Streamlined treatment of clot removal, angioplasty and prevention of restenosis using a single integrated intravascular device
Abstract:
A single integrated intravascular device including a stentriever and semi-compliant balloon housed therein. After traversing a clot, the device is deployed to a self-expanded state engaging the clot therein, whereupon the device along with the embedded clot is removed. Detecting through imaging a stenosis at an original position of the captured clot, the device is reintroduced to that location and the stentriever is deployed to a self-expanded state. Inflating the semi-compliant balloon enlarges the stentriever to a hyper-expanded state greater than the self-expanded state thereby dilating the vessel while simultaneously completely detaching/releasing the stentriever from a remaining portion of the device. Then the semi-compliant balloon is collapsed and withdrawn along with the remaining portion of the device, while the detachable/releasable portion of the stentriever in the self-expanded state remains in the vessel.
