    摘要： The present invention is a temporary intraluminal filter guidewire for use during interventional procedures, such as angioplasty or stent deployment. A braided filter is mounted near the distal end of a steerable guidewire, which guides a therapeutic catheter. An actuator rod slides over the guidewire and is removably connected to the filter. The rod controls relative displacement of the filter ends, causing transformation of the filter between a deployed configuration and a collapsed configuration. Wire having enhanced radiopacity is included in the filter to provide visualization under fluoroscopy.

    摘要： A device and method for treating cardiac valve regurgitation. The device includes a tubular member including a lumen there through and a locking mechanism and a compression device carried on the tubular member. The compression device is transformable to a compression configuration in response to axial displacement and is locked in the compression configuration by the locking mechanism. The method includes positioning the compression device adjacent a cardiac valve and applying an axial displacement to the compression device to transform the compression device into a compression configuration and locking the compression device in the compression configuration to apply a compressive force to the cardiac valve.

    摘要： The present invention is a temporary device for capturing and removing embolic material during interventional procedures, such as angioplasty or stent deployment. A self-closing, tubular capture element, which may be either a filter or an occluder, is mounted near the distal end of a guidewire. The guidewire is capable of guiding a therapeutic catheter. Relative displacement of the capture element ends causes transformation of the capture element between a closed configuration and a deployed configuration that spans the vessel to be treated. A latch fixed to the guidewire temporarily retains the capture element in the deployed configuration. A first hollow rod slides over the guidewire to deploy the capture element and engage the capture element proximal end with the latch. A second hollow rod slides over the guidewire to release the latch and close the capture element.

    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.
