    Abstract: A method of forming an expandable member for a medical device, and particularly a balloon for a catheter, in which extruded tubing is first expanded in a continuous or a semi-continuous process to form expanded tubing, and then the expanded tubing is further expanded in a balloon mold to form the catheter balloon. The method generally includes expanding a long length of tubing from a first inner and outer diameter to a second larger inner and outer diameter, to form expanded tubing having an expanded intermediate diameter, and processing the expanded tubing to form a plurality of expanded intermediate diameter tube segments, each segment having a length significantly shorter than the length of the expanded tubing. One of the segments is then placed in an inner chamber of a balloon mold, and expanded in the balloon mold to form a balloon for a catheter.

    Abstract: The invention is directed to adjustable length mold assemblies for forming inflatable members and methods for using adjustable length mold assemblies for forming inflatable members, such as, for example, balloons for use with balloon catheters and stent delivery systems. The adjustable length mold assemblies comprise at least two mold pieces adapted to fit together, one mold piece having a surface configured to be slidably received by a bore of the other mold piece, the placement of one piece within the other defining a chamber of variable length which forms the mold. Each adjustable length mold assembly of the present invention is effective to form balloons, where if desired different balloons formed by a single mold may have different lengths. The adjustable length mold assemblies may also comprise a positioner to put a mold piece in a desired position relative to the other, and a locking mechanism to secure a mold piece in a desired position.

    Abstract: The present invention is directed to apparatus and method for forming balloons with improved dimensional stability and balloons formed by the same. The method of the present invention provides for a very accurate control of the temperature profile of the balloon material during its making. The attributes of the balloon can be affected by how the balloon is treated during the blowing stage and after the initial blowing, i.e., heat-setting. Using the present method, the balloon will form more uniformly and evenly (e.g., wall thickness and outer diameter of the balloon). The present method significantly increases the dimensional stability of the balloon which provides a balloon that is more predictable in use. The present heat-set process also provides the means for the working length to be located more accurately on dilation catheters and stent delivery systems.

    Abstract: A balloon catheter having an elongated shaft and a balloon mounted on the distal portion of the shaft, the balloon having a working section and proximal and distal end portions that extend inwardly with respect to the working section and which are secured to the catheter shaft within the working section. The end portions are therefore inverted recesses on each end of the balloon. A stent may be disposed about the balloon to form a stent deploying system. The proximal and distal end portions may contain a tapered portion, which tapers from the balloon working section to the catheter shaft with decreasing transverse dimension. The end portions may be connected to the working section with connecting fibers. This design allows for improved expansion and stent placement in the vasculature.

    Abstract: An improved guidewire for advancing a catheter within a body lumen which has a high strength proximal core section, a flexible distal core section preferably formed of pseudoelastic alloy and a connecting element to provide a torque transmitting coupling between the distal end of the proximal core section and the proximal end of the distal core section. The ends of the core sections are secured within the inner lumen of the connecting element by means of a hardened mass of bonding material. The wall of the connecting element is provided with an opening to facilitate the introduction of the hardenable bonding material in the pourable state into the inner lumen of the connecting element. Preferably at least one of the ends of the core sections are configured, e.g. enlarged in at least one dimension compared to an adjacent part of the core section, to develop a mechanical interlock within the mass of hardened material.

    Abstract: A guidewire having a core section formed of a NiTi alloy which is in an austenite phase when being manufactured but which is converted to the martensite phase at operating (body) temperature (37null C.) and can be transformed to an austenite phase by heating to a temperature above body temperature but below 50null C. When in the austenite phase, the core section is at a high strength level which ensures the tracking of a catheter over the guidewire within a patient's body lumen. In one preferred embodiment the core section is heated by electrical resistance or inductance
