  • Patent number: 9414843
    Abstract: Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures are used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the deployment of one or more vascular occlusion devices via a through-and-through percutaneous procedure that leaves the vascular occlusion device or devices in a through-and-through condition.

  • Patent number: 8226730
    Abstract: An implant is disclosed including a bio-compatible implant body that can be provided with a tip, or interconnected by one or more filaments. The implant body can be formed of a variety of biocompatible materials, including bio-remodelable materials such as small intestine submucosa. Methods are disclosed for assembly of the implant. Additionally, a method is disclosed for delivering the implant to a desired location in a patient.

  • Patent number: 8080260
    Abstract: A composition comprising a human- or animal-derived extracellular matrix and a macromolecular network which is prepared ex vivo is provided that is useful in the repair of a tissue injury, particularly in repair of tears or gaps between a tendon and a bone, such as in a rotator cuff tear. In an embodiment, the composition comprises a human- or animal-derived extracellular matrix having impregnated therein a macromolecular network of hyaluronan macromolecules that have been cross-linked via dihydroxyphenyl linkages, so that the cross-linked network is interlocked within the extracellular matrix. The resulting HA-incorporated extracellular matrix can be supplied in the form of a patch to reinforce a tissue repair or cover a tissue defect.

  • Patent number: 7766926
    Abstract: A sling for supporting a urethra in a patient has characteristics for resisting pull-out, roll-over and a combination of both pull-out and roll-over. To facilitate resistance to pull-out, sling material has protuberances or serrations to resist movement once placed in the patient by the surgeon. Improved resistance to roll-over or roll-up is achieved by providing relief on the sling in areas potentially subjected to roll-over forces by endopelvic fascia. The sling may be used on female or male patients, and may be used in conjunction with a wider support portion to support a bladder and a urethra, rather than a urethra alone. The sling may also be used to support other tissues within a patient.
