  • Patent number: 9005269
    Abstract: Bioabsorbable self-expanding medical devices formed of an integral framework with a multiplicity of fenestrations are provided. The framework is continuous, non-filamentous, non-braided, and non-interlaced. The devices includes a non-blended hydrolysable co-polymeric material comprising an amorphous component with a glass transition temperature that is below ambient body temperature and a crystallizable component that possesses a crystalline melting point in excess of ambient body temperature. The devices radially expand from a compressed first diameter to an uncompressed second diameter equal to or greater than 1.5 times the first diameter within two minutes in an aqueous medium at 37° C. following release of a compressive force placed on the devices. Additionally, the medical device does not change axial length significantly as the radial dimensions of the devices are changed.

  • Patent number: 8996134
    Abstract: A highly flexible implantable lead that offers improved flexibility, fatigue life and fatigue and abrasion resistance improved reliability, effective electrode tissue contact with a small diameter and low risk of tissue damage during extraction. In one embodiment the lead is provided with both defibrillation electrodes and pacing/sensing electrodes. For defibrillation/pacing leads, the lead diameter may be as small as six French or smaller. The construction utilizes helically wound conductors. For leads incorporating multiple separate conductors, many of the helically wound conductors are arranged in a multi-filar relationship. Preferably, each conductor is a length of wire that is uninsulated at about the middle of its length to create an electrode, wherein the conductor is folded in half at about the middle of the length to create first and second length segments that constitute parallel conductors.

  • Publication number: 20140303711
    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: 20140277363
    Abstract: The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, a covering member disposed about the endoprosthesis, and at least one flexible element situated between the endoprosthesis and the covering member. The covering member can extend beyond an end of the endoprosthesis. In operation, as the covering member is removed, the flexible element can guide the covering member over the end of the endoprosthesis to prevent entanglement between the end of the endoprosthesis and the covering member.

  • Patent number: 8721819
    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.

  • Publication number: 20140105955
    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: 20140066897
    Abstract: The invention is directed to delivery medical devices that enable consistent “on-demand” delivery of therapeutic agents to a vessel. The medical device of the current invention comprises retractable sheath comprising neckable elements. The medical device of the current invention comprises an expandable member, a hydrophilic coating comprising at least one therapeutic agent about the expandable member or structural layer and a retractable outer sheath with a selectively permeable microstructure. The design and methods disclosed herein ensures that therapeutic agent delivery occurs essentially only during retraction of the outer sheath, minimizing coating and/or therapeutic agent loss to the bloodstream and providing controlled delivery to the treatment site.

  • Publication number: 20140039536
    Abstract: A medical device includes a balloon member, a port that couples a compartment interior of the balloon member to a region exterior of the balloon member, and a tubular member that defines a lumen. A distal end of the tubular member is attached to an internal surface of the balloon member within the compartment so that a portion of the internal surface of the balloon member provides a seal at a distal end of the lumen. The tubular member passes through the port, and the proximal end of the tubular member is configured to remain exterior of the compartment. A delivery of a sufficient amount of a filling material into the lumen of the tubular member causes a length of the tubular member to pass through the port and into the balloon compartment.

  • Publication number: 20130317601
    Abstract: The present invention is directed to a device that permits a permanent aperture to be formed in a wall, or other partition, of an implantable medical device. The present invention maintains the continuity and fluid-retaining properties of the implantable medical device by providing a breachable barrier material fully covering an opening delimited by a deformable framework. The invention is accessed with conventional interventional surgical instruments that disrupt and displace the barrier material. Following disruption of the barrier material, the opening is enlarged with surgical instruments to form a permanent framed aperture in the wall of the implantable medical device. The permanent framed aperture provides fluid communication across the wall of the implantable medical device.
