Abstract
The invention provides a stent is made from a material operable to perform a stent's desired therapeutic functions, and also made from a material that has a radioopacity that substantially preserves the appearance of the stent when the stent is viewed under a CT
imaging beam. Such a stent can allow for follow-up of the stent and the surrounding blood-vessel on CT.
imaging beam. Such a stent can allow for follow-up of the stent and the surrounding blood-vessel on CT.
Claims (23)

17. The device according to claim 1 wherein said imaging system is a substantially real-time CT machine.
18. The device according to claim 17 wherein said device is the Toshiba Acquillion.
19. An imaging processing unit for a CT machine comprising:
a means for receiving mutli-plane images of mammalian tissue;
a database of known medical devices and associated properties of said devices, at least one of said devices being selected from the group of devices for the treatment of obstruction due to clot, plaque, atheroma, tumours, and treatments involving intimal hyperplasia and recurrent stenosis;
a means for determining whether an object detected in said received images matches with a known medical device in said database, said means for determining based on said associated properties;
means for applying a filter to said received images to enhance an image of said tissue that surrounds said implanted medical device based on said known associated properties; and, means for presenting said image on an output device.
a means for receiving mutli-plane images of mammalian tissue;
a database of known medical devices and associated properties of said devices, at least one of said devices being selected from the group of devices for the treatment of obstruction due to clot, plaque, atheroma, tumours, and treatments involving intimal hyperplasia and recurrent stenosis;
a means for determining whether an object detected in said received images matches with a known medical device in said database, said means for determining based on said associated properties;
means for applying a filter to said received images to enhance an image of said tissue that surrounds said implanted medical device based on said known associated properties; and, means for presenting said image on an output device.
20. The processing unit of claim 19 wherein said associated properties include a Hounsfield unit measurement of said device.
21. The processing unit of claim 20 wherein said medical devices have a density of less than about 1200 Hounsfield units.
22. A medical device comprising an expanding balloon mounted to a self expanding stent, said stent being releasably restrained by a plurality of breakable polymeric bands surrounding said stent and said balloon; said balloon for breaking said bands when said balloon is inflated to thereby free said stent for deployment; said polymeric bands for restraining plaque and potential embolic material from forming behind said stent.
23. The device according to claim 22 wherein said bands are coated with at least one drug.
