摘要： An embolic filter device and method of manufacturing the same are provided. The method includes reducing a wall thickness of a tube in a central region (18) between a proximal end portion (12) and a distal end portion (14) of the tube; cutting the proximal end portion of the tube to form an annular ring (32) at a proximal end of the proximal end portion; cutting a plurality of slits (25) ' in the central region; and expanding a portion of the tube between the annular ring and the distal end portion. The device includes a distal annular ring; a mesh connected to the distal annular ring; and a proximal annular ring connected to the mesh by at least two connecting portions.

摘要： A delivery catheter, for delivering an embolic protection filter through a vasculature over a guidewire, comprises a distal pod (1) which acts as a restraining sheath to restrain the embolic protection filter in a collapsed configuration during delivery. The pod (1) has a proximal portion (2), a distal portion (3) and a flared portion (4) intermediate the proximal portion (2) and the distal portion (3). The pod (1) comprises a layer (39) of an intractable material, such as polyamide, and a low coefficient of friction material layer (40), such as of polytetrafluoroethylene. Each layer (39, 40) is integrally formed and extends from the proximal portion (2) to the distal portion (3). A marker band (5) is mounted to the exterior surface of the proximal portion (2) to aid in visualisation of the pod (1).

摘要： A retrieval catheter (200) comprises a catheter shaft (2) and a retrieval catheter tip at the distal end of the shaft (2). The tip comprises an expandable tip body (201) and two reinforcement columns (6, 7) extending along the tip body (201) embedded within the tip body (201). The tip body (201) comprises a stiff, distal, radiopaque segment (203) and a soft, proximal segment (202). The distal segment (203) has a distal nose part (205) extending distally of the reinforcement columns (6, 7). Along the distal nose part (205), the wall thickness of the tip body (201) tapers distally from a smaller wall thickness to a larger wall thickness, and the internal diameter tapers distally from a larger diameter to a smaller diameter.

摘要： A retrieval catheter (1) comprises a distal tubular sheath (2) with a reception space (5) into which an embolic protection filter (10) may be retrieve. An elongate connector (10) extends proximally from the sheath (2) to allow a clinician to control movement of the sheath (12). The sheath (2) is backloaded over a procedural catheter such as a balloon catheter (20), for example for post dilitation of a stent (55). The procedure is more efficient and procedure time is reduced because a catheter system is provided which allows a procedural step to be carried out and a filter (50) to be retrieved.

摘要： An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through passage of blood but retain embolic material within the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body of the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced-apart stops (106, 120) on the guidewire (101) which allows some manipulation of the guidewire independently of the filter when the filter is in use. The filter element comprises between 200 and 500 outlet openings with an average dimension of between 50 and 200 microns. The openings are sized such that the shear stress imparted to blood moving through said filter element at physiological flow rates less than about 800 Pa.

摘要： A transcatheter occluder device (1) for closing an opening in a tissue wall for the repair of cardiac defects has a body (2) formed of an open cell polymer foam which will hold a desired occluder shape but is resiliently compressible for transcatheter deployment. The occluder device (1) has a pair of spaced-apart disks (4, 5) interconnected by a narrowed neck position (b). Voids within the foam body render it highly compressible and flexible. Grip means (7) mounted centrally in the neck portion (6) is releasably engageable by a guide wire for deployment of the occluder device (1) through a catheter at a defect.

摘要： A support (103) for an embolic protection device comprises round wires (116) which may form one or more support hoops for a filter body. The circumferential hoop formed by the wires (116) ensures that in the expanded position, the filter body (102) will be supported by the support frame (103) in circumferential apposition with the interior wall of the vasculature. The wires (116) may have a strain distributing linkage element in the form of a loop (120) in. The loop (120) acts as a diameter or circumference adjuster allowing an embolic protection device to adapt to different vessel contours and sizes whilst maintaining apposition with the vessel wall. The strain relieving geometry of the loops enhances the compliance of the bend points without creating a weakened hinge point, thus ensuring that there is no discontinuity in the circumferential seal against the vessel wall.
