Abstract: A speaker packaging device. The speaker packaging device comprises a base plate for supporting a plurality of speakers. The speaker packaging device also comprises a series of transverse baffles and a series of pairs of longitudinal baffles. The transverse baffles and the longitudinal baffles interlock over the base plate, forming a matrix of individual cells, or baffle units. Notches are preserved along each longitudinal baffle for accommodating the outer edges of the respective speakers within each baffle unit. In addition, a gap is preserved between adjacent baffle units to further accommodate the outer edges of the respective speakers. The notches are staggered along adjacent baffle units to conserve space.

Abstract: Implantable occlusion devices that include one or more flanges extending from a tubular body are disclosed. The flange or flanges may assist in retention of the device within a vessel, cavity, appendage, etc. At least one flange on the occlusion device may include a concave surface proximate one end of a body. Because of the shape of the flange, e.g., its concavity, the occlusion device may resist dislocation due to e.g., the forces generated within the left atrial appendage during atrial fibrillation.

Abstract: Described herein are a collapsible medical device and associated methods of occluding an abnormal opening in 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.
