    摘要: A method and system to guide a medical device within a patient using image data, e.g., chemical image data, includes acquiring image data of a view region within the patient. A movable element of the medical device is guided, e.g., self-guided, based on the image data. For example, the image data may be analyzed to detect a target area within the view region, e.g., the target area having at least one characteristic that is different from other portions within the view region. The movable element may then be guided based on the detected target area.

    摘要: A wound dressing for use with exuding wounds includes (a) an outer vapor permeable layer permitting transpiration of fluid from the dressing; (b) an intermediate layer of hydrogel adapted for absorbing wound exudate; (c) a wound-contacting layer for separating the intermediate hydrogel layer from the wound; (d) wicking means associated with the wound-contacting layer for conducting exudate from the wound to the hydrogel; and (e) a therapeutic agent retained in the dressing by the wound-contacting layer.

    摘要: The present invention provides resistance to degradation from environmental stress cracking (ESC) and metal ion induced oxidation (MIO) for implantable, flexible pacing lead insulators having a body of polyether polyurethane elastomer material. A thin layer of a second polyurethane elastomer is applied as an overcoat to the lead insulator body. The second polyurethane is more resistant to ESC and MIO than the elastomer comprising the body of the insulator. Because ESC and MIO are surface phenomina, only a thin layer of the second material is required and the mechanical properties of the base material will determine the overall mechanical properties of the lead insulator.

    摘要: An apparatus designed to test blood, blood contacting biomaterials and devices such as materials and surface-modified materials; vascular grafts, stents, heart valves, catheters, leads, etc., for blood and material responses in vitro under physiological blood flow conditions. The apparatus consists of a stepper-motor driven circular disc(s), upon which a test vehicle, containing either the test materials, coating or device, is mounted. The test vehicle itself consists of a circular, closed-loop of polymer tubing containing a check valve.
