  • Publication number: 20210378645
    Abstract: A collapsible medical device and methods for deploying the same are provided. The medical device includes a tubular metal fabric, which includes a plurality of braided metal strands and a proximal end and a distal end, the tubular metal fabric having a collapsed configuration for delivery and an expanded preset configuration for creating an occlusion of an opening. In the expanded preset configuration, the device has two expanded disk portions and a central portion, a first expanded disk portion and the central portion connected by a first reduced diameter portion, and a second expanded disk portion and the central portion connected by a second reduced diameter portion. Each of the first and second reduced diameter portions is smaller in diameter than both the two expanded disk portions and the central portion, and each of the first and second reduced diameter portions is recessed into the central portion.

  • Publication number: 20210378646
    Abstract: 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.
