  • Patent number: 9533127
    Abstract: A method that includes introducing a catheter assembly to an obstructed region of a blood vessel lumen and recanalizing the obstructed region with the catheter assembly is disclosed. Prior to or during recanalization, a treatment agent may be delivered through the catheter assembly to a vessel region downstream to the obstructed region. The treatment agent may have a property that will inhibit reperfusion injury. Alternatively, a medical device may be introduced to an obstructed region of a blood vessel lumen and the obstructed region recanalized with the medical device. The treatment agent may be delivered to a vessel region downstream to the obstructed region. The treatment agent may include at least one of an immunosuppresant and an antioxidant.

  • Patent number: 8888675
    Abstract: Apparatus and methods are disclosed for supporting ischemic tissue of the heart using scaffolds that may be placed within the heart percutaneously. A scaffold assembly may include a layer of biocompatible material detachably secured to a placement rod, such that the placement rod may be used to urge the layer of biocompatible material through a catheter to adjacent an area of ischemic tissue. Anchors may secure the layer of material to the myocardium. Multiple layers of biocompatible material may be placed in the ventricle separately to form the scaffold. In some embodiments, a scaffold is formed or reinforced by injecting a polymer, such as a visco-elastic foam, around an inflatable member inflated within a ventricle.

  • Publication number: 20140199377
    Abstract: Disclosed are compositions with sustained-release carriers associated with at least two different types of growth factors and methods of fabrication and treatments thereof. In some embodiments, simultaneous release of the growth factors may be preferred while in other embodiments, sequential release of the growth factors may be preferred. Application of at least two growth factors to an injury site, e.g., compromised cardiac tissue caused by, for example, myocardial infarction or ischemic heart failure, may better mimic and induce the complex growth factor signaling pathways necessary to improve cardiac function. When applied to a patient after a myocardial infarction or ischemic heart failure, multiple growth factors within a sustained-release carrier platform or platforms may cause a synergistic effect on injected cells intending to alleviate left ventricle remodeling. Methods of treatment include percutaneous, sub-xiphoid, and open chest methods using catheters and/or syringes.
