    摘要： A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.

    摘要： A method of coating a stent comprises contacting a first axial portion of a stent with a support element, such that a second axial portion does not contact the support element or any other support element, applying a coating material to the second axial portion, and inhibiting or preventing application of the coating material on the first axial portion. A shuttle sheath can be used to push the stent off the support element.

    摘要： A process for crimping stents includes a multi-stage process producing a desired stent retention and crimped profile in a reduced amount of time. The process achieves results by utilizing particular combinations of heat and pressure during the crimping process, which was found to produce the desired results.

    摘要： Systems, methods and apparatus for acquiring an image from within a body lumen are provided. Systems embodying features of the invention include an intracorporeal imaging component for acquiring imaging information, an image information recording component, and an image information playback component. Methods for acquiring image information from within a body lumen include steps of acquiring imaging information, storing image information, and playing back imaging information. Imaging information may be played back as acquired, or non-sequentially, or composite images may be formed by combining, filtering, enhancing, or subtracting images and the composite images displayed. Devices embodying features of the invention include optical imaging components such as an optical IGW, an optical imaging recording component, and an optical image playback component. The systems, methods and devices are suitable for use with angiopoplasty, stent delivery, and other intracorporeal clinical procedures.

    摘要： A catheter having an multilayered shaft section with a first layer formed of a polyimide first material and a second layer formed of a second material. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. However, in alternative embodiments, a thermoplastic polyimide is used. The thermoset polyimide has a very high glass transition temperature (Tg) of approximately 400null C. (as measured by differential scanning calorimetry), and excellent dimensional stability at the processing temperature of polyamides commonly used in catheter components. As a result, during formation and assembly of the catheter, production of a thin polyimide layer with controlled dimensions is facilitated. The polyimide has a high modulus and provides a thin walled yet highly pushable shaft section, while the second layer provides kink resistance. In one embodiment, the second material is selected from the group consisting of a polyamide material and a polyurethane material.
