摘要： In vivo positionable filtration devices are provided that filter one or more therapeutic agents in blood flowing in a blood vessel. The filtration devices include an elongated member and a filtering component coupled to the elongated member. The elongated member and the filtering component are dimensioned for positioning within the blood vessel. Further, the filtering component includes a filtration material to filter the one or more therapeutic agents from the blood. Methods of in vivo filtration of the one or more therapeutic agents are also provided. The methods include positioning a filtration device of the filtration devices in the blood vessel, and administering a therapeutic agent of the one or more therapeutic agents upstream from a target tissue site to direct flow of the therapeutic agent to the target tissue site and then to the filtration device. The filtration device is positioned downstream from the target tissue site.

摘要： A method is disclosed for removing a vascular occlusion, such as a clot, from a blood vessel. A tubular sheath is inserted into the vessel and a self-expanding Nitinol mesh filter is deployed from a distal end of the tubular sheath at a location proximal to a clot. An inner catheter is advanced through the tubular sheath and through the mesh filter for contacting the clot. An expandable agitation element is provided along a distal end portion of the inner catheter for cutting or chopping the clot, thereby facilitating removal of the clot and improving blood flow through the vessel. Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs.

摘要： An inferior vena cava filter (340) for use in the inferior vena cava (4) to capture thrombus (8) passing through the inferior vena cava (4) towards the heart and lungs to prevent pulmonary embolism comprises a proximal support hoop (302), a distal support hoop (312) and a plurality of support struts (303) extending between the proximal support hoop (302) and the distal support hoop (312). The filter (340) also comprises a plurality of capture arms (121) which are movable from a capturing configuration to an open configuration. The capture arms (121) are biased towards the open configuration. A biodegradable suture holds the capture arms (121) in the capturing configuration.

摘要： A filter having a first set of members and a second set of members defining a trap sized to fit into a blood vessel. Each of the first and second members are configured to resiliently extend from the trap. At least one of the first set of members includes a first surface for engaging the vessel wall such that the at least one of the first set of members resists downstream movement within the vessel. At least one of the second set of members includes a second surface for engaging the vessel wall such that the at least one second member resists upstream movement within the vessel.

摘要： A method of preparing a filter for delivery into a body vessel. The filter includes a hub disposed along a longitudinal axis and a plurality of anchor members extending from the hub. Each anchor member includes either a cranial extension or a caudal extension at a distal end thereof. At least one anchor member distal end may be spaced from the hub at each of a first, second, and third distance along the longitudinal axis. The filter also includes a plurality of locator members extending from the hub, the locator members alternatingly interposed between the anchor members.

摘要： A medical device to be inserted into a blood vessel for effectively removing an object flowing in a biological lumen while reducing the burden on the living body includes an elongated shaft portion, and an expansion portion which is an elastically deformable cylindrical body having a plurality of gaps and in which a proximal portion or a distal portion of the cylindrical body is interlocked with the shaft portion. The expansion portion has a ring-shaped or annular bent portion which protrudes toward a proximal side position radially outside the expansion portion in a bent state of being bent along an axial direction, and an axial length of a second portion from the bent portion to a proximal end of the expansion portion is shorter than an axial length of a first portion from the bent portion to the distal end of the expansion portion.
