摘要： The present invention is a radiopaque distal embolic protection device for use in a lumen of a patient's body, such as a blood vessel. The protection device has an expandable and retractable filter attached to a distal portion of a guidewire. At least a portion of the filter has a radiopaque coating for viewing under fluoroscopy during use. The radiopaque coating allows the operator to ensure that the periphery of the filter has fully engaged the wall of a blood vessel and to take appropriate measures in recovery of the protection device after capture of emboli and particulate matter.

摘要： The invention provides a device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body comprising a filter element. The filter is expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained, and the filter element comprises a self-expanding material having pores. When the filter element is in the expanded configuration, the average pore size is from 30 to 300 microns and the standard deviation of the pore size is less than 20 percent of the average pore size.

摘要： A method and system of performing an intravascular procedure at a treatment site in a vessel of a patient. A device creates a seal to prevent the flow of blood during the treatment of vascular disease. A seal may be formed between the distal inside diameter of a sheath or catheter such as a guide catheter as well as within a vessel, such as an artery or vein. An elongated device having a distal portion extending from the catheter and having a fluid impermeable membrane disposed about at least the distal end of the device is used to seal the vessel. The system includes a device to occlude blood flow and a distal protection device to filter or remove embolic debris.

摘要： Everting filter devices and methods for using the devices, including using the devices as intra-vascular filters to filter thrombus, emboli, and plaque fragments from blood vessels. The filter devices include a filter body nominally tubular in shape and having a large proximal opening. The filter body can extend from a proximal first end region distally over the non-everted exterior surface of the filter, further extending distally to a distal-most region, then converging inwardly and extending proximally toward the filter second end region, forming a distal everted cavity. The degree of eversion of the filter can be controlled by varying the distance between the filter first end region near the proximal opening and the closed second end region. Bringing the filter first and second end regions closer together can bring filter material previously on the non-everted filter exterior to occupy the distal-most region. The everting process can also bring filter material previously in the distal-most position further into the distal everted cavity. The filter devices can be used to remove filtrate from body vessels, with the filtrate eventually occluding the distal-most region. The filter can then be further everted, bringing fresh, unoccluded filter material into place to provide additional filter capacity. Some everting filters have the capability of switching between occluding and filtering modes of operation, thereby allowing a treating physician to postpone the decision to use filtering or occluding devices until well after insertion of the device into the patient's body.
