  • Publication number: 20140222132
    Abstract: An endoprosthetic device for treating abdominal aortic aneurysms using suprarenal fixation. A stent ring is anchored in an area above the renal arties using self-flaring barbs that project during the nitinol expansion process. Sutures extend from the stent ring to an area below the renal arties to a bifurcated trunk portion comprising a nitinol fabric on a non-kinking frame. The bifurcated trunk is sealed proximal the iliac arteries and includes iliac leg holders having self-flaring retention struts for non-traumatic holding of iliac leg prosthetics. Suprarenal fixation and collapsible cells having retention projections and barbs that only flare during the nitinol expansion process assist in lowering the devices profile and sheathability for percutaneous delivery and may provide for recapturing the anchored device.

  • Patent number: 8777984
    Abstract: A device and method for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The deployment device has a first tubular structure having proximal and distal ends. A second tubular structure is substantially coaxial to and slideably engaged within the first tubular structure. The second tubular structure has a first substantially linear shape when constrained within the first tubular structure, and a second curvilinear shape when telescopically extended from the distal end of the first tubular structure. A third tubular structure is substantially coaxial to and slideably engaged within the second tubular structure. The third tubular structure is configured to provide sufficient rigidity to push the mechanical closure device from the distal end of the second tubular structure, and provide sufficient flexibility to assume a curvilinear shape when deflected by the second tubular structure.

  • Patent number: 8728026
    Abstract: Devices and methods for their use in increasing the aortic valve flow of a stenotic aortic valve are provided. The subject devices include an aortic valve isolation element and an aortic valve flushing element. The aortic valve isolation element is made up of a ventricular side aortic valve occlusion element, coronary ostia occlusion elements and an ascending aorta occlusion element. The aortic valve flushing element is made up of a dissolution fluid introducing element and a fluid removal element. In practicing the subject methods, a stenotic aortic valve is first isolated. Next, the isolated valve is flushed with a dissolution fluid, e.g., an acidic dissolution fluid, for a period of time sufficient for the aortic valve flow of the treated valve to be increased. In certain embodiments, the valve is also contacted with a dissolution fluid attenuating fluid, e.g., a buffer, during the flushing step in order to limit the contact of non-valve tissue with the dissolution fluid.

  • Publication number: 20140081370
    Abstract: The present invention generally relates to medical devices, particularly to a SDS (stent delivery system) that incorporates a spring stent stop. The delivery system, owing to a novel stent stop construction, can be assembled, with the crimped stent in place within the outer sheath of the device, to enable the device to be assembled with considerably greater efficiency by eliminating processes and component(s).

  • Patent number: 8663541
    Abstract: The present invention relates to a medical device and method of forming the medical device. In particular, the present invention relates to a medical device having a tubular membrane structure over a radially expandable structural frame, and to a method of forming the tubular membrane on the radially expandable structural frame. In one aspect, a structural frame is placed over a spinning mandrel and a fiber is electro-statically spun over at least a portion of the structural frame forming a membrane. A transfer sheath may be used between the mandrel and structural frame to prevent the electro-statically spun fiber from adhering to the mandrel. In another aspect, a first membrane is spun over the mandrel before the structural frame is placed over the mandrel. In this aspect, at least a portion of the structural frame is sandwiched between the membranes. The membrane or membranes and structural frame form a fiber spun frame assembly. The fiber spun frame assembly may be coated with an elastic polymer.

  • Patent number: 8518052
    Abstract: The present disclosure concerns a delivery system for delivering a medically useful payload through the vasculature to a site of interest in the patient's body. The medically useful payload may be a therapeutic device, such as a stent, and it may be a diagnostic tool, such as an imaging device. Owing to its structural attributes, the presently-inventive delivery system is well suited for carrying medical payload to and through vessel curvature and to branched regions (i.e., bifurcations) in same. Also, the device is well-suited to traveling through a vessel over a guiding element, such as a guidewire, which itself exhibits curvature.

  • Publication number: 20130204394
    Abstract: A tissue repair matrix has an intricate pattern of loops, struts and bridges and is made of a super elastic alloy. The repair matrix includes hooks which improve the ingrowth when implanted and amorphic circles which provide rounded surfaces to the outer edges which made the repair matrix a-traumatic when implanted. When the repair matrix is cooled the molecular phase becomes martensitic which allows the tissue repair matrix to be compressed for easier insertion into a patient. When the tissue repair matrix is heated, the molecular phase changes to austenitic which causes the tissue repair matrix to expand to a size suitable for medical procedure.

  • Patent number: 8500683
    Abstract: Catheter systems and methods for their use in enhancing fluid flow through a vascular site occupied by a vascular occlusion are provided. The subject catheter systems include at least an aspiration catheter and at least one of a total occlusion insert catheter and a partial occlusion insert catheter, where the insert catheters are capable of being slidably moved in the lumen of the aspiration catheter. In practicing the subject methods, a surface of the vascular occlusion is flushed with an acidic dissolution fluid using the subject catheter systems for a period of time sufficient for fluid flow through the vascular site to be enhanced, e.g. increased or established. The subject catheter systems and methods find use in the treatment of a variety of different vascular diseases characterized by the presence of calcified vascular occlusions, including peripheral and coronary vascular diseases.
