    摘要： A device for occluding a septal defect is provided. In general, the occluding device has a contracted state that allows the occluding device to be received within a delivery device for deployment to the site of the defect and an expanded state that is achieved when the occluding device is deployed from the delivery device. The occluding device has a proximal portion, which may be substantially circular, a distal portion, which may be substantially ovaloid, and a connecting portion extending between the two. The distal portion may define first and second outer parts at opposite ends of the major axis, which may be bent or curved. The configuration of the proximal and distal portions allow the occluding device to securely engage the septal wall and be kept in position at the septal defect without causing substantial interference with the functioning of adjacent heart structures.

    摘要： A vascular device is provided that includes a tubular structure and an occluding structure. The tubular structure has inner and outer layers, with the occluding structure located between the inner and outer layers. Each of the inner and outer layers may define a different pick count, and the tubular structure may include a leading edge at a transition between the pick counts. The leading edge may be disposed at the distal end of the vascular device when the device is deployed from a delivery device. Furthermore, the occluding structure may have first and second layers formed by the inversion or eversion of the occluding structure and the subsequent coupling of its free ends to form a continuous structure. Thus, any loose ends may be sealed to minimize unraveling and/or shifting of the occluding structure within the tubular structure. A method of making the vascular device is also provided.

    摘要： 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.

    摘要： The invention provides a device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body comprising a filter element. The filter element is expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained. When the filter element is in the expanded configuration, the average pore size is from 30 to 300 microns and the standard deviation of the pore size is less than 20 percent of the average pore size. The filter element has two or more filtering layers, each filtering layer having pores, each filtering layer being adjacent to at least one other filtering layer, and at least one of the filtering layers being made of a self-expanding material.
