摘要: A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted and to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.

摘要: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.

摘要: A filter with translating hooks is described. The filter can include strut members having first and second struts connected by a connecting portion. A translating hook is disposed adjacent the connecting portion of the strut members, the hook including a first elongate member attached at one end to the first strut and a second elongate member attached at one end to a second strut, the opposite ends of the elongate members connected together to define a tip. The translating hooks are configured to bend toward a central axis of the filter when the filter is in a collapsed configuration for delivery to a blood vessel and recovery from a blood vessel, and away from the central axis of the filter when the filter is in an expanded configuration within a blood vessel such that the hooks engage a vessel wall.

摘要: Devices for and methods of closing a patent foramen ovale (PFO), thus reducing or eliminating blood flow through the defect The device is formed from a tubular structure having split ends, such that, after insertion, struts defined by the split ends pivot in a radial direction away from the tube, thereby securing the device within the septal defect. Methods include inserting the device as a tubular structure into the PFO and causing the struts to extend radially away from the central axis of the device.

摘要: A blood filter device for placement in a blood vessel including a plurality of anchor members disposed radially and extending angularly about a first hub. A filter basket is preferably positioned upstream from the anchor members. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The filter basket is made up of a number of filter members configured to retain blood clots within the basket without completely blocking blood flow or applying additional force to vessel walls. Portions of the filter members may project radially outward to position the basket near the vessel centerline, but the filter basket preferably does not include hooks or anchors for anchoring the filter basket to the blood vessel.
