Stent delivery system having a contracted delivery configuration and an expanded deployed configuration is provided. The stent delivery system includes a stent having a plurality of expandable elements and a plurality of interstices disposed between adjacent expandable elements, and a delivery catheter having an inflatable balloon including creases extending non-uniformly within the interstices of the stent in the contracted delivery configuration. Each crease defines a maximum radial height within a corresponding interstice, and the maximum radial heights of the creases vary. A method for stenting at a target site within a patient's vessel including providing a stent delivery system is also provided.

Process for loading a stent onto a stent delivery system

A method of making a stent delivery system is provided in which a delivery catheter has a balloon that extends non-uniformly into interstices of a stent. In accordance with the method a balloon/stent/crimping tube assembly is placed in a crimping tool, the balloon is inflated, and the crimping tool is actuated to compress the stent on the outside of the balloon without application of heat or chemicals, thereby causing creases of the balloon to extend non-uniformly into the interstices of the stent. Optionally, pillows may be formed in the balloon to prevent longitudinal movement of the stent with respect to the balloon during intravascular delivery. One or more secondary crimpings also may be performed to achieve a smoother delivery profile.

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

The invention discloses a balloon catheter comprising a catheter shaft, at the distal end of which an inflatable balloon is arranged and at the proximal end of which a connecting piece is arranged, comprising a guiding wire which can be passed through a guiding wire lumen of the catheter shaft from the proximal end to the distal end and through the balloon and an inflation or deflation lumen extending from the proximal end of the catheter shaft to the balloon, wherein a portion of the catheter shaft having a selectable length and extending from the proximal end is provided with a metal reinforcing pipe.

Balloon catheter

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

In order to enhance the flexibility and trackability of a catheter () that is particularly adapted for use in delivering a stent (), the catheter () comprises a marker arrangement () that includes at least one marker () made from a wire of a highly radiopaque and ductile material. Said wire is preferably wrapped around a second inner tube () of the catheter ().
