摘要： An intravascular flow restrictor comprises a braided tubular structure designed to be placed in the main pulmonary artery for limiting blood pressure in the lungs. The braided structure is designed to be collapsed for placement in a delivery catheter but when ejected from the delivery catheter, assumes a substantially larger diameter disk shaped device having one or more longitudinal channels or passways therethrough.

摘要： 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.

摘要： The present invention provides a method of forming a medical device and medical devices which can be formed in accordance with the method. In one embodiment, the method includes the steps of a) providing a metal fabric formed of a plurality of strands formed of a metal which can be heat treated to substantially set a desired shape; b) deforming the metal fabric to generally conform to a surface of a molding element; c) heat treating the metal fabric in contact with the surface of the molding element to substantially set the shape of the fabric in its deformed state; and d) removing the metal fabric from contact with the molding element. The resulting metal fabric will define a medical device which can be collapsed for passage through a catheter or the like for deployment in a channel of a patient's body. Medical devices made in accordance with this method can have varying structures.

摘要： Embolic protection devices and systems capture and/or deflect emboli from entering one or more arterial branches of the aorta. An embolic protection device may include an anchor section that is positionable within an arterial branch of the aorta and a shield section that is operatively coupled to the anchor section. The shield section is positionable relative to one or more ostia of the aortic branches and is held in that position by the anchor section.

摘要： 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 L2 does not block blood flow to the renal arteries while the portion L2 prevents the aneurysm to grown and burst.

摘要： A self-expandable ring seals a gap between a medical device and adjacent body tissue. The ring is disposed about the medical device and configured to self-expand from a first radius in a compressed condition to a second radius in an expanded condition, the second radius being greater than the first radius. The ring may be formed from a compliant biocompatible foam configured and arranged to conform to the body tissue.

摘要： Embodiments of the present disclosure are directed to medical devices, methods, and systems for delivering a medical device to a target site. In one embodiment, a medical device includes a tubular member having a proximal end and a distal end, the tubular member having an expanded configuration and a relaxed configuration. The medical device further includes a tether comprising a first end and a second end, the first end coupled to the proximal end or the distal end of the tubular member. In addition, the medical device includes an engagement member coupled to the second end of the tether and disposed at least partially within the tubular member and between the proximal and distal ends of the tubular member in the relaxed configuration. The engagement member is configured to engage the proximal or distal end of the tubular member, opposite the first end of the tether, upon displacement of the proximal and distal ends of the tubular member towards one another, such that the tubular member is locked in the expanded configuration.

摘要： Embodiments of the present disclosure are directed to medical devices for treating a target site. For example, a medical device comprises a tubular member having a proximal end and a distal end, the tubular member having an expanded preset configuration when deployed at the target site and a reduced configuration for delivery to the target site. The tubular member comprises at least one layer of braided fabric, and the at least one layer of braided fabric comprises a plurality of first strands having a first diameter and a plurality of second strands having a second diameter. The first diameter is larger than the second diameter. The plurality of first strands and the plurality of second strands are intertwined to define regions of varying radial stiffness between the proximal and distal ends of the tubular member.
