    摘要: A vascular occlusion device deployment system for placing an occlusion device at a preselected site within the vasculature of a patient. The deployment system employing a pusher having a lumen with an opening at the distal end of the pusher. A vascular occlusion device is connected to the distal end of the pusher by a portion that is removeably disposed within the opening. The portion of the occlusion device is forced out of the opening by an expandable reaction chamber, thereby deploying the occlusion device. The expandable reaction chamber, prior to deployment, has multiple chambers separated by a heat-dissolvable membrane. When the membrane is dissolved, components from the chambers react and expand, leading to deployment.

    摘要: A medical device for placing an embolic device at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member having a lumen therethrough and being slidably disposed within the lumen of the catheter. A stretch resistant embolic device is retained within the delivery catheter by a mechanical interlocking mechanism which includes an engagement member which is slidably disposed within the pusher member and extends through a retaining ring at the proximal end of the embolic device. A detachment member extends through an aperture at the distal end of the engagement member thereby locking the embolic device onto the engagement member. The engagement member engages a retaining ring on the embolic device. When the embolic device is advanced to the predetermined site within the vessel, the detachment member is withdrawn from the aperture to thereby release the embolic device at the treatment site.

    摘要: A method as provided for occluding the vasculature of a patient. The method comprises the steps of providing a plurality of embolic coils having a textured surface. The embolic coils are introduced into the patient's vasculature. In this manner, the textured surface provides improved platelet adhesion compared to a non-textured surface, to promote clotting. In the illustrative embodiment, the embolic coil comprises a platinum-tungsten alloy wire and the texturing is performed by abrasion or sandblasting to provide substantially uniform roughness comprising pockets having diameters of about 0.125 microns to about fifty microns and depths of about 0.25 microns to about twenty microns.

    摘要: A self-expanding stent and stent delivery system are provided for treating vascular diseases such as partially occluded blood vessels within the brain. The self-expanding stent is preferably mounted on an elongated core wire including proximal, intermediate and distal cylindrical members disposed about the core wire. The proximal, intermediate, and distal cylindrical members are spaced apart such that first and second gaps are formed. The stent, which includes anchor members, is mounted on the intermediate cylindrical member such that the anchor members interlock within the gaps between the cylindrical members. The self-expanding stent and elongated core wire are disposed within a delivery lumen of a balloon catheter such that the balloon catheter compresses and constrains the stent about the intermediate cylindrical member to thereby interlock the stent onto the core wire. The elongated core wire further includes an expandable capture basket attached to the distal end of the elongated core wire in order to capture embolic debris released during the angioplasty of the blood vessel and the deployment of the self-expanding stent.

    摘要: A method and device used for treating an aneurysm or a vessel of a patient. An embolization element that is adapted to reduce or block the blood flow into the aneurysm or vessel, together with a stent connected to the embolization element, is provided. The embolization element includes an expandible member. The embolization element and the stent are introduced into the vessel leading to and communicating with the aneurysm or vessel. The embolization element is directed into the aneurysm or vessel, with the stent being located in another vessel communicating with the first vessel. In this manner, the stent becomes compressed against the inner wall of the second vessel for anchoring the embolization element. In one form of the invention, the stent comprises a helical coil and the embolization element comprises a collapsible framework.
