Abstract
A distal protection device for use in a body lumen. The device includes a functional element which may be a filter or an occlusive element. The device includes means for controlling the movement and placement of the functional element along a guidewire. Motion of the guidewire can be independent of the motion of the functional element.
Claims33
A distal protection device for use in a body lumen comprising:
- a first elongate member having distal and proximal ends;
- a second elongate member having distal and proximal ends;
- a functional element carried by the second elongate member, the functional element being expandable from a delivery configuration to an expanded deployed configuration when the functional element is deployed in the body lumen;
- and
- the second elongate member being carried by the first elongate member;
- the first and second elongate members being moveable over a limited range of motion from a first relative axial position to a second relative axial position such that when the functional element is deployed in the body lumen the first elongate member may be moved without resulting in corresponding movement of the functional element, the distal end of the second elongate member being distal to the distal end of the first elongate member over the entire range of motion, and the first and second elongate members being sized and configured such that the proximal end of the second elongate member is located in the body lumen over the entire range of motion.

A method of filtering emboli from blood flowing through the lumen of a vessel or occluding blood flow through the lumen of the vessel comprising:
- providing a distal protection device, the distal protection device comprising:
- a first elongate member having distal and proximal ends;
- a second elongate member having distal and proximal ends;
- and
- a functional element carried by the second elongate member, the functional element being expandable from a delivery configuration to an expanded deployed configuration when the functional element is deployed in the body lumen;
- and
- the second elongate member being carried by the first elongate member;
- the first and second elongate members being moveable over a limited range of motion from a first relative axial position to a second relative axial position such that when the functional element is deployed in the body lumen the first elongate member may be moved without resulting in corresponding movement of the functional element, the distal end of the second elongate member being distal to the distal end of the first elongate member over the entire range of motion, and the first and second elongate members being sized and configured such that the proximal end of the second elongate member is located in the body lumen over the entire range of motion;
- introducing the distal protection device into the lumen of the vessel with the functional element in its delivery configuration;
- advancing the distal protection device through the vessel until the functional element is positioned at a desired location distal to the treatment site;
- and
- expanding the functional element to its expanded deployed configuration.
