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.

Apparatus for sealing a puncture by causing a reduction in the circumference of the puncture

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.

Method and device for treatment of mitral insufficiency

A catheter basically has a catheter shaft in which a catheter tip of which is provided with a joint made of a material which is more flexible than the material of the catheter shaft. The joint is disposed between the distal end of the catheter shaft and the distal end of the catheter tip. The front end consists of a material being the same or more rigid than that of the catheter shaft.

Catheter and method of manufacturing same

Apparatus is provided for sealing a puncture within a vessel or tissue to provide hemostasis, comprising a first disk coupled to either a second disk or a spring, and sealingly engaged to the vessel or tissue surrounding the puncture. At least the first disk is preferably configured to substantially conform to the profile of the vessel or tissue when deployed. In one embodiment, the disks may be released from engagement with the vessel or tissue to reposition the disks after deployment.

Apparatus for sealing surgical punctures

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.

Method for connecting a catheter balloon with a catheter shaft of a balloon catheter

A catheter balloon is configured to improve its fold-in or collapsing behavior. The catheter balloon has a balloon body portion, a first tapered end portion and a second tapered end portion. The balloon body portion has a substantially cylindrical shape in an expanded state. The first tapered end portion is formed at a first end of the balloon body portion. The first tapered end portion includes a first predetermined embossment. The second tapered end portion is formed at a second end of the balloon body portion. The second tapered end portion includes a second predetermined embossment. The balloon body portion is formed free of a predetermined embossment. In other words, the balloon body portion is formed without folds so that there is only predetermined folding on the conical end portions for inducing the folding of the balloon body portion in a predetermined direction upon collapsing.

Catheter balloon

A device for reshaping a cardiac valve (), which is elongate and has such dimensions as to be insertable into a cardiac vessel (). 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 (), and to the second state (k') of which the device is transferable from said first state (K). Further, the device comprises a fixing means () for fixing the ends of the device within the vessel (), when the device is first positioned therein, a shape-changing member () for transferring the device to the second state (K&#x2032;) by reshaping it, and a delay means () 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 () is resorbed.

Apparatus for applying a compressive load on body tissue

The invention includes a catheter having an elongate main body having a proximal section and a distal section. The elongate main body further includes a plurality of stiffening members disposed along the length of the elongate main body. At least one stiffening member includes a plurality of clusters including helical turns or rotations disposed circumferentially about a tubular member and along the length of the cluster. The clusters can be configured to vary flexibility along the length of the tubular member. The catheter can include a sheath having a stationary section and a retractable section.

Catheter having plurality of stiffening members

The invention provides a catheter and method of making the same including an outer tubular member having a length, an outer surface, an inner surface and a lumen therethrough. The catheter also includes an inner tubular member having an outer surface, an inner surface and a lumen therethrough, at least a length of the inner lumen is disposed in the lumen of the outer tubular member. The catheter also includes a support member biasing a portion of the outer surface of the inner tubular member against a portion of the inner surface of the outer tubular member.

Multiple lumen catheter and method of making same

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 colored 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.
