摘要： A medical guidewire assembly comprises a guidewire (30) having a flexible tip (32). A medical device such as a collapsible filter (31) for use as an embolic protection device is mounted on the guidewire (30). The filter (31) is advanced through a body lumen with the guidewire tip (32) extending distally. At a first location the filter (31) is advanced relative to the tip (32) to a location which is distally advanced from the first location. Placement of the filter (31) in an optimal distal location is thereby achieved.

摘要： An embolic protection device 100 comprises a collapsible filter element 105 for delivery through a vascular system of a patient. The filter element 105 comprising a collapsible filter body 110 and a filter support frame 111 contacting the filter body 110 . The collapsible filter body 110 has an inlet end and an outlet end, the inlet end of the filter body having one or more inlet openings 117 sized to allow blood and embolic material enter the filter body 110 , the outlet end of the filter body having a plurality of outlet openings 119 sized to allow through passage of blood but to retain undesired embolic material within the filter body 110 . The filter support frame 111 is movable between a collapsed position for movement through the vascular system and an extended outwardly projecting position to support the filter body 110 in the expanded position. The frame 111 has a plurality of engagement segments which are spaced-apart longitudinally and transversely when the filter body 110 is in the deployed expanded configuration to urge the filter body 110 into apposition with the vessel wall. The engagement segments define at least partially a substantially helical engagement track.

摘要： A collapsible filter element for a transcatheter embolic protection device, the filter element comprises a collapsible filter body of polymeric material which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filer element. A proximal inlet portion of the filter body has one or more inlet openings sized to allow blood and embolic material enter the filter body. A distal outlet portion of the filter body has a plurality of generally circular outlet openings sized to allow through-passage of blood, but to retain embolic material within the filter body. The distal outlet portion of the filter body in the region of the outlet openings has means for reducing shear stress on blood passing through the outlet openings. The shear stress reducing means includes lead-in and lead-out radiussed portions of the filter body leading to the outlet holes. The porosity of the distal portion of the filter body decreases towards the distal end. A blind portion extends for at least 5% of the length of the body. Preferably there are between 200 and 300 outlet opening with an average diameter of approximately 150 microns.

摘要： A collapsible filter element (40) for a transcatheter embolic protection device (1). The filter element (40) comprises a collapsible filter body (41) which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filter element (40). A proximal inlet portion of the filter body (41) has two inlet openings (50) sized to allow blood and embolic material enter the filter body (41), and a distal outlet portion of the filter body (41) has a plurality of small outlet openings (51) to allow through-passage of blood, but to retain embolic material within the filter body (41). The filter body (41) is of an oriented polymeric material.

摘要： An embolic protection system (1) comprises a guidewire (99) for advancing through a vasculature, the guidewire (99) having a distal end and a proximal end; an embolic protection filter (1) having a filter body (41) with a distal end and a proximal end, the filter body (41) providing for a collapsed configuration and an expanded deployed configuration. The embolic protection filter body (41) has a guidewire path for slidably receiving the guidewire (99) to permit movement of the filter (1) relative to the guidewire (99) when the filter (1) is in the collapsed configuration and the expanded deployed configuration. A delivery catheter (2) is advanceable over the guidewire (99) for delivery of the embolic protection filter (1); the delivery catheter (2) having a proximal end and a distal end. The filter (1) deployed from the distal end of the delivery catheter (2) into the expanded deployed configuration. A retrieval catheter (3) is also advancable over the guidewire (99) for retrieval of the filter (1), the retrieval catheter (3) having a distal end and a proximal end; and engagement elements for engaging the embolic protection filter (1) with the guidewire (99) for retrieval of the filter (1) into the retrieval catheter (3) in the collapsed configuration.

摘要： An embolic filter having a filter support frame with a collapsed and an expanded configuration and a collapsible filter body supported by the support frame. The filter body has inlet and outlet ends. The filter body includes a proximal section having a longitudinally extending cylindrical shape and a distal section having a longitudinally extending conical shape that tapers in the distal direction. The support frame includes a plurality of alternating first segments such that, when the support frame is in the expanded configuration, the alternating first segments circumferentially extend in a first zigzag path to support the proximal, cylindrically shaped section of the filter body. The support frame includes a plurality of alternating second segments such that, when the support frame is in the expanded configuration, the alternating second segments circumferentially extend in a second zigzag path to support the proximal, cylindrically shaped section of the filter body.

摘要： A delivery catheter (1) has a distal pod (2) for reception of an embolic protection filter (3). The filter (2) is moved from a retracted delivery configuration to an extended deployed configuration by a push wire (6) which has an engagement hoop (7) at the distal end. Retraction of a handle (9) has the effect of retracting the pod (3) relative to the push wire (6) and the engagement hoop (7) and the filter (2) is effectively deployed by pushing it out of the pod (3).
