Abstract

Percutaneous medical procedures are provided, which use endovascular instruments to install mechanical closures for closing vessels, such as veins. The mechanical closures can be one or more sutures that are anchored to the vessel walls and then cinched to closed the vessel. The mechanical closures can also be resilient clips or stents that are expanded within the vessel to pierce the vessel walls, and are then contracted to pull the vessel closed. Various techniques for installing the mechanical closures are also described.
