  • Patent number: 8137336
    Abstract: A steerable medical device is used to controllably introduce a guidewire or other medical instrument into a body of a patient and direct placement of the guidewire or other medical instrument in the body of the patient. The steerable medical device can include an elongated member, a steering mechanism, and an attachment member. The elongated member extends along a longitudinal axis and comprises a deflectable distal portion that is deflectable off of the longitudinal axis. The steering mechanism is adapted to control longitudinal and rotational movement of the elongated member and to control off-axis deflection of its deflectable portion. The attachment member is removably couplable to another medical device. The attachment member is moveably coupled to the steering mechanism and the elongated member.

  • Patent number: 7993390
    Abstract: Disclosed are implantable or insertable medical devices that provide resistance to microbial growth on and in the environment of the device and resistance to microbial adhesion and biofilm formation on the device. In particular, the invention discloses implantable or insertable medical devices that comprise at least one biocompatible matrix polymer region, an antimicrobial agent for providing resistance to microbial growth and/or a microbial adhesion/biofilm synthesis inhibitor for inhibiting the attachment of microbes and the synthesis and accumulation of biofilm on the surface of the medical device. Also disclosed are methods of manufacturing such devices under conditions that substantially prevent preferential partitioning of any of said bioactive agents to a surface of the biocompatible matrix polymer and substantially prevent chemical modification of said bioactive agents.

  • Patent number: 7947073
    Abstract: Bioresorbable medical implants are designed to have different resorption rates over time or over the topography of the implants. The resorption of the medical implants are controlled by including layers having differing resorption rates. The layers resorb sequentially over time through sequential exposure to body fluids. A resorption-controllable medical implant includes a series of two or more layers. The first layer includes a first bioresorbable material. The second layer includes a second bioresorbable material and resorbable particles of a first kind dispersed within the second bioresorbable material. Additional layers of bioresorbable material alone or including resorbable particles may be added to slow or speed resorption and achieve desired control over the resorption of the implant. Resorbable particles can be added in differing amounts or kinds in various segments of the implant to provide topographically differing resorption rates.

  • Publication number: 20110091519
    Abstract: The resorption of a medical implant can be controlled with the use of particles embedded in a resorbable bulk material forming the implant or portion thereof. The implant can be removed from a body of a mammal by natural biological mechanisms after use. The resorption of the implant can involve swelling and/or hydrolyzing of the particles within the implant upon contact with a body fluid such that porosity and flow of fluid within the bulk material of the implant is increased. Resorption of the implant may also involve the use of particles with magnetic properties embedded within the implant such that an applied magnetic field causes the particles to vibrate within the bulk material thereby increasing the porosity and thus the flow of fluid, hence facilitating resorption of the implant. The resorption rate of the implant can be controlled by modulating swelling, hydrolysis, or movement of the embedded particles.
