摘要： The present invention provides a septal defect closure device (10) having a first occluding disk (30) having a first flexible membrane (32) attached to a first frame (34) and a second occluding disk (20) having a second flexible membrane (22) attached to a separate second frame (24). The first frame has at least two outwardly extending loops joined to one another by flexible joints. These loops are attached to the first membrane to define taut fabric petals when the first disk is in a deployed configuration. A central portion of the first membrane is joined to the central portion of the second membrane via a joining segment, which may comprise a conjoint disk. The flexible joints of the first frame are received within the joining segment. This septal defect closure device provides enhanced retrievability.

摘要： A distal protection device for use in a body lumen includes a functional element, which may be a filter or an occlusive element. The device includes a first elongate member, a second elongate member carried by the first elongate member, and the functional element carried by the second elongate member. Motion of the first elongate member can be independent of the motion of the functional element.

摘要： An intravascular medical device including an elongated member configured to be advanced along a vascular path of a patient, the elongated member having opposite first and second ends, the first end and second ends both being adapted for intravascular insertion, and the first end having a different structure than the second end. The elongated member has sufficient flexibility to be advanced through a human vasculature. Preferably, the first and second ends are adapted to have different operating characteristics. Depending on the operating characteristics needed for a particular procedure, a physician can insert either the first end portion or the second end portion of the elongated member into the patient's vasculature.

摘要： Catheters, assemblies, and methods for delivering and recovering embolic protection devices. Catheters are provided that can be advanced over single length guide wires and which can be retracted over single length wire shafts of distal embolic protection devices. One catheter is a two-port catheter having two sidewall ports, a distal end port, and a proximal end port. The two-port catheter can be advanced over a guide wire threaded between the distal end port and the distal sidewall port. An embolic protection device wire shaft can be back loaded into the distal end port and out the proximal sidewall port. A three-port catheter includes a distal end port, and distal, intermediate, and proximal sidewall ports. The distal sidewall port can be dimensioned to accept passage of a filter body through the port. The distal end port can be dimensioned to accept only a guide wire to provide a smooth transition from the guide wire to the small profile distal end. The guide wire can extend between the distal end port and the intermediate port while the filter body shaft can extend through the proximal port, to be distally urged through the distal sidewall port. Another catheter embodiment is a slotted catheter, including a biased, normally open slot over most of its length. The slot can be sufficiently small to resist unwanted transverse movement of a wire through the slot. The slotted catheter can be retracted over a wire by forcing the wire through the resilient slot.

摘要： A collapsible medical device that includes a mandrel having a distal end and a stop spaced proximally of the distal end. A proximal length of the mandrel extends proximally of the stop and a distal length of the mandrel extends distally of the stop. A functional element has a radially expandable body and includes proximal and distal sliders. The proximal and distal sliders are slidable along the mandrel independently of one another such that the distance between the proximal slider and distal slider can be varied to effect different configurations of the functional element. In one method of using such a device, urging the mandrel distally causes the stop to exert a distal biasing force on the distal slider, which acts against a restorative force of the functional element to axially elongate the functional element and reduce friction between the functional element and a wall of the vessel.

摘要： An embolic protection device or system for use in a lumen of a vessel in a patient's vascular system. The device filters debris and blood clots in a body lumen and/or prevents them from moving distally from a treatment site in a vessel and causing emboli. The device may include a filter placed distally of the treatment site. The device may include an occlusive element placed either distally or proximally of the treatment site.
