This disclosure is directed to systems and methods for re-entering the true lumen of a vessel. The re-entry catheters employ deflectable struts to stabilize and support the distal tip in a subintimal location while a passageway back into the true lumen is formed. Re-entry to the true lumen can be effected with a cutting element or with a conventional guidewire.

This disclosure is directed to systems and methods for providing a guiding device having a dilatable, drilling tip. The tip is formed by wound helical members such that resistance to rotation in an unwinding direction dilates the tip. The helical members are configured so that the dilatable tip increases in stiffness when the helical members are tensioned by a resistance to rotation in the winding direction. In some embodiments, application of relative force between coaxial inner and outer tubular members is used to control the dilation, stiffness and drilling of the guiding member.

Described is a remotely programmable control device for use in electroluminescent display and lighting applications. Elements of this invention include a power supply, various inverters/wave form conditioners, a motherboard, inbound/outbound communications capability, motion-sensing devices, ambient light sensing facilities, and a floppy disk reader. Remote programmability is achieved through several methods including detecting the driving instructions from the lamp display itself, or downloading data from a remote network or a floppy disk.
