摘要： Filters and method of manufacturing filters are disclosed herein. The filter has a substantially sack-like shape having a closed distal end and an open proximal end. The filter can be constructed from thin film. The filter material can be an organic or inorganic polymer. In one embodiment, the filter material is a polyurethane film having a thickness of les than 25 μm. The filter can be constructed from one or more sections of filter material. In the two-section embodiment, the outer edges of the first and second sections are overlapped and bonded using solvent, heat or other bonding process. In the single-section embodiment, the outer edges of the first section are overlapped and bonded using bonding agents, such as solvent or adhesive, heat or other bonding process. Filters of the present invention have a reduced amount of hysteresis so as to reform to its original shape when deployed.

摘要： The present invention includes systems, methods, and apparatus configured to close an internal tissue opening, such as an internal tissue opening cased by an atrial septal defect including a patent foramen ovale defect, ventricular septal defect, patent ductus arterosus defect, or the like. For example, a closure device includes a right anchor cooperatively coupled with a left anchor, where the right anchor and left anchor are configured to be positioned about the internal tissue opening. The left and/or right anchor are configured to close the internal tissue opening in one instance, and to provide tissue stimulating or growth-encouraging substances at the tissue opening. Additional aspects of the invention relate to shape, formation, positioning, and detachment of the closure device about the internal tissue opening.
