  • Publication number: 20040116960
    Abstract: Apparatus and methods are provided for use in filtering emboli from a vessel, wherein a vascular filter is disposed on a guide wire, the vascular filter having a support hoop disposed from a suspension strut so as to permit lateral eccentric displacement of the support hoop relative to a longitudinal axis of the guide wire. A blood permeable sac is affixed to the support hoop to form a mouth of the blood permeable sac. The support hoop is disposed obliquely relative to the guide wire and is capable of being properly used in a wide range of vessel diameters. The support hoop collapses the mouth of the blood permeable sac during removal of the vascular filter to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular filter of the present invention are also provided.

  • Publication number: 20040106944
    Abstract: An emboli capturing system captures emboli in a body lumen. A first elongate member has a proximal end and a distal end. An expandable emboli capturing device is mounted proximate the distal end of the first elongate member, and is movable between a radially expanded position and a radially contracted position. When in the expanded position, the emboli capturing device forms a basket with a proximally opening mouth. A second elongate member has a proximal and a distal end with a lumen extending therebetween. The lumen is sized to slidably receive a portion of the first elongate member. An expandable delivery device is mounted to the distal end of the second elongate member and is movable from a radially retracted position to a radially expanded position. The delivery device has a receiving end configured to receive the emboli capturing device, and retains at least the mouth of the emboli capturing device in a radially retracted position.

  • Patent number: 6053932
    Abstract: An emboli capturing system captures emboli in blood flowing in the vasculature. The emboli capturing system includes a guidewire having a longitudinal axis and defining a lumen along at least a portion thereof. An expandable member is coupled to a distal portion of the guidewire and has an interior being in fluid communication with the lumen in the guidewire. The expandable member is configured to receive fluid through the lumen to expand radially outwardly relative to the guidewire and have fluid removed from the interior thereof to collapse radially inwardly relative to the guidewire. The expandable member, when expanded, has a spaced portion thereof spaced radially outwardly from the guidewire. An emboli capturing device is coupled to the expandable member and is configured to deploy radially outwardly relative to the guidewire upon expansion of the expandable member.

  • Patent number: 5419774
    Abstract: This invention is a method and device for quickly removing thrombus from the vascular system, particularly from a saphenous vein graft which can have highly organized thrombus over its entire length. Thrombus is pulled into a chamber at the distal end of the thrombus extraction device as a result of negative pressure, a severing mechanism severs the portion of the thrombus that is in the chamber, and fluid under pressure is supplied to transport and dilute the blood and thrombus, which renders the thrombus more manageable and reduces the blood loss to the patient.
