  • Publication number: 20150374517
    Abstract: Described are various embodiments of an improved endoprosthesis that includes a generally cylindrical graft portion that extends along a longitudinal axis to define a flow passage and a plurality of stent hoops. The plurality of stent hoops are connected to the graft portion and disposed in a spaced apart relationship along the longitudinal axis. There is at least a first suture disposed along on the outer surface of the main body. The first suture connects at least two of the spaced apart stent hoops together. The first suture also includes unidirectional barbs (or multidirectional barbs) configured to reduce movement of the main body with respect to a direction of blood flow in an artery.

  • Patent number: 9095370
    Abstract: This disclosure is directed to systems and methods for providing a guiding device having a dilatable, drilling tip. The tip is formed by wound helical members such that resistance to rotation in an unwinding direction dilates the tip. The helical members are configured so that the dilatable tip increases in stiffness when the helical members are tensioned by a resistance to rotation in the winding direction. In some embodiments, application of relative force between coaxial inner and outer tubular members is used to control the dilation, stiffness and drilling of the guiding member.

  • Patent number: 8945179
    Abstract: Described are method and device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The method includes locating a distal end of a closure device adjacent to the passageway. The closure device may include a closure line with proximal and distal ends, an expandable tissue anchor located along the distal end of the closure line, and an expandable occluder member located along the proximal end of the closure line. The expandable tissue anchor is deployed into tissue adjacent to the passageway. The expandable occluder member is deployed adjacent to the passageway such that the expandable occluder member substantially covers the second opening to the passageway.

  • Patent number: 8920449
    Abstract: This disclosure is directed to systems and methods for re-entering the true lumen of a vessel. The re-entry catheters employ deflectable struts to stabilize and support the distal tip in a subintimal location while a passageway back into the true lumen is formed. Re-entry to the true lumen can be effected with a cutting element or with a conventional guidewire.

  • Patent number: 8906085
    Abstract: In accordance with the present invention, there is provided a stent for insertion into a vessel of a patient. The stent has a front and back open ends and a longitudinal axis extending therebetween. The stent has a plurality of adjacent hoops that are held in alignment with the longitudinal axis between the front and back open ends by a thin film tube. The hoops are attached to either the inner or outer surface of the thin film tube. The stent is compressed into a first smaller diameter for insertion into the vessel with a delivery tube and a second larger diameter for deployment into the vessel. The inventive stent can be retracted into the delivery tube if it is improperly deployed.

  • Publication number: 20140358213
    Abstract: Various embodiments for a composite endovascular device (and variations thereof) that include an inner polymer structure and an outer thin-film shape memory structure. The inner polymer structure extends from a distal end to a proximal end along a longitudinal axis. The outer thin-film shape-memory structure has an inner thin-film surface coupled to the outer surface of the inner polymer structure from the distal end to the proximal end with a retrieval member at the proximal end to allow for the prosthesis to be retrieved after placement in a body vessel. The inner polymeric structure can be blended with a suitable bio-active agent or the agent can be loaded into the pores. The device can be permanent or temporary by virtue of being retrievable.

  • Patent number: 8876860
    Abstract: The present invention provides a porous structure that works very effectively to seal a puncture site with optimum porosity, absorbent capacity and perfect anatomical fit. The plug density and other fiber properties/geometry (total denier; number of filaments; etc) have provided an efficient structure that allows instantaneous absorption of blood during deployment. The final size of the plug with absorbed fluids provides an anatomical fit and seals the puncture site within few minutes after deployment.

  • Patent number: 8814900
    Abstract: A filter retrieval system for retrieving a previously implanted medical filter, and methods of using the retrieval system, are disclosed. The filter retrieval system has a flexible shaft, a retrieval element, and a handle with an actuator. The flexible shaft may be catheter-based, and has a proximal and a distal end, and has an opening near its distal end. The handle is affixed to the shaft near the proximal end of the shaft, and the actuator is adapted to manipulate the retrieval element to grasp or hook or otherwise engage a portion of the filter, and then pull the filter in through the opening into a passage or lumen of the catheter shaft. The retrieval system is capable of retrieving a filter in into a proximal and distal space defined by the flexible shaft, though only one space at a time.
