and retractable shaft configured to receive a positionable medical device therethrough. In some embodiments, the shaft is selectively expandable and retractable based on the position of the positionable device within the shaft.
