  • Patent number: 8518064
    Abstract: A method for occluding a body vessel in a patient to block or reduce blood flow therethrough includes puncturing a blood vessel wall at a proximal vessel entry site with a hollow needle and extending the needle through the proximal entry site into the vessel lumen. The needle is extended through the vessel lumen and extended through the vessel wall at a distal vessel exit site into the extravascular space surrounding the distal vessel exit site. An expandable biocompatible material, such as expandable extracellular matrix (ECM) material, is then ejected though the distal end of the needle into the extravascular space. Then, while continuing to eject the expandable biocompatible plug material, the distal end of the needle is retracted back through the distal vessel exit site into the vessel lumen, such that the plug material continuously extends between the extravascular space surrounding the distal vessel exit site into the vessel lumen.

  • Patent number: 8512376
    Abstract: An apparatus and method for surgically reducing and internally fixing a shoulder acromioclavicular joint dislocation are disclosed. The apparatus preferably comprises a button and a washer, the washer being flexibly secured to the coracoid process of the scapula by means of a bone screw, the button and washer being secured together by means of a first suture. A second suture is provided secured between the button and a needle, such that the needle and associated button, may be advanced through a hole drilled through the clavicle, wherein the button and the washer may then be tightened, reducing the coracoclavicular distance, by means of the first suture connected therebetween, to reduce and hold a desired acromioclavicular joint dislocation.

  • Patent number: 8348999
    Abstract: The present invention satisfies the long felt need for a more compact and durable valve which may be formed in situ. The present invention provides a self-deployable valve system, a method of delivery, and a method of manufacturing for the self-deployable valve system. The present invention delivers the necessary components for forming a complete valve system in situ. The collapsed subcomponents of the system lack any functional characteristics commonly associated with a valve before being expanded. However, once expanded, the system is transformed into a competent valve for use in a wide variety of applications.
