    摘要: Medical devices have material that that has a laser induced periodic surface structure (LIPSS) pattern on at least a portion thereof. The LIPSS pattern is provided by exposing a material surface to a pulsed polarized laser energy fluence below the ablation threshold. The LIPSS pattern is useful for purposes such as reducing contact areas on sliding surfaces, increasing total surface area for adhesions, providing anisotropic reinforcement of a material layer or layers, and to provide multiple channels for directing cell growth.

    摘要: A catheter assembly including a side branch locator that is moveable between a retracted position within a main vessel of a vessel bifurcation, and an extended position wherein a distal end of the side branch locator extends into a branch vessel of the vessel bifurcation. The side branch locator includes a first end fixed relative to a portion of the catheter assembly that remains in the main vessel. A second end of the side branch locator is moveable between the retracted and extended positions. The catheter assembly can include a moveable sheath that holds the side branch locator in the retracted position. The catheter assembly can further include a stent having a lateral branch opening through which the side branch locator extends.
