  • Stents twisted prior to deployment and untwisted during deployment
    Patent number: 9592139
    Abstract: Stents can become twisted during deployment within tortuous vessels such that proper expansion against the vessel wall is inhibited. Stents can be twisted prior to deployment in a direction opposite the direction of twisting during deployment to facilitate full expansion of the stent against the vessel wall along the stent's entire length.

  • GALVANICALLY ASSISTED ANEURYSM TREATMENT
    Publication number: 20160279406
    Abstract: Treatment of an aneurysm or other vascular defect can be facilitated or enhanced by a galvanic cell formed by an implantable medical device configured to be implanted at or within the aneurysm or other vascular defect. The implantable medical device can include a primary structure including an anodic metal and a cathodic metal. The anodic metal and the cathodic metal each form a fraction of a total surface area of the primary structure. A galvanic cell formed by the anodic metal and the cathodic metal is configured to induce a galvanic voltage within blood for a duration of time to promote thrombosis. The thickness of the anodic metal can be less than or equal to 5 ?m, for example, to provide galvanic activity for between 5 and 30 minutes.

  • BIOPROSTHETIC TISSUE WITH REDUCED CALCIFICATION
    Publication number: 20160235528
    Abstract: A treatment for bioprosthetic tissue used in implants or for assembled bioprosthetic heart valves to reduce in vivo calcification. The method includes applying a calcification mitigant such as a capping agent or an antioxidant to the tissue to specifically inhibit oxidation in tissue. Also, the method can be used to inhibit oxidation in dehydrated tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the oxidation and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. In one method, tissue leaflets in assembled bioprosthetic heart valves are pretreated with an aldehyde capping agent prior to dehydration and sterilization.

    Publication number: 20150314042
    Abstract: A bioprosthetic tissue having a reduced propensity to calcify in vivo, the bioprosthetic tissue. The bioprosthetic tissue comprises an aldehyde cross-linked and stressed bioprosthetic tissue comprising exposed calcium, phosphate or immunogenic binding sites that have been reacted with a calcification mitigant. The bioprosthetic tissue has a reduced propensity to calcify in vivo as compared to aldehyde cross-linked bioprosthetic tissue that has not been stressed and reacted with the calcification mitigant.

  • PROSTHETIC HEART VALVE, SYSTEM, AND METHOD
    Publication number: 20150230922
    Abstract: Disclosed prosthetic valves can comprise a sewing ring configured to secure the valve to an implantation site. Some disclosed valves comprise a resiliently collapsible frame having a neutral configuration and a collapsed deployment configuration. Some disclosed frames can self-expand to the neutral configuration when released from the collapsed deployment configuration. Collapsing a disclosed valve can provide convenient access to the sewing ring, such as for securing the valve to the implantation site, as well as for the insertion of the valve through relatively small surgical incisions. Examples of delivery systems and methods for deploying the valves exhibit reduced patient trauma.

  • SELF-CINCHING SURGICAL CLIPS AND DELIVERY SYSTEM
    Publication number: 20150173759
    Abstract: A device and method for deploying self-cinching surgical clips. The device accesses at least two layers of tissue or material from only one side of the tissue or material and punctures through the two layers of tissue or material. The various configurations of clips disclosed herein are made of a superelastic material such as Nitinol, and have a constrained and a relaxed state, and no sharp edges or tips so as to reduce tissue irritation following deployment. The clip is disposed within the housing of the delivery device and held in a constrained state by a tube assembly until deployment wherein the clip assumes its relaxed state, where the ends of the clip are brought into close approximation, thereby securing the layers of tissue or material together.
