摘要： A stent or other luminal prosthesis is delivered by a catheter having a contoured balloon. The contoured balloon may include a central dome region flanked by at least one adjacent flat or cylindrical region. The central domed region and adjacent flat or cylindrical regions are joined at shallow angles to provide for an incrementally larger expansion of the center region of the stent while minimizing shear forces during expansion.

摘要： A device and methods for applying treatment to a flow obstruction are provided herein. The device has a treatment layer with operable elements. The operable elements are mechanically activated upon bending of the flexible layer beyond a specified curvature threshold due to contact of the treatment layer with the obstruction. Positioning the device onto the lesion activates the operable elements by the sheer mechanical bending of the device, which causes e.g. opening of holes toward the lesion, perforation of the lesion, focusing of energy onto the lesion etc. The activation of the operable elements applies the treatment to the obstruction, and as the lesion is removed, the bending of the device decreases until the application of the treatment is mechanically stopped by the resulting de-activation of the operable elements.

摘要： Inflatable devices are disclosed including a surface which has a network of polymer chains and is configured to be inflatable into a therapeutically or diagnostically useful shape, and at least one ultrashort laser pulse-formed modification in the surface. The network can, for example, include a network morphology that is substantially unchanged by modification with the ultrashort pulse laser. Ultrashort laser pulses can be laser pulses equal to or less than 1000 picoseconds in duration. Advantageously, the etching process uses a relatively low-heat laser to avoid significant heating of surrounding polymers while modifying the surface (and other structures) of the device. The process is configured so that the polymer chain morphology adjacent the modification is substantially unaffected by the low-heat laser. The resulting inflatable device has customized surface features while still retaining substantially homogenous polymer network morphology. This preserves the elasticity, especially the surface elasticity, of the inflatable device.
