  • Publication number: 20210307735
    Abstract: A method for making a braided medical device may involve positioning an insert inside a braided material, processing the braided material to form the braided medical device, dissolving and/or crushing the insert into multiple pieces, and removing the multiple pieces from the braided medical device. In some embodiments, the insert is made of gypsum. A braided medical device for occluding a defect in a heart may include a right disc for residing in a right side of the heart, a left disc having a partially circular shape for residing in a left side of the heart, and a waist extending between the right disc and the left disc and having a smaller diameter than that of either the right disc or the left disc.

  • Publication number: 20210290248
    Abstract: This application describes various embodiments of an expandable device that includes at least one support member. The support member (or members) is integrated into the structure of the expandable device and increases its column strength, which thus augments pushability of the expanding device through a delivery catheter. The support member allows force applied while pushing from the proximal end of the expandable device to be translated to the distal end of the device and therefore avoid bunching or deformation without increasing the profile of the device to a degree that would prohibit passage through a lumen of a specific required size. Thus, the expandable devices described herein address at least some of the shortcomings discussed above.

  • Publication number: 20210283369
    Abstract: A method for making a neutral hybrid braided structure may involve positioning a first set of wires on a braiding machine in a first set of positions, positioning a second set of wires on the braiding machine in a second set of positions so that the first set of positions and the second set of positions form a neutral hybrid braiding pattern, and braiding the first set of wires and the second set of wires on the braiding machine to form the neutral hybrid braided structure. Each wire in the first set of wires has a first cross-sectional diameter, and each wire in the second set of wires has a second cross-sectional diameter that is smaller than the first cross-sectional diameter.

  • Patent number: 9445798
    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.

  • Patent number: 9402634
    Abstract: 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.

  • Publication number: 20150289965
    Abstract: 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 and a self-expanding radial element associated with the 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. The filter element comprises a self-expanding material having pores. The filter element has proximal and distal portions and a central portion, and has a shape in the expanded configuration which defines a cavity having a proximal facing opening. The self-expanding radial element is distal of the filter element, and the self-expanding radial element is adapted to maintain the filter element centered in the lumen.

  • Patent number: 8900287
    Abstract: A stent/graft especially designed to be used in a minimally invasive surgical procedure for treating an abdominal aortic aneurysm (AAA) comprises an innermost tubular structure of a length (L1) formed by braiding a relatively few strands of shape memory alloy wire. The pick and pitch of the braid are such as to provide relative large fenestrations in the tubular wall. A portion of the innermost tubular structure of a length L2<L1 is surrounded by a further braided tubular structure having relatively many strands that occlude the fenestrations of the innermost tubular structure. The composite structure can be stretched to reduce the outer diameter of the stent/graft, allowing it to be drawn into a lumen of a delivery catheter. The catheter can then be advanced through the vascular system to the site of the AAA and then ejected, allowing it to self-expand with the portion L2 bridging the aneurysm.
