A collapsible medical device and associated methods of occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from plural layers of a heat-treatable metal fabric. Each of the fabric layers is formed from a plurality of metal strands and the assembly is heat-treated within a mold in order to substantially set a desired shape of the device. By incorporating plural layers in the thus-formed medical device, the ability of the device to rapidly occlude an abnormal opening in a body organ is significantly improved.

Multi-layer braided structures for occluding vascular defects

A distal protection device for use in a body lumen. The device includes a functional element which may be a filler 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.

Distal protection devices having controllable wire motion

A distal protection device for use in a body lumen includes a functional element, which may be a filter or an occlusive element. The device includes a first elongate member, a second elongate member carried by the first elongate member, and the functional element carried by the second elongate member. Motion of the first elongate member can be independent of the motion of the functional element.

A guide wire comprising an elongate, flexible core having a proximal region, a proximal end, a distal region, and a distal end; and a plurality of wire strands wrapped helically parallel to one another and disposed on at least a portion of the distal region of the core.

Guide wire with stranded tip

A device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body. The device has a filter element being expandable from a collapsed configuration to an expanded configuration. The filter element includes a material having pores, and the material having pores includes cylindrical wires having at least three different diameters arranged in a pattern of graduated diameters.

Embolic filters with controlled pore size

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.

Everted filter device

An embolic protection device or system for use in a lumen of a vessel in a patient's vascular system. The device filters debris and blood clots in a body lumen and/or prevents them from moving distally from a treatment site in a vessel and causing emboli. The device may include a filter placed distally of the treatment site. The device may include an occlusive element placed either distally or proximally of the treatment site.

Vascular protection devices and methods of use

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.

The present invention provides for a drug delivery mechanism for use with a protection device. The protection device has an expandable filter. The drug delivery mechanism automatically delivers a drug to the filter without requiring the intervention of the operator of the protection device. The drug delivered to the filter facilitates continued filter patency during the medical procedure.
