摘要： A method and apparatus are provided for withdrawing an indwelling over-the-wire catheter from an indwelling guidewire in which the guidewire is of a conventional length and is maintained in its indwelling position as the catheter is withdrawn. The position of the guidewire is maintained by constraining a segment of the catheter shaft and its included guidewire in a non-linear configuration such that the guidewire remains in its position as the catheter is withdrawn. The invention may be used to perform catheter exchanges without requiring the use of exchange wires, extension wires, rapid exchange catheters or special devices to connect the guidewire to the guide catheter.

摘要： The invention relates to a catheter device and method of use for exchanging a catheter having a full-length guidewire lumen over a conventional-length guidewire without the use of a guidewire extension or an exchange wire. The catheter device includes an elongated shaft defining an inflation lumen and a guidewire lumen extending longitudinally throughout its length, and a hydraulic exchange lumen extending from the proximal end of the shaft and terminating proximal the distal end of the shaft, wherein the hydraulic exchange lumen is in fluid communication with the guidewire lumen. A balloon is coupled to the distal section of the shaft and is in fluid communication with the inflation lumen. A flow guiding member is disposed within the guiding catheter and functions to redirect the distal flow of pressurized fluid traveling through the hydraulic exchange lumen in a proximal direction through the guidewire lumen.

摘要： A braided flange branch graft formed of a braided super elastic memory material includes a neck between an inner flange and an outer flange. The neck is positioned in a side opening in a sidewall of a main stent graft and the inner flange and outer flange are deployed on opposite sides of the sidewall. The inner flange and the outer flange have a diameter greater than a diameter of the side opening in the sidewall of the main stent graft. Thus, the sidewall of the main stent graft is sandwiched between the inner flange and the outer flange securely and simply mounting the braided flange branch graft to the main stent graft. The braided flange has a substantially unobstructed fluid communication passage therethrough. Further, when stretched into a substantially cylindrical shape for delivery, the braided flange branch graft has a small delivery profile and is extremely flexible.

摘要： A distal protection device captures debris during vascular procedures. In order to reduce the profile of the device, the thickness of the distal protection element is reduced in one or both of the end regions, either by reducing the thickness of filaments which form the distal protection element, or by removing portions of those filaments altogether. Various methods of reducing the thickness of the end regions and different profiles that can be created by the reduction are disclosed.
