The device uses medical-grade stainless steel and looks similar to most commercial stents inside the drift of blood through artery.

now, a team led via ubc electric and computer engineering professor kenichi takahata has developed a kind of "clever stent" that video display units even subtle changes inside the drift of blood through the artery, detecting the narrowing in its earliest degrees and making early diagnosis and remedy possible.

"we changed a stent to characteristic as a miniature antenna and brought a special micro-sensor that we evolved to constantly tune blood glide. the statistics can then be despatched wirelessly to an external reader, imparting constantly updated information on the artery's circumstance," stated takahata.

the device makes use of scientific-grade chrome steel and appears just like most commercial stents. researchers say it's the primary angioplasty-ready smart stent -- it is able to be implanted using modern-day clinical approaches with out adjustments.

research collaborator dr. york hsiang, a ubc professor of surgical treatment and a vascular physician at vancouver popular hospital, referred to that monitoring for restenosis is critical in handling heart disorder.

"x-rays such as ct or diagnostic angiograms, that are the usual gear for analysis, may be impractical or inconvenient for the affected person," said hsiang. "placing a clever stent in place of a widespread you will permit physicians to monitor their patient's fitness greater without difficulty and provide remedy, if wished, in a timely way."

the device prototype was effectively tested in the lab and in a swine model. takahata, who holds patents for the technology, says his group is planning to set up enterprise partnerships to further refine the device, placed it via medical trials and in the end commercialize it.
