摘要： An embolic protection filter for collecting particulate debris in a body lumen and method of making same. The embolic filter includes a spirally cut outer tubular member disposed about a spirally cut inner tubular member, the spiral cuts having opposite chirality. The embolic filter is transformable between a collapsed configuration and an expanded configuration wherein filter openings are defined by intersections of the spiral cuts. The spiral cuts may have a variable pitch for sizing the filter openings to be larger in a proximal portion of the filter for receiving embolic debris, and smaller in a distal portion of the filter for retaining embolic debris within the filter. In an embodiment of the invention, the length of the expanded configuration is substantially equal to the length of the collapsed configuration.

摘要： An occlusion device is formed of an electroactive polymer element mounted on an elongated shaft. The electroactive polymer element includes an outer electrode, an inner electrode, and an electroactive polymer film disposed between the inner and outer electrodes. The electroactive polymer element may be formed in a hollow, generally cylindrical shape such that a longitudinal opening is formed inside of the inner electrode. The elongated shaft may be a guidewire or catheter. The inner and outer electrodes are coupled to an electrical power source such that an electrical voltage can be applied between the inner and outer electrodes. Upon application of the electrical voltage between the inner and outer electrodes, the electroactive polymer element expands to block a blood vessel of a patient.

摘要： A system and method for inflating and deflating a catheter balloon using osmosis. An elongate catheter shaft has a proximally disposed osmotic membrane in fluid communication with a distally mounted balloon through a fluid-filled catheter lumen. The balloon is inflated by exposing the exterior of the membrane to a solution that is hypotonic relative to the solution within the catheter lumen. The balloon is deflated by exposing the exterior of the membrane to a solution that is hypertonic in relation to the solution within the catheter lumen.

摘要： A girdle for surrounding the chordae tendinae of a heart valve, and a system and method for delivering the girdle. The girdle gathers the chordae tendinae into a bundle to effectively shorten the chordae tendinae to resolve or reduce valve leaflet prolapse. The system includes a girdle releaseably carried within a delivery catheter, and a push rod to release the girdle from the delivery catheter. The girdle has a filamentous linear delivery configuration and one of several annular treatment configurations. The girdle may have a locking mechanism for locking the girdle in an annular treatment configuration.

摘要： A ring for surrounding the chordae tendinae of a heart valve, and a system for delivering the ring. The ring gathers the chordae tendinae into a bundle to effectively shorten the chordae tendinae to resolve or reduce valve leaflet prolapse. The body of the ring has an elongated generally linear delivery configuration and a plurality of annular treatment configurations. The body of the ring is releasably carried within a delivery catheter to a treatment location, and a push rod expels the ring from the delivery catheter. Upon being expelled from the delivery catheter, a second end of the ring body will co-axially align with and insert into a first end of the body to form the ring.
