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 filter retrieval catheter for retrieving an embolic protection filter (50) from a vasculature. The catheter comprises a catheter shaft (2) having a rapid exchange guidewire opening (4) in a sidewall of the catheter shaft (2) to facilitate rapid exchange of the catheter over a guidewire (5). To prevent buckling or kinking of the catheter shaft (2) in the region of the guidewire opening (4) during retrieval of the embolic protection filer (50), the catheter comprises two elongate reinforcement elements (6, 3) extending along the catheter shaft (2). The first reinforcement element (6) comprises an elongate wire element extending from a proximal end located proximally of the guidewire opening (4) to a distal end located distally of the guidewire opening (4). The second reinforcement element (3) comprises an elongate tubular element extending from a proximal end located adjacent to and distally of the guidewire opening (4) to a distal end (9) located further distally of the guidewire opening (4). The tube (3) tapers distally radially outwardly adjacent to the distal end (9). This tapered part (9) of the tube (3) is fixedly attached to the interior surface of the catheter shaft (2).

摘要： In a method for filtering embolic material, a guide catheter (5) is advanced through a vasculature. A delivery catheter (4), a guidewire (2) and a collapsed filter are advanced together through the guide catheter (5) to a point distally of the distal end of the guide catheter (5). The guidewire (2) is then advanced across the lesion. During this advancement of the guidewire (2), the delivery catheter (4) and the collapsed filter remain substantially stationary. When the guidewire (2) has crossed the lesion, the delivery catheter (4) and the collapsed filter are then advanced across the lesion until the collapsed filter is distal of the lesion. The delivery catheter (4) is then withdrawn to facilitate deployment of the filter at the location distal of the lesion to ensure that any embolic material released during performance of an interventional procedure at the lesion will be captured and safely retained within the filter.

摘要： A catheter 100 for delivery or retrieval of an embolic protection filter 101 has a distal pod 102 to house the filter 101. The filter 101 is deployed by means of an inflation balloon or sac 103 and the catheter has a proximal stop 104 for the sac. A proximal catheter shaft 106 has an inflation lumen for inflating the sac 103 from a delivery retracted configuration to a longitudinally extended configuration to deploy the filter 101. A transition mid section shaft 109 extends proximally from the pod 102 and defines a rapid exchange exit port 105 for a guidewire 107.

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： A catheter 1 suitable for advancement through a body passageway of a patient. The catheter 1 comprises a catheter body 4 which is flexible to provide the necessary trackability for the catheter 1 to advance through a body passageway, and two stainless steel reinforcement wires 5 extending along the catheter body 4 which provide the necessary pushability to advance the catheter 1 through the passageway. The reinforcements 5 are positioned diametrically opposed to one another by approximately 180 degrees on opposite sides of the longitudinal axis of the catheter 1, and the catheter body 4 is relatively soft and twistable. This configuration enables the entire catheter 1 to spontaneously twist during advancement so that the reinforcements 5 orientate themselves along a plane of neutral bending during advancement of the catheter 1. In this way, any resistance to the trackability of the catheter 1 due to the stiff reinforcements 5 is minimised.

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.
