    摘要: A system for treating mitral valve regurgitation comprises tensioning device that can be deployed using a delivery catheter. The device includes tension member linking a proximal anchor and distal anchor. The device is constructed from a material having suitable elastic properties such that the device applies a constant tension force between the anchors, while stretching or flexing in response to a heartbeat when positioned across a chamber of a heart. The anchors may include a plurality of arms. In some embodiments, the arms may also flex in response to a heart beat. When positioned across the left ventricle of a heart, the device can reduce the lateral distance between the walls of the ventricle and thus allow better coaption of the mitral valve leaflets thereby reducing mitral regurgitation.

    摘要: A guiding catheter includes an elongate shaft with a main lumen and a pre-shaped curve adjacent the distal end of the shaft. The pre-shaped curve is sized and shaped for positioning in a main vessel to provide intubation of a branch vessel with a distal end of the catheter. An eccentric balloon is disposed on the shaft for selective inflation against a wall of the main vessel opposite the entrance into the branch vessel to provide supplemental backup support during interventional catheterization of the branch vessel. Methods of using the guiding catheter are also disclosed.

    摘要: A low-profile catheter valve includes a catheter, an elastomeric plug having a channel, and a hollow stem. The catheter has at least one stop extending into a central lumen of the catheter adjacent to the catheter's proximal end. The elastomeric plug is received within the central lumen of the catheter and seated against the stop. The hollow stem is slidably received within the central lumen of the catheter. An axial force applied to the elastomeric plug via the stem compresses the plug and closes the channel. The stem is maintained in a position within the catheter by an interference fit between the stem and the catheter.
