    摘要： A catheter arrangement is described that is arranged to permit a guide wire or other structure to be fed laterally from the region of an expandable working element. The catheter includes an elongate flexible tubular member and an inflatable structure carried by a distal portion of the flexible tubular member. The flexible tubular member has a guide wire lumen and at least one fluid supply lumen that is in fluid communication with the inflatable structure. The inflatable structure includes at least one, and preferably two, inflatable members (which may take the form of balloons). In the case of two inflatable members, the first and second inflatable members are radially spaced about the guide wire lumen such that at least one gap is formed between the inflatable members. With this arrangement, the distal end of a guide wire may be advanced through the guide lumen and out of a side opening such that the guide wire passes laterally between the first and second inflatable members. With such an arrangement, a guide wire passing out of the side opening in the region between the inflatable members can readily be directed into a second branch of a vessel bifurcation while the device is positioned in a first branch.

    摘要： A variety of methods are described that pre-condition a balloon used in a balloon catheter in order to increase its flexibility. Generally, the membrane that forms the balloon is crumpled in order to induce a large number of irregular crumples in the balloon. The crinkling of the balloon improves its flexibility and thus the flexibility of the catheter. Most typically, torsion and/or compression are applied to the balloon membrane in order to induce the crumpling. The described crumpling can be used to increase the flexibility of a balloon of a given strength in a variety of catheters, including angioplasty catheters and stent delivery catheters. In stent delivery catheters, the resulting crinkles also have the additional benefit of improving stent retention.

    摘要： Various improved catheter marking arrangements are described. In a first aspect of the invention, a first longitudinally extending radiopaque marker is positioned on the catheter. A second longitudinally extending radiopaque marker is positioned opposite the first marker at a rotational orientation that is approximately 180 degrees offset from the first marker. The second marker has a length that is sufficiently different from the first marker such that a surgeon utilizing the catheter in a surgical procedure would be able to readily differentiate the first and second markers in a fluoroscopic image based on their respective lengths in order to determine the rotational orientation of the catheter.In some embodiments, the catheter includes a lumen that has a side port that opens to a side of the catheter. The first marker is composed of a pair of axially aligned marker segments located on opposite ends of the side port. The length of the first longitudinal extending marker defined as an end-to-end length of the pair of axially aligned marker segments is longer than the length of the second marker. The markers may be formed from any suitable materials that can be clearly detected by an imaging system.

In one aspect, the disclosed subject matter provides an intraluminal scaffold having a generally tubular body with a lumen defined therethrough, the tubular body having a compressed condition for delivery and an expanded condition for implant within a vessel having a distended portion, at least a length of the tubular body configured to form an enlarged portion in the expanded condition to engage a wall of the distended portion of the vessel. Methods for fabricating and using the scaffold, methods for remodeling a vein, and methods of deploying a medical device in a vessel without negatively impacting the function of a valve of the vessel, are also provided.
