Stentrode (Stent-electrode recording array) is a small stent-mounted electrode array permanently implanted into a blood vessel in the brain, without the need for open brain surgery. It is in clinical trials as a brain–computer interface (BCI) for people with paralyzed or missing limbs, [ 1 ] who will use their neural signals or thoughts to ...
The balloon is removed and the stent remains in place, supporting the inner artery walls in the more open, dilated position. Current stents generally cost around $1,000 to 3,000 each (US 2004 dollars), the drug-coated ones being the more expensive.
A bioresorbable stent is a tube-like device that is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. It is made from a material that can release a drug to prevent scar tissue growth. It can also restore normal vessel function and avoid long-term complications of metal stents. [1] [2]
The major benefit of drug-eluting stents (DES) when compared to bare-metal stents (BMS) is the prevention of in-stent restenosis (ISR). [70] Restenosis is a gradual re-narrowing of the stented segment that occurs most commonly between 3–12 months after stent placement. [ 119 ]
Chimney: In TEVAR, a covered stent placed from the ascending aorta to a great vessel (e.g., innominate artery) and adjacent to the main body of the EVAR is termed a chimney. In anatomic position, blood flows superiorly through a chimney-stent graft into the great vessel, just as smoke flows up a chimney.
Carotid artery stenting is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. It is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky.
The amount of range gained per time charging, charging speed, is the ratio of charging power to the vehicle's consumption, and its inverse is the charging time per driven distance:
