    摘要: A filtering device for capturing and removing embolic debris from a body vessel and a system for insertion and removal of the filtering device to facilitate an interventional procedure in a stenosed or occluded region of a body vessel. The filtering device is adapted to be expandable in the body vessel, allowing blood to pass therethrough while maintaining apposition with the body vessel wall and capturing embolic material released into the bloodstream during the interventional procedure, and to be collapsible to remove the captured embolic material from the body vessel. The filtering device includes a guide wire, an expandable cage assembly secured to the guide wire, filter material secured to the expandable cage assembly, and at least one hinge, the hinge allowing the expandable cage assembly to bend independent from the guide wire. The system, which includes a delivery sheath and filtering device, is adapted to retain the expandable cage assembly in a collapsed condition and deliver and deploy the filtering device at a location in the body vessel distal the treatment site.

    摘要: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The lengths and positioning of the first and second control arms of each half frame can be varied to create an expandable frame which conforms to the size and shape of the body vessel in which the filtering device is deployed. Additionally, the radius of the partial loops, along with the length of the arc of the partial loops, can be varied on each of the frames to create a composite filtering assembly that can easily adapt to the size and shape of the body vessel. Additionally, the control arms of the half frames can be disposed either proximally or distally of the composite loop to create a distinct filtering structure.

    摘要: A self-expanding cage for use in conjunction with an embolic filtering device includes one or more circumferential members adapted to expand from an unexpanded position to a expanded position within the patient's body vessel. At least one proximal strut and at least one distal strut are attached to the circumferential member to form the basket. The circumferential member may include a plurality of bending regions which enhance the ability of the circumferential member to move between the unexpanded and expanded positions. The proximal and distal struts can be attached to one of the bending regions. When two or more circumferential members are utilized, each member may be connected by a connecting strut which may be connected at a bending region. The connecting strut can be a straight segment or may have a non-linear shape to provide additional flexibility. The expandable cage can be mounted to a elongated member, such as a guide wire, and can be either permanently mounted or rotatably mounted thereto.

    摘要: A separate deliverable embolic protection device filter that attaches to a helical coil at a distal end of a conventional guide, for use in a blood vessel when an interventional procedure is being performed to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filter assembly with a proximal end and a distal end, and a guide wire connector attached to the distal end of the filter assembly. The guide wire connector is able to couple with the helical coil of the guide wire. A restraining sheath placed over the filter assembly in a coaxial arrangement maintains the filter assembly in a collapsed position and delivers the filter assembly separately to the helical coil of the guide wire, and then the guide wire connector is joined to the helical coil. Alternatively, the guide wire can include a rotatable coil section forming a portion of the distal tip coil on the guide wire which is adapted to be coupled to the filter assembly. This arrangement allows the filter assembly to be rotatably mounted onto the guide wire.

    摘要: A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient's vasculature.
