  • Publication number: 20070198051
    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. 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. When the filter element is in the expanded configuration, the average pore size is from 30 to 300 microns and the standard deviation of the pore size is less than 20 percent of the average pore size. The filter element has two or more filtering layers, each filtering layer having pores, each filtering layer being adjacent to at least one other filtering layer, and at least one of the filtering layers being made of a self-expanding material.

  • Publication number: 20070168018
    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.

  • Publication number: 20070118207
    Abstract: The present invention provides a delivery mechanism for percutaneously routing a stent or graft through the vascular system and procedures for addressing an aneurysm or an otherwise damaged vessel. The delivery system includes an outer tubular guide catheter 20, an inner tubular delivery (pusher) catheter 14 coaxially disposed and slidable relative to the outer guide catheter and an elongated flexible wire or cable 26 that is coaxially insertable through the lumen of the inner tubular catheter and that has a frusto-conical bead affixed at the distal end thereof which is sized to at least partially fit within the lumen of the inner pusher catheter when a proximally directed tension force is applied between the elongated flexible wire or cable 26 with respect to the pusher catheter 14.

  • Patent number: 7192434
    Abstract: An embolic protection device or system for use in a lumen of a vessel in a patient's vascular system. The device filters debris and blood clots in a body lumen and/or prevents them from moving distally from a treatment site in a vessel and causing emboli. The device may include a filter placed distally of the treatment site. The device may include an occlusive element placed either distally or proximally of the treatment site.

  • Publication number: 20060241690
    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.

  • Publication number: 20060173300
    Abstract: A system and method for sizing and imaging of cardiovascular defects generally are disclosed capable of producing model images or forms that mimic the shape of defects such as openings or breaches in cardiac septum walls, so that remedial devices of the correct size and shape can be administered to occlude defects. The system uses a three-dimensional open wire imaging structure which is flexible, easy to position and does not occlude blood flow and when expanded, can be measured in situ.

  • Publication number: 20060167490
    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.

  • Publication number: 20060052817
    Abstract: A distal tip for use with a medical catheter. The tip includes a member having a wall which defines a lumen therewithin. The wall has a portion at a distal end thereof, the portion curving inwardly toward an axis of the lumen. The lumen is provided with a diameter adaptable to accommodate a device to be recovered therewithin.
