Covered stents carry the advantage of preventing tumours from growing into the stent, although they run the risk of increased migration after deployment. [6] A plastic self-expanding stent (Polyflex, Boston Scientific) has also been developed for similar applications. It confers an additional advantage as it is designed to be removable, and may ...
Although a permanent prostatic stent is not a medical treatment, it falls under the classification of a surgical procedure. [3] Placement of a permanent prostatic stent is carried out as an outpatient treatment under local, topical or spinal anesthesia and usually takes about 15–30 minutes.
Coronary stents are placed during a coronary angioplasty.The most common use for coronary stents is in the coronary arteries, into which a bare-metal stent, a drug-eluting stent, a bioabsorbable stent, a dual-therapy stent (combination of both drug and bioengineered stent), or occasionally a covered stent is inserted.
Knowing you have cancer but hearing that you don’t need treatment can cause anxiety for patients, Dr. Kakadia admits. “It’s a life-changing event, and that’s why we discuss the options.”

1960s – Radioisotopes such as Yttrium-90 (Y90) started to be investigated for the use in cancer treatments. 1966 – Embolization therapy to treat tumors and spinal cord vascular malformations by blocking the blood flow. 1969 – The catheter-delivered stenting technique and prototype stent.
Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel through the healing process. However, in the case of a bioresorbable stent, the stent will gradually resorb and be benignly cleared from the body, enabling a natural reconstruction of the arterial wall and restoration of vascular function.
