International Classification:

A61M029/00

US Classification:

606200000

Abstract:

A thrombosis filter which can be securely affixed at a selected location in the vascular system of a patient and removed when no longer required. A first embodiment of the thrombosis filter includes a plurality of struts having a first grouping and a second grouping. The first grouping of struts and the second grouping of struts radiate in opposite directions. The free ends of the struts include anchoring elements which anchor into the walls of a blood vessel. At least one grouping of struts is comprised of a shape memory material. When these struts are at body temperature, their free ends engage the wall of the blood vessel. When the temperature of the shape memory alloy struts is selectively varied from body temperature, the struts retract into the body portion of the thrombosis filter. A second embodiment of the thrombosis filter includes a generally cylindrical anchoring portion, and a generally conical filtering portion, the filtering portion includes a plurality of elongated strands interwoven to create a pattern of cells. These strands extend beyond the filtering portion to comprise the anchoring portion. These strands are made of a shape memory material. At body temperature, the thrombus filter takes on an expanded shape. At a temperature other than body temperature, the thrombus filter assumes a contracted shape. When the thrombus filter assumes a contracted shape, the anchoring portion retracts away from the walls of the blood vessel. A method is also disclosed for removing the thrombus filter from a blood vessel. The method comprises changing the temperature of the thrombus filter so that it assumes a retracted shape then pulling the thrombus filter inside the lumen of a retrieval catheter.

International Classification:

A61B 10/00

US Classification:

600565000, 600564000

Abstract:

Embodiments of the invention are directed to a medical device and methods for collecting a tissue sample from a patient's body. The device may include a first tube defining a lumen and an aperture at a distal end of the first tube. A second tube extends within the lumen of the first tube and defines a lumen and slots, where at least some of the slots have sharp edges configured to shear tissue. The second tube is movable relative to the first tube such that the sharp edges cut a plurality of samples from tissue disposed within the aperture.

US Classification:

604 9504, 604524

Abstract:

A medical device for advancement over a guidewire includes a number of lumens therein including a working channel lumen, one or more control wire lumens, and a guidewire lumen. A flexible support within the device includes a number of interlocking elements that resist longitudinal compression, transfer rotational torque, and can bend side to side. The flexible support also includes a slot that is aligned with the guidewire lumen. An outer jacket includes a perforation, slot, slit, or thinned area that is aligned with the slot in the support member and the guidewire lumen in order to allow a device such as a guidewire to be removed from the guidewire lumen and through the support member.

US Classification:

600565

Abstract:

An echogenic needle aspiration device. In one embodiment, the device includes an echogenic needle, the needle including a tubular sidewall having a non-circular transverse cross-section over at least a portion of its length. The non-circular cross-sectional shape of the needle may be provided, for example, by radially spacing one or more straight, longitudinally-extending fins, ribs or other projections about the periphery of the needle and/or by providing the needle with a polygonal cross-sectional shape.
