  • Publication number: 20060100665
    Abstract: Apparatus is provided for sealing a puncture in a blood vessel using at least one device that applies an internal compressive force upon a distal surface of the vessel. The devices preferably are deployable distal of the distal surface of the vessel, then retracted proximally to provide the internal compressive force, e.g., to promote coagulation and facilitate sealing of the puncture. Additionally, the devices of the present invention optionally may be used in combination with known techniques that provide an external compressive force upon an exterior surface of a patient's skin to expedite sealing of the puncture.

  • Publication number: 20060071371
    Abstract: A method for connecting a catheter balloon with a catheter shaft of a balloon catheter that improves the welding quality of a weld between the catheter balloon and the catheter shaft of the balloon catheter. Preferably, a welding energy absorbing device is arranged, preferably in the form of a coloured tubing, in the area of a fixation site after attaching a pre-fixation and then to irradiate this welding energy absorbing device with the radiation energy to carry out the welding. After the welding the pre-fixation and the welding energy absorbing device are removed.

  • Patent number: 6997951
    Abstract: A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

  • Publication number: 20050177228
    Abstract: An elongate body including a proximal and distal anchor, and a bridge between the proximal and distal anchors. The bridge has an elongated state, having first axial length, and a shortened state, having a second axial length, wherein the second axial length is shorter than the first axial length. A resorbable thread may be woven into the bridge to hold the bridge in the elongated state and to delay the transfer of the bridge to the shortened state. In an additional embodiment, there may be one or more central anchors between the proximal and distal anchors with a bridge connecting adjacent anchors.

  • Publication number: 20050080483
    Abstract: A device for reshaping a cardiac valve (26), which is elongate and has such dimensions as to be insertable into a cardiac vessel (24). The device has two states, in a first state (K) of which the device has a shape that is adaptable to the shape of the vessel (24), and to the second state (k?) of which the device is transferable from said first state (K). Further, the device comprises a fixing means (22,23;22a,23a) for fixing the ends of the device within the vessel (24), when the device is first positioned therein, a shape-changing member (20;20a) for transferring the device to the second state (K?) by reshaping it, and a delay means (21;21a) for delaying said reshaping until the fixing of the ends of the device has been reinforced by keeping said device in said first state (K) until the delay means (21;21a) is resorbed.

  • Publication number: 20040116850
    Abstract: A catheter is configured to prevent kinking of a catheter during handling or mounting of a pressure device. The catheter has a proximal end of its catheter shaft that is provided with a bending section having a flexibility greater than that of the section of the catheter shaft joining the proximal end.
