摘要： An atherectomy catheter for removal of plaque buildup from the walls of a blood vessel. The atherectomy catheter includes a cutter assembly disposed at the distal end of a flexible guide tube that may be inserted into a vessel and directed to the occlusion. A proximal actuator assembly is adapted to impart both rotary and axial movement to the cutter. The cutter assembly includes a cutter having a forwardly extending annular cutting surface. A guide wire with a flexible spring tip extends forward of the cutter for guiding the cutter as it travels axially through the artery. All of the removed atheroma materials are collected within the device and a retention member carried by the guide wire and positioned in front of the cutter forms a cap to retain the collected atheroma materials. In a disclosed embodiment, the retention member is expandable, and in one of the preferred embodiments, the retention member may be expanded to engage the vessel walls to anchor the device during the cutting stroke.

摘要： An cutter apparatus for removing obstructive tissue has a distal housing having a window for invaginating tissue. An axially reciprocating and rotating cutting blade makes successive longitudinal cuts while slowly rotating across the open window. An axial guide assembly holds the cutting edge of the blade in a cutting path immediately adjacent to the inner surface of the housing. The shape and motion of the cutting blade pares off a generally uniformly thick slice of tissue from the stenosis and directs it toward the interior of the housing. A spiral parting edge opposed to the rotating cutting edge provides clean separation of the tissue slice from the stenosis. The tissue slice is received in a chamber internal to the housing and is retained by the blade and guide assembly for later removal from the patient.

摘要： An atherectomy device for removing stenosis materials from a vascular vessel is provided. The atherectomy device includes a flexible tubular member, a flexible drive means disposed within the tubular member, and a cutting assembly carried by the distal extremity of the tubular member. The cutting assembly includes a collection chamber which receives a cutting bit carried by the drive means. The cutting bit is rotated to remove materials from the stenosis and cause the removed materials to be withdrawn into the collection chamber as the bit is advanced. A second embodiment of the atherectomy device includes an anchor member coaxially mounted within a tubular cutting blade at the distal end of the catheter. The anchor member is first advanced into a region of stenosis where it becomes embedded, and the tubular blade is subsequently advanced over the anchor member to sever the stenosis. The tubular blade and anchor member may be retracted within the catheter and thus used to withdraw the several material from the blood vessel.

摘要： A vascular catheter includes a blade tip at its distal end. In the specific embodiments, a blade is mounted within the blade tip and a mechanism provided for extending the blade transversely when the blade tip is located within a region of stenosis. By extending the blade and axially translating the catheter so that the blade forms an incision within the region of stenosis, improved angioplastic treatment can be achieved.

摘要： Described herein are atherectomy catheters, systems and methods that include a distal tip region that may be moved laterally so that its long axis is parallel with the long axis of the main catheter body axis. Displacing the distal tip region laterally out of the main catheter body axis exposes an annular blade and opens a passageway for cut tissue to enter a storage region within the catheter. The annular blade may be internally coupled to a drive shaft that rotates the blade, and thus the exposed blade edge may have the same crossing profile (OD) as the rest of the distal end region of the catheter. Also described herein are gear-driven atherectomy devices that may use a cable drive shaft to actuate the annular blade. Both push-to-cut and pull-to-cut variations are described, as are methods for cutting tissue and systems including these atherectomy catheters.

摘要： A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.
