摘要： A medical catheter (1) for the transvascular deployment of a collapsible medical device such as a filter (2) has a tubular body formed by an inner tubular core (11) surrounded by an outer thin-walled tube (10) which is fixed to the core (11). The outer thin-walled tube (10) extends outwardly beyond a distal end (12) of the core (11) to form a fixed thin-walled medical device embracing pod (3). The filter (2) is carried on a guidewire (6) which is slidably engagable within a central lumen of the core (11) and the filter (2) can be collapsed against the guidewire (6) for loading within the pod (3). With the filter (2) thus loaded within the pod (3) the distal end of the catheter (1) can be manoeuvred through a patient's vascular system to a desired deployment site where the filter (2) is discharged from the pod (3) allowing the filter (2) to expand within the blood vessel for use filtering blood flowing through the blood vessel.

摘要： A delivery system for delivery and deployment of a self expanding stent 1 especially in an arterial vessel with a tortuous passageway leading thereto comprises a catheter shaft 9 with a distal sheath 6. An inner core 5 is fixed to a larger diameter outer core 10, the difference in diameter providing an abutment. To deploy the stent 1, the sheath 6 is drawn proximally relative to the inner core 5, the proximal end of the stent 1 is engaged by the abutment and the stent 1 expands as it is uncovered by the sheath 6. The system includes a stabiliser tube 25 to which the inner core 5 is fixed, at least during the deployment of the stent 1.

摘要： An embolic protection device (2000) comprises a collapsible filter body (102), a filter support (103) for supporting the filter body (102), and a tubular member (108) to which the filter support (103) is mounted. The filter support (103) comprises two round wires (116). Each wire (116) has a 'M'-shaped curve (120) in the wire (116) which acts as a strain distributing linking element. In an extended configuration, the concave portion of each curve (120) faces longitudinally in the distal direction. In a collapsed configuration, the concave portion faces radially inwardly towards the tubular member (108) and wraps around part of the tubular member (108) to define a compact, low-profile filter support (103). Tethers (500, 501) extend between the curves (120) and a sleeve (201) slidably mounted to the tubular member (108). The distal end of each tether (500, 501) is fixedly attached to the sleeve (201) and to the filter body (102). The sleeve (201) is slidable over the tubular member (108) between a pair of stops.

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 opposition with the vessel wall. The engagement segments define at least partially a substantially helical engagement track.

摘要： A collapsible filter element (105) for a transcatheter embolic protection device (100) comprises a collapsible filter body (30) 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 (105). A proximal inlet portion of the filter body (30) has one or more inlet openings (117) sized to allow blood and embolic material enter the filter body (30) and a distal outlet portion of the filter body (30) has a plurality of outlet openings (119) sized to allow through-passage of blood, but to retain embolic material within the filter body (30). The filter body (30) is at least partially of laminate construction comprising a membrane (31) coated with a coating (32, 33) which is biocompatible, the thickness of the coating (32, 33) being from 4% to 40% of the thickness of the membrane (31). The coating (32, 33) may be of hydrophilic material. To facilitate retrieval of captured embolic material the distal portion and/or an intermediate portion of the filter membrane (31) may be stretchable. The filter body (30) may have regions of varying hardness or stiffness.
