Title:
INTRAVASCULAR DEVICES, SYSTEMS, AND METHODS FOR THE CONTROLLED DISSECTION OF BODY LUMENS
Document Type and Number:
WIPO Patent Application WO/2016/100574
Kind Code:
A3
Abstract:
Devices, systems, and methods for treating damaged or diseased valves are disclosed. A representative embodiment includes an elongated shaft having a longitudinal axis, a proximal portion, and a distal portion, and a dissection arm at the distal portion. The dissection arm can have a longitudinal axis and be moveable between a low-profile state and a deployed state. In the deployed state, a portion of the arm can flex outwardly away from the longitudinal axis of the shaft. The arm is configured to be deployed within a space within a vessel wall such that, as the arm moves from the low-profile state to the deployed state, the arm pushes against vessel wall tissue at a periphery of the space, thereby separating tissue at the periphery to form a dissection pocket having a predetermined shape.
