  • Publication number: 20090272388
    Abstract: Tools, devices and methods for treating a patient. An incision or puncture is made though the patient's skin and a delivery tract is made through an opening formed by the incision or puncture, subcutaneous fat and fascia, far into the patient's abdominal cavity. A guide member is inserted through the delivery tract and a distal end portion of the guide member is positioned at a target location within the abdominal cavity. An implantable device is delivered with the aid of the guide member, and the implantable device is attached to at least one internal body structure. A fillable member of the implantable device is at least partially filled with fluid. The guide member is removed and an adjustment member is attached to a conduit in fluid communication with the fillable member. The attachment member is anchored to an internal body structure and the incision or puncture is closed.

  • Publication number: 20090001633
    Abstract: A blow molding apparatus for expanding a polymer tube and a method for fabricating a stent using the apparatus is disclosed. The polymer tube is disposed within a tubular mold, over which a heated ring is made of a material having thermal conductivity greater than the tubular mold is translated. The ring is heated with heated fluid streams applied directly onto an outer surface of the ring, or heated fluid circulated within the ring, or an electrically resistive coil within the ring, or combinations thereof. The heated ring uniformly heats a circumference of the tubular mold that, in turn, uniformly heats a circumferential band of the polymer tube. The heated polymer tube is progressively expanded radially and axially while the ring is translated longitudinally over the polymer tube. The expanded polymer tube can be heat set and cooled prior to removal from the tubular mold.

  • Publication number: 20080275537
    Abstract: Polymeric stents having fracture toughness and resistance to recoil after deployment are disclosed along with methods of manufacturing such stents. Improvements to mechanical characteristics and other improvements may be achieved by having polymer chains within individual stent struts oriented in a direction that is closer to or in line with the axis of the individual stent struts. The desired orientation of polymer molecules may be achieved by one or any combination of extruding polymers into hollow tubes to induce axially oriented polymer chains, applying a tensile load to polymer tubes to induce axially oriented polymer chains, and radially expanding polymer tubes to induce circumferentially oriented polymer chains. Stent patterns include struts defining diamond shaped cells and/or W-shaped cells.

  • Patent number: 7416558
    Abstract: An intravascular stent includes an eluting sheath fabricated from a mesh for controlled release of therapeutic drugs and for delivery of the therapeutic drugs in localized drug therapy in a blood vessel. The eluting sheath is attached to at least a portion of an outside surface area of the stent structure and is fabricated from a mesh designed to neck down in response to a radially outward directed force resulting in the uniform expansion of the stent. The eluting sheath can be loaded with at least one therapeutic drug for the release thereof at a treatment site to facilitate repair of a damaged vessel. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen.

  • Patent number: 7316709
    Abstract: This invention is directed to a balloon catheter having at least one advancement wire with a distal end section secured to a distal tip section of the catheter, and with a textured section extending along the outer surface of at least a portion of an inflatable section of the catheter balloon. The textured section of the advancement wire preferably improves the ability of the balloon to remain in position in the patient's body lumen during inflation of the balloon to perform a medical procedure such as balloon angioplasty or stent touch-up.

  • Patent number: 7273495
    Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for treating an area of vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. A central section is positioned between distal and proximal sections and is aligned with the area of vulnerable plaque to enhance growth of endothelial cells over the fibrous cap of the vulnerable plaque to reinforce the area and reduce the likelihood of rupture.
