  • Patent number: 9017376
    Abstract: Apparatus is provided for sealing a vascular puncture by causing a reduction in the circumference of the puncture tract through delivery of a closure agent into tissue surrounding the puncture tract. A resultant inflammatory response and volumetric increase cause the tissue to swell into the puncture tract, thereby sealing it.

  • Patent number: 8709074
    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.

  • Patent number: 8092634
    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: 8075616
    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.
