Patent ID: 10456160

Abstract:
Assemblies and methods for scoring a stenotic region within a vessel of a patient are disclosed. An assembly can comprise a scoring member and a deployment member. The scoring member can include an elongate push structure and a tubular, self-expanding scaffold. The elongate push structure can be positioned proximal of the self-expanding scaffold and, at its distal end portion, eccentrically coupled with a proximal end portion of the self-expanding scaffold. The deployment member can be removably positioned within a central lumen of the self-expanding scaffold and detachably engageable with a portion of the self-expanding scaffold. The self-expanding scaffold can be movable between a downsized configuration, when receiving axial tension from the deployment member, and an expanded configuration, in the absence of axial tension. The assembly can further comprise means for detachably engaging the deployment member and the self-expanding scaffold and means for detachably engaging the deployment member and the elongate push structure.
