  • Patent number: 9204882
    Abstract: A vasoocclusive coil is reinforced with a stretch resistant member to improve safety during retraction of the coil. The stretch resistant member is fixedly attached at one end to the vasoocclusive coil, and the other end of the stretch resistant member is detachably mounted to an elongated pusher member to allow for placement and release of the vasoocclusive coil within the patient's vasculature. The stretch resistant member may be formed from a therapeutic and/or bioactive non-metallic material to enhance the therapeutic properties of the vasoocclusive coil.

  • Publication number: 20090287166
    Abstract: A system and method in accordance with the present invention provides a infusion catheter that is flexible, has such a smooth traction and a low profile to minimize break up of the obstruction when crossing it, can access distal vasculature quickly, is easy to use and readily to be implemented in the conventional PCI. Another object is to provide a method that can be performed within a short period of time and employs the catheter described herein to infuse a therapeutic agent distally to the obstruction before it is removed as a means of reducing reperfusion injury, protecting distal vasculature and microcirculation, preserving myocytes, reducing infarct size and ischemic damages in the heart, brain, lung, liver, kidney and limb. Another object is to provide complementary feature options to the infusion catheter and the aspiration catheter to improve the speed and quality of the vessel clearance.

  • Publication number: 20090226600
    Abstract: A multi-step method of forming a coating on a substrate, such as a stent or graft, is disclosed. The steps of the method include treating the surface with a plasma formed at or near atmospheric pressure to form one or more active species on the surface until a desired surface density of the active species is formed, and exposing the treated surface to a selected gas or liquid under conditions effective to convert the active species to a stable functional group. The exposed surface may be contacted with a surface-modifying group under conditions effective to covalently attach the surface-modifying group to the functional group. Also disclosed is a substrate having a bioactive/biocompatible coating and/or a drug-releasable coating prepared by the method.

  • Patent number: 6159531
    Abstract: A multi-step method for surface modification of a medical device having at least one surface exposed to tissue and/or blood. The steps comprise a low temperature plasma treatment of the said surface to provide a plasma deposited layer having functional groups. A chemical treatment of the plasma deposited layer using multifunctional linkers establishes covalent bonds with the plasma deposited layer. A bioactive/biocompatible agent react with the multifunctional linkers so that molecules thereof are covalently bound to said surface.
