Abstract: A removable intravascular filter having a filtering configuration for capturing thrombi in a blood vessel and a retrieval configuration for removal from the blood vessel. The filter may be implanted in a patient's vena cava and may be removed from the vena cava through the patient's jugular or femoral vein. A method of removing an intravascular filter from a patient's vena cava through the patient's femoral vein is also provided.

Abstract: Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue. The medical device of the system may include a biasing strip engaged with the jaws, and/or a gripping strip attached to at least one of the jaws to improve the engagement of the tissue between the jaws.

Abstract: A biopsy stylet and needle system is provided that is configured for navigation and spring-loaded deployment through at least one tortuous or otherwise confined length. The system includes a needle cannula through which a notched biopsy stylet is disposed. The notched biopsy stylet includes at least one outer diameter length that is about the same as, but preferably very slightly less than, the inner diameter of the needle cannula. The notched biopsy stylet also includes at least one outer diameter length that has a smaller diameter, the lengthwise position of which corresponds to the tortuous or otherwise confined length through which the system is to be operated. The smaller stylet diameter length is configured to prevent binding between the stylet and the needle cannula and/or between the needle cannula and an overlying access cannula or other access passage structure.

Abstract: A fiducial deployment system may include one or more of a needle including a dimpled retention structure configured to releasably retain a plurality of fiducials, each of which includes a central aperture (which may be embodied as a groove or similar opening); a retention/deployment stylet that traverses through each fiducial's central aperture and releasably engages a distalmost fiducial of the plurality of fiducials with a splayed distal stylet end; a pusher cannula member; and echogenic dimpling and/or other echogenic-enhancing features on at least a distal portion of the needle.
