  • Stent having circumferentially deformable struts
    Patent number: 8940037
    Abstract: Disclosed is a method of treating a bodily lumen with a stent, the method comprising: disposing a stent within a bodily lumen, the stent comprising a plurality of deformable struts that are substantially circumferentially aligned and are configured to selectively deform in a circumferential direction in localized regions in the struts upon application of an outward radial force; and expanding the stent by applying the outward radial force, wherein the outward radial force causes selective deformation of the deformable struts in a localized region in the struts.

  • Methods for improving stent retention on a balloon catheter
    Patent number: 8925177
    Abstract: A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.

  • METHODS AND DEVICES FOR CRIMPING SELF-EXPANDING DEVICES
    Publication number: 20140283349
    Abstract: Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.
