Vascular stent with adjustable radial strength

Abstract

An intravascular device may have a first configuration during deployment and a second configuration after deployment. The first configuration has a first radial strength; and the second configuration has a second radial strength. The first radial strength is less than the second radial strength. A system may include an intravascular device; a wire extending through the intravascular device to expand or contract the intravascular device; a proximal hub coupled to the wire; a distal hub coupled to the wire; and a plurality of tethers extending from an input device and through the intravascular device. At least a portion of the plurality of tethers has electrical conductivity. Application of energy to the at least a portion of the plurality of tethers may disengage the plurality of tethers from the intravascular device and fuse a luminal segment of the plurality of tethers, extending through the intravascular device, to the intravascular device.
