    摘要: A system for pulsed synchronized laser cutting of stents and/or other medical products includes a numerical controller and a machine for moving a tube of material during cutting. A pulsed fiber laser is configured to cut the tube into, for example, a stent, the numerical controller being in communication with the machine and configured to send movement control information to the machine. The numerical controller may also receive movement speed information from the machine. The numerical controller is also in communication with the pulsed fiber laser and is configured to send pulse control information to the pulsed fiber laser. The numerical controller is configured to cause average laser power to decrease by decreasing frequency of laser pulses as stent cutting speed decreases, and to cause average laser power to increase by increasing frequency of laser pulses as stent cutting speed increases.

    摘要: An implantable medical device is disclosed having a helical construct including a set of spiral coils for local in vivo application of a therapeutic substance in a biological lumen. The helical construct is configured to apply less than 0.75 Bar of pressure to the biological lumen wall. The helical construct can have at least two sets of spiral coils having opposing helical directions. The device can be used for the treatment of vascular disorders such as restenosis and vulnerable plaque.
