    摘要: A sensor is disclosed, for implantation within a blood vessel to monitor a substance in or property of blood. In one embodiment, the sensor is retrievable. In another embodiment, the sensor has a layer that minimizes the formation of thrombus. A signal representative of the substance in or property of blood is transmitted to an external receiver. In another embodiment, the sensor detects nitric oxide or a nitric oxide metabolite and can be implanted for a period of hours, days, weeks or years. Methods are also disclosed.

    摘要: A retrievable medical filter which can be placed in a blood vessel or other body passage. The filter has improved structural features for enhancing its filter effectiveness and to facilitate its retrieval from the body passage. The filter has a longitudinal spine with struts extending from each longitudinal to form filter baskets. The ends of the spine to which the struts are attached may be rings with serpentine cuts in the rings to make them expandable. The struts can extend circumferentially as well as radially outwardly to provide a structure which can be radially compressed without bending the struts in a tight radius.

    摘要: A sensor is disclosed, for implantation within a blood vessel to monitor a substance in or property of blood. In one embodiment, the sensor detects nitric oxide or a nitric oxide metabolite. In another embodiment, other substances such as glutamate, aspartate, arginine, citrulline, acetylcholine, calcium, potassium, or dopamine are monitored. The sensor may be attached to a support structure such as a stent, guidewire, or catheter. In a further embodiment, a catheter is disclosed that extracts patient fluid to a sensor outside the body for monitoring a substance or property of the patient fluid. Methods are also disclosed.

    摘要: A medical sheet has an intricate pattern of loops, struts and bridges and is made of a super elastic alloy. The medical sheet includes a plurality of amorphic circles which provide rounded surfaces attached to the outer edges which made the medical sheet a-traumatic when implanted. When the medical sheet is cooled the molecular phase becomes martensitic which allows the medical sheet to be compressed for easier insertion into a patient. When the medical sheet is heated, the molecular phase changes to austenitic which causes the medical sheet to expand to a size suitable for implantation. The medical sheet can be secured within the patient by suturing through holes in the amorphic circles.
