AI Technical Summary
Technical Problem
Conventional neurovascular stents face challenges in navigating tortuous vasculature, are non-compliant, and have predetermined radial strengths that can lead to complications such as in-stent stenosis, thrombosis, and poor support of the target vasculature.
Method used
An intravascular device with an inner stent and outer stent configuration that allows for adjustable radial strength, enabling easy navigation and deployment by fusing the inner stent to the outer stent using energy, such as electric current, to set the radial strength in situ.
Benefits of technology
The device provides improved deployment success and compliance by allowing adjustable radial strength, reducing complications and enhancing support in various anatomies.

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.
