  • Publication number: 20110315305
    Abstract: A method for making a radially expandable stent-graft, including positioning a radially expandable stent member concentrically over a first polymeric member, locating a second polymeric member concentrically over the stent member and first polymeric member, and joining the first polymeric member to the second polymeric member through interstices of the stent member at selective locations to form slip planes between the first and second polymeric members. The slip planes accommodate movement of the stent between the polymeric members to facilitate compression of the stent graft to a low profile.

  • Patent number: 8012194
    Abstract: An endoluminal prosthesis including a first polymer member bonded to a second polymer member to selectively encapsulate a stent. Selective bonding between the first and second polymer members results in unbonded regions or pockets that accommodate movement of the stent, permitting compression of the prosthesis using minimal force and enabling collapse of the prosthesis to a low profile. The pockets are believed to encourage enhanced cellular penetration for rapid healing and may contain bioactive substances.

  • Patent number: 7887580
    Abstract: An endoluminal prosthesis including a radially expandable frame and an anchoring member. The anchoring member includes a first arm attached to a first strut of the frame and a second arm attached to a second adjacent strut of the frame. The first arm is joined to the second arm to form a vessel engaging end that, together with at least a portion of the first arm and second arm, is directed toward a central axis of the frame in the frame's collapsed configuration.

  • Publication number: 20090299403
    Abstract: A filter with translating hooks is described. The filter can include strut members having first and second struts connected by a connecting portion. A translating hook is disposed adjacent the connecting portion of the strut members, the hook including a first elongate member attached at one end to the first strut and a second elongate member attached at one end to a second strut, the opposite ends of the elongate members connected together to define a tip. The translating hooks are configured to bend toward a central axis of the filter when the filter is in a collapsed configuration for delivery to a blood vessel and recovery from a blood vessel, and away from the central axis of the filter when the filter is in an expanded configuration within a blood vessel such that the hooks engage a vessel wall.

  • Patent number: 7122050
    Abstract: A delivery mechanism for an implantable stent which provides a high mechanical advantage to the surgeon and convenient operation so as to facilitate smooth withdrawal of an outer catheter sheath following placement of the stent in the desired location within the patient's vessel. Preferred embodiments include a moving rail actuated by a V-shaped lever, a hydraulic actuator, a rack and pinion drive, and a power screw system. The delivery mechanism has a movable member that is attached to the outer catheter sheath so that actuating the mechanism results in an incremental movement of the moveable member, which in turn results in an incremental movement of the outer catheter sheath. Once the outer catheter sheath is retracted from the stent, the stent is deployed into the patient's vessel and the remaining parts of the mechanism, including an inner tube, an atraumatic tip, and a stabilizing element, are easily removed.

  • Patent number: 7004966
    Abstract: An endoluminal vascular device having a plurality of predetermined boding locations between respective first and second covering members to selectively encapsulate a support member. Selective bonding between the first and second covering members results in unbonded slip pockets to accommodate movement of the support member. Such a configuration allows compression of the support member with minimal force and also promotes a low profile of the compressed device. Unbonded regions of the covering members also encourage enhanced cellular penetration for rapid healing and can be configured to hold bioactive substances that diffuse through the covering members.

  • Patent number: 6547814
    Abstract: A method for selectively bonding layers of polymeric material, especially expanded polytetrafluoroethylene (ePTFE), to create endoluminal vascular devices. In a preferred method the selective bonding is achieved by applying pressure to selected areas using a textured mandrel. This permits a stent device to be encapsulated between two layers of ePTFE with unbonded slip pockets to accommodate movement of the structural members of the stent. This allows stent compression with minimal force and promotes a low profile of the compressed device. Unbonded regions of ePTFE allow enhanced cellular penetration for rapid healing and can also contain bioactive substance that will diffuse through the ePTFE to treat the vessel wall.

  • Patent number: 5332487
    Abstract: A method of and an apparatus for the electroplating of material onto substrates, such as computer memory disks, by use of a plating cell comprising cathodes, anodes, passive shields, filters, an oscillation system and an electrical power supply. Anodes and magnets are attached to the inside side walls of the plating cell. The magnets have a coating of an electrically nonconducting material covering it. Shields, each having a filter attached to it, are also fixed to the inside side walls. A pallet, having openings for holding disk substrates during electroplating, is placed between the shields in the plating cell. The disk substrates function as cathodes during electrolytic plating. The anodes and cathodes when electrically energized results in deposition of desired material, having uniform thickness, across the entire surface area of the substrate.
