  • Patent number: 9138213
    Abstract: The disclosure is directed to a heart occlusion device and a method for occluding an aperture defect in a heart. The heart occlusion device includes two separate wires 12, 14. Each wire forms geometric shapes that together form a distal plate and a proximal plate. The first plate is disposed in a first plane. The second plate is disposed in a second plane that is parallel to and remote from the first plane. The distal plate and the proximal plate are separated by a self-centering waist. The proximal plate is attached to a hub. A similar hub is optional on the distal plate. The plates further include coverings which form a sealant to occlude an aperture in a tissue. The wires forming the plates have a shape-memory capability such that they can be collapsed and distorted in a catheter during delivery but resume and maintain their intended shape after delivery.

  • 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: 20070219618
    Abstract: The present invention is directed to an implantable medical device having two or more flexible framework elements helically disposed around a common central axis. Each framework element has a configuration having a series of apices alternating in direction. The framework elements are arranged together in the helical winding so the apices are in a nested relationship. Adjacent apices are connected to one another with flexible linkage elements. Each linkage element follows a distinct pathway or course through the framework elements. The elements can each be made of the same or different materials.

  • 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: 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: 20060118236
    Abstract: A prosthetic implantable device that offers a reduction in fluid loss when the device is punctured, such as by a dialysis needle or suture needle, and the needle is subsequently removed. The device may be made to be thin and flexible, and with longitudinal stretch, in order that it also offers good handling and kink resistance to a surgeon. While the device is preferably of tubular form, flat sheets or other forms may also be made. The device includes inner and outer layers of a porous material having a microstructure of nodes interconnected by bent fibrils, and having void spaces between adjacent bent fibrils. The inner and outer layers are joined by an elastomeric adhesive that may interpenetrate the void spaces of the adjacent surfaces of the inner and outer layers, that is, the inner surface of the outer layer and the outer surface of the inner layer.

  • 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.
