  • Publication number: 20070250146
    Abstract: An improved stent-graft device is provided that delivers a smooth flow surface over a range of operative expanded diameters by applying a unique cover material to the stent through a technique that allows the cover to become wrinkle-free prior to reaching fully deployed diameter. The unique cover material then allows the device to continue to expand to a fully deployed diameter while maintaining a smooth and coherent flow surface throughout this additional expansion. Employed with a self-expanding device, when the device is unconstrained from a compacted diameter it will self-expand up to a fully deployed diameter with the graft being substantially wrinkle-free over diameters ranging from about 30-50% to 100% of the fully deployed diameter. Preferably, the graft component comprises an elastomeric material, such as silicone, polyurethane, or a copolymer of PAVE-TFE.

  • Publication number: 20070198077
    Abstract: A self-expanding stent-graft provided in a diametrically compacted state for implantation and retained preferably by a constraining sheath, useful for the temporary or permanent repair of injured, partially or entirely transected body conduits including blood vessels. It may be used under direct visualization to quickly stop or substantially reduce loss of blood from such damaged vessels and to quickly re-establish perfusion distal to the injury site. The device would typically be implanted under emergency room conditions but also be used in field situations by trained medical technicians. After an end of the device is inserted into a blood vessel through the injury access, deployment preferably initiates from the device end in a direction moving toward the middle of the length of the device by directionally releasing the constraining sheath.

  • Publication number: 20070167974
    Abstract: The present invention relates to a non-evertable blood filter that divides the transverse cross sectional area of a venous vessel into three annular regions or zones. The inner zone, the region immediately surrounding the longitudinal axis of the vessel, is maintained in a relatively open state with only minimal interference from the members making up the filter device so that blood flow can be maintained at a relatively normal rate. Concentrically surrounding the inner zone is the intermediate zone, to which captured emboli are directed out of the bloodstream passing primarily through the inner zone. Finally, concentrically surrounding the intermediate zone is the outer zone adjacent to the vessel wall.

  • Publication number: 20070093886
    Abstract: The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system that is an integral extension of the sheath. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. As the sheath retracts from around the endoluminal device, material from the sheath may be converted into deployment line. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device expands in configuration and repairs vascular or cardiac structures of an implant recipient. Any remaining sheath material is removed from the implantation site along with the deployment line.

  • Publication number: 20070088323
    Abstract: Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions.

  • Publication number: 20060198866
    Abstract: A medical device provided with at least a partial surface coating of a thermoplastic copolymer of tetrafluoroethylene and perfluoroalkylvinylether that is free of cross-linking monomers and curing agents. The fluoropolymer coating is preferably an amorphous thermoplastic, is highly inert and biocompatible, has elastomeric characteristics that provide desirable mechanical properties such as good flexibility and durability. These characteristics allow the coating to be considered “functionally transparent” because it withstands mechanical deformations required for the assembly, deployment, expansion, and placement of medical devices, without any adverse effect on the mechanical and biological functionality of the coated device. Further, its inertness, derived from the perfluorocarbon structure, contributes to its functionally transparent nature.

  • Publication number: 20060190071
    Abstract: An endoprosthesis expansion system having, in combination, a delivery component such as a length of catheter tubing having at its distal end an intermediate sheath component, and an inner tube within the full length of the delivery catheter and intermediate sheath component. The inner tube has a protrusion affixed to its distal end, and an expandable endoprosthesis is fitted in a compacted state about the intermediate sheath, immediately proximal to the protrusion. If the endoprosthesis is a self-expanding endoprosthesis (as is preferred), an exterior constraining sheath is required around the outer surface of the endoprosthesis.

  • Publication number: 20060015167
    Abstract: Large diameter self-expanding endoprosthetic devices, such as stents and stent grafts for delivery to large diameter vessels, such as the aorta, are disclosed having very small compacted delivery dimensions. Devices with deployed dimensions of 26 to 40 mm or more are disclosed that are compacted to extremely small dimensions of 5 mm or less, enabling percutaneous delivery of said devices without the need for surgical intervention. Compaction efficiencies are achieved by combining unique material combinations with new forms of restraining devices, compaction techniques, and delivery techniques. These inventive devices permit consistent percutaneous delivery of large vessel treatment devices. Additionally, small endoprosthetic devices are disclosed that can be compacted to extremely small dimensions for delivery through catheter tubes of less than 1 mm diameter.

  • Publication number: 20050131515
    Abstract: A removable device such as a stent-graft, intended for applications where it may be desirable to remove the device at some time following implantation. The stent-graft of the present invention includes a helically-wound stent component provided with a covering of graft material. It is removable by gripping an end of the helically-wound stent component with a retrieval device and applying tension to the stent component in the direction in which it is intended to be withdrawn from the site of implantation. The use of such a retrieval device allows the stent-graft to be removed remotely, such as via a catheter inserted into the body at a different location from the implantation site. The design of the stent-graft is such that the stent component is extended axially while the adjacent portion of the graft separates between windings of the stent component.

  • Publication number: 20050101989
    Abstract: An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of “radial” stiffness with a low degree of “longitudinal” stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter, the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced.
