Methods and Devices for Removal of Thromboembolic Material

摘要

Methods and devices to remove thromboembolic material from the human body using rotational energy and aspiration are disclosed. A thromboembolic removal system includes an extraction device and drive unit. The extraction device is introduced to the treatment area and activated by the drive unit to separate, break apart, loosen or soften thromboembolic material and to facilitate its aspiration outside the patient.

主权项

1. An extraction device for removing thromboembolic material from a patient, comprising:
a drive unit that rotates within 100 to 500,000 RPM; an elongated rotational member made at least partially of cable having a proximal end that is connected to the drive unit, and a distal tip having a shaped configuration; and an aspiration catheter at least partially surrounding the rotational member and having an aspiration passage; wherein the rotational member traverses concomitant bends as the aspiration catheter during a therapeutic procedure.
