The present invention provides an improved vascular occlusion device having improved flexibility and retention of the type fabricated from braided tubular metal fabric having an expanded preset configuration and an elongated collapsed reduced diameter configuration for delivery through a catheter to a treatment site and shaped to create an occlusion of an abnormal opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained. The device further including at least one disk portion adjacent a body cylindrical portion formed from the fabric and having a transition diameter between the disk and cylindrical portion, significantly smaller than the diameter of the disk and the diameter of the cylindrical portion.

Percutaneous catheter directed intravascular occlusion devices

Embodiments of the present invention provide an improved vascular occlusion device for occlusion of a passageway, cavity, or the like. According to one embodiment, a medical device for occluding a left atrial appendage is provided. The medical device includes a first portion having at least one plane of occlusion that is configured to be positioned outside of the left atrial appendage, and a second portion having at least one plane of occlusion that is configured to be at least partially positioned within a cavity defined by the left atrial appendage.

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.

Braided medical device and method

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.

Expanding medical device with support

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.

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.
